4. Counts of surface-nesting seabirds breeding at Prince Edward Island, summer 2001/02

   Abstract:  The first midsummer survey of surface-nesting seabirds at Prince Edward Island was ... conducted during December 2001. It was also the first census for most species since the early 1980s. Despite ... concerns about the impacts of longline fishing mortality on various albatrosses and giant petrels, there ... was no evidence that populations of these species had decreased. Indeed, the estimate of wandering ...

5. Different CPUE types in Soviet krill fishery statistics in 1977–1992

   Abstract:  The various CPUE indices used in Soviet krill fishery statistics and their main sources ... and primary data for their calculations were considered. The main CPUE indices were catch per fishing ... day (CFD), catch per extended fishing day (CEFD) and catch per hour (CH). The primary data for all the ... strategies and so hauls duration, mean daily CFD and CH are well correlated. Depending on the strategy ...

   Subarea 48.3 since 1977 but have never been fully assessed by the Working Group on Fish Stock Assessment ... because of a lack of reliable biological and catch data. This paper attempts to reconstruct the fishery ... for these two species by assuming that 75% of the ‘unidentified fish’ caught by the Soviet Union in ... the years 1977 to 1988 consisted of catches of C. aceratus and P. georgianus. Biological, age-length ...

10. Possibility of predicting sea-ice concentration (SIC) in research block (RB) 48.6-5 (Southern part of Subarea 48.6) using sea surface temperature (SST) in RB 48.6-2 (Northern part of 48.6)

    Abstract:  It  was  reported  at  WG-SAM-2019  that  the  sea  ice  concentration  (SIC) of RB ... 48.6-5 corresponded well with the dynamics of monthly sea surface temperature  (SST)  anomaly  in  RB ...   48.6-5.   However,  in  the  prediction  of SIC  in  RB  48.6-5  using  the  monthly  SST  anomaly ... , consequently there is very little information on the SIC during this period. However, the SST of RB 48.6-2 can ...
