Crab (Cancer pagurus) maturity studies

Abstract

Morphometrics and maturity parameters for brown crab ( *Cancer pagurus* ) in the English Channel and North Sea (Newlyn, Brixham, Selsey and North Norfolk). Combination of parameters describing the reproductive state of dissected crabs collected as part of a project aimed at determining the seasonality of the reproductive cycle and the size at sexual maturity.

Lineage

Samples of crabs were sourced from commercial fishers from three areas in the English Channel and off the Norfolk coast. Because the samples were taken by baited traps, consideration needs to be given when analysing these data. A few records may be for crabs taken on an * ad hoc* basis elsewhere. Some of the data fields are indexed and to make use of this dataset the user will require the maturity keys linked in the relevant documents section. The user will be responsible for assigning sexual maturity to each record based on appropriate features of the gonads or other factors. How Cefas have assigned maturity state is outlined in a working document also linked.
