Red snapper
The red snapper (Lutjanus campechanus) is a deep-bodied marine fish belonging to the family Lutjanidae, distinguished by its rosy-red to dark pink coloration that fades to a pale underbelly, red eyes, pointed dorsal and anal fins, and a sharp-edged tail, with juveniles often featuring a dark spot on their sides.[1][2][3] Adults typically measure 24 inches (60 cm) in length and weigh 2–10 pounds (0.9–4.5 kg), though they can reach up to 40 inches (100 cm) and 50 pounds (23 kg).[1][2] This species inhabits the continental shelf, where juveniles occupy shallow, sandy or muddy bottoms, while adults prefer hard structures such as reefs, ledges, rocky banks, and artificial reefs like oil platforms at depths of 30–200 feet (9–61 m), occasionally up to 620 feet (189 m).[1][2][3] It is primarily distributed throughout the Gulf of Mexico, along the southeastern U.S. Atlantic coast from North Carolina to Florida, and sporadically in the western Atlantic from Massachusetts to Brazil, though it is rare north of the Carolinas.[1][2] Biologically, red snapper are long-lived predators with a lifespan exceeding 50 years, reaching sexual maturity between 2 and 5 years old, typically at 12–16 inches (30–40 cm) in length.[1][2][4] They spawn from May to October, peaking from June to August in most areas, with females capable of releasing 1–3 million eggs per batch, totaling up to 10–20 million eggs over the season in multiple batches every 4–5 days, feeding primarily on crustaceans like crabs and shrimp, as well as smaller fish.[1][2][5] Growth is rapid in early years, reaching about 8 inches (20 cm) in the first year and adding 3–4 inches (8–10 cm) annually thereafter before slowing.[3][6] Red snapper support one of the most valuable fisheries in U.S. waters, with commercial landings of approximately 8.3 million pounds (3.8 million kg) in 2023 and significant recreational harvest, primarily using hook-and-line, longlines, and trawls; populations were overfished historically but the Gulf stock has since rebuilt and is no longer overfished, though recent assessments indicate the stock is rebuilding successfully, with catch limits increasing to support sustainable harvest, and strict quotas and seasonal closures continue to be managed by NOAA Fisheries.[1][2] Their firm, white flesh is prized for culinary use, including as a delicacy in throats and cheeks, making them a highly sought-after species for both markets and sport fishing.[3][2]Taxonomy and identification
Taxonomy
The red snapper is scientifically classified as Lutjanus campechanus (Poey, 1860), a species within the family Lutjanidae, which encompasses the snappers, a group of perciform fishes primarily inhabiting tropical and subtropical marine environments.[1][7] The genus Lutjanus, to which the red snapper belongs, includes approximately 67 species distributed worldwide in coastal and reef-associated habitats.[8] Members of this genus are distinguished by their moderately large mouths equipped with prominent, enlarged canine teeth in both jaws, alongside smaller villiform teeth, features that aid in capturing prey and set them apart from other lutjanid genera.[9][10] Historically, the red snapper has been known under several synonyms, reflecting taxonomic revisions and spelling variations over time, including Lutjanus blackfordii Goode & Bean, 1878, and the original binomial Mesoprion campechanus Poey, 1860.[11][12] The genus name Lutjanus originates from the Malay term "ikan lutjan," referring to a local name for snapper-like fishes.[7] The specific epithet "campechanus" derives from the Campeche Bank in the Gulf of Mexico, the type locality designated by Felipe Poey in his original description based on specimens collected there.[2]Physical characteristics
The red snapper (Lutjanus campechanus) possesses an elongated, compressed body that is moderately deep, featuring a distinctive sloped forehead and a large terminal mouth suited for its predatory lifestyle.[2][13] This body form aids in maneuvering through reef environments, with the head profile contributing to its streamlined appearance. The jaws are equipped with prominent canine teeth at the front, alongside densely packed villiform (hair-like) teeth, enabling it to capture and hold prey effectively.[2][14] Coloration is characteristically pinkish-red over the back and upper sides, fading to a white or rosy belly, with dark red eyes that enhance its visual identification.[15][16] The fins are predominantly red, often with darker edges, while juveniles display a prominent black spot below the anterior part of the soft dorsal fin on their upper sides, which fades as the fish matures.[16][17] The dorsal fin typically includes 10 to 11 spines followed by 13 to 14 soft rays, and the anal fin has 3 spines and 8 soft rays, both tapering to points near the caudal fin.[2][18] Adults commonly reach 60 cm in total length, though maximum sizes recorded are up to 100 cm in length and 20 to 23 kg in weight.[19][18] Growth is rapid during the first few years, allowing juveniles to quickly attain sizes that reduce predation risk, before slowing asymptotically. This pattern is well-described by the von Bertalanffy growth model, with parameters of L∞ ≈ 94 cm, K ≈ 0.18 year−1, and t0 ≈ −0.55 years (for all specimens), indicating a theoretical maximum length approached over time and an initial growth phase offset from birth.[20]Distribution and habitat
Geographic range
The red snapper (Lutjanus campechanus) is distributed across the western Atlantic Ocean, with its primary range encompassing the Gulf of Mexico, the Caribbean Sea, and the coastal waters of North, Central, and northern South America. This species occurs from the coasts of Brazil northward along the eastern seaboard of the United States to Massachusetts, though it becomes increasingly rare north of the Carolinas.[21][1] The core populations are concentrated in the northern Gulf of Mexico, which supports approximately 90% of the U.S. commercial and recreational catch, and the Campeche Bank off the Yucatán Peninsula in Mexico, where significant abundances persist despite historical declines in catches.[1][22] Following strong recruitment events in the late 1980s and 1990s, associated with improved management and environmental conditions, the species has exhibited northward range expansion, with increased sightings and captures along the U.S. Atlantic coast beyond its traditional limits.[23][24] Red snapper exhibit ontogenetic habitat shifts and seasonal movements influenced by water temperature. Juveniles typically settle in nearshore, shallow waters shortly after larval stages, while adults migrate to deeper shelf areas as they mature. These fish undertake seasonal migrations, moving offshore in winter to avoid cooler temperatures and returning inshore during warmer months to aggregate near reef structures.[21][25][1]Habitat requirements
Red snapper (Lutjanus campechanus) exhibit distinct habitat preferences that vary across life stages, reflecting ontogenetic shifts from inshore nursery areas to offshore environments. Juveniles primarily settle in shallow coastal waters, typically at depths of 5-30 meters, over sandy or muddy bottoms in estuaries, bays, seagrass beds, and nearshore areas.[1][26] These habitats provide shelter from predators and abundant food resources for early development, with post-larvae transitioning from pelagic to benthic life in these low-relief substrates.[27] As red snapper mature into adults, they migrate to deeper waters on the continental shelf, occupying depths of 30-200 meters near hard structures such as natural reefs, ledges, rock outcrops, oil platforms, and artificial reefs.[1][26] These structured habitats in the Gulf of Mexico and western Atlantic support larger body sizes and reproductive activities, with adults associating closely with irregular bottoms that enhance foraging opportunities. Artificial reefs have notably expanded available habitat, increasing density in otherwise unstructured areas.[28] Optimal environmental conditions for red snapper include water temperatures of 13-30°C, with avoidance of colder waters below 10°C that can limit distribution and survival.[26] They thrive in full marine salinities of 33-37 ppt, reflecting their preference for oceanic conditions rather than brackish environments.[26] These parameters align with their primary distribution in the Gulf of Mexico, where seasonal temperature fluctuations influence habitat occupancy.[1] This ontogenetic progression—from shallow, soft-bottom nurseries for juveniles to deeper, structured shelf habitats for adults—facilitates growth and reduces competition, with fish typically shifting offshore by age 1-2 as they exceed 200-250 mm in length.[1][27]Biology and ecology
Reproduction and life cycle
Red snapper (Lutjanus campechanus) reach sexual maturity at varying ages depending on sex and environmental factors, with males typically maturing earlier than females. Females generally attain maturity between 3 and 5 years of age, at lengths of 30-40 cm total length, while males may mature by age 2 at similar or slightly smaller sizes.[1][29] Once mature, red snapper engage in batch spawning, releasing multiple batches of eggs over the season, which spans from May to October in the Gulf of Mexico, with peak activity occurring between June and August.[1][5] Spawning occurs in offshore aggregations over reefs and structures, where females release 1.5-2.5 million eggs per batch, with larger individuals producing toward the higher end of this range.[4] These eggs are pelagic and buoyant, hatching into larvae within 24-36 hours. The resulting larvae remain in the water column for a pelagic duration of 20-40 days, during which they are transported by ocean currents before undergoing post-larval settlement in shallower coastal areas, such as bays or nearshore habitats with sandy or muddy bottoms.[30][1] The life cycle of red snapper includes distinct developmental stages: the brief egg phase, extended larval period vulnerable to predation and environmental conditions, settlement into juvenile habitats, and growth to adulthood over reefs. Recruitment success, or the survival of larvae to juvenile stages, exhibits high variability influenced by ocean currents that affect larval dispersal and by predation pressures on early life stages.[1] Adults can live up to 50 years, contributing to multiple spawning seasons and supporting population resilience despite recruitment fluctuations.[1][30]Diet and behavior
The red snapper (Lutjanus campechanus) is an opportunistic carnivore whose diet varies ontogenetically. Juveniles primarily consume crustaceans such as shrimp (Sicyonia spp.) and crabs (Portunus gibbesii), along with smaller fish and zooplankton.[31][32] Adults shift to a more diverse array of prey, including fish like menhaden and anchovies, squid (Loligo spp.), and gastropods, reflecting their access to reef-associated resources.[31][32] As ambush predators, red snappers utilize reef structures for cover to surprise prey, often positioning themselves above or near benthic habitats.[31] Their feeding activity is continuous but peaks at dusk and dawn, with nocturnal periods showing increased consumption of sand- or mud-associated organisms, suggesting possible diel migrations away from reefs.[31] Predators play a key role in red snapper ecology, particularly during early life stages. Juveniles are vulnerable to seabirds and larger reef fish such as groupers, jacks, barracudas, and moray eels, which share shallow habitats.[1] Adults face threats primarily from sharks and large marine mammals that target larger individuals in deeper waters.[1] Social behavior in red snappers changes with age and size. Juveniles form schools around artificial and natural reefs for protection and foraging efficiency during their structural dependency phase.[33] In contrast, adults exhibit territorial tendencies, defending specific reef sites with limited movement.[17] They communicate via sound production, generating drumming or croaking noises with the swim bladder, potentially for territorial signaling or coordination.[34] Red snappers possess sensory adaptations suited to their reef environment, including forward-facing eyes that provide a wide field of vision for detecting movement in low-light conditions.[35] Their lateral line system, with a high ratio of scales to vertebrae (2:1 to 3:1), enables precise detection of hydrodynamic vibrations from prey or conspecifics, supporting both hunting and schooling behaviors.[36] These traits enhance their ambush strategy in association with reefs.[31]Fisheries and human use
Commercial exploitation
The commercial red snapper fishery in the U.S. Gulf of Mexico originated in the late 19th century, with a rapid expansion beginning in the 1880s around ports like Pensacola, Florida, driven by increasing demand for the species in domestic markets. Landings grew substantially in the early 1900s, reaching a historical peak of approximately 14 million pounds in 1902, before declining due to overexploitation and shifts in fishing effort. By the mid-20th century, commercial harvests stabilized around 7-10 million pounds annually in the 1960s, but fell to 2-5 million pounds during the 1990s amid stock declines and regulatory caps. As of 2023, U.S. Gulf commercial landings have averaged approximately 7-8 million pounds annually, reflecting quota-based management and stock recovery efforts.[37][38][39][40] Commercial fishers primarily employ vertical line gear, such as handlines and electric reels (often involving vertical jigging for targeted efficiency), along with bottom longlines to harvest red snapper from reef habitats. Trawls, particularly in the shrimp fishery, contribute through bycatch, though directed snapper trawling is limited. These methods allow for selective harvesting at depths of 100-300 feet, but longlines are associated with bycatch of protected species, including sea turtles and sharks, prompting ongoing gear modifications like circle hooks to reduce interactions.[1][41] The U.S. Gulf red snapper commercial fishery generates an ex-vessel value of approximately $40-50 million annually as of 2023, supporting around 300-400 vessels and contributing to broader reef fish industry revenues exceeding $100 million. Landed fish are often exported to markets in Europe and Asia, where demand for premium snapper fillets drives international trade, though domestic consumption remains dominant. Bycatch mitigation remains a key challenge, with interactions costing the industry time and resources while affecting endangered species populations.[42][43][44] In markets, red snapper is sold primarily as fresh or frozen fillets, whole gutted fish, or headed-and-gutted products, with fillets commanding premium prices due to their mild flavor and firm texture. Mislabeling issues have plagued the supply chain, with studies finding up to 79% of red snapper samples mislabeled in some urban markets like New York City, including substitutions with tilefish, known for elevated mercury levels, eroding consumer trust and prompting DNA-based verification programs.[45] Globally, the U.S. Gulf accounts for the majority of commercial red snapper production and trade, with minor contributions from Mexican waters in the southern Gulf and limited harvests in the Caribbean, where smaller-scale operations supply regional markets. U.S. exports focus on high-value frozen products, while imports from Mexico occasionally supplement domestic supply.[1]Recreational fishing
Red snapper (Lutjanus campechanus) is one of the most sought-after species for recreational anglers in the Gulf of Mexico, drawing millions of participants annually due to its fighting spirit, culinary value, and abundance around offshore structures. Recreational fishing for red snapper accounts for millions of trips annually in the Gulf of Mexico, representing a significant portion of saltwater angling effort. Recent recreational landings have exceeded 10 million pounds annually in some years, supporting ongoing management adjustments. Charter boats are central to this pursuit, enabling access to federal waters for private anglers and contributing to the fishery's accessibility and cultural appeal.[46][1] Common techniques for catching red snapper emphasize bottom fishing with hook-and-line setups, where anglers deploy baited rigs to depths of 60–200 feet near artificial reefs, shipwrecks, and oil rigs—prime hotspots that concentrate the fish. Popular baits include live or cut cigar minnows, squid strips, and pilchards threaded onto circle hooks (typically 7/0 to 9/0) with 8–16 ounce sinkers to combat strong currents. Trolling with diving plugs or live-bait rigs at 4–8 knots is also effective for larger specimens in open water, while vertical jigging with heavy metal jigs tipped with soft plastics appeals to those seeking a more active approach. These methods overlap somewhat with commercial practices but are adapted for sport, focusing on individual or small-group angling rather than large-scale harvesting.[47][48][49] Seasons for recreational red snapper fishing are quota-driven and vary by state waters versus federal waters, generally opening in late spring (e.g., May–June) and extending through summer weekends or specific blocks to prevent overharvest, with 2025 federal for-hire seasons spanning up to 107 days. Dominant gear includes 6–7 foot medium-heavy to heavy action rods paired with conventional or spinning reels spooled with 20–50 lb braided line and fluorocarbon leaders, designed to handle typical catches of 10–20 lb fish while minimizing release mortality through circle hooks and descending devices. State-specific openings, such as Florida's multi-week periods from May to September, further extend opportunities for private anglers.[50][51] Tournaments underscore the sport's competitive and communal aspects, with longstanding events like the Alabama Deep Sea Fishing Rodeo—established in 1929 and billed as the world's largest directed fishing tournament—featuring red snapper categories that draw thousands of entrants to Dauphin Island each July, fostering traditions and boosting local engagement.[52] Economically, recreational red snapper angling drives substantial tourism revenue for Gulf states, supporting a multi-billion dollar industry through expenditures on charters, fuel, lodging, and equipment that sustain jobs and coastal economies. In Texas, for instance, the annual value of red snapper trips alone exceeds $200 million, including producer surplus for charter operations and consumer surplus for anglers.[53][54]Management and conservation
Regulations and quotas
In the United States, the red snapper fishery is governed by the Magnuson-Stevens Fishery Conservation and Management Act, with the Gulf of Mexico Fishery Management Council overseeing management in the Gulf of Mexico and the South Atlantic Fishery Management Council handling the Atlantic region off the southeastern states.[55][56] For 2025, the acceptable biological catch (ABC) for the Gulf stock is 16.31 million pounds whole weight, reflecting stock recovery under the ongoing rebuilding plan.[57] The total annual catch limit (ACL) matches the ABC at 16.31 million pounds, apportioned 51% to the commercial quota (8.32 million pounds) and 49% to the recreational quota (7.99 million pounds).[57] The recreational quota is subdivided into a private angling component (57.7%, or 4.61 million pounds) and a federal for-hire component (42.3%, or 3.38 million pounds), allowing targeted monitoring and sector-specific adjustments.[50] In the Gulf, the 2025 federal for-hire recreational season opens June 1 and closes September 16, while private recreational seasons in federal waters are allocated to states and vary accordingly—for instance, Florida's allocation supports a 126-day season starting May 24, Texas runs from June 1 to November 21, and Louisiana opens May 1 with a four-fish bag limit. As of November 2025, the Louisiana private recreational season closed on November 16 upon reaching its quota after 200 days, Texas closes on November 21, and Florida's season remains open with planned dates extending into December.[58][59][60][61] In the South Atlantic, recreational fishing is highly restricted due to overfishing concerns, with the federal season limited to July 11-12, 2025.[51] Standard regulations include a 16-inch total length minimum size limit for both commercial and recreational harvest, alongside a two-fish-per-person daily bag limit for recreational anglers in the Gulf.[62] Exempted Fishing Permits (EFPs) are issued by NOAA Fisheries to support research, data collection, and innovative management approaches, such as state-level recreational allocations in the Gulf.[63] Internationally, red snapper management involves national frameworks in Mexico and Cuba, with U.S.-Mexico coordination through the Binational Red Snapper Technical Working Group to address transboundary stock dynamics, though specific quotas remain under each country's jurisdiction.[64]Conservation efforts
The red snapper (Lutjanus campechanus) populations in U.S. waters, particularly in the Gulf of Mexico, have historically been overfished due to intense exploitation from the mid-20th century through the early 2000s, leading to depleted stocks and delayed recovery. The Gulf stock was classified as not overfished or undergoing overfishing based on the 2023 SEDAR 74 assessment, with ongoing monitoring through SEDAR 98, though it remains under a rebuilding plan aimed at achieving target biomass levels by 2032. In the South Atlantic, the stock was deemed overfished until the SEDAR 73 Update Assessment indicated it is no longer overfished but continues rebuilding toward full recovery by 2044. These populations exhibit moderate to high vulnerability to fishing pressure, scored at 54 out of 100, largely attributable to the species' slow growth after age 8–10, late full maturity around 10 years, and longevity up to 50 years. Key threats to red snapper include persistent bycatch in non-selective fisheries such as shrimp trawling, which historically accounted for significant juvenile mortality, and habitat degradation from events like the 2010 Deepwater Horizon oil spill. The spill released over 200 million gallons of crude oil into the Gulf, causing sublethal effects on red snapper larvae, including reduced body condition and altered diets in juveniles and adults, as well as liver damage observed in sampled fish years later. Overfishing prior to stricter controls in the 2000s exacerbated these pressures by reducing spawning stock biomass and impairing recruitment. Conservation efforts have focused on reducing harvest pressure and enhancing habitat to support recovery. The Individual Fishing Quota (IFQ) system, implemented by NOAA Fisheries in 2007 for the Gulf commercial sector, allocates shares of the annual catch limit to permit holders, eliminating derby-style fishing and reducing overcapacity while promoting sustainability. Marine protected areas, such as the Oculina Habitat Area of Particular Concern established in 1984 and expanded in subsequent years, prohibit bottom fishing to safeguard snapper-grouper habitats and spawning aggregations. Regular stock assessments via the SEDAR process provide data-driven updates on biomass and fishing mortality, informing adaptive management. State-led artificial reef programs, including deployments of decommissioned oil rigs and concrete structures in the Gulf and South Atlantic, have created essential hard-bottom habitats that boost juvenile recruitment and adult densities, with surveys showing enhanced red snapper abundance around these sites. Ongoing monitoring employs advanced techniques to track population dynamics and inform conservation. Acoustic telemetry tagging has been used to study movement patterns, site fidelity, and release mortality, revealing ontogenetic shifts from shallow to deeper reefs as fish mature and aiding estimates of discard survival rates. Genetic studies, utilizing microsatellite loci and genomic analyses, have identified fine-scale heterogeneity in recruitment cohorts across the Gulf, helping quantify larval connectivity and effective population sizes without evidence of strong sweepstakes effects. In 2025, South Atlantic rebuilding progress was bolstered by Amendment 59, which adjusted catch limits based on the latest assessment to prevent overfishing while allowing controlled harvest. Emerging challenges include climate change, which poses risks to early life stages through elevated sea temperatures that reduce larval survival by up to 68% in experimental conditions mimicking future warming scenarios. Such impacts could hinder recruitment by altering growth rates and increasing vulnerability to predation and dispersal limitations.Culinary aspects
Preparation and cuisine
Red snapper is prized in culinary traditions for its mild, slightly sweet flavor and firm, lean white flesh with low oil content, which allows it to absorb seasonings without becoming greasy.[65][66] This versatile texture makes it suitable for a range of cooking methods, including grilling, baking, frying, and raw preparations like ceviche or sashimi. In Gulf Coast cuisine, where red snapper has been a staple since the mid-19th century following the establishment of commercial fisheries around 1845, it features prominently in both home cooking and communal dishes such as seafood boils.[67][68] Traditional preparations often highlight regional influences. In Louisiana Creole cooking, red snapper is commonly baked with a tomato-based sauce, incorporating onions, bell peppers, celery, and spices to create a flavorful Creole topping that enhances the fish's natural sweetness.[69] A classic example is red snapper court-bouillon, a roux-thickened stew originating from French poaching techniques adapted in Cajun and Creole kitchens, where fillets or whole fish are simmered in a reduced tomato broth with the "holy trinity" of vegetables for a hearty, piquant dish.[70][71] Along the Gulf Coast, frying is a popular method, with fillets coated in cornmeal or seasoned flour and deep-fried until golden, often served as bites or in po'boys to showcase the crisp exterior and moist interior.[72] In Mexican cuisine, Veracruz-style red snapper (huachinango a la veracruzana) involves baking a whole fish topped with a briny sauce of tomatoes, olives, capers, jalapeños, and oregano, reflecting Spanish and indigenous influences.[73] Grilling is favored in Mediterranean-inspired approaches, such as Greek-style preparations where whole or filleted snapper is brushed with olive oil, lemon, garlic, and herbs before being charred over high heat.[74] Raw applications extend its global appeal. In Caribbean traditions, red snapper ceviche marinated in lime juice with jalapeños, cilantro, and onions "cooks" the firm flesh, resulting in a refreshing, citrusy dish.[75] Asian influences appear in sashimi preparations, where thin slices of fresh snapper are served with soy sauce, ginger, and wasabi to highlight its clean, nutty notes.[76] Whole fish presentations, like those in Veracruz or grilled Caribbean styles, preserve the skin's vibrancy and allow for even flavor infusion, while fillets offer convenience for quicker cooking in stews or pan-sears. Red snapper pairs well with light, crisp sides such as rice pilaf or steamed vegetables like asparagus and zucchini, which complement its subtle taste without overpowering it. For wines, an oaked Chardonnay enhances baked or grilled preparations, its buttery notes balancing the fish's leanness and acidity from lemon or tomato sauces.[77]Nutritional profile
Red snapper is a nutrient-dense seafood option, providing a lean source of high-quality protein with minimal carbohydrates and fats in a typical 100-gram serving of raw fish. This serving contains approximately 20.5 grams of protein, 1.3 grams of total fat (primarily unsaturated), 0 grams of carbohydrates, and 100 kilocalories. These macronutrients make it an efficient choice for muscle maintenance and satiety without contributing significant energy from non-protein sources. In terms of micronutrients, red snapper is particularly rich in omega-3 fatty acids, delivering around 0.25 grams per 100-gram serving, mainly in the form of DHA and EPA, which support cellular health.[78] It also provides substantial amounts of selenium (about 49 micrograms, meeting 89% of the daily value) and vitamin B12 (approximately 3 micrograms, covering 125% of the daily requirement), essential for thyroid function, antioxidant defense, and red blood cell formation, respectively. Additionally, mercury levels in red snapper are low at around 0.23 parts per million (mean value), classifying it as a safer seafood choice compared to higher-mercury species.[79] The nutritional profile of red snapper contributes to several health benefits, including support for cardiovascular health through its omega-3 content, which may help reduce inflammation and improve lipid profiles. Its high selenium and B12 levels further aid in combating oxidative stress and maintaining neurological function. As a zero-carb, low-fat protein source, it aligns well with low-carbohydrate dietary patterns aimed at blood sugar control.[80] Compared to fattier fish like salmon (which has about 13 grams of fat per 100 grams), red snapper is notably leaner, offering a milder flavor profile while delivering comparable protein. It shares similarities with cod in its low-fat, flaky texture but provides a sweeter taste and higher omega-3 levels. Consumers should note that, like all finfish, red snapper may pose a risk for individuals with fish allergies, potentially causing reactions ranging from mild to severe. Although its mercury content is low, pregnant women, nursing mothers, and young children are advised to follow general FDA guidelines limiting intake of any seafood to minimize cumulative exposure.[81]| Nutrient (per 100g raw serving) | Amount | % Daily Value* |
