Tunas yield per recruit and MSY of longline fisheries, case of yellowfin stock in the eastern Pacific Ocean
Year: 2011
Type: report
Abstract: This paper discusses the conclusion of various IATTC stock \nassessment report on yellowfin that MSY of the longline fishery could be \nlarger than 400000 t. in the EPO. Based on the analysis of fishery data and \nenvironmental data in the Pacific ocean and in the EPO, the paper reaches \nthe conclusion that the real potential MSY of longliners on the EPO YFT \nstock is probably very low, for instance much lower than in the western \nPacific ocean. This low potential MSY is simply due to the fact that this \nresource is not significantly available to longliners, even if their yield per \nrecruit is high. This very low catchability of the EPO yellowfin stock to \nthe past and present longline fisheries is probably explained by the low \nrates of oxygen observed in this area at the traditional fishing depth of \nlongliners.
