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 ... differences between our estimates and others can be explained by a number of factors such as: an ...
