The profile of Carassius auratus growth and hepatosomatic index in different salinity

Abstract

Carassius fish culture is usually carried out in freshwater with 0 ppt salinity, but the maintenance of 0 ppt salinity is less comprehensive in distributing fish culture itself. Therefore maintenance of fish with raised salinity is one of the solutions for cultivators so that fish farming can optimally be distributed. This study aims to determine the growth and hepatosomatic index (HSI) of Carassius auratus that are maintained at different salinity for 30 days. This experimental study used a Completely Randomized Design (CRD) with four treatments, namely P0 (0 ppt), P1 (4 ppt), P2 (8 ppt), and P3 (12 ppt) with five replications. The parameters of this study were fish growth, hepatosomatic index (HSI), and survival rate (SR). The results showed that the salinity of 12 ppt gave a low growth value and the highest HSI value. The survival rate that is generated at all events is 100%.
