Exploratory Fishing Trials for Buccinum undatum around the Island of Barra and South Uist in the Western Isles

Summary

This report presents the results of exploratory fishing trips undertaken between Sept 1996 and June 1997 to assess catch rates and composition of whelks (Buccinum undatum and Neptuna antiqua)in locations around the Western Isles. Buccinum was captured routinely at all loctions indicating a widespread occurrence throughout the two survey areas, whereas Neptuna was caught predominantly offshore, in deep water. However, the catch per effort was extremely low, and the areas investigated cannot be regarded as being able to support whelk fisheries. The predominance of animals with large and heavily fouled shells suggests the existence of an ageing population which, probably, would be unable to withstand sustained fishing effort. Furthermore, fishing opportunities would be severely restricted by potential conflict with other fisheries, in terms of seasonal access to grounds.
