Extensive Net Cage Culture of Nile Tilapia (Oreochromis niloticus) Fingerlings in Nutrient-enriched Pond
To investigate the potential of extensive net cage culture for Nile tilapia (Oreochromis niloticus) fingerlings, an experiment was conducted in net cages suspended in a fertilized pond. Mixed-sex population of Nile tilapia with an average initial body weight of 0.065 g was used to stock in experimental cages. Four treatments; non added-substrate without supplemental feeding (NSNF), non added-su...
متن کاملHeterogeneous growth fingerlings of the Nile tilapia Oreochromis niloticus: effects of density and initial size variability.
In this study, the effect of initial heterogeneity of weight and density on heterogeneous growth (HetG) evaluated by the coefficient of the variation of weight in the young Nile tilapia Oreochromis niloticus of the territorial species was tested. Fish were maintained in a glass aquarium (8 and 2 L of water) with two levels of initial heterogeneity of weight: low and high, under two density cond...
متن کاملEffect of Dietary α-Cellulose Levels on the Growth Parameters of Nile Tilapia Oreochromis niloticus Fingerlings
Three purified diets were formulated using fish meal, soya bean, wheat flour, palm oil, minerals and maltose. The carbohydrate in the diets was increased from 5 to 15% by changing the cellulose content to study the effect of dietary carbohydrate level on the growth parameters of Nile tilapia Oreochromis niloticus. The protein and the lipid contents were kept constant in all the diets. The resul...
متن کاملBehaviours 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 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...
