Yellowtail Flounder

Yellowtail flounder are a small-toothed flatfish that live on sandy bottom along the continental shelf from southern Labrador to Chesapeake Bay. These oval-shaped bottom-dwellers live in waters between130 and 230 feet (37 and 91 metres) deep and are relatively sedentary. They are named after their yellow tail fins.

Yellowtail flounder are brownish or olive on their upper sides and are tinged with red and marked with large, irregular rusty red spots. Their underside is white except for the area between the body and tail with is yellow. They grow up to 22 inches and have both eyes on their right side. This flatfish is very popular due to his lean meat, delicate flavour and fine texture.

Yellowtail Flounder

Yellowtail flounder grow quickly and have a relatively short life with most only reaching the age of 7. They reach maturity earlier than most flat fish. By the age of three, most females begin to spawn in the spring and summer, depositing their eggs on the ocean floor where they are fertilized. The larvae then float to the surface where they remain for two months. When they hatch, the flounder’s eyes are symmetrical with one on each side of its head. As the fish grows, it takes on its flattened shape and the left eye slowly drifts over to the right side of its head next to the other eye. After this metamorphosis, the young fish settles along the seafloor where it feeds on worms and crustaceans.

These crabs mate at the time of maturity, which is approximately 3 years of age. Females are smaller than males; this is because the development of reproductive tissues required more energy for females, leaving less energy available for continued body growth. They grow through a process known as molting—regularly shedding their shell and growing a new, larger one. They continue to molt and grow after they have reached sexual maturity. During the breeding season, the crabs leave their borrows in a phenomenon characterized by mass mate-searching events. Once mating/fertilization has occurred, females spawns in the water. The larvae released during the rainy season develop in offshore waters and return to coastal waters five to eight weeks after larval release.
Mangrove crabs are important fishery resources in all Brazilian coast, mainly in the north and northeast where many fishermen depend upon their catch. In addition to its social and economic importance, the mangrove crab is a “keystone” species in ecosystem, they playing an important role in the processes of nutrient cycling and energy transfer.

Fishing Methods

{'fisheries': [<License: Yellowtail Flounder by Bottom Trawl (USA)>], 'gear': <Gear: Bottom Trawl>}

Bottom Trawl

This fishery uses a large cone-shaped net that is dragged along the seafloor to catch fish. As the net is towed at low speed, hydrodynamic forces push two "otter boards" outwards opening the mouth of the net and capturing fish in its path.
