2. Application of the bootstrap-method in assessment of target strength regression parameters on the basis of in situ measurements

   measurements with the fish size composition from trawl catches and should be accompanied with accuracy indices ... Abstract:  Target strength (TS) as a function of fish length (L) must be known to estimate fish ... density in acoustic survey. This TS-length function may be estimated by comparing in situ acoustic ... characterizing the uncertainty of its parameters. We show that the bootstrap–method is a highly efficient method ...
