Abstract

Abstract. Pacific white shrimp (Litopenaeus vannamei) has been successfully cultivated in low salinity and in freshwater. Some constraints that arise in the cultivation process include the deficiency of macrominerals, such as sodium, magnesium, calcium, and potassium. The presence of these macrominerals and their proportion affect their absorption by shrimp. Therefore, this study aims to determine the effect of different ratios of sodium (Na+) and potassium (K+) on the growth and survival rate of Pacific white shrimp reared in freshwater media. A completely randomized design (CRD) was used, with 3 treatments and 4 repetitions. The treatments were represented by different ratios of Na and K, namely: A - 17:1; B - 27:1; C - 37:1. The duration of the experiment was 35 days. The results showed that the ratio of sodium and potassium in freshwater media significantly affected (р<0.05) the growth and survival rate of Pacific white shrimp. B treatment gave the best growth and survival rates, namely 69.50±5.26% and 1.69 ±0.03 g, respectively, with a specific growth rate of 11.90±0.04%. Observations of water quality showed that it is in line with the standards for shrimp farming. Furthermore, Vibrio was not found in any treatment group at the end of the experiment. Key Words: K+, macromineral, Na+, Vibrio
