One of a series of 9 surveys in 1968 carried out by the Centre for
Environment, Fisheries and Aquaculture Science in the Southern Bight and
Borkum areas of the North Sea to investigate plaice larvae. Plankton samples
were collected at each site on a planned survey grid. This data consists of
the numbers of fish eggs and larvae and other zooplankton, along with
associated positional data and volumes filtered, from the main net samples.
