Mujair fish is a kind of freshwater fish commonly consumed. The natural spread of this fish is Africa and in Indonesia was first discovered by Mr. Mujair at the mouth of the Serang River on the southern coast of Blitar, East Java in 1939.
But now tilapia fish already in the swamp and multiplied (lam lungs).
Because at the time of tsunami aceh in 2004 ago this fish was carried by the tsunami to spread to some areas.
After the tsunami hit Aceh on 26 December 2004, the distribution of the tilapia fish population became wider because it was carried away by the tsunami so that the place where there had never been tilapia fish became a new place for them.
But in 2022 the tilapia fish population in the river seems to be lost to the earth which is increasingly difficult to find them today.
