论文部分内容阅读
Sea ranching of the great scallop (Pecten maximus) in Norway is done by release of hatchery-reared spat to the seabed.The release areas are bordered by fences to prevent predatory crabs (Cancerpagurus) access to the scallops (Figure 1).A fence (50 cm high) of solid plates or plastic canvas is shown to be sufficiently efficient to obtain high scallop survival.Scallop sea-ranching is regulated under the Norwegian Aquaculture Act where measures are set to contribute to a sustainable development of the industry.The Institute of Marine Research aims to provide scientific knowledge on ecological effects from scallop sea ranching.Using fences on the seabed to prevent a target predator access to the area may also obstruct other mobile fauna, and the fence combined with high scallop density within the farmed area may influence the benthic fauna composition.It is also questioned whether increased biodeposition of organic matter by the farmed scallops may affect the benthic environment.
