2. To include collecting data for juvenile flatfish year class size estimation.

Team 2: Beam trawl survey in the north Thames area 9th and 12th-13th September. Pushnet sites sampled throughout the period 5th-25th September.

Results:
1. In total throughout the survey 330 hauls using the standard 2m beam trawl and 43 pushnet sites using the standard 1.5m pushnet were sampled. All fish caught were identified and measured.
