Using RAMP in fishing gear design

RAMP has been used in the Bering Sea to measure real-time reflex impairment and predicted mortality in tanner and snow crabs contacted by bottom trawl footropes that are part of trawls used to capture walleye pollock.  The RAMP data can be used in real time to adjust trawl performance in an effort to engineer trawls for reduced crab mortality.  Rapid access to reflex impairment data during the research cruise means that the researchers and fishers can adjust and test trawl performance immediately, without waiting for an additional future cruise.
