The enlargement of shrimp culture has been rapid in recent years.The present study was conducted during the year 2018 to estimate shrimp performance such as survival and growth rate of P. vannamei both in ponds cultured with hatchery reared and nursery reared post larvae in different seasonal crops.The ponds selected for this study are located at Yazali, in Guntur District of Andhra Pradesh.The maximum growth was recorded in grams as 38.17±0.47 and 36.26±0.51,34.58±0.43 and 31.46±0.32for both summer and winter crops at 120 days culture in nursery and hatchery reared ponds respectively.With regard to survival rate the maximum survival of 83.27 and 81.52 was recorded for both summer and winter crops respectively.The present data revealed that, the highest augmentation in survival and growth rate are recorded in the culture ponds of nursery reared post larvae than hatchery reared post larvae.
