Indeed, cod livers are processed to make these health products, as it a good source of vitamin A, D, E and omega-3 fatty acids. With its versatile taste, the fish can be easily adaptable to all methods of cooking including braised, poached, steamed, baked, fried, and even using it in a broth.
Unlike most fish, the unique quality of tuna is probably its pink to dark red flesh which is velvety smooth, soft and delicate. In Japanese restaurants, the fatty tuna belly (Otero) is considered one of the most highly prized ingredients due to its creamy flavor and melt-in-your-mouth texture.
Canned versions of cooked tuna are also available, and it often comes shredded as flakes perfect for spreading on toast. Studies have shown that consumption of the pink fish may be linked to lower heart diseases.
And if a salmon fillet may be too fishy to some, break it up and add some mayonnaise to use it as a paste for sandwiches, or simply mash with some vegetables and potatoes to make it into a fishcake. Thread fins are found in both tropical and subtropical waters of all oceans, and generally gather at sandy, muddy bottoms in depths of less than 150 meters.
They are easily identified due to their structure, including their pectoral fin rays, which is divided into two sections. In Teacher cuisine, thread fin is often steamed using only ginger sliced and fermented soda beans (touched).
Alternatively, go for a Western presentation and grill the fish with a dash of sea salt, olive oil and freshly ground black pepper. With delicate, moist, white flesh, and fine, firm texture, the snapper is great for a variety of recipes.
One simple and healthy way to serve the grouper is to steam it with light soy sauce, julienne ginger, and top with spring onions. It is distinguished by the presence of two widely separated dorsal fins, small triangular mouths with closely set teeth, and the absence of a lateral line organ.
Its body is elongated and rather stout, and its color a dark bluish on the top and silver along the sides. The sea bass is identified by its elongated body, small scales, and large mouth.
To ensure the freshness of the raw fish, look out of sparkling white and translucent flesh, rather than opaque ones. While the sea bass is versatile and can be cooked in a variety of ways, take extra care not to overcook it.
It is considered an oily fish, and when eaten fresh, it is light, plump, briny and relatively mild. Most of the time though, anchovies come already packed in jars or cans and cured in olive oil, salt, or pickled in vinegar.
Mackerel are typically recognized by vertical stripes on their backs and deeply forked tails. Rich in nutrient and omega-3 fatty acids, the mackerel is oily, making it an excellent fish for smoking.

Smaller gag are a lot of lighter in coloring, and have numerous dark brown, or charcoal, kiss-like marks along their sides. “Young gag grouper will live in oyster reefs, estuaries and seagrass beds from Massachusetts to Cape Canaveral, Florida.
The coloration of red grouper helps to distinguish this species from gag with its head and body being dark reddish brown, shading pink or reddish or even pale pink along the lower part of its body,” Nash said. “In North Carolina, gag will typically spawn in February and have clear larvae, which then make their way into estuaries.
As water temperatures start to go down in the fall, juvenile gag will migrate from estuaries to offshore hard bottom habitat and larger members of their species,” said Seward. Seward noted that all grouper are considered protogynous intersex, “that is they start their lives as females, and a part of the population will morph, or make the change, to males as they get older.
Females start to reach sexual maturity when they are about 24 inches in total length and about 3 years old. They are voracious predators, and will feed on whatever they can capture including scad, snapper, grunt, sardines, crabs, porgies, shrimp and squid, said Seward.

“The red grouper is also a protogynous intersex and females are sexually mature by the time they reach 4 years old,” Seward said. Females typically will let go an average of 1.5 million pelagic eggs that stay at the surface for between 30-40 days before finally settling down to the bottom.
“ Red grouper may live to be as old as 25 years of age, with older specimens reaching a size of 32.5 inches and up to 25 pounds. They will feed on lobster, shrimp, octopus, crabs and fish that are found close to their preferred reef habitat,” Seward said.
Bottom fishing is the best way to catch gag grouper, using live bait, including squid and cigar minnows. Use a depth finder to find deep-water rock ledges, artificial reefs and shipwrecks, a gag grouper ’s favorite hiding place.
Recreational and commercial fishermen are required to use hooking tools when fishing for the snapper grouper species. “This prohibition does not apply to fish harvested, landed and sold before the annual catch limit is reached and held in cold storage by a dealer,” said North Carolina Division of Marine Fisheries Executive Assistant to Councils Steve Poland, who is also a representative with the South Atlantic Fishery Management Council.
While populations of gag grouper have remained healthy, a 10-year effort to rebuild the red grouper stock has failed, leading to new, stricter rules and regulations taking effect this year. Therefore, on Sept. 27, 2017, NFS sent a letter to the council stating that the South Atlantic red grouper stock was not making adequate progress toward rebuilding.
So, NFS took steps in 2018 to immediately end overfishing of red grouper by reducing the total commercial and recreational annual catch limits, based on the acceptable biological catch recommendation from the council’s Scientific and Statistical Committee. “For red grouper, this final rule extends the closure season formerly from January to April, to January through May of each year for the next ten years for the commercial and recreational portions off North and South Carolina, and establishes a commercial trip limit,” said Poland.
This final rule establishes a commercial trip limit for red grouper harvested in the South Atlantic EEA of 200 pounds, gutted weight. The trip limit is expected to help rebuild the red grouper stock by discouraging directed commercial fishing for the species, although it is not likely to substantially reduce the current level of commercial harvest of red grouper, according to the National Register.
The red grouper has a body with a standard length which is 2.6 to 3 times as long as it is deep. The properly is subangular with the serrations at its angle being slightly enlarged and the upper edge of the gill cover is straight.
The They are dark reddish brown on the upper part of the head and body, shading to paler pink on the underparts, they are marked with lighter spots and blotches across their body and there are darker margins to the fins. This species has a maximum published total length of 125 centimeters (49 in), although they a more commonly found at lengths around 50 centimeters (20 in), and a maximum published weight of 23 kilograms (51 lb).
The redgrouper's typical range is coastal areas in the western Atlantic, stretching from southern Brazil to North Carolina in the US and including the Gulf of Mexico and Bermuda. The red grouper is a reversal, largely sedentary species which has an extended (~40 day) pelagic larval stage before it settles in shallow coastal hard bottom habitat as juveniles.
While primarily eating benthic invertebrates, the red grouper is an opportunistic feeder in the reef community. The diet commonly includes mantid and portend crabs, juvenile spiny lobster, and snapping shrimp, with the occasional fish.
The red grouper is of moderate size, about 125 cm and weighs 23 kg or more. When aggravated (they are highly territorial) or involved in spawning activities, these fish can very rapidly change coloration patterns, with the head or other parts of the body turning completely white, and the white spots appearing more intense.
Red grouper (Epimetheus Mario) on an excavated site on Pulley Ridges on the West Florida Shelf Red grouper actively excavate pits in the seafloor. They start digging in the sediment from the time they settle out of the plankton and continue throughout their lifetime.
They use their caudal fin and their mouths to remove debris and sediment from rocks, creating exposed surfaces on which sessile organisms actively settle (e.g., sponges, soft corals, algae). The exposure of structure also attracts a myriad of other species, including mobile invertebrates and a remarkable diversity of other fishes, from bodies and butterfly fish to grunts and snapper.
The lionfish Steroid Holsteins started invading red grouper habitat by 2008, from Florida Bay to the Florida Keys and offshore to Pulley Ridge, a despotic coral reef on the West Florida Shelf west of the Dry Tortugas. Known for being extremely capable predators on small reef fish, scientists are very interested in determining the extent to which their invasion changes the functional dynamics of associated communities.

The majority of media and political attention is focused on red snapper, but there are several other reef fish in the Gulf of Mexico that are of commercial and recreational importance. Fishermen are putting our heads together to independently address this issue instead of waiting for politics and management to catch up.
Are we catching less red grouper because the red snapper population has expanded as it recovers? Thanks to successful management under the Magnuson-Stevens Act, red snapper populations are rebounding and their range is expanding.
Solving the problem of a declining of red grouper population is not going to be an easy task, but I have confidence that our collaboration between industry, scientists, and managers, together with the best-available science mandated by Magnuson-Stevens, can successfully recover the red grouper fishery.
