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 کاملStrategies for Nile Tilapia (oreochromis Niloticus) Pond Culture
Different strategies for Nile tilapia (Oreochromis niloticus) culture in ponds with a series of progressive inputs were compared. The sequential experimental stages to increase fish production through intensification were: 1) triple superphosphate (TSP) only; 2) chicken manure only; 3) chicken manure supplemented with urea or urea and TSP; 4) urea and TSP; 5) continually supplemental feeding; 6...
متن کاملSemi-intensive Culture of Red Tilapia in Brackishwater Ponds
An experiment was conducted at the Asian Institute of Technology, Thailand, to investigate effects of fertilization rates and salinity levels on the growth of sex-reversed Thai red tilapia (Oreochromis sp.). The experiment was designed to test two fertilization rates (28 kg nitrogen and 7 kg phosphorus ha-1 wk-1, N:P = 4:1; and 14 kg N and 7 kg P ha-1 wk-1, N:P = 2:1) and three salinity levels ...
متن کاملDeveloping a Cell Culture System from Nile Tilapia (Oreochromis Niloticus, L.) Ovarian Tissue in Egypt
Cell culture from ovarian tissue of healthy female fingerlings Oreochromis niloticus was established with average weight of 20 to 30 gm/female. Three culture media were screened and tested: Leibowitz L-15), Minimum essential medium (MEM) and RPMI 1640 medium. Cells were maintained at 16, 27 or 30C for screening the favorable optimally incubation temperature. Culture medium was refreshed every 5...
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...
