Abstract
The striped snakehead (Channa striata Bloch, 1793) is a freshwater fish commonly found in freshwater bodies such as rivers, swamps and lakes. Long known as a desirable food fish, the striped snakehead has a high albumin protein content which can help to accelerate wound healing, facilitate the movement of body fluids and maintain osmotic pressure in the body. Several limiting factors are thought to affect the growth and survival of fish, one of which is salinity, which can directly affect the metabolism of fish such as striped snakeheads. The purpose of this study was to determine the effect of different salinity treatments on the growth and albumin content of juvenile striped snakeheads. The research was conducted during November-December 2021 at the Water Quality and Aquatic Biology Laboratory, Faculty of Animal Husbandry and Fisheries, Tadulako University, Indonesia. The study applied 5 treatments (2 ppt, 4 ppt, 6 ppt, 8 ppt and 10 ppt) with 8 replicates. The Honestly Significant Difference (HSD) test showed that the net increase in length and weight were significantly different (P less than 0.05) between treatments. The 8 ppt salinity treatment gave the highest growth (mean 1.04 cm, SD 0.19 cm), survival rate (100%) and albumin content (4.950 mg/100 mL).
