To increase knowledge of the spatial and temporal dynamics of spurdog in
waters off North Wales, to provide contemporary data on the reproductive
parameters used in demographic models, and to increase understanding of the
discard survival of fish caught under commercial conditions.

Studies focused on spurdog taken by longliners operating in the Irish Sea.
This fleet of small, inshore vessels is based primarily in Holyhead (North
Wales), and the study was undertaken on a potter/liner *Sarah H.*
Three surveys took place. Some of the spurdog were tagged with Petersen discs
and released after biological information was recorded, including sex, length
and a qualitative index of health state (1, lively; 2, sluggish). This will
allow the longer term survival of discarded fish to be examined. The remaining
parts of the catch were measured, and a subsample of females was dissected to
collect information on the reproductive biology. Given that longlining for
spurdog can result in large catches, it was not always possible to quantify
catches completely, but large catches were subsampled and raising factors
estimated.
