Paper Title:
Effects of Dimethylhydantoin and Carbohydrate on Growth and Immunity of Litopenaeus vannamei
  Abstract

Three experiments were conducted to study the effects of dimethylhydantoin (DBH) and carbohydrate on growth and immunity of Litopenaeus vannamei under low salinity conditions. Experiment 1 examined the effect of DBH on the survival of L. vannamei. The results showed that with increasing DBH concentration, the survival rate of L. vannamei exhibited decreased trends at salinities of 0.2, 5 and 20, while the safety concentration of DBH to L. vannamei increased with the rise of salinity. Experiment 2 and 3 examined the effects of salinity, DBH and carbohydrate on growth and immunity of L. vannamei, the results show that under low salinity culture conditions, the long-term living in the DBH environment of L. vannamei could lead to stresses, the shrimps needed to consume more immune factors, so the activities of phenoloxidase and superoxide dismutase in serum decreased, and the growth rates depressed, while the increase in the amount of carbohydrate in diets could not only promote the growth of shrimps, but also played a role in diet protein conservation.
