pond. Rutledge and Guest have been reported that because the better
water quality is essential for good shrimp production, several parameters
were monitored daily and many were present within optimal ranges
for the shrimp production [11,12]. Maguire and Allen stated that the
temperatures play an important role in Shrimp culture [13]. Optimal
temperature has been reported between 27–33oC. But in the case of
the present study observed the water temperature (29.6ᵒC) does not
show much variation among the three ponds and also optimum for L.
vannamei culture. In case of DO the optimal is between 3-5 ppm and
lower levels may result in mortality [14,15]. Lee and Wickens, Garcia
and Bruna, the other hand to study was demonstrated that the DO level
was varied between 2.2 and 4.6 ml/l, almost optimum for L. vannamei
culture. It is a euryhaline animal can tolerate the wide range of salinity
from 2 to 45 ppt. the result showed the optimum salinity range in the
present study.
