Abstract
One of the obstacles that exist in this carp hatchery business is the lack of knowledge about the quality of feed that is not in accordance with the nutrients needed by fish. Feed quality that does not match the needs of the fish will lead to a low life-pass rate and fish growth rate. To overcome this, feed mixtures are made using fermented banana stems as a source of probiotics. The use of probiotics becomes an internal solution to produce optimal feed growth and efficiency, reduce production costs, and ultimately reduce environmental burdens due to waste accumulation in waters. The purpose of this study was to determine the right dose and effectiveness of adding probiotics from fermented banana stems mixed directly in carp seed feed on the growth and survival of carp fry. This study was designed using a complete randomised design (CRD). It consisted of 4 treatments and 3 replication for a total of 12 experimental units. The treatments used in this study were treatment A (control), treatment B (1.5 ml/100 g feed), treatment C (3.0 ml/100 g feed), and treatment D (4.5 ml/100 g feed). Based on the results of the study, the highest growth in absolute length and absolute weight and the highest survival occurred in treatment C (3.0 ml/100 g of feed).
