The Effect of Functional Male Broodstock Sex Ratio on Fertilization and Hatching Rate of Climbing Perch (Anabas testudineus Bloch)

One approach to optimizing the effectiveness of functional male broodstock is by using different sex ratios during the spawning of climbing perch. This study aimed to analyze the effect of sex ratio on the fertilization and hatching rate of climbing perch. The main research was conducted at the Freshwater Aquaculture Research Center, Mandiangin, South Kalimantan. A Completely Randomized Design with 4 treatments and 3 replicates was employed. The research parameters were fertilization and hatching rate of the eggs. The effect of sex ratio on fertilization and hatching rate showed that the highest fertility rate was 94.40% in Treatment C (1:3 ratio), and the best hatching rate was 99.44% in Treatment B (1:2 ratio).
