Relative selectivity of four sampling methods using traps and trawls for male snow crabs (Chionoecetes opilio)
Abstract: Catch rate and catch composition of male snow crabs were compared for four sampling methods. These methods were: (1) large-meshed commercial traps, (2) small-meshed traps, (3) bottom trawl deployed during the day. and (4) bottom trawl deployed at night. Catches were characterized in

Tooth growth in male Antarctic fur seals (Arctocephalus gazella) from South Georgia: an indicator of long-term growth history
Abstract: Growth of upper canine teeth of male Antarctic fur seals (Arctocephalus gazella) which died of natural causes at Bird Island. South Georgia, was quantified from measurements of annual layers in longitudinal sections of teeth. Mean age at death was 7∙69 ± 0∙07 years and this showed a

Can we use discriminant function analysis to sex penguins prior to calculating an index of a morphometric parameter?
Abstract: In sexually dimorphic species, morphometric parameters have separate distributions for males and females, and these often overlap. Whilst discriminant analysis can be used to determine the sex of individuals, it is only able to correctly sex a certain proportion of birds. Two overlapping

Status of krill target strength
Abstract: Empirical estimates for the target strength of krill are extracted from the literature. These are confined to measurements on aggregations of live euphausiids, which should avoid a frequent cause of bias in single-animal measurements, namely thresholding. Theoretical estimates for the

Data on krill, Euphausia superba Dana, consumption by coastal fishes in Division 58.4.2 (Kosmonavtov and Sodruzhestva Seas)
Abstract: Basing on the materials of complex study of the Kosmonavtov and Sodruzhestva Seas ecosystems, draft calculations were done to determine the E.superba consumption by near-bottom- pelagic fishes as its main consumers in the above areas. According to the data of trawlings in the depth range
