Spawning Technique of Tilapia (Oreochromis niloticus) at the Fish Fry Center in Cibiru, West Java

Abstract

The demand for fish consumption continues to rise due to its high protein content, leading to an inadequate supply of fish stocks. To address this issue, the utilization of public water bodies for fish cultivation is seen as a potential solution. Cultivating fish in public waters can significantly boost fish production and maximize water utilization. One crucial stage in freshwater fish farming is freshwater fish hatchery development, aimed at meeting market demand for fish. Tilapia, a type of freshwater fish, holds great potential for cultivation due to its low production costs, high economic value, and adaptability to various aquatic conditions. The Cibiru Fish Fry Center in Bandung City plays a crucial role in tilapia fry production, with tilapia spawning being a significant endeavor. Tilapia is a freshwater fish species known for its elongated body shape, flattened sides, and blackish color. It exhibits a remarkable tolerance to different salinity levels and feeds on both animals and plants. Tilapia spawning at the Cibiru Fish Fry Center involves careful preparation of spawning ponds and the use of kakaban and water nets as substrates for egg attachment. Approximately 30,000 larvae are produced per spawning, with a hatching rate of 80%. Larvae management takes place in the same ponds as the spawning ponds and fertilizer application is used to promote the growth of natural food sources for the larvae. Feeding management is crucial for tilapia cultivation, with proper nutrition and feed quality influencing gonadal maturity and overall fish growth. The success of tilapia fry production at the center relies on various factors, including careful spawning preparation, optimal larval management, and effective feeding management.
