| Summary: | Utilization of fish based-waste as feed is a very efficient alternative in reducing pollution and environmental damage, and meeting the nutritional needs of fish growth. This study aims to test the quality of fish feed made from waste flour
Euthynnus affinis based on physical, chemical and biological tests for gourami. This research was conducted in 2024. The study used a completely randomized design (CRD) with 4 replications and 5 treatments. The addition of fish waste flour includes: P1 (0%) control, P2 (35%), P3 (40%), P4 (45%) and P5 (50%). The results showed that the ANOVA test on the physical test, the addition of waste flour in artificial feed for gourami significantly different (P <0.05) on the breaking speed and sinking speed with the highest value in treatment P5 (50%) which is 14.51 minutes and 0.05 seconds. However, there was no significant effect (P>0.05) on the dispersion of solids, level of hardness, level of homogenesis and feed attractiveness. The results of chemical tests (proximate) showed that feed without the addition of waste flour and feed with the addition of waste flour provided protein content values of 20.89% and 30-32%. In biological studies, the addition of waste flour to feed had no significant impact (P>0.05) on gourami survival, but it had an important effect (P<0.05) on weight. The highest growth value was found in the P4 treatment (45%) which amounted to 2.46 g with survival ranging from 90% ± 0.00. Therefore, from each treatment it can be concluded that the addition of raw materials of waste flour in feed provides a good nutritional value for the growth of gourami. |
