Project Description: |
Fish require omega-3 fatty acids. Wild fish obtain omega-3 fatty acid through consumption of algae and plankton. Farmed fish are fed feeds containing fish oil. This increases demand on native fisheries and can introduce marine pollutants (mercury and PCB) into farmed and hatchery fish. Thus, the aquaculture industry desires a plant-based source of omega-3 fatty acid.
Camelina meal was evaluated in fish feed in 2005 (Fig. 8). Essentially, the fish absolutely refused to eat feeds containing camelina meal. We suspect that this rejection was due to high concentrations of lignans or glucosinolates in the feed.
Subsequently, camelina oil was evaluated as a component of fish feed (Fig. 9). Fish fed the camelina meal did not perform quite as well as fish fed feed containing fish oil. However, the fish did consume the feed containing camelina oil. Future research will focus on optimizing the camelina oil feeds for maximum fish production. |
