THE RISK TO FISHERY PERFORMANCE ASSOCIATED WITH SPATIALLY RESOLVED MANAGEMENT OF ANTARCTIC KRILL (EUPHAUSIA SUPERBA) HARVESTING
will affect fishery performance. One metric of potential performance is the probability of encountering ... exploitable densities of the target species at the scale of fishing operations. The probability of ... encountering exploitable densities of Antarctic krill, Euphausia superba, at the 1 nm scale during an acoustic ... spatial scale of management units could usefully predict effects at the scale of fishing operations ...
