Abstract/Summary

Cuttlefish are currently the highest yielding cephalopod group harvested in the north-east Atlantic. English Channel cuttlefish show seasonal migrations to and from deep offshore wintering grounds, which results in a large number of smaller cuttlefish within the offshore stocks, some of which are caught by trawlers. Discarding small cuttlefish from trawls may give them the opportunity to migrate inshore and spawn, but only if they survive. This study examined survival rates of small (<15-cm dorsal mantle length) cuttlefish caught on board a commercial beam trawler. Overall, 31% of the small cuttlefish caught remained alive by the time they reached the sorting table (immediate survival rate). This survival rate dropped to 16% after specimens were subsequently held in an on-board aquarium system for up to 72 h (short-term survival rate). Measures that reduce the capture of small cuttlefish in the first place and/or increase their survival could potentially benefit the stocks.
