Start year 2009 End year 2011 Funding (€) € 520,000 Website https://www.fhf.no/prosjekter/prosjektbasen/900221/ Summary The principle mechanisms in bottom trawl fishing have remained unchanged since the early 1900's. Higher oil prices and relatively low market prices on fish have motivated the fishing fleet to improve efficiency. In this project, we found that there are significant cost savings to be made by reducing the friction between the fishing equipment and the sea floor. This is achieved through the use of pelagic trawl doors instead of the normal bottom trawl doors. The pelagic trawl doors keep the trawl open sidewise as usual, and are also responsible for the height of the trawl's head rope. Along with a new trawl design and new trawl rigging, this has resulted in significant savings related to the operation and there are indications that catch levels are higher. Tweaks and testing was done on board the "M/S Roaldnes" (34 m) while targeting pollock, haddock and cod. The project has several partners who aimed to further develop the traditional bottom trawl to a more efficient and environmentally friendly fishing gear. The results related to the use of pelagic doors to pull the bottom trawl have been so successful that one expects that more vessels will adapt the method. Preliminary estimates indicate that the rigging reduced fuel consumption by up to 18% and costs related to gear maintenance were also lower (expected reduction ~ 40 %). The figures are based on experience from approximately 1 year of fishing with the new rigging and from records from the company's finance department. The project did also test a new trawl, developed by Vonion P/F. The trawl is the first bottom trawl constructed with a pelagic trawls upper half, meaning it has no own buoyancy. So far the experiences gained are positive and the trawl seems to increase catches compared to the traditional bottom trawl especially at night. It is expected that there is potential for increased catches and further reductions in fuel consumption through further optimization as experience in using the gear increases. A more detailed description of the actual cost changes will allow the adaption of the technology to other vessels.
Goal: to test the effectiveness of pelagic bottom trawls compared to conventional bottom trawls.
Sub-goals
• To compare the efficiency of pelagic bottom trawls and bottom trawls during direct fishing for saithe.
• To describe the operation of the tool and concretize practical issues.
• To conclude with further progress and plan for a long-term race with relevant partners.
• To prepare a new operating profile with the use of new tools (seasons, most efficient use, etc.).
