Acute Toxicity of the Pesticides, Dichlorvos and Lindane against the African air-breathing catfish, Heterobranchus longifilis, Valenciennes, 1840 (Siluriformes: Clariidae)

Since H. longifilis is sensitive to the test pesticides, it can therefore be considered as a good test species for the determination of acute toxicity and poisoning resulting from the pesticides and possibly for other compounds with similar intrinsic characteristics.
