A peoples are doing belida fish cultivation to measure the length and weight of the fish.
Belida fish (Chitala fish) is a type of freshwater fish which is an endemic fauna native to Indonesia.
This fish lives in large rivers, watersheds and lake areas around the islands of Java, Kalimantan and Sumatra.
Included in the Notoperidae family, this fish turns out to be a primitive or ancient fish group.

Belida fish, now increasingly difficult to find. In fact, some of their natural habitats in Indonesia are not easy to find. For example, in the Musi River, Palembang, South Sumatra, and in the Batanghari River, Jambi, this fish is considered very rare. This situation is certainly quite alarming. It is not impossible that if this continues, the belida fish will be completely extinct. so it is necessary for the cultivation of these fish.
