|Port of departure||Lowestoft, United Kingdom|
|Port of return||Belfast, United Kingdom|
|Objectives||The cruise was the first of five plankton surveys in 2008 to estimate the Spawning Stock Biomass (SSB) of plaice, cod and haddock in the Irish Sea by the Annual Egg Production Method (AEPM).
In addition to plankton sampling at 105 pre-selected stations, trawling was conducted (when time and conditions allowed) to collect samples of mature female ovaries for fecundity estimation.
