Abstract：The experiment was designed to investigate the effects of different water sources on the growth performance and physiological and biochemical indexes of Litopenaeus vannamei under freshwater pond culture conditions.Two ponds from a cooperative in Hami City were selected as experimental ponds.Pond 1-1#was supplied with reservoir water,while pond 2-1#was supplied with groundwater from a well.During the experimental period,water quality was tested twice daily.After the shrimp larvae completed the acclimatization and hardening process,they were stocked into the open ponds for culture.A small pond was set up along the edge of each experimental pond,and 1 000 Litopenaeus vannamei with similar body length and weight were stocked in each small pond.The growth performance indicators,such as body length and weight,were measured every 15 days,with a measurement cycle of 90 days.The results showed that during the entire culture period,the water temperature in both ponds first increased and then decreased,while the dissolved oxygen,pH,and hardness remained relatively stable.The ammonia nitrogen and nitrite levels in pond 2-1#were relatively stable.In pond 1-1#,the ammonia nitrogen and nitrite levels in the water increased in the later stages of culture as the culture time extended.The changes in body length,weight,specific growth rate of body length,growth rate,specific growth rate of body weight,and weight gain rate of the shrimp in both ponds were generally consistent across different measurement stages.The final body length,final weight,growth rate,weight gain rate,and specific growth rate of body length of the shrimp in pond 2-1#were higher than those in pond 1-1#,but the differences were not significant(P>0.05).The specific growth rate of body weight of the shrimp in pond 2-1#was significantly higher than that in pond 1-1#(P<0.05).There were no significant differences in the serum albumin,catalase,lysozyme,alanine aminotransferase,high-density lipoprotein cholesterol,superoxide dismutase,peroxidase,catalase,lysozyme,acid phosphatase,and alkaline phosphatase levels of the shrimp between the two ponds(P>0.05).The study indicates that both groundwater and reservoir water can be used for Litopenaeus vannamei culture in Hami City,Xinjiang.However,the use of groundwater for shrimp culture is more effective than that of reservoir water.
