4. Finfish by-catch in the krill fishery for the 2010 and 2011 seasons

   -catch. This paper uses data collected using the fish sampling protocol (K12) during 2010 and 2011 in ... order to estimate finfish by-catch in the krill fishery. The information regarding by-catch of finfish ... in the krill fishery is limited and 2010 was the first year when the simplified sub-sampling method ... was used.  With more data from the upcoming season and greater observer coverage across the fishing ...

5. An integrated assessment model for Antarctic krill: progress update

   under development for Antarctic krill are compared to estimates from CMIX and TrawlCI using the same net ... trawl data. The different configurations of the integrated model were varied based on whether acoustic ... data or net densities were used as model inputs for the biomass data, on how the biomass data were ... whether a narrow or wide version of the age-length transition matrix was used. The biomass data calculated ...

6. 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 ... fishery: human consumption, krill meal and frozen krill. When considered separately for different ...
