Simulation trial to explore the impacts of the Landings Obligation. The landing obligation will introduce a number of challenges to commercial fishing fleets particularly in the demersal mixed fisheries fleet segment. The impacts of the landing obligation are difficult to predict, but are likely to be metier and business specific. Key challenges will include requirements to land non-marketable undersize or over quota fish, cessation of fishing activity once the quota for the first individual TAC species is exhausted and costs associated with handling and disposal of non-marketable fish. In order to assess potential impacts, BIM intend carrying out trials to simulate the full introduction of the Landings Obligation. Vessels will be required to retain and land the species specified in Article 15.1.C(ii) of EU regulation 1380/2013, namely cod, haddock, whiting, saithe, Norway lobster, hake, common sole and plaice. An additional scientific quota will be used to cover any landings over quota and such landings will be sold with the profits recouped towards the cost of running the project.
