Effect of low salinities on the survival and growth of Penaeus monodon (Fabricius)

Effect of low salinity on the growth and survival of P. Monodon was studied under controlled conditions. Results indicated that even though low salinities had a highly significant influence on the growth rate of juveniles (P< 0.001), salinities ranging from 9 to 20 ppt did not influence growth rate. Large fluctuations in salinities ranging from 4 to 20 ppt were not a major factor influencing the survival (P>0.05). The probit regression line for the relation between the logarithmic salinity level (x) and mortality (y) was found to be y = 5.9820 + 13322x
