1991 - 1991 Centre for Environment, Fisheries & Aquaculture Science (Cefas) North Sea / English Channel Plankton Survey - RV Corystes 04/1991

Plankton data from Corystes 04/1991 as part of a series of 4 plankton surveys carried out in the North Sea and English Channel between 20th March - 28th June 1991. The aims were to study: - The distribution, abundance and production of sole ( - *Solea solea* - ) eggs as part of the ICES coordinated programme to estimate the female sole spawning stock biomass in divisions IVb, c, d, e. - The distribution and abundance of the planktonic stages of crab ( - *Cancer pagarus* - ), spider crab ( - *Maia squinado* - ) and bass ( - *Dicentrarchus labrax* - ). - The vertical distribution of crab larvae using the LHPR system. Plankton samples were collected at each site on a planned survey grid. This data consists of the numbers of fish eggs and larvae, along with associated positional data and volumes filtered, of the main net samples. It does not include the LHPR samples.
