A modified version of Jones’ length-based cohort analysis is linked to economic data from the Swedish trawl fishery for Norway lobster (Nephrops norvegicus). The current regulation implies a fishing practice where each landed lobster entails three killed due to discard mortality and different cases of trawl selectivity are compared together with varying natural mortality.

In this paper we analyse the possibility of an incentive-based (IB) environmental regulation of domestic civil aviation in Sweden.

This article discusses bioeconomic analysis and different management strategies in fisheries. It reviews recent developments, which show the need to expand the analysis to multispecies fisheries and management.
