By-catch in the Australian fisheries in Division 58.5.2
Abstract: This paper presents bycatch information for the Australian fisheries in Divisions ... 58.5.2 for the 2003/2004 and 2004/2005 seasons. Bycatch in the trawl fisheries was low, generally less ... than 1% of the total catch (target plus bycatch). Higher percentage bycatch rates occurred in trawling ... grounds where the fishing effort and therefore target catch was low. Bycatch in the longline fisheries was ...

Investigation of potential biases in the assessment of Antarctic toothfish in the Ross Sea fishery using outputs from a spatially explicit operating model
. Conceptually this assumption implies either that tagged and untagged fish mix equally in the population, or ... that fishing effort for recaptures is distributed in proportion to the underlying abundance. Neither of ... these conditions are likely to occur in practice, and violation of this assumption may lead to bias. In ... this paper we investigate such potential biases in the assessment of Antarctic toothfish in the Ross ...
