The scientific advice on management of fisheries is primarily aiming at avoiding overfishing of the fish and shellfish stocks and does only to a very limited extend address how the utilisation of the resources can be optimised within the framework of sustainable ecosystems. An example is the regulation of the demersal trawl fisheries in the Skagerrak and the Kattegat which to protect the cod stock is sub optimal in relation to an optimal utilisation of the Norway lobster (nephrops) stocks. The project takes a new approach to the management and aims at optimising the utilisation af nephrops stocks in trawl fishery without compromising the protection of cod.

The nephrops fishery is one of the economical most important fisheries in Denmark. In the Kattegat and Skagerrak nephrops catches accounted in 2010 for 53 % and 25 % respectively of the total value of fish and shellfish landed by Danish fishermen while cod landing accounted for 2 % respectively 17 %. Cod is taken as bycatch in the nephrops fishery and it has been necessary to introduce measures to limit the bycatches of cod. These measures have, however, a negative impact on the nephrops catches.

The project includes four work packets:
(i) development of advice on the fishing mortality for the nephrops stocks that is consistent with maximum sustainable yield;
(ii) mapping of the distribution of nephrops in Skagerrak and Kattegat;
(iii) development of a new trawl concept optimising the catchability on nephrops while limiting the bycatches of cod and the impact on the sea bed;
(iv) evaluating alternative fishing methods for nephrops including fishing with pots.

The project is coordinated by DTU Aqua.
