<![CDATA[The purpose of this study is to see how adding the amino acid lysine to commercial feed affects the amount of EPA and DHA in catfish (Pangasius sp.) flesh. This study is an experimental study with a totally randomized design that includes four treatments and five replications. P0 (100% commercial feed + 1.2 percent amino acid lysine), P2 (100% commercial feed + 2.2 percent amino acid lysine), and P3 (100% commercial feed + 3.2 percent amino acid lysine) were the treatments. The parameters observed were EPA and DHA in catfish meat. Data analysis used ANOVA and continued with the DUNCAN test (p 0.05). The results showed that the addition of the amino acid lysine to commercial feed for 30 days of maintenance was able to increase the EPA and DHA content in catfish meat. The highest EPA content was obtained by treatment P1 (1.2% amino acid lysine), which was 0.597%, while the highest DHA content was obtained by treatment P2 (2.2% amino acid lysine), which was 0.747%. Our findings demonstrate that adding the amino acid lysine to the diet can result in nutrient-rich catfish flesh. However, studies on the influence of lysine amino acid on the growth rate, survival rate, and cholesterol ratio in catfish flesh are predicted to enhance the productivity of this very nutritious fish.]]>
