Experimentation with fish

Oreochromis mossambicus or "Java tilapia" first cultivated at freshwater in Java island by Moedjair.

In 1939, Mudjair went looking for fish at the river estuary along coast. 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. Experimenting with freshwater habitats, he demonstrated 4 fish can live in saltwater after 11 experiments. These 4 fish, released in rivers and lakes, quickly grew in population. To honor his work, the fish was named mujair in Indonesian, and mujair is now a popular freshwater fish in Indonesia.^[1]
