Objectives1. To carry out a plankton survey using the 53 cm High Speed Tow Net fitted with a MAFF Guideline CTD monitoring system, to determine the distribution and abundance of crab (Cancer pagarus) larvae.
2. To take sub-surface sea water samples for salinity determination at each plankton station and to monitor continuously sub-surface sea water for chlorophyll 'a' fluorescence.
3. To use a fine-mesh auxilliary sampler at selected stations to determine the distribution of scallop (Pecten maximus).
4. To take additional plankton samples in areas of highest abundance of larvae to estimate haul to haul spatial variability.
5. To deploy baited crab pots in selected areas of the English Channel to monitor the good condition of female crabs.
6. To study the vertical distribution of crab larvae using a LHPR sampler.
7. To deploy an ARGOS satellite tracked drifting buoy to track the drift of crab larvae in the La Chapelle Bank area.
8. To sample for sole (Solea solea) eggs and larvae at selected stations if time allows.
There was insufficient time to complete aim 6.
