Icthyotoxic assessment of water extract from fresh Euphorbia heterophylla (L) plant stem to Barbus occidentalis (Pisces: Cyprinidae) (Boulencer, 1920) fingerlings
Icthyotoxic assessment of water extract from fresh Euphorbia heterophylla (Limnaeus) plant stem on Barbus occidentalis (Boulenger, 1920) fingerlings was conducted using static bioassay tests over a period of 96 hours. The range finding test was userd to determine the lethal concentration of the botanical on B. occidentalis and was found to induce varying behavioural response in the fish. The 96h median lethal concentration (LC50) of 2.42g/l and safety level of 0.24g/l were determined for B.
