Description 
Summary

A series of 11 plankton surveys aimed at providing an independent assessment of the size of the spawning stocks of cod, plaice and sole in the Irish Sea. 3 other labs participated : dept of the marine, Dublin; DANI, Belfast; Port Erin Marine Lab, Isle of Man. 4 grids were sampled by CEFAS - 5 sets of samples were analysed. Each grid consisted of 90-106 samples; fish eggs, fish larvae and Nephrops larvae were sorted and identified. Cod plaice sole eggs were staged, as were nephrops larvae.
