The project complies with the HAVBRUK programme call in that it aims: to develop new lipid sources rich in EPA and/or DHA for use in salmon feed that are sustainable, safe and cost-effective.
There may be several options for n-3 LC-PUFA production. However, vegetable platforms are practical in that they are highly organised with a well-established infrastructure for the cultivation, harvest, processing, distribution, marketing and utilisation. The production of n-3 LC-PUFA in the transgenic oilseed crop, Camelina sativa has recently been demonstrated by one of the partners. This was obtained by transformation with algal genes encoding the n-3 LC-PUFA biosynthetic pathway. The resulting oils have over 20 % of total fatty acids as n-3 LC-PUFA. These oils represent a real solution to the supply of EPA and DHA for the aquaculture industry that will maintain the nutritional quality and healthy status of farmed salmon. These transgenic oilseeds can be scaled up to commercial volumes in a relatively short time. Furthermore, as simply a modified vegetable oil, the cost of transgenic Camelina oil should not be prohibitive and are undoubtedly far cheaper than the alternatives. Production of the transgenic oilseed crops can expand as required to satisfy demand from all sectors including both aquaculture and direct human consumption in a responsible and sustainable fashion.
The current project will first evaluate the suitability of a current Camelina oil with 18% 18:2n-6 in salmon. Then, based on this information a new transgenic Camelina will be engineered with a lower target level of 18:2n-6 and tested again. Fish from both trials will be extensively examined with regard to growth, feed efficiency, metabolic impacts, health and welfare parameters using molecular, clinical and biochemical tools.
