Heterogeneous 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 کاملExtensive 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 کاملReplacement of fish meal by plant protein sources in Nile tilapia (Oreochromis niloticus) diet: growth performance and utilization
The nutritional suitability and cost effectiveness of rice polish and mustard oil cake as protein sources in the diet of Nile tilapia (Oreochromis niloticus) were studied. This study introduced rice polish as a plant protein source for Nile tilapia and three diets were formulated using rice polish (0, 10 and 20%) and mustard oil cake (10.0, 17.6 and 22.0%) for a feeding trail of eight weeks to ...
متن کاملDifferential response of Tilapia guineensis fingerlings to inorganic fertilizer under various salinity regimes.
The influence of salinity on the response of the estuarine teleost, Tilapia guineensis fingerlings to acute toxic effects of inorganic nitrogen-phosphorus-potassium (NPK) (15: 15: 15) fertilizer was investigated using semi-static bioassay. The toxicity of NPK fertilizer was found to increase significantly with increase in the salinity level from 0.05 %. to 32.4 %o. The 96 hr LC50 value at salin...
