Ecosystem Approach to Fisheries Management works—How switching from mobile to static fishing gear improves populations of fished and non?fished species inside a marine?protected area

Designated using a Statutory Instrument in 2008, Lyme Bay marine-protected area (MPA) is the UK's first and largest example of an ambitious, whole-site approach to management, recover protect reef biodiversity. The applies consistent this case excluding bottom towed fishing, across full 206 km2 extent MPA, thus protecting mosaic reef-associated habitats from regular damage, while still allowing less destructive fishing methods, such as static gear, rod line, diving. To assess effectiveness management strategy for mobile taxa sustainability those that continue be targeted, Exploited Non-Exploited species' populations were compared inside relative open control sites spanning 11 12 years designation. baited remote underwater video systems (BRUVs) deployed annually benthic demersal fauna. Overall, number significantly increased MPA controls total abundance both treatments. fish showed increases (430%) (370%) over years. Likewise, but lesser degree controls, commercially time, potentially showing ‘spillover’ effects MPA. did not show changes. Regardless constituting majority fishery value, highly valuable invertebrates no significant changes time. Synthesis applications. shows importance whole site, comprising mosaics different habitats, through protection sessile organisms contribute essential habitats. This Ecosystem Approach Fisheries Management can benefit maintain sustainable fisheries species conservation importance.
