North Sea Cod Spawning - Plankton Survey

Ichthyoplankton data from a survey carried out by RV Corystes as part of an internationally co-ordinated series of surveys to assess the cod and plaice spawning areas in the North Sea, organised by the Planning Group on North Sea Cod and Plaice Egg Surveys (PGEGGS). The data consists of the numbers of fish eggs and larvae identified at each sampling site, along with associated positional data and volumes filtered.
