Abstract: The relationship between krill abundance and predator performance is fundamental to an ... ecosystem based approach to resource management. We propose a method using krill sampled from the diet of ... predators to provide a length-frequency distribution of krill at times when it is possible to run automated ... operations. This will allow a robust estimate of krill abundance to be estimated from acoustic data. Changes ...
