The trawlers work in pairs to trap schools of herring by towing a large net between two vessels. The nets trap and kill marine mammals as well as scoop cod, haddock and other non-targeted fish or bycatch, environmentalists said.
The CHOIR coalition -- an unlikely alliance of environmental groups and commercial and recreational fishermen -- has fought to restrict mid-water trawlers from fishing along the southern coast of Maine during summer months. The group contends that vessels using purse seine nets -- circular nets that are closed off by drawstrings -- have less bycatch and are better for the marine environment"
