exposure in our aquaculture (Fernandes et al., 2009). Fernandes et al. (2009) validated this evidence by their research, which showed toxic levels of PCBs in five different types of farmed fish. Due to this knowledge, there has been a change in diets and fish food used in aquaculture (Betancor et al., 2015).
Dietary fish oil (FO), which is known to contain pollutants, is being replaced with vegetable oils (VO), which does not contain the natural fatty acids needed for proper digestion (Betancor et al., 2015). Overall, this has been shown to have negative effects on aquatic life, specifically farmed fish. With our fast growing population, FO is not a realistic source of food for salmon in particular, because it is expensive and limited in resources. Betancor et al. (2015), sought to conduct a study that tested the effects of high-EPA oil (ECO) on the digestion of salmon along with performance and lipid contents. This high-EPA oil is obtained from the transgenic Camelina sativa plant (Betancor et al., 2015). Salmon that were fed ECO had sustainable lives and fat samples proved to be healthy and safe (Betancor et al., 2015). Overall, their findings suggest ECO as a healthy alternative to FO in fish food (Betancor et al., 2015). Further research needs to be conducted in order to provide more substantial evidence of the positive effects of ECO (Betancor et al., 2015). This study gives hope to the future as to how fish farms will be able to sustain vast quantities of fish safely…
