The effects of fish meal substitution with Black Soldier Fly Larvae (BSFL) and earthworm on growth performance and water quality of Betta fish (Betta Splendens)

This study aims to identify The Effect of Different Fish Feed On the water quality Of Ornamental Fish (Betta Splendens). The feed cost can rise by more than 70% of production because the soybean and fish meal are costly. The replacement of Black Soldier Fly Larvae (BSFL) and earthworm in feed ingredients can cut off the feed cost. Both BSFL and earthworm contain the nutrient composition that meets the requirement of fish feed. This experiment was done to find an alternative for fish meals. The feed that contains more protein is better for the fish. Unfortunately, there are a lot of factors that can affect the development of the Betta Splendens, such as water quality. The water quality that will be observed is that pH level, water temperature, Dissolved oxygen level and ammonia level. Three types of feeding trial, fish meal (control), BSFL, and earthworm used to determine the better water quality for the fish.
