Ecosystem-based fisheries management (EBFM) of Western Rock Lobster: taking account of climate change effects
In Australia, the ecosystem approach to fisheries (EAF) identified two factors influenced by climate change that impact the fish/lobster production. Rising water temperatures had effects on the timing of egg development, including from deposition to hatching, while increased winter storms affected larval settlement. Other effects included changes in the size of migrating lobster, size at maturity and their growth. In order to have adaptation measures in place that led to some new management interventions based on the ecosystem approach to fisheries, it was crucial to monitor some of the environmental factors affecting fish/lobster production together with egg production and level of settlement. Furthermore, it was necessary to establish some harvesting strategies that were responsive to the monitored changes. The introduced management intervention was able to reduce fishing activities while at the same time increasing fish egg production. This had a positive effect on economics of the commercial fishery and social wellbeing of the recreational fishing communities.
