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...
متن کاملDistribution of intestinal enzyme activities along the intestinal tract of cultured Nile tilapia, Oreochromis niloticus L
Regional distribution of intestinal enzymes in Nile tilapia was investigated using enzyme histochemistry. Samples from adult fish were obtained from the five major intestinal segments. Activities of maltase, leucine aminopeptidase, dipeptidyl aminopeptidase IV, lipase, non-specific esterases, and alkaline phosphatase were examined in each segment. All enzymes were present at specific sites alon...
متن کاملThe 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...
متن کاملMetacercarial Infection of Wild Nile Tilapia (Oreochromis niloticus) from Brazil
Fingerlings of Oreochromis niloticus collected in an artificial urban lake from Belo Horizonte, Minas Gerais, Brazil, were evaluated for natural infection with trematodes. Morphological taxonomic identification of four fluke species was performed in O. niloticus examined, and the total prevalence of metacercariae was 60.7% (37/61). Centrocestus formosanus, a heterophyid found in the gills, was ...
متن کاملVisual 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...
