FSP Cuttlefish Diversification (Inshore)
To explore gear configurations that could improve selectivity in the current fishery and collect information on the catches, including associated species caught, that would help inform managers on management of the resource in future. The survey was carried out over 10 days during November 2011, sailing out of Plymouth. The area of operation for the survey was ICES Area VIIe off the South Devon coast The survey was carried out on board the FV Ocean Spirit (Figure 2), a steel-hulled trawler of 11.95 m registered length with a 220 kW engine.

A cuttlefish diversification FSP survey was conducted over 10 days during November2011 on board the FV Ocean Spirit. The area of operation for the survey was ICES AreaVIIe off the South Devon coast. The main objectives of the survey were to target cuttlefishinshore using a twin-rig otter trawl, and to explore gear configurations that could improvegear selectivity and to collect information on the catches, including of associated speciescaught, that would help inform management of the resource in future.In all, 23 hauls were conducted, 12 with a 150 mm square mesh panel fitted to the test net(Trial 1) and 11 with a fitted 200 mm square mesh panel (Trial 2). There were no preplanned transects, the area to be fished being based on the Skipper’s experience. A total of40 different species was measured in Trial 1 and 44 in Trial 2. The most abundant speciescaught were anglerfish (monkfish), cuttlefish, gurnards, lesser spotted dog fish and flatfish. In all, 9359 fish were measured during the survey. Comparison between catches taken with the control and test nets showed a substantialreduction in benthos retained when a square mesh panel was fitted. Overall, the results ofthe survey show that the use of a square mesh panel in the belly of the trawl significantlyreduced the quantity of some unwanted fish species and benthos, but had no detrimentaleffect on the retention of the target species.
