Abstract

Abstract. Feeding rate is based on the estimated percent of feed per shrimp weight. The purpose of this study was to determine the effect of the used feeding rate on the water quality profile and on the biological growth of white shrimp (Litopenaeus vannamei). This research was conducted using an ex-post facto causal design concept in an intensive shrimp pond with a size of 2,000 m 2 . The indicators observed in this study were the water quality parameters and the biological indicators of shrimp, as well as the percentage of feed rate used in ponds during the cultivation cycle. The results showed that the water quality parameter values remained stable, with a pH value of 8.2 (±0.15), a salinity of 17‰ (±6.50), a dissolved oxygen of 5.87 mg L -1 (±0.51), a green water color, a temperature of 28.59°C (±1.19), an organic matter concentration of 93.48 mg L -1 (±17.02), a brightness of 36 cm (±24.75). The organic matter content in ponds has a positive correlation with the brightness value, which is described by the equation Y=144.20+1.16x. The shrimp growth rate is positively correlated with the shrimp weight, which is described by the equation Y=5.98+79.58x. The feed rate in ponds has a correlation value of 0.725 with the shrimp weight and of 0.587 with the brightness. The feed rate also has a relationship with the shrimp biomass, which is described by the equation model Y=43.26+0.01x. Based on the results of this study, it can be concluded that the use of feeding rate during the cultivation cycle has a significant effect on the shrimp weight and on the value of pond water brightness.
