Abstract :Today, with global warming, problems occur arising from the deterioration of ecological balances in all seas of the world. These unexpected events affect the fishing industry quite negatively. As a matter of fact, the emergence of jelly organisms that covered the sea surface by about 80% during the hunting season in the Marmara sea in 2007, damaged both hunting equipment and caused a significant product loss. Thats why many fishermen could not go hunting, lost their nets, waste their fuel, labor, food, etc. Musilage was partially reappeared on the shores of Balıkesir in 2020 and caused great discomfort in the related circles. This study, which was carried out in order to estimate the economic losses that may occur in the event that the musilage re-occurs in 2007, has been carried out in the light of real data. The main material of the research consists of the data obtained from the Ministry of Food, Agriculture and Livestock and General Directorate of Agricultural Research and Policies. In the study, the economic losses that may occur in the event that these organisms reappear in the future are calculated by using proportional calculations of the losses caused by the jelly organisms that occurred in the past in the Marmara Sea,. As a result of the research; it was determined that the fishermen who went fishing during the musilage lost an average of 14123 Euros due to the loss of the product as well as the various expenses they made due to sailing throughout the season. In the study, it was calculated that the decrease in fishing income was 27459 Euros / year on average, and the effect on fishing income was -61.41%.
