New SMAST camera can help assess cod stocks in Gulf of Maine

Researchers from UMass Dartmouth say they have successfully tested an underwater video-survey system that they hope will provide an accurate method to assess Atlantic cod stocks. In collaboration with fishermen, the research team recently placed high-resolution cameras in an open-ended commercial trawl net on Stellwagen Bank in the Gulf of Maine, known as one of the world’s most active marine sanctuaries. The cameras captured images of cod and other groundfish as they passed through the net. Periodically, researchers from UMD’s School for Marine Science & Technology closed the net for short periods to collect length, weight, and take other biological samples from some of the fish. The fish are unharmed and are returned to the sea. The system is design to be portable, so scientists can set it up on different fishing vessels. Professor Kevin Stokesbury, head researcher on the project, said the video system is an important tool at a time of uncertainty about the groundfish stock in the Gulf of Maine.
