The effect of black glutinous rice bran (Oryza sativa L.) in diets of Nile tilapia (Oreochromis niloticus)

The effect of black glutinous rice bran (Oryza sativa L.) in diets of Nile tilapia (Oreochromis niloticus)

The effect of black glutinous rice bran inclusion used in diets of Nile tilapia was  studied in fish with an initial weight of 8.76±0.17g per fish and fed with experimental diets supplemented with black glutinous rice bran at 0 (control), 50, 100, 150 and 200 g kg-1 for 60 days. The results of phytochemical analyses of black rice bran showed that the total anthocyanin, phenolic, tannin and phyt...

Visual communication stimulates reproduction in Nile tilapia, Oreochromis niloticus (L.).

Reproductive fish behavior is affected by male-female interactions that stimulate physiological responses such as hormonal release and gonad development. During male-female interactions, visual and chemical communication can modulate fish reproduction. The aim of the present study was to test the effect of visual and chemical male-female interaction on the gonad development and reproductive beh...

Effect of salinity on food consumption and growth of juvenile Nile tilapia (Oreochromis niloticus L.)

The effect of salinity (0, lO and 20%o, water temperature 28 ± l oC) on food consumption and growth of juvenile Nile tilapia, Oreochromis niloticus L. (9.94 ± 0.15 g) were investigated by feeding group of 20 fish at 2% body weight day·• Individual food consumption was measured using X-radiography. There were no significant differences in growth or white muscle protein concenrrarions among group...

Behaviours Associated with Acoustic Communication in Nile Tilapia (Oreochromis niloticus)

BACKGROUND Sound production is widespread among fishes and accompanies many social interactions. The literature reports twenty-nine cichlid species known to produce sounds during aggressive and courtship displays, but the precise range in behavioural contexts is unclear. This study aims to describe the various Oreochromis niloticus behaviours that are associated with sound production in order t...
