The project was initiated in March 1987, as a collaborative study between the Fisheries Laboratory, Lowestoft and the NERC Institute for Marine Environmental Research (which became the Plymouth Marine Laboratory in 1988). The scientific problem studied concerned the differences that occur in fish yields per unit area between the Irish and North Seas; the Irish Sea has consistently yielded a lower catch per unit area than the North Sea. The aim was to study the productivity of both phytoplankton and zooplankton, in relation to the survival of fish larvae, and to investigate how differences in ecosystem structure might influence the availability of food and successful recruitment of fish, and to determine if these were critical factors which might explain the differences between these two seas.
