The Effects of Derelict Blue Crab Traps on Marine Organisms in the Lower York River, Virginia
—Derelict (abandoned or lost) traps targeting blue crab Callinectes sapidus have the potential to affect the blue crab fishery and other marine-oriented species. We used sidescan sonar to locate derelict traps and assess their extent and accumulation rate. Experimental traps were monitored at four locations to calculate catch rates of marine organisms and trap degradation rates. In 2006, 635–67...

Totally 56 traps of four most commonly used types, "Rectangular trap", "Round trap", "Opera house trap" in two colors of "black" and "blue", and "Fathoms plus" only in black...
متن کاملMarine species mortality in derelict fishing nets in Puget Sound, WA and the cost/benefits of derelict net removal.
Derelict fishing gear persists for decades and impacts marine species and underwater habitats. Agencies and organizations are removing significant amounts of derelict gear from marine waters in the United States. Using data collected from repeated survey dives on derelict gillnets in Puget Sound, Washington, we estimated the daily catch rate of a given derelict gillnet, and developed a model to...
متن کاملUsing underwater video to evaluate the performance of the Fukui trap as a mitigation tool for the invasive European green crab (Carcinus maenas) in Newfoundland, Canada (#20010)
20 The European green crab (Carcinus maenas) is a destructive marine invader that was first 21 discovered in Newfoundland waters in 2007 and has since become established in nearshore 22 ecosystems on the south and west coast of the island. Targeted fishing programs aimed at 23 removing green crabs from invaded Newfoundland ecosystems use Fukui traps, but the capture 24 efficiency of these traps...
