The acute-lethal outside the forest areas in south-western
Nigeria (Adesina, 2008; Adesina and
Omitoyin, 2011).The tree is under-utilized
in aquaculture, but is known to contain
some piscicidal compounds that could be
lethargic to freshwater fishes. The use of
biodegradable piscicides of plant origin as
pond management tool in sustainable
aquaculture can be used to minimize
environmental hazards caused on aquatic
ecosystems by the non-biodegradable
piscicides. Oreochromis niloticus is a
member of the family cichlidae.
Oreochromis niloticus, is a highly cultivable
species and amenable to laboratory
work(Fafioye, 2012).
This study assessed the acute-lethal toxicity
(LC50) effect of Moringa oleifera fresh rootbark
extract on fresh water fish,
Oreochromis niloticus juveniles for 96-h.
