Fish Cultivation Techniques for Common Carp (Cyprinus carpio Linn.) Strain “Mantap” at Center for Freshwater Fish Cultivation (BBPBAT) Sukabumi, West Java, Indonesia

The cultivation of Carp (Cyprinus carpio, Linn) in hatcheries can be approached through various methods, including traditional, semi-intensive, and intensive techniques. Presently, many hatchery operations still adhere to traditional practices. This activity aimed to actively engage with, study, apply and report advanced techniques in the breeding of Common Carp (Cyprinus carpio, Linn). This practical training was conducted between May 22, 2023, and July 14, 2023, at the Sukabumi Freshwater Aquaculture Center (BBPBAT). Data collection during the activity encompassed both primary and secondary sources. Natural spawning of Common Carp was executed with a male-to-female sex ratio of 2:1, utilizing 60 male broodstock with an average weight of 500 grams and 30 female broodstock weighing around 2,000 grams each. The results of this spawning procedure yielded a fertilization rate of 82.77% and a hatching rate of 68%. Subsequently, 600,000 larvae were obtained from the spawning process. These larvae were then transferred to a nursery pond with a stocking density of 300 individuals per square meter (300 individuals/m2). Over a span of 24 days in the nursery pond, a survival rate of 51.5% was achieved. This activity served as a hands-on exploration of advanced Common Carp breeding techniques at the BBPBAT facility, providing valuable insights into modern hatchery management.
