Abstract

The acute toxicity tests for sodium cyanide and formalin to freshwater edible fish
Lepidocephalichthys guntea were conducted by static renewal bioassay methods.
The 24, 48, 72 and 96 hour LC^,, values for sodium cyanide were 0.42, 0.39, 0.36
and 0.33 mg/1 respectively and for formalin were 111.0, 109.0, 107.0 and' 104.0
mg/1 respectively. The normal swimming behaviour and respiration of the fish
was greatly affected by both the toxicants. The oxygen consumption rate decreased
significantly to the said fish as the period of exposure varied and concentration
of toxicants increased.
