Strategies 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 کاملCulture of Mixed-sex Nile Tilapia with Predatory Snakehead
An experiment was conducted in eighteen 200-m2 fertilized earthen ponds at the Asian Institute of Technology, Thailand, from March through October 2000. This experiment was designed to assess the efficiency of snakehead (Channa striata) in controlling recruitment of mixed-sex Nile tilapia (Oreochromis niloticus) in ponds and to assess growth and production characteristics of Nile tilapia in mon...
متن کاملStudy on feasibility of Nile tilapia (Oreochromis niluticus) in Markazi province; Environmental capability and criteria
Unique biological characteristics of Nile tilapia (Oreochromis niluticus), including high fecundity, maturation at young ages, well-adapted to environmental conditions, and high resistance again stresses and pathogens, make it a good candidate for aquaculture. However, its potential ecological risks are the major challenges for the decision makers. This study was aimed to study on the feasibili...
متن کاملTerrestrial phosphorus limitation: mechanisms, implications, and nitrogen-phosphorus interactions.
Nutrient limitation to primary productivity and other biological processes is widespread in terrestrial ecosystems, and nitrogen (N) and phosphorus (P) are the most common limiting elements, both individually and in combination. Mechanisms that drive P limitation, and their interactions with the N cycle, have received less attention than mechanisms causing N limitation. We identify and discuss ...
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...
