A note on relating krill CPUE measures to abundance trends
D.S. Butterworth and D.G.M. Miller (South Africa)
Resumen:
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 Read More

Some considerations on the usefulness of CPUE data from Japanese krill fishery in the Antarctic
Y. Shimadzu and T. Ichii (Japan)
Resumen:
The characteristics of Japanese krill fishery were reviewed in several examples based on the information recorded on log book. While searching behaviour seems to be the basis of this fishery, CPUE in terms of catch per minute of towing was thought to be an useful index of patch density and possibly of local abundance.

An updated information of the Japanese krill fishery in the Antarctic
Y. Shimadzu (Japan)
Resumen:
Annual summary of Japanese krill fishery in the Antarctic was updated with delineation of two different type of operation. Operated areas in 1983/84 and 1984/85 seasons were illustrated and three historical main fishing grounds were identified.

Some aspects of repeated operation on the same patch in Japanese krill fishery
T. Ichii (Japan)
Resumen:
Data of repeated operation recorded on Japanese log book were examined the validity of identifying the same patch and the resulting change in CPUE. While no change was detected in CPUE some difficulties were thought in identification of krill patch(es).
