Capture probability of a survey trawl for red king crab (paralithodes camtschaticus)... To estimate survey trawl capture efficiency for red king crab, an experiment was conducted with an auxiliary net (fitted with its own heavy chain-link footrope) that was attached beneath thetrawl to capture crabs escaping under the survey trawl footrope....

Quantification and reduction of unobserved mortality rates for snow, southern tanner, and red king crabs (chionoecetes opilio, c. bairdi, and paralithodes camtschaticus) after encounters with trawls on the seafloor... Crabs were more likely to die after encountering the footrope than the sweeps of the trawl, and higher death rates were noted for the side sections of the footrope than for the center footrope section....
