   / Description:  This paper describes the results of fishing a single krill aggregation with a commercial trawl ... trawl catches krill length composition hardly varied at all. Statistical analysis of catches showed that ... , estimates of krill length based on data obtained using either commercial or research trawls will be biased ... than that obtained with the IKMT research trawl data. For the maximum observed difference in krill ... difference between mean krill lengths in catches that one could consider to be random. The research trawl ... catchability resulting from its reduced trawl-mouth height (Kasatkina, 1991). It should be recalled that ... numerical density and abundance (Table 4). It must be pointed out that the selectivity properties of a ...
