To carry out an inshore beam trawl survey to estimate juvenile flatfish abundance and collect data on small demersal fish in relation to the environment, in support of the EU Data Collection Regulation. Method Two teams of two staff working on charter vessels carried out the Young Fish Survey. The standard survey positions for each of the two areas were worked using a 2-metre wooden beam trawl with three tickler chains a 4 mm-mesh liner towed for ten minutes. At each station all the fish were identified and measured, the shrimp catch estimated volumetrically and other commercial shellfish species counted. Benthic species were counted at 20 of the standard positions for each survey area that were pre-selected prior to the survey's commencement. Otoliths were collected for ageing purposes from sole and plaice. Observations of temperature and salinity were also recorded at every station and dissolved oxygen readings were taken in the River Humber for the Environment Agency. Narrative Staff departed Lowestoft on the 25th August to drive to Colchester prior to the commencement of the survey the following day aboard the FV Fisher Lassie, which set sail from West Mersea. Over the course of the next four days, 42 stations were sampled, including 10 stations with full benthos counts. One net was damaged during the course of the northern Thames survey. Staff drove to Whitstable on 30th August and loaded sampling equipment onboard the FV Columbine. The southern Thames part of the survey commenced on 31st August and over the course of the next three days, 37 stations were sampled, including 10 stations with full benthos counts. One of the survey stations at Mid Shoebury was not fished due to time constraints resulting from inclement weather on the first day. The survey was completed on 2nd September after which staff returned to Lowestoft the same day. Two nets were damaged during the course of the southern Thames survey. The survey was completed without incident, with no major problems to report. |
