Increasing Growth Performance and Omega-3 of Pangasius Catfish with Fish Oil Administration

Abstract

This research aims to examine the effect of adding fish oil on the growth performance and content of Omega-3 fatty acids in Pangasius catfish (Pangasius sp). The research carried out in October and November 2021 at the Faculty of Fisheries, Padjadjaran University. Pangasius catfish with an average weight of 12.41 gram were reared in a fiber tank with stocked with 15 giving a stocking density of 10 fish-1 m2. The fish were reared for 28 days. This study used a completely randomized design with five treatments with fish oil supplemented to the feed at 0%, 3%, 4%, 5%, and 6% with each treatment consisting of three replications. The fish were fed twice a day at 08:00 am and 16:00 pm West Indonesian time, at a feeding level of 3% of the fish biomass per day. The feed used was pellet for catfish from Hi Provite PF 781 brand. Parameter tested included SGR, feed efficiency, omega-3 content and water quality. The result showed optimum application of fish oil increasing growth performance, the highest SGR was 2.07% day-1, the best efficiency feed 85.85%, EPA content was 30.7 mg-1 100 gram and DHA was 10.6 mg-1 100 gram.
