Differentiated catchability of trawls as a method for a more precise estimate of density of krill swarms and its biomass
considerable importance for catching results. It is proved that the estimation of density and size structure of ... fished krill swarms should be performed on the based of differentiated catchability of krill trawls. A ... mathematical model of krill trawling has been developed for estimating the above values. Author(s): V. Akishin ...

Heart rate and behaviour of fur seals: implications for measurement of field energetics
Abstract: Archival data loggers were used to collect information about depth, swimming speed, and heart rate in 23 free-ranging antarctic fur seals. Deployments averaged 9.6 ± 5.6 days (SD) and totaled 191 days of recording. Heart rate averaged 108.7 ± 17.7 beats/min (SD) but varied from 83 to 145
