February 23, 2017 — For the past couple of years, Nantucket fishermen have had a hard time finding striped bass in the rips and alongshore where they were accustomed to catching them.
They think they know why: no squid.
“This was where all the bass were caught. Now, no bait, no fish, no stripers to speak of,” said Pete Kaizer, a charter boat captain and commercial tuna fisherman.
Kaizer and other Nantucket fishermen petitioned the state Division of Marine Fisheries to prohibit fish draggers and scallopers that tow nets or large metal dredges along the ocean bottom from state waters, up to 3 miles out from shore all around the island. The ban would run from May 1 to Oct. 31 with the idea of protecting spawning longfin squid.
Kaizer said squid boats target the squid when they spawn because they come together in large schools and are easier to catch. Following mating, female squid drop to the bottom and put down a sticky substance that adheres to the sandy bottom, rocks or vegetation. They then deposit tubelike sacks containing over 100 embryos apiece, that stick to that patch and can resemble an underwater chrysanthemum, but are prosaically known as “squid mops.”
Nets or dredges towed across the bottom can dislodge these mops or even bring them up to the surface along with fish or squid. There is some debate about whether any young can survive this, but some lab studies have shown that older embryos hatch prematurely when the mop is dislodged from its adhesive anchor and tend to die, said Lisa Hendrickson, a fishery biologist specializing in squid with the National Oceanic and Atmospheric Administration Fisheries Science Center in Woods Hole.
