3. Semi-empirical acoustic estimates of krill biomass derived from simulated commercial fishery data based on single-frequency acoustics

   fishing seasons. From these data we develop semi-empirical indices of acoustic biomass in a Generalized ... Linear Modeling framework. We correlate these estimates of biomass with acoustic estimates derived from ... Elephant Island and West Shelf Areas of the US AMLR survey grid. Cross-validation of acoustic estimates ... frequency of animals is skewed towards larger animals. We show that it is possible to develop semi-empirical ...
