Pollachius pollachius

Pollachius pollachius, commonly known as the pollack, is a species of marine ray-finned fish belonging to the cod family Gadidae, characterized by a protruding lower jaw without a chin barbel, three dorsal fins, and a dark lateral line that curves over the pectoral fin, with a body color ranging from dark green or brown on the back to silver-gray sides and a pale underside.^[1]^[2] Adults typically reach a maximum length of 130 cm and weight of 18.1 kg, though common sizes are around 75 cm, with a lifespan of up to 13 years and sexual maturity at approximately 41-42 cm.^[1]^[3] This benthopelagic species inhabits coastal and offshore waters of the northeast Atlantic Ocean, from Iceland and the southern Baltic Sea to the Bay of Biscay, at depths usually between 40 and 100 m (up to 200 m), preferring areas with hard, rocky bottoms, wrecks, and kelp forests.^[1]^[2] Juveniles are pelagic and spend their first 2-3 years near the coast in shallow waters, growing to about 17 cm in the first year before migrating deeper as they mature, often forming small shoals or occurring solitarily in open sea environments.^[1]^[2] Pollack are carnivorous predators with a trophic level of 4.3, feeding primarily on small fish such as herring (Clupea harengus), sandeels (Ammodytes tobianus), sprat (Sprattus sprattus), and capelin (Mallotus villosus), as well as deep-sea prawns, hunting either individually or in groups near the seabed.^[1]^[2] Reproduction is oviparous and gonochoristic, with spawning occurring in shoals from January to April (peaking in March) at depths up to 100 m, after which eggs and larvae drift to coastal nursery areas; the species is oceanodromous, undertaking migrations for spawning.^[1]^[2] Ecologically, pollack play a role in marine food webs as both predators and prey, and they support small-scale commercial fisheries and recreational angling due to their good-flavored flesh, though they are often caught incidentally with cod (Gadus morhua).^[1]^[2] It was assessed as Least Concern by the IUCN in 2013, though recent stock assessments indicate declining populations in some areas due to fishing pressure, leading to advice for zero commercial catch in 2025 in regions such as the Celtic Seas.^[1]^[4]

Taxonomy

Classification

Pollachius pollachius belongs to the kingdom Animalia, phylum Chordata, class Actinopterygii, order Gadiformes, family Gadidae, genus Pollachius, and species pollachius.^[5] This hierarchical classification places it among the ray-finned fishes, specifically within the cod-like gadiforms, a group characterized by their elongate bodies and adaptations to marine environments.^[6] The species was first described by Carl Linnaeus in 1758 as Gadus pollachius in the tenth edition of Systema Naturae, volume 1, page 254.^[7] It was later reclassified into the genus Pollachius, established by Sven Nilsson in 1832 in his Prodromus ichthyologiae Scandinavicae, to better reflect its distinct morphological traits within the Gadidae family.^[8] Within the Gadidae family, P. pollachius is closely related to other gadids such as the Atlantic cod (Gadus morhua) and the saithe (Pollachius virens), sharing ecological niches in the North Atlantic where juveniles often school together.^[6] The genus Pollachius is distinguished from Gadus by features including a protruding lower jaw and the absence of a chin barbel.^[6]

Etymology and nomenclature

The scientific name Pollachius pollachius originates from the work of Carl Linnaeus, who first described the species as Gadus pollachius in his 1758 Systema Naturae.^[9] The genus Pollachius was later established, with the current binomial reflecting its placement within the cod family Gadidae.^[6] The genus name derives from Scottish dialect terms such as "podlock" or "paddle," denoting a type of bumpfish.^[6] The specific epithet pollachius is a Latinized form of the same root, creating a tautonym.^[6] Common names for P. pollachius vary regionally, including "pollack" in English (preferred by the FAO), "lieu jaune" in French, and "abadejo" in Spanish.^[10] The English name "pollack" (or variant "pollock") traces to Middle English "poullok," possibly derived from Scottish Gaelic "pollag" or Irish "pollóg," with roots in earlier Scots "podlok."^[11]^[12] Historical synonyms include Gadus lycostomus (Faber, 1828), Merlangus poilachius (Fleming, 1828), Pollachius typus (Bonnaparte, 1846), Gadus viridis (Gronow, 1854), and Pollachius carbonarius (Risso, 1826).^[9] Naming confusions have arisen with the closely related Pollachius virens, as both species share the common name "pollock" in North American usage, leading to occasional misidentification in early literature.^[13]

Physical description

Morphology

Pollachius pollachius exhibits a fusiform body shape with a circular cross-section, which supports its active swimming lifestyle in coastal and offshore waters. The head features a relatively large terminal mouth, where the lower jaw protrudes beyond the upper jaw, and lacks a chin barbel, distinguishing it from related gadoid species. The lateral line is dark and prominent, arching sharply over the pectoral fin base before continuing straight along the body.^[14]^[9] The fin configuration includes three dorsal fins with no spines and a total of 29–33 soft rays, and two anal fins with a total of 27–30 soft rays. The pectoral fins are long and pointed, aiding in maneuverability, while the caudal fin is forked. The species has 52-55 vertebrae, contributing to its elongated form.^[14]^[15] Individuals of P. pollachius can attain a maximum reported total length of 130 cm TL and a maximum weight of 18.1 kg, though common lengths are around 75 cm TL. These dimensions reflect the species' potential for substantial growth within the Gadidae family.^[14]^[9]

Coloration and variations

The body of Pollachius pollachius exhibits a distinctive coloration that transitions sharply from the dorsal surface to the ventral side. The dorsal surface is typically dark greenish-brown to black, providing a stark contrast to the silver-gray sides and white ventral area.^[6]^[16] A dark lateral line runs along the body, often bending sharply around the pectoral fin, while the upper portion of the body features yellow to orange streaks or blotches, and the pelvic fins may show a yellowish tint.^[6]^[16] Coloration in P. pollachius shows intraspecific variations influenced by age, size, and habitat. Juveniles are generally paler, displaying green, brown, or occasionally crimson and gold hues with more pronounced spotting, which helps them remain inconspicuous in coastal environments.^[2] In contrast, adults tend to darken overall, with larger and older individuals appearing more intensely brown or greenish on the back, potentially as an adaptation to deeper or more exposed habitats.^[2] These variations are not fixed but can adjust subtly based on surrounding conditions, such as rocky substrates or water depth.^[6]^[16] The mottled patterns and gradient coloration of P. pollachius serve a key role in camouflage, allowing the species to blend with rocky substrates, kelp beds, and algal cover in their preferred habitats.^[2] This adaptation is particularly evident in juveniles, whose spotted and variable tones mimic the irregular textures of nearshore rocks and seaweed, reducing visibility to predators during early life stages.^[2] In adults, the dark dorsal tones and lateral streaks further enhance integration with deeper, shadowed reef environments.^[6]

Distribution and habitat

Geographic range

Pollachius pollachius is native to the Northeast Atlantic Ocean, with its primary distribution extending from Iceland and the Faroe Islands southward to the Bay of Biscay along the coasts of Spain and France, and eastward to the southern Baltic Sea, including records from Poland, Latvia, and Estonia.^[6]^[17] The species' latitudinal range spans from 72°N to 36°N, while its longitudinal extent covers 25°W to 28°E.^[6] Although primarily distributed in the eastern Atlantic, occasional records of P. pollachius have been documented in the northwest Atlantic off the coasts of Canada, indicating vagrant occurrences rather than established populations.^[17] The species has no confirmed presence in the Pacific Ocean or the Southern Hemisphere.^[6]

Habitat preferences

Pollachius pollachius is a benthopelagic and oceanodromous species primarily inhabiting marine environments associated with hard bottom substrates. It prefers structured habitats such as rocks, reefs, shipwrecks, and oil platforms, while avoiding soft sediments. The species is typically found at depths of 40–200 m, with a common range of 40–100 m.^[6]^[2] Juveniles exhibit pelagic behavior in coastal waters during their first 2–3 years, favoring rocky areas, kelp beds, sandy shores, and estuaries. By age 3, they transition to depths of 40–100 m. Adults occupy both inshore and offshore regions, often occurring singly or in small shoals within these structured environments.^[6]^[2]^[16] The species tolerates temperatures ranging from 7–11.9°C, with a mean of 8.9°C, though juveniles show optimal growth between 9–15°C. P. pollachius is fully marine, preferring salinities around 35 ppt.^[6]^[18]

Life history

Growth and development

Pollachius pollachius exhibits a lifespan of up to 8 years, with individuals reaching sexual maturity at approximately 41 cm in total length (TL), typically between ages 3 and 4, though the range can extend to 42 cm or more.^[6] Growth is relatively rapid in early life, with first-year juveniles attaining lengths of around 17 cm TL, increasing to up to 40 cm TL by age 3.^[6] The common adult length is 75 cm TL, with a maximum recorded size of 130 cm TL.^[6] There is no significant sexual dimorphism in size attainment throughout ontogeny.^[6] Early development begins with pelagic eggs and larvae that remain in the water column for several weeks to months before post-larvae settle into coastal benthic habitats.^[6] Juveniles are primarily pelagic and associated with nearshore coastal areas for the first 2-3 years, gradually shifting to deeper offshore waters (40-100 m) as they mature and grow larger.^[6]^[19] This ontogenetic habitat transition aligns with increasing body size and changing ecological roles, though juveniles may briefly utilize shallow coastal zones before deeper migration.^[19]

Reproduction

Pollachius pollachius is oviparous and gonochoristic, with external fertilization and no parental care.^[20] Spawning occurs from January to April for females and extends to May for males, with peak activity typically in February to March depending on the region.^[21] This process takes place primarily at depths up to 100 m, often in offshore areas with hard bottoms.^[22] The species exhibits high fecundity, with females producing approximately 600,000 eggs per kilogram of body weight over multiple batches.^[23] Eggs are pelagic, buoyant, and released into open water where they drift toward coastal nurseries.^[24] Larvae are planktonic upon hatching, remaining in the water column before settling into coastal habitats such as rocky areas and kelp beds after several weeks.^[1] Pollack are batch spawners, with females typically releasing around five batches per season under optimal conditions like water temperatures of 8–10 °C.^[23] Sexual maturity is reached at lengths of 42–50 cm for females and slightly smaller sizes for males, around 36–41 cm, with regional variations (e.g., 47.1 cm for females and 36.1 cm for males on the Galician shelf).^[21]^[1] During spawning, adults form dense aggregations on dedicated grounds, and individuals may undertake migrations to deeper offshore sites to participate.^[1] These behaviors facilitate gene flow across populations but vary by location, with asynchronous gonadal development allowing prolonged reproductive periods.^[21]

Ecology

Diet and feeding behavior

Pollachius pollachius is a carnivorous piscivore occupying a trophic level of 4.3 based on diet studies.^[25] Adults primarily prey on schooling fish including herring (Clupea harengus), sandeels (Ammodytes tobianus), sprat (Sprattus sprattus), and capelin (Mallotus villosus), as well as invertebrates such as deep-sea prawns (Pandalus borealis).^[2]^[26] Juveniles feed predominantly on crustaceans, including mysid shrimps and decapod larvae, with a shift toward fish as they mature.^[2]^[27] The species employs an ambush feeding strategy, often positioning itself close to the seabed or within structures like kelp forests and wrecks before darting upward to capture passing prey.^[2]^[28] This behavior occurs solitarily or in small groups around reef-like habitats that facilitate foraging.^[2] Feeding intensity and diet composition exhibit seasonal variations, with higher consumption rates and a greater reliance on pelagic crustaceans and fish in summer compared to winter, when benthic polychaetes become more prominent.^[27] Juvenile Pollachius pollachius often form schools in coastal pelagic zones, particularly in shallow inshore waters where they associate with other gadoid species such as saithe (Pollachius virens).^[6]^[29] In contrast, adults are typically solitary or occur in small, loose shoals, though they aggregate into denser groups during spawning at specific offshore sites.^[6] P. pollachius possesses generalist hearing capabilities, enabling detection of underwater sounds, and individuals produce grunt-like vocalizations, with juveniles emitting short grunts during social encounters.^[6] They are also visual predators adapted to low-light conditions in their preferred habitats, featuring violet/blue-sensitive cones that undergo spectral absorbance shifts to enhance vision in dimly lit coastal environments.^[30] Pollack display diurnal activity patterns, with heightened movement and interaction during daylight hours.^[31] They show a strong affinity for structural cover, frequently associating with underwater features like shipwrecks, rocky reefs, and oil platforms while avoiding open water.^[6]^[32] No territorial behavior is observed in adults, and oceanodromous migrations are indicated for both feeding and spawning purposes based on tagging studies.^[33]

Fisheries and conservation

Commercial fisheries

Pollachius pollachius is primarily exploited as bycatch in commercial fisheries targeting cod (Gadus morhua) and saithe (Pollachius virens), though targeted fisheries employ gillnets, longlines, traps, and handlines in certain regions. In the Bay of Biscay and Iberian waters, it is caught mainly by nets and lines in French fleets, gillnets and longlines in Spanish operations, and polyvalent gear in Portuguese fisheries. The species is also popular in recreational angling, particularly in coastal areas of the Northeast Atlantic, where handlines are commonly used.^[1]^[34]^[22] Global capture production of P. pollachius has fluctuated between 0 and 20,000 tonnes annually from 1980 to 2023, with the majority occurring in the Northeast Atlantic. Key production areas include the Bay of Biscay (ICES Subarea 8 and Division 9.a) and the Celtic Sea (Subareas 6–7), where landings are dominated by small-scale and mixed demersal fisheries. In Subareas 6–7, catches are distributed across otter trawlers (23%), static nets (44%), and other gears (33%).^[9]^[22] The flesh of pollack is noted for being dry yet flavorful, lending itself to uses as fresh, smoked, or dried product; however, the species supports only a small dedicated fishery and is frequently landed in mixtures with cod. Historical trends indicate overall stability in global production, though regional declines have occurred, such as in the Celtic Seas where landings fell from 6,257 tonnes in Subarea 7 in 1980 to 2,828 tonnes in 2018. Estimated catches in Subareas 6–7 reached approximately 2,144 tonnes in 2024, reflecting continued low-level exploitation amid mixed fisheries.^[1]^[35]

Conservation status and management

Pollachius pollachius is classified as Least Concern on the IUCN Red List, with the assessment originally conducted in 2013 and no subsequent global reassessment indicating a change in status as of 2025. However, regional populations face concerns, particularly in the Celtic Seas and Bay of Biscay, where overfishing has led to stock declines below sustainable levels.^[36] Recent reports from 2023 to 2025 highlight notable decreases in abundance around the Isle of Man and in the UK southwest, attributed to intensified fishing pressure.^[27] Key threats to the species include bycatch mortality in mixed demersal fisheries and habitat degradation caused by bottom trawling, which damages rocky substrates preferred by pollack.^[37] These impacts are exacerbated in areas with high fishing activity, contributing to reduced recruitment and population resilience.^[38] Management efforts involve International Council for the Exploration of the Sea (ICES) recommendations for zero catch in Celtic Seas subareas 6–7 for 2025 to allow stock recovery; however, the EU set a bycatch total allowable catch (TAC) of 959 tonnes for 2025 in relevant subareas (e.g., 8abde), and TACs have historically been set above advice and sometimes exceeded in EU-regulated areas.^[39]^[40] EU quotas aim to control commercial exploitation, supplemented by Marine Protected Areas that safeguard wreck and rocky habitats critical for the species.^[41] Monitoring remains challenging due to the species' affinity for complex, rocky environments that hinder survey efforts.^[22] Recreational fishing regulations, including voluntary bag limits in the UK southwest, further support conservation.^[42] The ICES 2025 benchmarks resulted in an improved age-structured analytical stock assessment through enhanced data integration. Consequently, ICES advised that total removals in 2026 should be no more than 3,310 tonnes when applying the maximum sustainable yield approach, informing recovery strategies and aiming to stabilize populations across its range.^[43]^[36]
