40-519: The northern red snapper ( Lutjanus campechanus ) is a species of marine ray-finned fish , a snapper belonging to the family Lutjanidae . It is native to the western Atlantic Ocean , the Caribbean Sea , and the Gulf of Mexico , where it inhabits environments associated with reefs . This species is commercially important and is also sought-after as a game fish . The northern red snapper
80-459: A free-swimming larval stage. However other patterns of ontogeny exist, with one of the commonest being sequential hermaphroditism . In most cases this involves protogyny , fish starting life as females and converting to males at some stage, triggered by some internal or external factor. Protandry , where a fish converts from male to female, is much less common than protogyny. Most families use external rather than internal fertilization . Of
120-521: A line, they tend to be nibblers and pickers, and a soft touch is needed when trying to catch them. Because the older red snapper like structure, anglers use bottom fishing over reefs, wrecks, and oil rigs, and use line and supplies in the 50-lb class. Since the anglers have to both choose the right bait and present it correctly, they tend to use multiple hooked baits. Favorite baits include squid, whole medium-sized fish, and small strips of fish such as amberjack . Although many northern red snapper are caught on
160-479: A long time, restricted mostly by fishing limits intended to ensure a sustainable population. The first minimum size limit was introduced in 1984, after a 1981 report described quickly declining harvests (both commercial and recreational) From 1985 to 1990, the annual recreational catch of red snapper was about 1.5 million. From 1991 to 2005, the catch was substantially higher, varying from year to year from 2.5 to 4.0 million. When northern red snapper bite on
200-525: A major industry in the Gulf of Mexico, but permit restrictions and changes in the quota system for commercial snapper fishermen in the Gulf have made the fish less commercially available. Researchers estimate the bycatch of young red snapper, especially by shrimp trawlers, is a significant concern. Genetic studies have shown many fish sold as red snapper in the US are not actually L. campechanus, but other species in
240-503: A single fish was 32 km. A northern red snapper attains sexual maturity at two to five years old, and an adult snapper can live for more than 50 years. Research from 1999–2001 suggested the populations of red snapper off the coast of Texas reach maturity faster and at a smaller size than populations off of the Louisiana and Alabama coasts. Northern red snapper are a prized food fish, caught commercially, as well as recreationally. It
280-453: A spiny dorsal fin , and a laterally compressed body. Northern red snapper have short, sharp, needle-like teeth, but they lack the prominent upper canine teeth found on the mutton, dog, and mangrove snappers. They are rather large and are red in color. This snapper reaches maturity at a length of about 39 cm (15 in). The common adult length is 60 cm (24 in), but may reach 100 cm (39 in). The maximum published weight
320-742: A trait still present in Holostei ( bowfins and gars ). In some fish like the arapaima , the swim bladder has been modified for breathing air again, and in other lineages it have been completely lost. The teleosts have urinary and reproductive tracts that are fully separated, while the Chondrostei have common urogenital ducts, and partially connected ducts are found in Cladistia and Holostei. Ray-finned fishes have many different types of scales ; but all teleosts have leptoid scales . The outer part of these scales fan out with bony ridges, while
360-437: Is 50 lb, 4 oz (22.79 kg) and the oldest reported age is 57+ years. Coloration of the northern red snapper is light red, with more intense pigment on the back . It has 10 dorsal spines, 14 soft dorsal rays, three anal spines and eight to 9 anal soft rays. Juvenile fish (shorter than 30–35 cm) can also have a dark spot on their sides, below the anterior soft dorsal rays, which fades with age. The northern red snapper
400-651: Is a Vietnamese sour soup indigenous to the Mekong Delta region of Southern Vietnam (Central Vietnam also have their own canh chua). It is typically made with fish from the Mekong River Delta, pineapple , tomatoes (and sometimes also other vegetables such as đậu bắp or dọc mùng ), and bean sprouts , in a tamarind -flavored broth . It is garnished with the lemony-scented herb ngò gai ( Limnophila aromatica ), caramelized garlic , and chopped scallions , as well as other herbs, according to
440-587: Is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called lepidotrichia , as opposed to the bulkier, fleshy lobed fins of the sister class Sarcopterygii (lobe-finned fish). Resembling folding fans , the actinopterygian fins can easily change shape and wetted area , providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to

These values are for inputs of length in cm and result in weight in kg. Szedlmayer et al. reported length vs. age data for L. campechanus in a primarily artificial reef environment off the coast of Alabama, US: TL(age) = 1,025 (1 – e^( -0.15 age)), N=409, R = 0.96. For
520-545: Is divided into the infraclasses Holostei and Teleostei . During the Mesozoic ( Triassic , Jurassic , Cretaceous ) and Cenozoic the teleosts in particular diversified widely. As a result, 96% of living fish species are teleosts (40% of all fish species belong to the teleost subgroup Acanthomorpha ), while all other groups of actinopterygians represent depauperate lineages. The classification of ray-finned fishes can be summarized as follows: The cladogram below shows
560-678: Is found at a depth of 30 to 620 feet in the Gulf of Mexico, the Caribbean Sea, and the southeastern Atlantic coast of Mexico and the United States and much less commonly northward as far as Massachusetts. In Latin American Spanish , it is known as mero , huachinango , pargo , or chillo . This species commonly inhabits waters from 9–60 m (30–200 ft), but can be caught as deep as 90 m (300 ft) on occasion. They stay relatively close to
600-432: Is relatively rare and is found in about 6% of living teleost species; male care is far more common than female care. Male territoriality "preadapts" a species for evolving male parental care. There are a few examples of fish that self-fertilise. The mangrove rivulus is an amphibious, simultaneous hermaphrodite, producing both eggs and spawn and having internal fertilisation. This mode of reproduction may be related to
640-656: Is sometimes used in Vietnamese canh chua ("Sour soup"). Red snapper is the most commonly caught snapper in the continental US (almost 50% of the total catch), with similar species being more common elsewhere. They eat almost anything, but prefer small fish and crustaceans . They can be caught on both live and cut bait, and also take artificial lures, but with less vigor. They are commonly caught up to 4.5 kg (10 lb) and 510 mm (20 in) in length, but fish over 18 kg (40 lb) have been taken. Recreational fishing for northern red snapper has been popular for
680-506: The Cyprinidae (in goldfish and common carp as recently as 14 million years ago). Ray-finned fish vary in size and shape, in their feeding specializations, and in the number and arrangement of their ray-fins. In nearly all ray-finned fish, the sexes are separate, and in most species the females spawn eggs that are fertilized externally, typically with the male inseminating the eggs after they are laid. Development then proceeds with
720-592: The deep sea to subterranean waters to the highest mountain streams . Extant species can range in size from Paedocypris , at 8 mm (0.3 in); to the massive ocean sunfish , at 2,300 kg (5,070 lb); and to the giant oarfish , at 11 m (36 ft). The largest ever known ray-finned fish, the extinct Leedsichthys from the Jurassic , has been estimated to have grown to 16.5 m (54 ft). Ray-finned fishes occur in many variant forms. The main features of typical ray-finned fish are shown in
760-488: The oviparous teleosts, most (79%) do not provide parental care. Viviparity , ovoviviparity , or some form of parental care for eggs, whether by the male, the female, or both parents is seen in a significant fraction (21%) of the 422 teleost families; no care is likely the ancestral condition. The oldest case of viviparity in ray-finned fish is found in Middle Triassic species of † Saurichthys . Viviparity
800-663: The sister lineage of all other actinopterygians, the Acipenseriformes (sturgeons and paddlefishes) are the sister lineage of Neopterygii, and Holostei (bowfin and gars) are the sister lineage of teleosts. The Elopomorpha ( eels and tarpons ) appear to be the most basal teleosts. The earliest known fossil actinopterygian is Andreolepis hedei , dating back 420 million years ( Late Silurian ), remains of which have been found in Russia , Sweden , and Estonia . Crown group actinopterygians most likely originated near
840-999: The Devonian-Carboniferous boundary. The earliest fossil relatives of modern teleosts are from the Triassic period ( Prohalecites , Pholidophorus ), although it is suspected that teleosts originated already during the Paleozoic Era . The listing below is a summary of all extinct (indicated by a dagger , †) and living groups of Actinopterygii with their respective taxonomic rank .

#1732790927837880-609: The Gulf of Mexico Fishery Management Council estimated the commercial value of the red snapper fishery to be $ 129 million. While specific numbers on the economic impact of recreational red snapper fishing are not available, it is clear that the activity has a significant economic impact on coastal communities through tourism and fishing-related activities. [1] Since 1990, the total catch limit for northern red snapper has been divided into 49% for recreational fishermen and 51% for commercial. Commercially, they are caught on multiple-hook gear with electric reels. Fishing for red snapper has been

Except from the bichirs , which just like the lungs of lobe-finned fish have retained the ancestral condition of ventral budding from the foregut , the swim bladder in ray-finned fishes derives from a dorsal bud above the foregut. In early forms the swim bladder could still be used for breathing,

The WGD is estimated to have happened about 320 million years ago in the teleosts, which on average has retained about 17% of the gene duplicates, and around 180 (124–225) million years ago in the chondrosteans. It has since happened again in some teleost lineages, like Salmonidae (80–100 million years ago) and several times independently within
1040-638: The bottom, and inhabit rocky bottoms, ledges, ridges, and artificial reefs, including offshore oil rigs and shipwrecks . Like most other snappers, northern red snapper are gregarious and form large schools around wrecks and reefs. These schools are usually made up of fish of very similar size. The preferred habitat of this species changes as it grows and matures due to increased need for cover and changing food habits. Newly hatched red snapper spread out over large areas of open benthic habitat, then move to low-relief habitats, such as oyster beds. As they near one year of age, they move to intermediate-relief habitats as

Interest in recreational fishing for northern red snapper, and in the Gulf of Mexico in general, has increased dramatically. From 1995–2003, the number of Louisiana fishing charter guide license holders increased eight-fold. In 2017,

Males are occasionally produced at temperatures below 19 °C (66 °F) and can fertilise eggs that are then spawned by the female. This maintains genetic variability in a species that is otherwise highly inbred. Actinopterygii is divided into the subclasses Cladistia , Chondrostei and Neopterygii . The Neopterygii , in turn,

Around artificial reefs such as oil platforms, smaller fish spend time in the upper part of the water column while more mature (and larger) adults live in deeper areas. These larger fish do not allow smaller individuals to share this territory. The largest red snapper spread out over open habitats, as well as reefs.
