Sharks!

Sharks are cartilaginous fishes belonging to the subclass Elasmobranchii within the class Chondrichthyes, distinguished by skeletons composed of cartilage rather than bone, skin covered in dermal denticles, and five to seven gill slits on each side of the head. They encompass over 500 extant species across approximately 30 families and 50 genera, exhibiting diverse morphologies from the diminutive Etmopterus perryi measuring under 20 cm to the filter-feeding Rhincodon typus exceeding 12 m in length. The evolutionary lineage of sharks traces back more than 450 million years to the Late Ordovician period, with the earliest fossil evidence consisting of scales and teeth from primitive ancestors, predating bony fishes and tetrapods. Adaptations such as ampullae of Lorenzini for electroreception, a lateral line system for detecting vibrations, and incessant tooth replacement—where rows of replacement teeth lie beneath functional ones—have enabled sharks to thrive as versatile predators in marine environments worldwide. As predominantly and mesopredators, sharks regulate prey populations, cull weaker individuals to enhance genetic in prey , and contribute to overall by occupying critical trophic levels. However, intensified for fins, , and , coupled with , has rendered many vulnerable; assessments indicate that sharks face higher extinction risks than most other groups, with over 150 classified as endangered or .

Background and Conception

Antepavilion Prize Win

In 2020, the SHARKS! project by architect of was selected as the of the fourth , organized by the to temporary, provocative installations along London's that regulations and . The received 135 entries, from which five were shortlisted, with SHARKS! chosen for its bold response to the brief's emphasis on the between "authoritarian " and "aesthetic ." The winning featured six full-scale fibreglass mounted on wooden bases, arranged to appear as if leaping from the in the at Docks, Hackney, equipped with audio systems to broadcast , lectures on , and effects. Inspired by the contentious 1986 —a rooftop in that defied authorities—SHARKS! was intended to satirize bureaucratic opposition to Antepavilions, including Hackney Council's actions against the 2017 and 2019 installations. The prize awarded £25,000, with a requirement that at least 60 percent be allocated to materials and labor for construction on a platform of up to seven NATO-standard pontoons (each 4.2 meters by 2.1 meters), moored at the competition site sponsored by developer Russell Gray of Shiva. Installation was initially slated for autumn 2020, though delayed by the COVID-19 pandemic and subsequent regulatory disputes. The jury praised the entry's surreal humor and potential to spark public discourse on planning freedoms, aligning with the competition's history of installations that test legal boundaries without formal permissions.

Artistic and Conceptual Origins

The Sharks! originated as the winning by Jaimie Shorten in the Antepavilion , an initiative by the aimed at challenging conventional architectural norms through temporary, provocative structures at Hoxton Docks along the in . Shorten's envisioned a pod of full-scale fibreglass sharks dramatically leaping from the , adapting the singular, rooftop of the —a 25-foot (7.6-meter) sculpture installed on August 9, 1986, by Oxford resident Bill Heine on the roof of his home at 2 New High Street, Headington. Heine's shark, fabricated by local artist John Buckley, served as a satirical emblem of existential peril, evoking the sudden destructiveness of aerial bombardment amid Cold War nuclear anxieties and the 1986 U.S. bombing of Libya, with its jaws agape in a mock attack on the domestic structure below. Shorten's multiplication and aquatic repositioning of the motif extended this to critique contemporary rigidities, directly referencing Hackney Council's prior actions against earlier Antepavilions at the , which had been deemed unauthorized developments. The embodied "aesthetic ," positioning disharmonious, eccentric interventions as deliberate acts of against bureaucratic overreach, much like the Headington 's own protracted legal , which culminated in a 1992 Department of the ruling upholding its retention: "the is not in with its surroundings, but then it is not intended to be in with them." This meta-commentary on planning disputes framed Sharks! as a floating tableau of defiance, celebrating the triumph of artistic provocation over regulatory conformity. Conceptually, the sharks transcended passive sculpture by incorporating performative elements—emitting bubbles, vocalizing songs, and broadcasting lectures on urbanism—to foster public engagement and debate on architecture's societal role, aligning with the Antepavilion's ethos of ephemeral structures that interrogate power dynamics in built environments. Shorten's design thus rooted its origins in historical protest art while adapting it to site-specific tensions, prioritizing symbolic disruption over aesthetic integration.

Design and Features

Physical Construction of the Sharks

The Sharks! installation consists of large-scale shark sculptures fabricated primarily from polystyrene foam cores overlaid with fibreglass skins to ensure buoyancy, durability, and resistance to aquatic environments. This construction method allowed the structures to float independently in Regent's Canal while simulating dynamic leaping and lunging poses above the water surface. Each features a interior designed to accommodate integrated and systems, including speakers for lectures and on , machines for , generators, and projectors. The winning proposal specified , though reports indicate five were ultimately prepared and deployed. Fabrication began with 3D digital modeling to create anatomically inspired forms, drawing from the iconic Headington Shark—a full-scale fibreglass sculpture installed on a rooftop in in 1986. Polystyrene cores were then milled using a 7-axis robotic arm at the Pro-Duck workshop in Ramsgate, enabling precise shaping of the lightweight, buoyant bases. These cores underwent hand-finishing, painting for aesthetic detail, and application of fibreglass reinforcements to achieve structural integrity suitable for temporary outdoor exhibition. The largest , dubbed , weighed kilograms and was assembled by Boyes of Propcreator through a of core formation followed by fibreglass , highlighting the demands of up the for performative stability in . Overall, the demountable of the fibreglass-polystyrene composites facilitated , installation, and potential disassembly, aligning with Antepavilion guidelines for non-permanent pavilions budgeted at £25,000.

Interactive and Symbolic Elements

The Sharks! installation featured five full-scale replica sharks—two megalodons, two great , and one —constructed from and fibreglass, positioned as if leaping from the . These sculptures incorporated for dynamic with viewers and the , including machines that emitted and bubbles to simulate disturbance, beams from the sharks' forms, and integrated speakers audio such as , lectures on and , and potentially simulated interviews with figures like psychiatrists or architects. Additional planned effects included fountains inspired by Bernini's , allowing the to reconfigure into performative tableaux, such as echoes of Théodore Géricault's , enhancing visitor through visual and auditory during temporary displays. Symbolically, Sharks! critiqued authoritarian regimes while championing aesthetic , directly referencing the —a fibreglass atop an that prevailed in a protracted dispute against authorities, embodying to regulatory . The installation's surreal, discordant floating mirrored ongoing tensions between artistic and bureaucratic , positioning the sharks as predatory emblems of challenging institutional over the , much like the Antepavilion project's own conflicts with Hackney . This conceptual framework underscored a broader advocacy for liberating architecture from prescriptive governance, using the sharks' predatory imagery to highlight the disruptive potential of unapproved aesthetic acts in urban spaces.

Installation Attempt and Initial Response

Deployment at Hoxton Docks

The "Sharks!" installation, consisting of five large fibreglass sculptures depicting great white sharks, was designed for deployment on floating platforms in the Regent's Canal adjacent to Hoxton Docks in Hackney, London. Following Jaimie Shorten's win of the 2020 Antepavilion competition on March 27, 2020, construction began under the supervision of developer Russell Gray of Shiva, who owned the Hoxton Docks site. The sharks, each approximately 4 meters long, were engineered with integrated speakers for audio playback, smoke machines, and laser projectors to create dynamic effects symbolizing urban intrusion into natural waterways. Deployment commenced in August 2020, with four of the sharks positioned on rafts and floated into the canal by August 28, marking the initial public visibility of the work. The platforms were anchored near the Hoxton Docks complex at 55 Laburnum Street, allowing the sculptures to appear as if leaping from the water toward the urban shoreline. Installation of the fifth shark was underway on dry land adjacent to the site when Hackney Council obtained an interim injunction from the High Court on August 24, 2020, suspending further work pending a full hearing. This legal intervention, initiated due to alleged breaches of planning permissions for structures on the water, left the partial deployment in limbo, with the floated sharks remaining visible but non-operational. The deployment highlighted tensions between temporary and regulatory frameworks, as the Antepavilion brief specified non-permanent installations to avoid full requirements. Despite the halt, the visible sharks drew early along the towpath, though full of interactive like synchronized and shows was never realized at the . Subsequent court rulings in September 2020 ordered the removal of the structures, effectively ending the Hoxton Docks deployment.

Immediate Public and Official Reactions

Hackney London Borough Council responded immediately to the partial deployment of four fibreglass sharks into the near Hoxton Docks on , , by securing an interim from the that same day. The council contended that the represented a "material change of use" of the , necessitating , and halted the placement of the fifth shark while prohibiting of audio, smoke, and laser effects. This extended prior enforcement efforts against Antepavilion projects at the site, framing the sharks as unauthorized structures rather than temporary art. Public reception contrasted sharply, with passersby along the canal expressing amusement at the sight of the pontoon-mounted sculptures—two great whites, one , and two megalodons—before full effects were operational. Within the architecture and communities, the council's intervention drew criticism as disproportionate; Antepavilion juror Gray labeled it "pathetic" and suggestive of bureaucratic scrambling triggered by media attention. Jaimie Shorten, the installation's creator, voiced surprise at the escalation, noting it deviated from expectations of dialogue despite Hackney's history of planning tensions with local artists. Early media coverage amplified support for the project as a provocative commentary on regulatory constraints, portraying the sharks as a whimsical challenge to conformity in public spaces.

Hackney Council's Enforcement Actions

In August 2020, the London Borough of Hackney issued an enforcement notice targeting the display of art installations at Hoxton Docks, specifically aimed at the "Sharks!" project, which the council deemed a material change of use requiring planning permission rather than a permissible temporary artistic display. On August 20, 2020, Hackney secured an interim injunction from the High Court prohibiting further installation or operation of the fibreglass sharks, arguing that the structures—intended to emerge from the Regent's Canal with features like singing, speeches, smoke, and bubbles—constituted an unauthorized operational development on the site. This followed the partial deployment of four sharks, which had begun without prior council approval despite the site's history of hosting Antepavilion works. The council's application emphasized that the installation breached planning controls established after prior enforcement against rooftop structures from earlier Antepavilions in , reinforcing a policy against recurrent unpermitted alterations at the docks. On September 24, 2020, Justice Holgate ruled in Hackney's favor, granting a permanent to prevent the sharks' use for performative , describing the as exceeding mere artistic exhibition by involving structural and functional changes to the waterway and surrounding area. The judgment highlighted the council's evidence of potential harm to the site's conservation area status and navigational safety on the canal, leading to the mandatory removal of the installed sharks by November 2020. Hackney's actions were part of a broader enforcement campaign, including a 2019 notice against four prior structures, which a 2021 planning inspector partially upheld, limiting future displays to nine-month temporary permissions under strict conditions. Critics, including Antepavilion organizers, attributed the council's rigor to bureaucratic overreach, estimating public costs exceeding £100,000 in legal fees for the "Sharks!" dispute alone, though Hackney maintained the measures protected regulatory integrity against repeated non-compliance. In a subsequent development, a planning appeal quashed the 2020 enforcement notice in early 2025, allowing potential reinstallation, but this did not retroactively alter the initial prohibitive actions.

Court Cases and Judicial Rulings

In 2020, the London of Hackney obtained an interim from the against Shiva , the lessee of the Hoxton Docks , and Antepavilion , prohibiting further of the "Sharks!" artwork and requiring preservation of the pending a full hearing. The argued that placing fibreglass sharks on pontoons in the constituted a material change of use under section 55 of the Town and Country Planning Act 1990, as it exceeded incidental use ancillary to the site's permitted B1 commercial operations and lacked planning permission. On 23 September 2020, Mr Justice Murray, in The Mayor and Burgesses of the London Borough of Hackney v Shiva Limited & Ors EWHC 2489 (QB), upheld and extended the injunction following the return date hearing. The judge found a serious issue to be tried, determining that the installation represented an unauthorized operational development or change of use, given its scale—four sharks already placed, with plans for a fifth—and potential for ongoing public interaction, including musical elements. He weighed the balance of convenience in favor of the council, citing the defendants' history of non-compliance with prior enforcement notices and the risk of irreversible harm to planning control if removal were delayed, while noting that dismantling the pontoon-mounted structures would not impose undue hardship. Mandatory relief was granted, ordering the removal of the four installed sharks within 14 days, with prohibitory orders preventing completion or similar displays until planning permission or further court order. In June 2021, Antepavilion Trust successfully challenged a on the via , securing a ruling that —undertaken at Hackney Council's behest to enforce removal—was unlawful to lack of proper . The awarded £60,000 in compensation for legal costs and , though this addressed procedural overreach rather than the underlying merits. No subsequent High Court rulings directly overturned the 2020 injunction on the "Sharks!" installation itself, which was dismantled shortly after the September order. Hackney Council maintained that the installation of the Sharks! sculptures constituted a material change of use of the land under Section 55 of the Town and Country Planning Act 1990, as it involved placing large fibreglass structures on pontoons in the Regent's Canal, thereby altering the site's ancillary artistic activities beyond the permitted B1 office/studio use and requiring planning permission. The council further argued that this amounted to operational development and building operations, given the engineering required for the pontoons and shark fixings, which intensified the site's unauthorized use in a conservation area and potentially harmed heritage assets under Section 72(1) of the Planning (Listed Buildings and Conservation Areas) Act 1990. They rejected claims of artistic exemption, asserting that no precedent, such as the unpermitted Headington Shark sculpture in Oxford, overrode statutory planning controls, and emphasized the risk of proliferation without enforcement. In response, the defendants, including Ltd and Antepavilion organizers, contended that the Sharks! display was ancillary to the site's long-established B1 use, with over 25 years of similar temporary installations at Hoxton Docks that had been tolerated by the , thus not triggering a change of use. They argued the was temporary and sculptural in , akin to non-operational like the , lacking the permanence or to constitute operational or require , and noted the absence of objections from the Canal & River Trust as evidence against significant intensification. Antepavilion further invoked artistic freedom and cultural value, challenging the under Section 187B of the Town and Country Planning Act 1990 by highlighting the 's prior knowledge and acceptance of site activities, positioning enforcement as an overreach against established creative expression rather than a genuine planning breach. In subsequent proceedings, including a ruling granting the , the council's case on change prevailed, with the finding the of favored removal pending full , though defendants secured of permission to in 2021. Antepavilion's appeals emphasized historical use for mixed purposes, including displays, ultimately leading to a planning inspector's decision quashing the council's notice against such installations in early 2022, affirming retrospective elements of the site's operational mix.

Broader Implications and Criticisms

Critiques of Bureaucratic Overreach

Critics of Hackney Council's response to the Sharks! installation argued that the rapid issuance of a High Court injunction on August 21, 2020, represented an disproportionate exercise of regulatory power against a temporary artwork designed for public engagement rather than permanent alteration. The installation, comprising five fibreglass sharks equipped with speakers, lasers, and smoke effects, was intended to last one year as part of the Antepavilion competition, yet the council classified it as a "material change of use" requiring full planning permission, echoing enforcement against prior temporary pieces like the 2019 Potemkin Theatre. Antepavilion founder Russell Gray described the council's intervention—issued after four sharks were already installed—as "pathetic," attributing it to planners' resentment toward smaller, independent projects overruled by larger developers, rather than genuine safety or conservation concerns in the Hoxton Docks area. Proponents of the artwork highlighted the financial burden on taxpayers, with the expending tens of thousands of pounds on that culminated in the sharks' removal by , 2020, despite the installation's minimal environmental and with the site's 25-year of unpermitted art displays. This , critics contended, exemplified how rigid laws under the Town and 1990 stifle innovative by treating ephemeral structures as "development," potentially discouraging future interventions without resources for prolonged litigation. The case drew parallels to the 1986 Headington Shark dispute in Oxford, where a rooftop sculpture endured a six-year battle before prevailing, underscoring a pattern of initial bureaucratic resistance to provocative yet harmless expressions. By , the council's was quashed on , with organizers noting the authority's implicit admission of wasted resources after over three years of contention, further fueling arguments that such actions prioritize procedural over cultural . Detractors maintained that the Sharks! project's explicit —to " " through interactive —made the council's opposition self-defeating, as it amplified of regulatory barriers to spontaneous without of proportional .

Defenses of Regulatory Necessity

Hackney defended its enforcement actions against the Sharks! installation by asserting that it represented a flagrant of under the Town and , constituting both operational development—through the fixing of fibreglass sharks to pontoons in the —and a change of use by altering the waterway's primary from to artistic without requisite permission. The emphasized that prior ancillary artistic uses at the site since 1995 did not exempt the Sharks! project, which intensified the scale and impact, occupying approximately 61 square meters of canal space and introducing fixed structures that exceeded incidental activities under permitted B1 commercial use. Regulatory proponents, including officers, argued that unchecked installations posed tangible risks to and on the shared , where the floating pontoons and leaping shark models could obstruct boat and compromise along the . Features such as machines, beams, and amplified audio—intended to broadcast lectures, speeches, and renditions of like " "—further justified to mitigate disturbances to residential in adjacent and potential hazards from emissions near paths. The , in its September 18, 2020, ruling by ( EWHC 2489 (QB)), affirmed the of these controls by granting a permanent prohibiting full deployment and ordering the removal of partially installed components, finding a "serious to be tried" on the planning breaches and that the balance of convenience favored enforcement to avert irreversible harms. The judgment underscored that artistic expression does not confer immunity from statutory planning requirements, particularly in a designated conservation area where the installation inflicted "less than substantial" harm to the heritage setting of Haggerston Bridge and the broader Regent's Canal character. This outcome highlighted the regulatory framework's role in preventing selective non-compliance, given the site's history of two prior outstanding enforcement notices against the property owner, Shiva Ltd., which rendered traditional remedies potentially ineffective. Planning experts and legal commentators have cited the case as exemplifying the imperative for proactive to uphold the in urban environments, where exemptions for "temporary" or cultural projects could controls for coordinated , , and equitable . Without such measures, authorities argued, proliferation of unauthorized structures in sensitive waterways could cascade into broader degradation of navigational and heritage assets, prioritizing verifiable over subjective claims of anti-authoritarian .

Reception and Cultural Impact

Media Coverage and Public Support

The "Sharks!" installation garnered significant media attention starting in early 2020, with initial coverage emphasizing its whimsical and provocative as the of the Antepavilion 4 . featured a on , 2020, portraying the five fibreglass sharks—equipped with speakers for lectures, machines, and beams—as a surreal in Regent's Canal, highlighting architect Jaimie Shorten's intent to critique planning bureaucracy through anti-authoritarian spectacle. This piece, which noted the sharks' partial deployment at Hoxton Docks, framed the project as a bold artistic statement amid London's regulatory landscape, drawing on Shorten's prior rooftop disputes with Hackney Council. As the legal conflict escalated, architecture and design outlets amplified criticism of Hackney Council's intervention, often depicting it as stifling creativity. Dezeen reported on August 21, 2020, that the council's injunction—prompted partly by sensational "man-eater" headlines—left one shark stranded inside Hoxton Docks, with Antepavilion organizers labeling the authority "pathetic" for prioritizing enforcement over temporary art. The Architects' Journal covered the August 24, 2020, court order halting completion, underscoring the tension between ephemeral public art and planning permissions. Later, The Telegraph on November 25, 2020, described the saga as a clash between a "roguish architect" and a "humourless" council, sympathizing with the installation's removal as an overreach that tested public art's limits. Local outlets like the Hackney Gazette focused on the November 10, 2020, shark removal following the injunction, presenting a more procedural view aligned with council arguments on unauthorized land use changes. Public support for "Sharks!" emerged strongly within artistic and architectural communities, evidenced by letters submitted during the , which Antepavilion cited as backing the project's cultural against regulatory hurdles. and forums reflected intrigue and , with users in 2023 praising the "amazing" and free dance tied to prior Antepavilions, while 2024 posts celebrated the sharks' to Hoxton Docks after four years of disputes. The project's relocation to Islington's City Road Basin in April 2021 sustained , fostering positive from canal users who viewed it as harmless rather than nuisance. By February 2025, the quashing of Hackney's via planning appeal reinforced perceptions of vindication, with Antepavilion updates noting renewed deliberations on reinstallation amid broader advocacy for demountable art. While lacking formal polls, this grassroots enthusiasm contrasted council concerns over safety and precedent, highlighting a divide where creative sectors prioritized expressive freedom.

Artistic Legacy and Influences

The Sharks! by Jaimie Shorten draws from the , a 7.6-meter fibreglass on a residential in in 1986 by Heine without , which symbolized defiance against following its successful against Council's in 1992. Shorten's design adapts this motif to a watery context, featuring five life-sized fibreglass sharks moored on a pontoon in , programmed to emit smoke, bubbles, sing tunes such as "Les Champs-Élysées," and deliver automated lectures on urbanism and architecture, aligning with the 2020 Antepavilion theme of "the tension of authoritarian control and the individual." This conceptual extends of using as a provocative emblem of and in , echoing Heine's original to express ", desperation, and a for " amid tensions like the and of . Shorten's work amplifies the interactive and performative , transforming static into a dynamic, sound-emitting ensemble that critiques regulatory constraints on ephemeral art, funded at £25,000 through the Antepavilion competition sponsored by the Architecture Foundation. In terms of legacy, Sharks! has reinforced Antepavilion's in , prompting architectural on whether temporary installations constitute "buildings" to full permissions or protected expressions under artistic freedoms, as evidenced by subsequent entries referencing shark motifs in 2025 shortlists and the quashing of Hackney's 2020 enforcement notice against art displays in January 2024. The project's forced to Islington in April 2021 and partial temporary approvals thereafter underscore its as a in the friction between public art's disruptive potential and local authority oversight, influencing debates on permitting rogue interventions to foster urban vitality without compromising safety or conservation. While not spawning direct imitators on a large scale, it exemplifies how site-specific provocations can elevate planning disputes into broader critiques of institutional rigidity, akin to the Headington Shark's transformation into a protected local landmark.

Recent Developments and Status

Post-2020 Updates and Attempts to Revive

Following the High Court's September 2020 ruling upholding Hackney Council's injunction, the partially installed Sharks! structures were removed from Hoxton Docks by November 2020. Antepavilion Trust appealed the related enforcement notices to the Planning Inspectorate, challenging the classification of the installations as unauthorized developments requiring planning permission rather than temporary public art. In January 2022, Luke quashed one targeting prior Antepavilion structures at the ( 2017 and from 2019) and granted for their retention, citing their cultural and minimal visual in the area. This decision did not directly address but bolstered arguments for treating Antepavilion projects as exempt from building regulations under permitted for temporary displays. However, over the overall led Antepavilion to postpone its indefinitely that year, relocating entries temporarily while pursuing further appeals specific to . Efforts to revive Sharks! continued through reapplications for consent. In 2023, Antepavilion submitted plans for a "reincarnation" of the installation, proposing five fibreglass sharks on floating platforms with audio features, framed as a seasonal public artwork to test boundaries between art and architecture. When Hackney Council failed to determine the application within statutory timelines, a planning inspector in early 2024 granted temporary nine-month permission (until late 2024) for mooring the models in the freshwater dock, allowing partial reinstallation without full operational elements like speakers or lasers. By February 2025, the Planning Inspectorate quashed Hackney Council's broader enforcement notice against art installations at Hoxton Docks, affirming that the display did not constitute operational development under planning law and could proceed as temporary public art. This enabled full revival efforts, with a single shark initially floated for testing and plans advanced for the complete set by spring 2025. Installation recommenced in mid-2025, with all five sharks returned to the canal by July, restoring the original concept amid ongoing monitoring for compliance with temporary consent conditions. These developments highlighted persistent tensions over defining "art" versus "structure" in UK planning enforcement, with Antepavilion arguing the council's actions exemplified overreach against experimental architecture.

Ongoing Debates as of 2025

As of 2025, a primary centers on addressing shark depredation—the where sharks remove fish from recreational and lines—pitting fishing interests against priorities. The SHARKED , reintroduced in the U.S. in spring 2024 and advanced in the by 2025 with bipartisan sponsorship from Senators (R-FL) and (D-HI), proposes a national task force to study deterrents, education, and management strategies without mandating culls. Supporters, including the Theodore Roosevelt Partnership, argue it promotes science-based collaboration to mitigate economic losses for anglers, estimated in millions annually from lost catch, without broad population reductions. Critics, such as Earthjustice and Shark Stewards, contend the legislation risks serving as a gateway to lethal measures like targeted removals, potentially exacerbating declines in vulnerable species amid ongoing overfishing pressures, and lacks robust ecological safeguards. Internationally, proposals at the Convention on International Trade in Endangered Species (CITES) Conference of the Parties in 2025 seek stricter trade controls on up to 70 shark species, including listings for those threatened by finning and bycatch. Advocates highlight empirical data showing 37% of shark species facing extinction risk due to unsustainable harvest, urging binding export quotas to enforce causal links between trade volume and population crashes. Opponents, often from fishing-dependent economies, argue such measures overlook localized sustainability efforts and could displace pressure to unregulated markets, though peer-reviewed analyses emphasize that without global coordination, regional protections fail against migratory species' exploitation. In Australia, a in reignited contention over lines and nets in and , which 203 sharks and rays in the 2024-2025 but also significant bycatch including and dolphins. Proponents of retention cite reduced attack rates in netted areas since the 1930s, attributing safety gains to direct predator removal despite . Conservation groups with indicating nets prevent fewer than 20% of approaches while amplifying ecosystem disruptions, advocating non-lethal alternatives like SMART drum lines or surveillance drones, which empirical trials show comparable risk reduction with minimal collateral damage. This tension underscores broader causal realism: human coastal expansion heightens encounters, yet lethal controls may undermine long-term marine stability without addressing root drivers like habitat loss.
