Macrobrachium larvae were reared in gradually increasing salinities and in constant salinities of 14, 16, 18, and 20 ppt. Best survival (36%) was achieved not only in an increasing salinity but also in a constant salinity of 16 ppt. In a controlled spawning experiment, temperature was lowered from 27.5 C to 24.0 C for 2 weeks. It was then returned to 27.5 C, and an average of 52.9% of the females tested spawned within 1 week.
