The main factor influencing catfish farming activities is the use of feed. Catfish feed in the form of fish pellets has a relatively expensive price, thereby reducing profits in catfish farming, so alternative feeds are needed. An alternative feed that has the potential to be used in catfish farming is BSF (Black Soldier Fly) maggot. This BSF maggot has a high nutritional content, namely 42-45% protein, 31-35?t, 20% ash residue. The purpose of this study was to determine the impact of using a mixture of BSF maggot and pellets on the growth of catfish. The feed given to catfish is fish pellet, a mixture of fish pellet with BSF maggot, and BSF maggot. This study used a completely randomized design method (CRD) with 4 different treatments of BSF maggot percentage, each treatment had 5 replications with. The variations used were 0% BSF maggot and 100% fish pellet, 25% BSF maggot and 75% fish pellet, 75% BSF maggot and 25% fish pellet, and 100% BSF maggot. Feeds are given 3% of total body weight of the fishes. The results showed that feed variations with 0% BSF maggot and 100% fish pellet is the best feed for increasing length and weight with 2,467 cm and 12,67 gr growth but has a low survival rate with only 20% thus making the EFU value 16,72% which is relatively low. On the other hand feed variation with 25% BSF maggot and 75% fish pellets is the second best for increasing length and weight with 2,3 cm and 10,8 gr growth and has a really high survival rate with 90% thus making the EFU highest value 64,15%. |
