| 1: North East Cod |
Oct-04 |
NE coast of England |
Allegiance and Independence (pair trawl) and Christina (otter trawl) [PDF, 518KB] |
| |
Purpose - To repeat the otter-trawl survey of NE cod and selected bycatch species carried out in 2003. To compare the size/age compositions of cod catches between a single-vessel otter trawl and a pair-trawl. To examine day-night differences in catch rates. |
| 2: Western Channel sole and plaice |
August – October 2004 |
Western English Channel and Approaches |
Nellie and Lady T Emiel (beam trawl) [PDF, 1.7MB] |
| |
Purpose - To repeat the beam-trawl survey of western Channel sole and plaice and selected bycatch species carried out in 2003. To attempt to confirm the size of the 2002 year-class of sole using open gear in Lyme Bay. |
| 3: Western Anglerfish |
October - December 2004 |
Celtic Sea and Western Approaches |
Bill Rowney and Twilight (beamtrawl). [PDF, 1.85MB] |
| |
Purpose - To repeat the beam-trawl survey of Celtic Sea anglerfish and selected bycatch species carried out in 2003. To investigate the effectiveness of an “environmental panel” designed for reducing the bycatch of benthic organisms and debris. |
| 4: Irish Sea roundfish |
February - March 2005 |
Western and Eastern Irish Sea (two separate surveys) |
Eastern Irish Sea: Isadale (otter trawl); Western Irish Sea; Beniah IV(semi-pelagic trawl) [PDF, 498KB] |
| |
Purpose -To repeat the surveys of cod and selected bycatch species carried out in the western Irish Sea with extension into the Clyde (semi-pelagic trawl gear), and in the eastern Irish Sea (demersal otter trawl) in spring 2004. To tag cod on spawning grounds and the North Channel/Clyde using conventional tags. |
| 5: Western Cod |
February - March 2005 |
Celtic Sea |
Josie Grace (twin-rig otter trawl) [PDF, 642KB] |
| |
Purpose - To repeat the otter-trawl survey of Celtic Sea cod and selected bycatch species carried out in spring 2004. To extend the survey to include the Irish Coast. To tag cod on spawning grounds using conventional tags. |
| 6: North East Nephrops |
October 2004 - January 2005 |
Farne Deeps off NE coast of England |
Nephrops survey: Kristenborg, Star Divine, Gallant Venture and Quo Vadis (single-rig Nephrops trawl) [PDF, 327KB]
Gear selectivity trials: Success III (twin-rig Nephrops trawl); Trudy May and Endeavour(single-rig Nephrops trawl). [PDF, 631KB]
|
| |
Purpose - To carry out a survey of Nephrops on the Farne Deeps using standard Nephrops trawls, mainly to examine catch rates and size compositions for comparison with the results of Cefas camera surveys of burrows. To carry out trials with new designs of Nephrops trawls aimed at reducing discarding of under-sized fish. |
| 7: North Sea plaice and lemon sole |
August – September 2004. |
NE coast of England |
Jubilee Quest and Jubilee Intrepid (twin-rig scraper trawl) [PDF, 860KB] |
| |
Purpose - To carry out a survey of plaice and lemon sole on the fishing grounds off the NE coast of England and east coast of Scotland, using commercial twin-rig Scraper trawls. To examine the catch composition in this fishery, particularly the bycatch of cod. To compare the catches between 100mm and 120mm mesh cod-ends, especially in relation to the retention of lemon soles, and to compare the catches between various combinations of cod-end mesh and square-mesh-panels. |
| 8: Gear selectivity in the Irish Sea |
September - November 2004 |
Western and Eastern Irish Sea (two separate projects) |
a) Eastern Irish Sea: Kiroan (twin-rig otter trawl). [PDF, 271KB]
b) Western Irish Sea: Golden Bells II (twin-rig Nephrops trawl), Rhodanna and Margreta-M (single-rig Nephrops trawl). [PDF, 860KB]
|
| |
Purpose -
a) To examine the effect on catches of using 80mm and 110mm cod-ends in the eastern Irish Sea plaice fishery using twin-rig otter trawls. To investigate the bycatch of cod in the eastern Irish Sea plaice fishery.
b) To provide data on catch composition of the different types of Nephrops trawlers in the fleet operating from Northern Ireland, with particular emphasis on bycatch and discarding of cod and whiting. To provide information relevant to the design of a forthcoming FIFG-funded gear selectivity trial of Nephrops trawls in the Irish Sea involving ANIFPO and DARD(NI).
|
| 9: Pout bycatch mitigation |
November - December 2004. |
Pout box off eastern Scotland |
Swanella (Industrial trawl and modified whitefish trawl). [PDF, 508KB] |
| |
Purpose -To determine the potential reduction in bycatch of whitefish when a sieve net is incorporated into a commercial Norway pout trawl. |
| 10: Celtic Sea sole and plaice |
February 2005 |
North Cornwall coast |
Nellie (beam trawl). [PDF, 321KB] |
| |
Purpose - To carry out a beam-trawl survey of sole and plaice off the north coast of Cornwall, with particular emphasis on identifying areas where clean catches of each species can be made. |
