PurposeResearch
ObjectivesJoint survey between: FV Alvic, FV Avon Valley, FV Challenge, FV Jo's Boys, FV Our Tracey, FV Sharowna, FV St Richard and Wash Harvester.

Aims:
1. To carry out an inshore beam trawl and pushnet survey of part of the North Sea and English Channel coasts, of young demersal fish in relation to the environment. To include collecting data for juvenile flatfish year-class size estimation.
2. To continue studies of growth and mortality of young sole in the area off Lowestoft and in Rye Bay.

Team 1: Beam trawl survey of the Rye Harbour to Pevensey Bay area 6th-9th September. Push net sites sampled throughout 1st-19th September.

Team 4: no ship listed. Departed from Bridlington to sample push net sites between the Wash and Berwick during 1st-10th September.

Results:
1. In total throughout the survey 320 hauls using the 2m beam trawl and 61 push net sites using the standard 1.5m push net sampled. 11 additional hauls made. All fish caught identified and measured. Surface salinity, temperature, sediment samples and benthos obervations made at each station. Shrimp by-catch recorded at each station. Observations of dissolved oxygen levels made at most stations in the Thames estuary and at all stations in the River Thames. Samples of plaice taken for age determination studies.

2. Lowestoft and Rye Bay. Survey of the distribution and abundance of 0-group sole completed. Live 0-group sole held in tanks for 24 hours then deep frozen.

3. Samples of 0-group plaice collected. O-group plaice caught in Bridlington Bay area were heavily infested with Rhipidocotyle sp. Samples from nephrops catches of other vessels processed.
