| Anmärkningar | Sampling was done via beam trawling. From January 2006 to April 2007, six 10-minute trawls were conducted every month. All of the catch were collected for identification and processing. After each sampling, the next trawl was done in the opposite direction beside the previously trawled path. | ||
