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.

Aim:
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.

Team 2: Beam trawl survey of the north Thames estuary 7th-9th September. Push net sites sampled throughout the period 1st-23rd 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. 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.
