Estimates of global krill abundance based on recent acoustic density measurements and their implications for the calculation of precautionary catch limits and the designation of management areas
Abstract: The global abundance of krill is estimated using recent estimates of krill density from ... acoustic surveys and historical information on the overall range of krill. The biomass estimates fall ... between 64 and 137 million tonnes- at the low end of values that have been suggested in the past. The ... underestimation of the range, or of the acoustic biomass estimates, the possibility of a large, undetected krill ...

Using outputs from spatial population models of Antarctic toothfish in the Ross Sea region to investigate potential biases in the single population model
Abstract: We present a method to evaluate potential biases and uncertainty in the tagging ... assumptions of the stock assessment for Antarctic toothfish in the Ross Sea region using spatially explicit ... operating models. The method allows investigation of potential biases and uncertainty in the assumptions of ... spatial distribution and fish mixing used in the standard stock assessments for the Ross Sea region (and ...

An updated spatially explicit population dynamics operating model for Antarctic toothfish in the habitable depths of the Ross Sea region
model for Antarctic toothfish in the Ross Sea region, for a medium scale spatial resolution (189 spatial ... cells) covering the Ross Sea region. We build on the previous working medium-scale model in which the ... habitat for toothfish (120 cells – semi-restricted model). Model fits to the reproductive data were ... unsatisfactory in previous models, with a much flatter maturity ogive than that derived through histology. In the ...
