Integrated analysis of the by-catch data in the Ross Sea toothfish fishery
Abstract: The indices of exploratory toothfish fishery in the Ross Sea for the period of 2008 ... -2015 are considered. The analysis was focused on CPUE toothfish (kg/1000 hooks), by-catch CPUE (kg/1000 ... hooks) and normalized target catch ratio. There was evidence of distinct differences in the mean (and ... distribution) in the CPUE toothfish and the by-catch CPUE. Our analysis also show that target catch ratios ...
