Moedjair

Moedjair or Mujair (1890–1957) is a Javanese inventor who in 1939 was the first to culture the fish species Tilapia zillii, at the mouth of the Serang River, in the northern reaches of Java Island.

[citation needed] Moedjair was born Iwan Dalauk in 1890 in Blitar, East Java; he died there in 1957.

He noticed a strange fish that fed its children when in danger and spit back when they reached safety.

Wishing to bring a specimen home, Moedjair questioned whether the fish would survive a non-saltwater environment.

These 4 fish, released in rivers and lakes, quickly grew in population.
