Course Contents
In contents of the lesson below subjects are covered, the large pelagics (tunas, bonitos, swordfishes, etc.), which are the most important target fish groups in the Mediterranean is also catch in Turkish waters densely. This fishery is carried out by purse-seining, longlining, harpooning, handlining, fish trapping and gillnetting. The theoretical section of the lesson covers the identification and total landings and fishing techniques of the large pelagics in the Mediterranean and Turkey, biology and ecology of these fishes, history of the fishing and and also management strategies will be discussed comprehensively
