STUDIES OF ACUIE INTOXICATION BY SOME HARMFUL SUBSTANCES ON PENAEUS ORIENTALIS K
Abstract:
The effects of toxicity in 23 kinds harmful Substances on eggs, post-larvae and juvenile prawn (Penaeus orientalis) in normal temperature and static water conditions were studied. The order of toxicity level was Hg++, Cu++, Zn++, phenol and Pb++. The order of toxicity-tolerance capacity was juvenile, post-larvae and eggs of prawn. The toxicity ofpesticides to prawn was 2-3 magnitudes stronger than that to fish. The TLm value of juvenile prawn to organic Phosphorus pesticides was 1 magnitude smaller than that of Hg++. The order of toxicity of four pesticides to prawn was Malathion, Systox(Demeton), Diptenex (Trichlorfon), Chlordimeform. The toxicity in light oil was stronger than that of heavyoil to juvenile prawn. Five kinds of phenol compound differ in toxicity according to groupscontained in the compounds and their base arrangement.
