Summary

The behavior of inshore squid (Dorytheuthis pealeii) in response to a Nordmore-style finfish bycatch reduction grid was evaluated in Nantucket Sound off Cape Cod, Massachusetts (United States). Squid avoided the grid and escape by jetting and changing directions. Only 6.4% of the squid became stuck on the grid and 83.9% of these were able to eventually pass between the grid and its spacing into the codend. Squid approaching the grid from the top with their mantel oriented toward the grid were more likely to be caught.
