PurposeResearch
ObjectivesThe cruise was the first of five plankton surveys in 2010 to estimate the Spawning Stock Biomass (SSB) of plaice, cod and haddock in the Irish Sea by the Annual Egg Production Method (AEPM). These cruise are basically a repeat of a similar series of surveys conducted in 2008.

In addition to plankton sampling at 106 pre-selected stations, trawling was conducted (when time and conditions allowed) to collect samples of mature cod ovaries for fecundity estimation.
