Summer Flounder

Summer flounder, popularly known as fluke, is a large-toothed flatfish that lives in estuarine and coastal waters from Nova Scotia to Florida. These bottom-dwellers have been nicknamed “chameleons of the sea” because of their ability to change colour to blend in with the seafloor. Their namesake comes from the fact that they migrate inshore during summer months.

Summer flounder are brown or gray on their backs with white bellies. Their backs are spotted with at least five of these dark spots arranged in a distinctive “X” pattern.  They grow up to three feet and have both eyes on their left side. This flatfish is very popular due to his lean meat, delicate flavour and fine texture.

Summer Flounder

Summer flounder grow quickly and have a relatively short life, ranging from 12 to 14 years. They reach maturity at age two to three and spawn in the fall and early winter when they migrate offshore. Females release 460,000 to 4 million eggs, which hatch in the waters of the continental shelf. Currents pull the drifting larvae towards coastal and estuary areas where they develop into juveniles. At this point, the fish undergo a metamorphosis as their eyes gradually migrate to the left side of their head and the body flattens. The young flounder spend their first year in eelgrass beds of inshore areas. Mature fish live their life burrowing into seafloor sand, spending winters offshore and summers inshore. They eat a mixed diet of fish and invertebrates throughout their life.

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: Summer Flounder by Rod & Reel (USA)>], 'gear': <Gear: Rod and Reel>}

Rod and Reel

This fishery uses a rod, reel and lure or baited hook trailed behind a vessel at low speed to catch fish. Each fish is individually hooked and hauled aboard by hand.


{'fisheries': [<License: Summer 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.
