Abstract
Fish oil, rich in essential fatty acids, is a crucial component of fish feed due to its numerous health benefits for aquatic species. However, the rising demand for fish oil in aquaculture has led researchers to explore alternative sources of lipids. Canola oil, derived from rapeseed, has emerged as a prominent candidate due to its favorable fatty acid composition and cost-effectiveness. Alpha-linolenic acid (ALA) and linoleic acid (LA), two essential fatty acids (EFA) for fish health, are found in canola oil. The study presents examples of the successful incorporation of canola oil in fish diets. It demonstrates that it can replace up to 100% of fish oil for freshwater species and up to 60% for marine species without compromising growth rates. The research suggests that canola oil holds promise as a sustainable alternative source of lipids for fish feeds, contributing to the goal of achieving efficient and cost-effective fish farming practices.
