| Description: | 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. This SEAwise report describes assessments of the impact of fishery on the benthic ecosystem using the Relative Benthic State (RBS) indicator for four case study areas (Baltic Sea, North sea, Western Waters, Eastern Mediterranean Sea). The RBS indicator determines the risk of fisheries impacting on the benthic habitat based on the fishery footprint (SAR, metier specific depletion) and the sensitivity of the habitat (longevity composition). First assessments were reported in the previous deliverable of task 4.3 and here updates are added along with expected changes in response to management measures. In the updated model for the Danish EEZ in the Baltic and North Sea, the impact of hypoxia is included in the assessment. The Western waters has developed one integrated model for predicting the sensitivity of the habitats. For the Ionean Sea (Western and Eastern part), an integrated assessment is executed by expanding the models based on different data sources (macrofauna versus epifauna). The model-based assessment results of benthic impact offer valuable support for evaluating fisheries management measures and their effect on the assessment outcome. The types of fishery management scenarios investigated were: (1) change in fishering effort within the area; (2) spatial restrictions to fishery and/or related effort displacement. The aim is to evaluate benefits to RBS of effort or spatial restriction fishery management scenario and several case study area specific scenarios were tested. Most scenarios focused on spatial restrictions, based on actual, planned or theoretical MPA placement, sometimes combined with decreasing effort (no displacement considered). The MPA scenarios are tested at different scales (entire area, ices subareas, member state EEZ, certain habitats). These spatial scenarios have a very small effect on the mean RBS value in most ... |
