Abstract
Water salinity is one of the environmental factors that affect the hatching rate of the fish. The aims of this study were to find out the influence of salinity to embryogenesis and hatching rate of giant gourami at the different salinities. This study used four treatments and three replications. The treatments were A 0 ppt, B 1-2 ppt, C 3-4 ppt, and D 5-6 ppt. The salinity was made by adding salt water to the fresh water in aquarium. The number of eggs in each treatment was 32 grains respectively. The parameters observed were the embryogenesis, fertility, hatching rate, hatching time, and water quality. The results showed that salinity influenced the embryogenesis duration of eggs during blastula and gastrula stages, but did not influence to the hatching rate and hatching time of eggs.
