Cruise summary report
|Ship name (ship code)||RV Cefas Endeavour (74E9)|
|Cruise period||2008-01-06 — 2008-01-15|
|Port of departure||Aberdeen, United Kingdom|
|Port of return||Lowestoft, United Kingdom|
1. To estimate escape rates using additional bags that close the gab below and behind the fishing line on the standard GOV survey gear (Cefas Endeavour) and to compare the standard catch rates with commercial vessels fishing along side using commercial gear on soft bottom habitats (tows in parallel) and hard ground habitats (in the vicinity). Samples for age will be collected for cod, plaice and haddock and for other species as time allows.
2. To determine the behaviour of fish in response to the standard GOV gear and to investigate means of escape a low light level camera will be installed on the net to make video recordings for later evaluation.
Additional aim: If time allows, additional tows using the Poly Rockhopper GOV may be carried out.
Narrative: (All times GMT)
Cefas Endeavour sailed from Aberdeen at 2130h on the 7 January and headed southeast to Swallow hole to do a shakedown tow and tighten the windings on the winch after the dry dock. The standard GOV, fitted with three ground gear bags was successfully deployed in Swallow Hole, however, weather started to deteriorate and no more tows were possible that day. The vessel steamed southwest towards the Yorkshire coast throughout the rest of Monday, ready to rendezvous with the FV Our Lass II and the FV Jubilee Quest the following morning. The FV Our Lass II fished a commercial soft groundgear net in parallel with the Cefas vessel and the FV Jubilee Quest fished in close proximity but on hard ground stations with a commercial hard ground gear. With the weather having moderated enough to fish, the gear was deployed at 0729h on 8 January and two successful tows were carried out. On the third and forth tow of the day, the low light camera was attached to the selvedge, in an attempt to show movement of fish in the bosom of the groundgear. Unfortunately, due to the amount of sediment in the water following the storms, no footage was usable.
