Experimental trips by SFA’s research vessel were undertaken in 1994 and commercial trips started in 1995. The total landing catch increased from 215 mt in 1996 to 456 mt in 1999. The estimated catch rates varied from 0.64 kg/hook in 1996 to 0.92 kg/hook in 1999. Loss of catch due to predation by marine mammals (pseudorca crassidens) remains one of the major problem of this fishery. In 1999, 24 % of the total catch (109 mt of fish) was lost due to predation.
