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 ... such as: an underestimation of the range, or of the acoustic biomass estimates, the possibility of a large, undetected krill ... population, and the overestimation of the demand for krill by predators.
