Longfin Squid

Longfin squid, as their name suggests, are characterised by a long fin, at least half the length of the mantle. They can reach up to 1.6 feet in mantle length, but are usually less than one foot. They range from Newfoundland to the Gulf of Venezuela in South America.

Longfin squid are pink or orange and mottled with brown or purple. Besides their long fin, they feature large eyes covered by a cornea. Although considered a mollusk, squid don’t have an outer shell but rather have an internal shell called a “pen.” A favourite for calamari, edible parts include the tentacles, the mantle (tube) and the fins (wings).

Longfin Squid

Longfin squid have a short life span: they reproduce right before they die, at around just six to eight months old. Spawning occurs year-round, with peak production in winter and summer, with females typically spawning an estimated 3 000 to 6 000 eggs. Eggs hatch between 11 and 26 days later, depending on water temperature. Longfin squid also grow fast; given this and their short life span, even without fishing the entire population replaces itself every six months or so. Squid are aggressive hunters, feeding on fish even larger than they are. A school of squid can decimate an entire school of herring, leaving only heads and tails in their wake. 

Food Info Longfin Squid


  • Appearance: Ivory coloured, with a shiny, lightly speckled membrane. When cooked, squid should be opaque white.
  • Texture/Body: Firm flesh.
  • Flavour: Mild, slightly sweet.
  • Perfect serve:  Squid is one of those tricky ingredients which, prepared incorrectly, can turn out as a rather chewy, rubbery mouthful. Prepared carefully though, it makes for a melt in the mouth treat. Of course, there’s the old standby – battered and deep fried – a favourite worldwide for a reason; but why not try it stuffed whole with a blend of cheeses and topped with a marinara sauce for something extra special. It also works really well in pasta dishes or as a fried calamari sandwich on a crusty roll topped with a chipotle-mayonnaise dressing, onions, lettuce and tomato.

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: Longfin Squid 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.
