Analysis of longline fleet operation on the Patagonian toothfish (Dissostichus eleginoides) in the subarea of the South Georgia Island (48.3) in 1989–2003

The main characteristics of Patagonian toothfish (Dissostichus eleginoides) catch dynamics off the South Georgia Island and Shag Rocks (sub-area 48.3) for the 1989-2003 period are given. Taken the intensity of fleet operation as an example in the sub-area, it was confirmed a decrease in catches both for 1000 hooks and vessel/day. The given objective long-term data evidenced a substantial decrease in catch per unit value and necessity of the more attentive approach to the assessment of the state of the toothfish population in this area of traditional fishing and more precautionary approach to the TAC.
