A note on relating krill CPUE measures to abundance trends
Abstract: A crude mathematical framework is developed to describe krill abundance in terms of ... selected parameters of various aggregation behaviours exhibited by krill (Euphausia superba Dana). The ... relationship of combinations of these parameters to various possible measures of catch-per-unit-effort (CPUE ... ) for the Antarctic krill fishery is considered. The combined index of catch-per-hour of trawling ...
