Squid emerged on the ecological timeline about 500 million years ago, during the Cambrian, a particularly prolific period. They are further delineated into the class Cephalopoda, meaning 'head foot,' the super order Decapodiformes, meaning 'ten-footed,' and the order Teuthida. Squid are actually mollusks, though they don't really resemble their relatives the gastropods (snails and slugs), bivalves (clams, oysters, and scallops), scaphopoda (tusk shells), and polyplacophorans (chitons). The giant squid's smaller cousins, though less famous, are better known and no less fascinating. These stories are all likely based on sightings of the giant squid, Architeuthis dux, a real but elusive creature and one of the world's largest known invertebrates. The size suggested the largest squid known at the time. The animal he described had 30-foot-long arms, weighed 700 pounds, and had a head “as big as a cask.” In 1978, sharp, curved hooks cut up the rubber coating on the hull of the USS Stein. Jules Verne later wrote in his classic novel, 20,000 Leagues Under the Sea, of a monstrous creature whose massive arms 'could entangle a ship of five-hundred tons and hurry it into the abyss of the ocean.' In the first century B.C., Pliny the Elder – Roman author, naturalist, and natural philosopher, as well as naval and army commander of the early Roman Empire – first wrote of an enormous squid in his Natural History. In Homer's Odyssey, Odysseus had to navigate his boat around the many-headed sea monster, Scylla. ~Jules Verne, Twenty Thousand Leagues Under the Seaįor thousands of years, stories have existed of giant, many armed sea creatures. “With its untold depths, couldn't the sea keep alive such huge specimens of life from another age, this sea that never changes while the land masses undergo almost continuous alteration? Couldn't the heart of the ocean hide the last-remaining varieties of these titanic species, for whom years are centuries and centuries millennia?” The Lore & Legend of Texas Saltwater Fishing.Real-time communication to vessels regarding hotspots of marine mammal interactions.Outreach to fishermen to educate them on actions to take in the event of a marine mammal interaction.Fishing must occur seaward of the 50-fathom depth line to reduce finfish and longfin inshore squid bycatch.Measures to prevent or minimize bycatch include:.Finfish such as butterfish, hakes, longfin squid, summer flounder, herring, spiny dogfish, and Atlantic mackerel are also incidentally caught in this fishery. Small-mesh bottom trawls can incidentally catch marine mammals and large pelagic species, including pilot whales, common dolphin, swordfish, and a variety of sharks, ray, and tuna species.

Sandy or muddy habitat, where squid are fished, is less sensitive to the impacts of trawling.

The fishery is open year round, but the squid aren’t available in commercial quantities year round.

The majority of shortfin squid is harvested June 1 through October 31 using small-mesh bottom trawls.Gear types, habitat impacts, and bycatch:.Harvested for bait domestically, and exported for bait and food.The majority of landings come from Rhode Island and New Jersey.Fisheries for shortfin squid reflect the species’ seasonal migrations.These figures may not match other agency sources of data due to confidential information. In 2019, commercial landings of shortfin squid totaled approximately 58 million pounds, and were valued at approximately $27.3 million according to the NOAA Fisheries commercial fishing landings database.They are nearest the seabed during the day, and higher in the water column during the night. Shortfin squid undergo daily vertical migrations between cooler deep water and warmer surface water.Seabird predators include shearwaters, gannets, and fulmars. They are food for many fish, including bluefin tuna, silver hake, red hake, bluefish, goosefish, fourspot flounder, Atlantic cod, sea raven, spiny dogfish, and swordfish.Shortfin squid are visual predators that eat crustaceans, fish, and other squid, including their own species.This makes them extremely sensitive to climate-driven changes. Shortfin squid have extremely variable birth, growth, and maturity rates.Spawning can occur year round with seasonal peaks from October to June. Females can release multiple egg masses during a single spawning season, but die after they spawn.They have a high natural mortality rate, and a long spawning season. Shortfin squid live for less than one year.
