"The main aim of this cooperation is to develop precise target strength- body length relationships for whitefish (Coregonus lavaretus), and cyprinids such as roach (Rutilus rutilus) and bream (Abramis brama) observed vertically with 38 kHz and 120 kHz frequency, the latter for whitefish only. Target strength will be measured by the single target detector in controlled net cage experiments. Fish of different size groups will be placed into the cage and their acoustical size (TS) will be measured. The dependence of target strength on the depth of fish in the water column and their orientation will be also observed. The minimum fish size for the use of 38 kHz will be determined."@en . . .
