Life habits

At different growth and development stages, the habitat habits of Macrobrachium rosenbergii are different or even opposite. During the larval development stage of Macrobrachium rosenbergii, it must live in brackish water with a certain salinity. It lives a planktonic life with its abdomen always facing the sky, its back facing the ground, its tail tilted upward, and its head tilted downward. If placed in pure fresh water during this period, it will die soon.
