Spatial distribution of predator/prey interactions in the Scotia Sea: implications for measuring predator/fisheries overlap
conditions that produce high concentrations of krill associated with those islands produce a system in which ... the CCAMLR 2000 krill survey were used to identify the areas of potential overlap with fisheries in ... the Scotia Sea and to determine the scale at which such overlap should be measured. The relationship ... had a characteristic scale of c 200 km and the relationship with distance from land showed a log ...
