Objectives and Narrative |
Objectives
1. To internally tag adult cod from the Viking area with G5 data storage tags (DSTs) for investigations of movement and temperature experience. 2. To tag monkfish and haddock using redeployed DSTs from past projects. 3. To biologically sample cod and prespawning haddock. 4. To collect live juvenile haddock and cod for use in laboratory growth trials. Report Scientific equipment was loaded onto the vessel on 3 April. Staff joined the vessel on the morning of Wednesday 4 September. Weather was fine and Celtic Voyager departed at 1000. The gear was shot in Aberdeen Bay to tighten the wires, assess performance and familiarise operations. Although an optimal spread of the gear was not achieved, the trial was deemed satisfactory and the separator panel functioned to separate cod, haddock and flatfish. The catch from the two cod-ends was worked up into a species/length/frequency composition. Following this, immediate passage was made for Shetland to take advantage of fine weather. Upon reaching Shetland, however, a heavy offshore swell and northerly winds prevented immediate passage east toward the Viking Bank area, so the morning of the 5 April was spent towing in inshore waters to try to improve the spread of the gear and angling for cod. On the morning of 6 April the vessel steamed east for the Bressay Ground and began prospectively towing for cod in the region, gradually working further east as the swell subsided. It proved slow and difficult and at times potentially dangerous to manoeuvre the live fish cod-end from the stern to the starboard side. Since tows were limited to 30 minutes, bulk was not proving to be significant and so a normal cod end was affixed and operations continued with the catch being opened on the afterdeck. The square mesh panel proved highly effective at preventing undesirable bycatch of benthic animals such as urchins and Nephrops. |
