Trawling generally catches toothfish in the smaller size range, which requires calculations to be made at the annual stock assessment meetings of CCAMLR to take these catches of smaller-sized fish into account, and lowers the overall available catch of toothfish by trawl.
Depending on the market, the fish may also be filleted or simply gutted.
