Course Contents
In this course, general biology and fattening process of bluefin tuna, and other tuna fish species will be described in detail, and also live-catching, towing, adaptation and feeding protocols will be displayed clearly. In addition, it could be demonstrated net-cage structure, mooring systems, fattening period, broodstock management, stress factors, and harvesting techniques, and also it will be argued about the importance of bluefin tuna quotas and their future perspectives for the sustainable fattening system.
