Sažetak
Bluefin tuna farming, as a capture-based aquaculture activity, where fish captured mainly by purse seines are transferred into rearing cages for growing purposes, created a problem in collection of accurate catch-at-size data, having negative effect on quality of ICCAT Task 2 statistics. Use of stereoscopic camera system has been proposed as a possible solution to overcome this problem (ICCAT Rec. 12-03), as a tool that can improve quality and accuracy of Task 1 catch data and Task 2 size data, and therefore contribute to collection of catch-at-size data needed for bluefin tuna stock assessment. Some of first experiences of using stereoscopic camera system at Croatian bluefin tuna farms are described in this paper.
