Özet

In this study, it was aimed to investigate the usage intensity and catching efficiency of deep water cast net for catching whiting (Merlangius merlangus) which is commonly used by small scale fishermen in summer and autumn seasons on the coast of Surmene town of Trabzon city, questionnaires were performed with 26 fishermen who used this gear in 2016 and 2017 fishing season of this gear. In addition, monthly sampling was carried out to determine the catching efficiency of this gear for 12 months in this region where deep water cast net is widely used. According to the statements made by the fishermen in the surveys, it was determined that fishermen are overboard in more than 50 days, consume more than 6 liters of fuel per fishing operation when they go to the sea and catch at least 1.2 +/- 0.1 kg fish per operation. In the experiment, 1.9 +/- 0.2 kg was calculated during the fishing season specified by fishermen. As a result of the study, it is clear that this fishing methods need to be investigated for the whole Black Sea coast.
