The status of krill (Euphausia superba DANA) resources in CCAMLR Statistical Divisions 58.4.2 and 58.4.3 from 1988 to 1990. Results of acoustic surveys
Abstract / Description:
Since 1977 the YugNIRO Research Institute (Kerch, USSR) has carried out biological and ecological monitoring of krill resources in the central part of the Indian Ocean sector of the Antarctic (CCAMLR Statistical Divisions 58.4.2 and 58.4.3). Results of surveys conducted from 1988 to 1990 are discussed in the paper. It was found that the increase in krill biomass observed in the area in 1990 is linked with the abundant 1986 and 1987 year-classes and with a diminished rate of emigration of krill of these year-classes from the area in 1989/1990.
