Variation in penaeid shrimp growth rates along an estuarine salinity gradient: Implications for managing river diversions

► We compared growth rates of juvenile penaeids along an estuarine salinity gradient. ► In 2 experiments, brown shrimp and white shrimp were held for 7 days in field mesocosms. ► Growth rates for both species were reduced in low salinity areas. ► Result was likely due to higher metabolic cost and less food in low salinity habitat.
