SEAwise Report on effects of environmental and ecological factors on stock productivity for online tool

The SEAwise project works to deliver a fully operational tool that will allow fishers, managers, and policy makers to easily apply Ecosystem Based Fisheries Management (EBFM) in their fisheries. This SEAwise report aims to synthesise the results of population dynamic modelling tools used in a single species mode to demonstrate the effect of integrating the impact of environmental drivers on our perception of stock productivity, as well as the effect of different environmental scenarios, all other things being equal. At this stage, the stocks of interest have been parametrised in the different modelling tools (FLBEIA, BEMTOOL, BEE, SMS) and for each of them a baseline scenario, in which the productivity of the stock (weight/length at age, maturity and natural mortality) and the exploitation pattern (selectivity, discards) remain aligned to the stock assessment has been parametrized and run.

Overall, the baseline runs presented here are considered to be realistic and consistent with perception of long-term stock productivity under current management and reference points. However, several stocks are currently in a benchmarking process and the baseline simulations conducted under this task will be updated in the future.
