Editor's note: October is National Seafood Month, and to celebrate, we’ll be featuring a series of blog posts about seafood, sustainable fishing and health. Today we’re schooling you on bottom trawling.
When you’re enjoying a tasty seafood meal, you’re probably not thinking about habitat destruction and accidentally caught marine animals. (Or at least I hope you’re not, it might give you indigestion.) But unfortunately, in many cases, before seafood gets to your plate, those two things may have been part of the equation.
Take bottom trawling, which is the most destructive commercial fishing method on the planet. Bottom trawlers scrape huge, heavy nets across the seafloor, destroying everything in their path. Trawling destroys more seabed habitat each year than the world’s annual loss of tropical rainforest. One study found that trawling destroys 16 pounds of marine animals for every pound of sole brought to markets.
Trawling is designed to catch as many fish as possible, and is used particularly to target shrimp, cod, haddock, flounder, and rockfish. Dredging, which is a similar practice, is used to catch shellfish like scallops and clams. Currently, more than half the fish eaten in the US is the product of trawling.
Fishermen have been trawling for years, but in the 1980s, technological advances allowed them to begin trawling through coral reefs, which they previously had to avoid to protect their fishing gear.
Unfortunately, we know now the huge damage that even one pass of a trawler can cause reefs. In one study in Alaska, as much as two-thirds of some sponges damaged by one pass of a trawler had not recovered a full year later.
Reefs are an important home for fish, so trawling can also ruin fish stocks into the future – even for responsible and recreational fishermen.
Recently, we’ve seen important measures to stop trawling. Earlier this year, a group of North Pacific nations, including the US, agreed to protect more than 16.1 million square miles of seafloor from trawling. Just a month later, Belize banned trawling from its waters.
We’ve made a lot of progress to stop this destructive fishing method. You can help by paying attention to the seafood you buy.
