On the possibility of practical utilisation of krill target strength TS in situ obtained on the basis of EK-500 measurements
Abstract: Comparative analysis of krill length distribution in the echosurvey area, obtained with trawl and acoustic methods is presented. Besides, the acoustic estimate of krill length composition was obtained on the basis of the empiric model by Greene et al. (1991) using estimates of target

Catchability of midwater trawls in relation to krill fishery
Abstract: The relation between mid-water trawl catchability and its construction, trawling regime, krill aggregations distribution in the study area is discussed. It is shown that while the trawl selectivity affects krill length composition in each trawl sample, the trawl catchability affects the

Some comments on the procedure of krill target strength assessment in echosurveys
Abstract: The impact of midwater trawl selectivity and catchability upon TS and TS 1 kg estimates in echosurveys is discussed. It is known that krill abundance and biomass estimation should be considered as two independent tasks with different requirements to midwater trawl utilization in

Foraging trip duration in male and female macaroni penguins at Bouvetøya
Abstract: The CEMP Standard Methods for monitoring foraging trip duration in Macaroni Penguins recommend using only males. However, males attend the chicks at the nest during most of the brooding period, while the females make frequent foraging trips. We analysed data from 17 males instrumented
