§ Mr. Matthew TaylorTo ask the Secretary of State for Scotland what protection there is for marine animals in United Kingdom coastal waters against the adverse effects of underwater sonic repellants employed by fish farmers in Scotland. [29842]
§ Sir Hector MonroSonic repellants have been brought into use as a non-lethal means of preventing predation of farmed fish. I am not aware of any evidence that they pose a threat to marine mammals which approach, but which then can retreat from, fish cages where such devices are in operation.
