A krill–predator–fishery model for evaluating candidate management procedures
simulations. We present a range of performance measures that can be used to evaluate catch-allocation ... well as fishery performance. This evaluation must be conducted in the context of considerable ... transport of krill between these areas. Krill and predator population dynamics are implemented with coupled ... uncertainty, and structural uncertainty can be assessed by comparing and merging results from multiple such ...

TARGET STRENGTH STUDIES ON ANTARCTIC SILVERFISH (PLEURAGRAMMA ANTARCTICUM) IN THE ROSS SEA
Abstract: Target strength (TS) determinations can be classified into several types: 1 ... free swimming fish in their natural habitat. A canvassing of the literature suggested that the type of ... study may influence the result. For example, some authors suggested that freezing the fish reduce the ... over-all backscatter of 30% (Sun et al. 1985), others that TS measurements on living fish ex situ would ...
