The EU Technical Conservation Regulation restricts the fish by-catch to 5% by weight of all marine organisms on board, but a low weight of whitefish could still contain a significant number of young whitefish. Compliance with the EU Regulation is monitored by Danish and Norwegian authorities at the ports, where a sub-sample of the landing is taken and analysed for species composition, whilst monitoring at sea is carried out bym national inspectors, including those of the UK. It is possible that the effectiveness of port-based monitoring could be compromised by spoilage of small gadoid by-catches in the hold, and that monitoring at sea could be compromised by spatial patchiness, so there has been concern within the UK industry that the official by-catch data may not reflect the true extent of by-catches. This project therefore aimed to observe and record on a haul by haul basis the catch composition obtained when fishing a small meshed sandeel net at a time of the year when young whitefish of the year could conceivably be present in significant numbers on sandeel grounds. Some hauls were also carried out on nearby whitefish grounds using both a whitefish trawl and the sandeel trawl. The project used an English whitefish trawler, the Jubilee Quest, a relatively low power (465 hp) vessel of 22 m rigged with a commercially-manufactured 16 mm 3 mesh sandeel net made for the purpose in Denmark, or with the vessel’s own whitefish trawl with 100 mm cod-end. Two trips were undertaken, from 3-12 July and from 17-28 July, when 0-group gadoids might be present. Based on satellite records and other sandeel fishing information, the area of operation was chosen to be the western Dogger, and then further south on The Hills FSP Project 1, Undertaken in July 2003 with a fine-meshed net on sandeel grounds in the north-east Dogger Bank area of the North Sea.
