Application of the bootstrap-method in assessment of target strength regression parameters on the basis of in situ measurements
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 ... measurements with the fish size composition from trawl catches and should be accompanied with accuracy indices ...
