Özet

This study was carried out at Anamur district of Mersin province using trawl net to determine marketable and discarded part of the catch of species. Catch samples were taken during September 2004 and April 2005 at fortnight intervals. Totally 923.17 kg species were caught during the period September 2004 - April 2005, which consisted of 406.9 kg target species, 409.1 kg catch species and 107.17 kg discard species. It was observed that weight share of target species from the total catch was 37.81 %, share of bycatch 51.36% and share of discard, fish 10.63%. Significant relationship (p<0.05) was recorded between bycatch and discarded fish, target species and bycatch, and target species add discarded fish in terms of weight.
