  • Description:
    The video is part of the Ocean Today educational video collection (sub-collection: Go fish). It has open captions and can be viewed in regular (640 x 36) or high resolution (1280 x 720). Video's transcript: "NARRATOR: Bycatch is the name given to fish and other ocean animals that are unintentionally caught by fishing gear. Scientists and gear specialists from the University of New Hampshire are working with fishermen to test a new 'selective' fishing net. This fishing net, called a trawl, is compatible with ground fish regulations and would reduce the amount of bycatch while fishing for haddock. In the waters off New England, haddock are rebounding at a faster rate than other fish species, particularly codfish. This team of scientists and fishermen decided to figure out a way to catch the haddock and let the codfish go through the net. The team first looked at the particular habits of haddock and cod. When the fishing net approaches the haddock, they tend to go up higher in the water column, and codfish tend to go down. So the idea was to design a net with a specialized separator composed of ropes that guide the haddock towards the top while releasing cod through an opening on the bottom. The team put the new trawl through its paces to see if it would work. After six days of fishing, the results were in. The new 'selective' trawl was catching more haddock and less cod than a traditional net. Scientists and fishermen have learned a lot from each other and from working together on this exciting project. The new fishing net design allows fishermen to make a living by giving them access to healthy fish stocks while allowing depleted fish stocks to continue to reproduce in the ocean and return to healthy numbers."
