It is a moderate source of omega-3 eicosapentaenoicacid (EPA), docosapantaenoicacid (DPA) and docosahexaenoic acid (DHA) fatty acids. Studies suggest a diet rich in fish that are high in omega-3 fatty acids can curb or prevent cognitive decline, dementia, depression, neuropsychiatric disorders, asthma, and inflammatory disorders. It's lean white meat is a good source of polyunsaturated fatty acids (PUFA). Its white, flaky meat is firm and composes all the essential amino acids in right proportions. Red snapper is excellent source of protein (20.5 g/3.5 oz -36.6% of RDI). American Heart Association (AHA) recommends consumption one to two meals of non-fried fish to fulfil requirements of essential fatty acids, protein, minerals and fat-soluble vitamins. Red snapper holds 100 calories per 3.5 oz. It is an average sources of omega fatty acids, protein, minerals and fat-soluble vitamins like vitamin A, E and D. Red snapper fish is an non-oily, marine, white fish. As the juveniles mature, they move to the reefs where they stay as adults.
Spawning occurs during summer in areas away from reefs, at depths of 60-120 feet over flat sandy bottom areas. They attain sexual maturity at about 2-3 years and 375 mm in fork length. In the initial years of their life, red snappers grow quickly, and then their growth slows steadily as they reach full-size adult fish. Big adults prey on smaller fishes, which they find in flat bottom areas adjacent to the reefs. They feed on zooplankton, fish eggs, worms, shrimp, and squid. Northern red snappers are carnivorous and bottom-oriented predators. Red snapper lives in the subtropical continental shelves bordering the Gulf of Mexico and the Atlantic Coast as far as North Carolina, over deep reefs and rocky bottoms at depths of 50-620 feet. It also has a black spot on each side lane snapper has a rounded anal fin. Lane snapper (Lutjanus synagris) has a similar body shape and color, but it also has eight narrow yellow lines that run the length of the fish. The maximum age is estimated at 40-50 years. The adult northern red snapper reaches an average length of 24 inches and may weigh 5-15 pounds. Juvenile red snappers exhibit a dark spot on the upper sides below the anterior soft dorsal rays that disappear as they grow onto adults. populations.Red snappers are deep-bodied fish with scarlet red upper body and angular fins, and a paler underside. Further work is needed to improve the draft reference genome and estimate dispersal parameters in order to design management units for U.S. Little evidence of population subdivision was found among northern red snapper populations, consistent with previous genetic studies. These results, coupled with the finding of divergent selection impacting several genomic regions during sliding window analysis, suggests that northern and southern red snapper should, at minimum, be managed as distinct population segments. Northern and southern red snapper diverged significantly (average F ST estimate 0.188) and Bayesian clustering suggested a complete lack of current gene flow between the two taxa. Genetic variation among four geographic populations of northern red snapper and one population of southern red snapper ( Lutjanus purpureus) was studied using 6,890 SNPs generated by RAD sequencing.
The map consists of 7,964 markers distributed across 24 linkage groups and was used to anchor genome contigs obtained during assembly of P-454 and Illumina sequencing reads. Microsatellite loci and Single Nucleotide Polymorphisms (SNPs) generated through Restriction Site Associated DNA (RAD) sequencing were assayed in 5 outbred full-sib families to construct a high-density linkage map of the red snapper genome. Eighty-four new microsatellite markers were developed through screening of Illumina paired-end sequencing reads. This work aimed to develop genomic resources for the genetic management of aquaculture programs and to investigate population structure using high-throughput sequencing technologies. The northern red snapper ( Lutjanus campechanus) is a highly targeted reef fish candidate for marine aquaculture and stock enhancement in the southern United States.
