So, how does a bottom trawl work? Bottom trawls are very large nets that are dragged on the seafloor to catch groundfish and other species. The trawl nets are unspooled from the back of the ship. Once the entire net is in the water it is lowered to the bottom of the seafloor.
The ship will then tow the net along the bottom of the seafloor for a pre-determined length.
The net is then pulled back in and the catch is dumped into the sorter. During this trip, the ship will make about 100 trawls in the 12 days at sea.
During our first trawl of the morning today (1 a.m.) we caught a 4-foot Sand Bar Shark and a large ray!
QUESTION: What does the word "trawl" mean?
