Abstract– The purpose of this study was to determine the lethal concentration (LC50) value of an extract of Luffa cylindrica fruit applied to Oreochromis mossambicus tilapia in the laboratory. After adding the extracts in proportion to the water in the aquarium, five distinct concentrations of the extract were produced: 8 g/l, 10 g/l, 12 g /l, 14 g /l, and 16 g /l. The lethal concentration (LC50) of Luffa cylindrica on Oreochromis mossambicus was determined to be 10.54 g/l for exposure periods of 96 hours. The dose response of mortality as well as alterations in behavioural patterns were investigated in relation to the Luffa cylindrica fruit extract.

Key words: Oreochromis mossambicus, Luffa cylindrical, toxicity
