This survey was carried out between June-July 1989 in the English Channel and
the Bay of Biscay in order to investigate the distribution and abundance of
crab (Cancer pagurus) larvae. A fine mesh sampler was also used to
determine the distribution of scallop (Pecten maximus) larvae and to take
additional plankton samples in areas of highest abundance of larvae to
estimate haul to haul spatial variability. 319 stations were sampled on the
main survey grid. This data consists of the numbers of crab larvae, plus fish
eggs from a selected few stations, along with associated positional data and
volumes filtered.
