Abstract

Intensive vannamei shrimp (Litopenaeus vannamei) farming using a fermentation-based system offers an innovative solution to environmental management and production efficiency. This study was conducted over one cultivation cycle (80 days) in six ponds operated by CV Tambak 58, North Bali, integrating periodic probiotic fermentation. Key parameters evaluated included growth (ABW, ADG), feed efficiency (FCR), survival rate (SR), water quality, and microbiological stability. Results showed high productivity (up to 2.53 kg/m²), low FCR (1.13–1.40), and SR >85%, accompanied by stable planktonic and microbial communities. These findings indicate that fermentation-based systems reduce environmental stress and disease risks while enhancing the sustainability of intensive shrimp aquaculture

Abstract

High feed costs remain a major constraint in the cultivation of Asian seabass (Lates calcarifer) in floating net cages (FNC), necessitating a more efficient feeding strategy without compromising fish growth performance. This study aims to analyze the effect of a combination of commercial feed and lemuru fish (Sardinella longiceps) on the feed efficiency and growth of Asian seabass, as well as to determine the most optimal feed combination. The research employed an experimental method utilizing a Randomized Block Design (RBD) consisting of three treatments and three replications: Treatment A (100% commercial feed), Treatment B (75% commercial feed + 25% lemuru fish), and Treatment C (50% commercial feed + 50% lemuru fish). The observed parameters included absolute length growth, absolute weight growth, specific growth rate (SGR), feed conversion ratio (FCR), survival rate (SR), and water quality. Data were analyzed using Analysis of Variance (ANOVA) at a 95% confidence level, followed by the Least Significant Difference (LSD) test. The results indicated that the feed combinations significantly affected growth and feed efficiency (p < 0.05). Treatment B yielded the best performance with an absolute length growth of 5.07 cm, an absolute weight growth of 50.5 g, an SGR of 2.225% per day, and the lowest FCR of 1.877 g/g. The fish survival rate ranged from 90% to 93%, while water quality parameters remained within the optimal range throughout the study. Therefore, the combination of 75% commercial feed and 25% lemuru fish is the most effective formulation for improving the feed efficiency and growth of Asian seabass in the floating net cage system.
