Plankton samples were collected at each site on a planned survey grid. This data consists of the numbers of fish eggs and larvae, along with associated positional data and volumes filtered. A fine mesh (80 micron) 'PUP' sampler, attached to the frame of the Gulf VII sampler, was used to collect plankton samples for analysis of zooplankton species. These were analysed under Cefas contract C3576 and are recorded separately.

To measure, stage and preserve these eggs in ethanol prior to species identification using a DNA technique on return to the laboratory (CEFAS). **CORYSTES Cruise 06/2010:** All 106 stations were successfully sampled, giving complete coverage of strata A, B, C, D and E. In total 1178 gadoid like fish eggs in early development stages 1A & 1B, between 1.10 and 1.75mm diameter were removed and individually preserved in ethanol. A plankton sample and PUP sample were preserved at each station. **CORYSTES Cruise 15/2010:** All 106 stations were successfully sampled, giving complete coverage of strata A, B, C, D and E. In total 403 gadoid like fish eggs in early development stages 1A & 1B, between 1.10 and 1.75mm diameter were removed and individually preserved in ethanol. A plankton sample and PUP sample were preserved at each station. **CEFAS ENDEAVOUR Cruise 02/2010:** Plankton sampling with the Gulf VII began at 15:35h 20 January, at 53º 15'N, 04º 50'W. The plankton sampler was equipped with a Valeport CTD, a self-logging environmental package (ESM2 logger) and a fine 80μm mesh, ‘Pup’ sampler collected supplementary environmental data and biological samples at each station. 106 plankton stations were completed, covering the whole Irish Sea from 53º 00'N to 55º 00'N, with 270μm samples being collected on each station. The pup sampler or its flowmeter were not available on every station resulting in 93 samples being taken with the 80μm mesh net. Fish eggs in early development stages and between 1.1 and 1.75mm diameter were removed and individually preserved in ethanol. A total of 182 eggs were obtained during this cruise. **CEFAS ENDEAVOUR Cruise 05/2010:** 106 plankton stations were completed, covering the whole Irish Sea from 53º 00'N to 55º 00'N. Fish eggs in early development stages and between 1.1 and 1.75mm diameter were removed and individually preserved in ethanol). A total of 3997 eggs were obtained during this cruise. **CEFAS ENDEAVOUR Cruise 07/2010:** 106 plankton stations were completed, covering the whole Irish Sea from 53º 00'N to 55º 00'N. The pup sampler flowmeter worked well on this cruise resulting in 104 samples being taken with the 80μm mesh net. Fish eggs in early development stages and between 1.1 and 1.75mm diameter were removed and individually preserved in ethanol. A total of 537 eggs were obtained during this cruise.
