FSP Whelk Maturity Study

Abstract

The fishing vessels *Tomkat of Selsey* and *Beachy Head* were chartered in September 2009 to carry out two potting surveys in the whelk (*Buccinum undatum*) fisheries in two areas off the Sussex coast in the eastern English Channel as part of the Fisheries Science Partnership programme 2009/10. The main objective was to investigate the population structure of whelks spread throughout the two survey areas, one off Selsey (West Sussex) and the other off Eastbourne (East Sussex). Additionally, samples of whelks were collected and a sampling programme initiated to determine various aspects of whelk reproductive cycle. Data are size distributions of whelks and estimates of catch numbers by station, station details and morphometric data with assignment of sexual maturity for individual whelks.

Quality and validity

Lineage

Catch rates of whelks on both surveys were generally low and although typical for the time of year in which the surveys were undertaken, are atypical of those that could be expected at the peak of the season.
