A new fishing gear in the Chilean Patagonian toothfish fishery to minimise interactions with toothed whales with associated benefits to seabird conservation
Abstract: We describe a new fishing technique, called the Chilean system, adapted from an artisan ... fishery for Patagonian Toothfish. The artisan system was modified to include a net sleeve that is placed ... whales. In addition to this, each 15 m-long vertical line carry a weight at the end, this sinks baited ... hooks at up to 0.80 m/sec. This fast sink rate causes the line to sink immediately behind the vessel ...

A compilation of parameters for a krill–fishery–predator model of the Scotia Sea and Antarctic Peninsula
Abstract: We describe the compilation and derivation of parameters for use in krill-fishery ... -predator models of the Scotia Sea – Antarctic Peninsula region. The primary aim is to provide input for the ... model developed by Watters et al. (2006), which we use to define the required parameters. However, these ... parameters should be applicable to other models of the system. Our methods include the use of weighted ...
