Oyster reefs are biodiversity hotspots with multiple ecosystem functions and services that declining worldwide. Historic populations of European oysters ( Ostrea edulis ) have been decimated by overfishing nowadays considered functionally extinct in waters. To halt reverse the associated loss, oyster reef restoration was implemented into marine conservation measures several projects started across Europe. Following ecological standards, it is crucial to identify reef-associated predators predator-prey interactions influencing recovery as can control prey populations. Therefore, this study examined consumptive nonconsumptive among common North Sea predators, brown crabs Cancer pagurus lobsters Homarus gammarus ), on Helgoland island (German Bight, Sea) for first time. Field surveys monitorings offshore pilot experimental seafloor areas showed (i) crabs, co-occur these subtidal environments (ii) interact each other. Manipulative experiments indicated (iii, iv) both consume oysters, (v) medium-sized large safe from (vi) relatively lobsters. They also found (vii) presence mussels Mytilus spp.), an alternative more profitable prey, (viii) formation larger heavier clumps, difficult handle, reduce predation oysters. Furthermore, they (ix) crab conspecifics (x) natural abundances nonconsumptively limit consumption through intimidation mediated (xi) crab- (xii) lobster-released waterborne predator cues detected which indicates naturally underlying mechanisms regulating limiting Thereby, provides fundamental knowledge essential understand facilitate restoration.
