The technology of striped catfish broodstock (Pangasius hypophthalmus) in high-quality maintenance

Striped catfish (P. hypophthalmus) is a high economic value and is a determining factor at the hatchery stage. Quality catfish brooders that can produce superior seeds can be obtained through good handling. The purpose of this study is to gain knowledge in the maintenance techniques of catfish broodstock. The working methods used in the study is a descriptive method with primary and secondary data collection. Striped catfish broodstock uses a recirculation system which includes preparation of pond maintenance, broodstock maintenance, feed management, water quality management, broodstock selection, and spawning. The results of the average water quality parameters for 25 days are turbidity 17.85 cm, temperature 29.51°C, DO 4.23 mg/L, ammonium 0.005 mg/L, and pH 7.54. The average weight measurements in the first and second sampling are 3.11 kg and 3.13 kg, while the average length measurements in the first and second sampling are 55 cm and 56.05 cm. The growth rate in the maintenance of catfish broodstock for 21 days is 9.52 grams/day, and the specific growth rate is 0.028%. Catfish spawning uses a ratio of ten males and three females.
