PurposeResearch
ObjectivesCombined survey using: FV Avon Valley, FV Challenger, FV Jo's Boys, FV Our Tracey, FV Sharowna, FV St Richard and FV Sundance.

Aims:
To carry out an inshore beam trawl and push net survey of part of the North Sea and English Channel coasts of young demersal fish in relation to the environment. Including collecting data for juvenile flatfish yearclass size estimation.

Team 1: Beam trawl survey of Selsey Bill to Swanage Bay area 13th-17th September. Push net sites sampled throughout 2nd - 18th September. Cooling water intake screens at Dungeness 'A' power station sampled on 4th and 20th September.

Results:
Throughout the whole survey a total of 303 valid hauls using the standard 2m beam trawl and 40 push net sites using the standard 1.5m push net were sampled. All fish caught were identified and measured. Surface salinity and sediment samples were collected and surface temperature and benthos observations were made at each station. Observations of shrimp by-catch were recorded at each station. Samples of plaice were obtained in each of the main area fished for age determination studies.

Samples of 0-group sole were collected.
