Otterboard Performance and Behaviour

Purpose of this Manual The Sea Fish Industry Authority (U.K.), IFREMER (France) and DIFTA (Denmark) have collaborated on an EC funded project to assess the performance of a wide range of otterboards which are currently available to fishermen. This manual is based on the results of this project. It is intended for those actively involved in fishing, although much of it will interest persons active in the gear technology field. This manual has the following objectives:- To define terminology and explain the technical operation of otterboards. To provide information on the methods used and the results obtained during the otterboard tests. To provide information for calculating the equivalent sizes of different types of otterboard to give a trawl the same spread. To assist in solving common rigging faults and otterboard problems. To provide guidance on the possibilities of saving fuel.

Turbot Hatchery Production 1982

During 1982 the Ardtoe Hatchery of the Sea Fish Industry Authority transferred over 59,000 young fish to the weaning unit, the greatest number of turbot produced at Ardtoe in a single year. However, the season was marked by consistently low larval survivals, the high production being achieved by greatly increasing the number of batches handled (73 batches in 1982, 39 in 1981, 27 in 1980). A total of 1,472,000 larvae were stocked producing a survival of 78,600 (5.3%) at day twenty (d20) and 59,000 (4.0%) on transfer to weaning tanks. The survival to weaning compares with 5.3% in 1981 and 13% in 1980. There was a reduced dependence on eggs from other units in 1982, 54% of day one (d1) originating at Ardtoe compared with 18% in 1981 and 38% in 1980. There were also indications, for the first time, that larvae from Ardtoe produced eggs exhibited better eventual survival than those from other sources.
