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
differences between our estimates and others can be explained by a number of factors such as: an ... population, and the overestimation of the demand for krill by predators. Even if these low global krill ... the old target strength which has effectively underestimated the krill biomass by a factor of three so ...
