Irish Sea Plankton Survey - RV Clione 11/86

A survey was carried out between September-October 1986 by the Centre for Environment, Fisheries and Aquaculture Science in order to investigate the distribution and abundance of yolk sac herring larvae on the spawning grounds east of the Isle of Man. Plankton samples were collected at each site on a planned survey grid. This data consists of the numbers of herring (and other fish species) larvae.
