gariepinus exposed to sub-lethal concentrations of Derris elliptica under laboratory conditions.
The root of Derris elliptica was used for this study.
gariepinus at different concentrations of Derris elliptica root powder are presented in Fig.
The non significant changes in the water parameters of various experimental media reported in this study showed that the sub-lethal concentrations of Derris elliptica did not adversely lead to reduction in water quality where slight changes were observed; the values were within normal range of fish tolerance.
Derris elliptica roots were collected in the state of Johor; Kota Johor Lama, Malaysia.
For that reason, an internal standard method was carried out to determine the concentration of rotenone in the liquid crude extract of Derris elliptica and to compare the bio-active constituent profile with the commercially available rotenoids cube resin manufactured by SAPHYR (France).
