The project has been carried out in collaboration between the Institute of Marine Research and SINTEF Fiskeri og havbruk AS.
Reduced profitability due to a large increase in fuel costs makes the project very interesting for the shrimp trawling industry.
The project was initially divided into three phases:
Phase I consisted of defining and preparing trawl concepts with the potential for at least a 25% reduction in resistance.
Phase II consisted of testing trawl concepts in a 1:10 scale in the test tank in Hirsthals and in a 1: 2 scale on board the F / F ""Catch"".
Based on these model experiments, a full-scale trawl was constructed in collaboration with shrimp fishermen in a reference group. FHF at Fiskarlaget's Service Office entered into an agreement on cooperation with Arctic Swan KS for the implementation of practical testing of full-scale trawl on board the M / Tr “Arctic Swan” in 2007. This testing constituted phase III of the project. The trawl was to be tested as a center trawl in a triple arrangement, and it was therefore necessary that all the trawls were more or less the same in order to be able to operate at the same time. M / Tr “Arctic Swan” uses shrimp trawls from Mørenot AS, and this producer was therefore selected to produce the new full-scale trawl.
When the results in phase III were not as expected and the new trawl concept was further modified, an additional phase was proposed in the project. Phase IV consists of testing the new modified trawl concept in full scale.
Goal: to develop a trawl concept for shrimp that reduces trawl resistance by a minimum of 25%, while maintaining the efficiency of shrimp.
Sub-goals for phase IV
To investigate and document the effect of the changes introduced after the last cruise.
