Experiments were conducted to assess the effects of polyculture on tilapia growth and to evaluate African catfish (Clarias gariepinus) as a predator control for unwanted tilapia offspring in a polyculture system. Three treatments were tested using nine 200 m earthen ponds. Ponds were stocked with male tilapia in treatment 1 (Tl), mixed sex tilapia in treatment 2 (T2), and mixed sex tilapia and ...

Natural selection and selective breeding for genetic improvement have left detectable signatures within the genome of a species. Identification of selection signatures is important in evolutionary biology and for detecting genes that facilitate to accelerate genetic improvement. However, selection signatures, including artificial selection and natural selection, have only been identified at the...

Physicochemical parameters of pasta enriched with tilapia (Oreochromis niloticus) flour were investigated. Five formulations were prepared with different concentrations of tilapia flour as partial substitute of wheat flour: pasta without tilapia flour (PTF0%), pasta with 6% (PTF6%), 12% (PTF12%), 17% (PTF17%), and 23% (PTF23%) of tilapia flour. The formulations were assessed for proximate compo...

Introduction of sahar in cage-cum-pond integration system of mixed-sex Nile tilapia was evaluated using 15 outdoor cemented ponds of 24 m2 (4.9m × 4.9m) size with 1.25 m water depth placing a cage of 1.2m× 1m × 1m size holding 1 m3 water at the center of each pond at Institute of Agriculture and Animal Science (IAAS), Rampur, Chitwan, for 158 days. The experiment was conducted in a completely r...

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...

for cage culture. Species which have been researched and successfully reared in cages in the southeastern region of the U.S. include: catfish, trout, tilapia, striped bass, red drum, bluegill sunfish, crappie, and carp. Other species may be suitable for cage culture but research has lagged behind other aquaculture research in recent years. Interest in cage culture has been revived as an alterna...

This report examines samples of farms from Honduras departments that have and do not have tilapia ponds as part of their farming systems. Data were obtained through personal interviews with 128 farmers, including 64 tilapia producers, in five departments: Olancho, Intibuca, El Paraíso, Francisco Morazán, and Santa Bárbara. To obtain information about farms without tilapia, farmers were selected...
