Best Rearing Technique for Nilem Fish Larvae (Osteochilus hasselti)

Aquaculture

The increase in the cultivation of nilem fish (Osteochilus hasselti) causes the risk of an increase in the need for larvae. However, there are problems faced, namely larval mortality which is still high. High larval mortality usually occurs in the developmental phase, which is a critical phase when the yolk sac begins to run out and also a transition period when the larvae begin to utilize external food. The adaptation period of fish larvae from endogenous to exogenous food sources needs to be well understood by fish farmers, so that their hatchery business can run smoothly. Nilem fish is one of the fish that eats moss, algae, periphyton, aquatic plants, and plankton. This study aims to determine the technique of rearing nilem fish larvae. This study used 10 days old nilem fish larvae. The implementation method used is the participatory method and the data collection method uses primary data and secondary data. The results obtained were nilem fish larvae had an absolute
