Abstract

Static bioassay tests for acute toxicity of four pesticides on the prawn Penaeus
monodon in brackishwater medium were conducted. The 96 h LC„ values of
pesticides such as DDT, BHC(HCH), heptachlor and endosulfan were found
to be 2.08, 4.10, 16.25 and 2.90 ppb respectively for prawns of size group 33-
46 mm. Admissible safe concentration for DDT, BHC, heptachlor and
endosulfan were 0.21, 0.41,1.63, 0.29 ppb respectively. LCj,, values were also
calculated for each time interval and toxicity of the pesticides was compared
using toxicity curves. Pesticides were not detected in creek and coastal waters.
