چکیده مقاله:

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 phytic acid contents were 52.42±0.23, 3.77±0.03, 0.32±0.13, 0.14±0.01 mg/100g, respectively. The properties of black glutinous rice bran acted as an antioxidant, and the inhibitory percentage of 1,1-diphenyl-2-picrylhydrazyl (DPPH) and thiobarbituric acid reactive substances (TBARs) was significantly different (p<0.05) on storage in different conditions of 4 and 25 ºC. Black glutinous rice bran stored at 4 °C showed significantly higher antioxidant activities analyzed by DPPH and TBARs tests (p<0.05). The percentage of digestibility coefficients and protein digestibility in test diets ranged from 75.21-81.95 and 87.37-91.87 (p>0.05), respectively. The highest average daily gain, specific growth rate and protein efficiency ratio were observed in fish fed with the diet containing  150 and 200 g kg-1 black rice bran (p<0.05). Feed conversion ratio was slightly better in fish fed the diet supplemented with 200 g kg-1 black glutinous rice bran. The serum biochemical values including total protein, albumin, total bilirubin, alkaline phosphatase (ALP), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activity were not significantly different in the various experimental groups (p>0.05). Therefore, supplementation of black glutinous rice bran in tilapia diets at a rate of 200 g kg-1 resulted in better growth and had no adverse effects on digestibility and serum biochemistry.

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...

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...
