Abstract
Mortality to fish Channa punctatus caused by the latices of four species of terrestrial plants belonging to family Euphorbiaceae and Apocynaceae have been reported. It was found that extremely dilute aqueous solutions of the latex were effective in killing the fishes. The ranking of toxicity of four plants was Nerium indicum > Euphorbia royleana > Thevetia peruviana > Jatropha gossypifolia. It has been suggested that these plant products cannot be used directly in freshwater ecosystem unless their detailed toxicity has been studied on the beneficial freshwater animals.
Die akute Toxizität von Pestiziden pflanzlichen Ursprunges für den Süßwasserfisch Channa punctatus
Berichtet wird über die Mortalität von Channa punctatus, verursacht durch die Säfte aus vier terrestrischen Pflanzenarten der Familien Euphorbiaceae und Apocynaceae. Selbst extreme wässrige Verdünnungen der Pflanzensäfte erwiesen sich als effektiv toxisch für die Fischart. Die Reihenfolge der Toxizität ergibt sich zu Nerium indicum > Euphorbia royleana > Thevetia peruviana > Jatropha gossypifolia. Es wird vorgeschlagen, diese pflanzlichen Produkte nicht in Süßwassersystemen anzuwenden, bevor nicht ihre Toxizität gegen Süßwasserorganismen näher untersucht ist.
