| Abstract: |
| In our experiment the platinum pole wes adoptid to electrolize seawater to produce chlorine. When the concentration of the residucl chlorine in seawatcr was 0.5ppm., the qualified sterilized scawater would be obtained, and then could be used after 24 hours as the culture seawater for the prawn larvae. The prawn larvae taken at the different stages of development were cultured in the sterilized seawaler and in natural seawater as the control. The experimetal results showed that the survival rate of the prawn larvae was increased (see the following table)......It was also found that the rurvival rate of the prawn larvae could be raised when fodwith living food organioms, which were washed 2 or 3 times with the sterilized seawater. |
