Review: Use of organic acids, salts in fish diets
Published information on the effects of including organic acids and their salts at low concentrations in aquafeeds varies according to fish species and age, as well as the types and levels of organic acids and salts used.

GESIT tilapia: Indonesia’s genetic supermales
Tilapia quickly reach sexual maturity in culture, and unless controlled, the fish reproduce and offspring compete for food. All-male culture of tilapia is preferred because of their fast growth and larger average size.

Bioreactor technology for tilapia advances in Latin America
Early biofloc-based culture systems in tanks in Brazil have given way to commercial-scale bioreactors housed in greenhouses that utilize water fertilization regimes, high-protein feeds and salinity controls.

Study finds alternative anesthetic safe for tilapia fingerlings, breeders
Studies have proposed the use of anesthetics obtained from natural sources as alternatives to conventional chemicals. The authors recently evaluated the efficacy of the anesthetic Eugenol with a small sampling of red tilapia fingerlings and breeders.

Dissolved oxygen concentrations in pond aquaculture
Various studies suggest that maintaining minimum daily dissolved oxygen concentrations above 3 mg/L in channel catfish and penaeid shrimp ponds assures better feed consumption and growth.

Lipid, fatty acid requirements of tilapia
Dietary lipids are important sources of energy and the essential fatty acids needed by fish for growth and development.

Artificial incubation, hormonal sex reversal promoted tilapia boom
The tilapia production boom results from technology that combines artificial egg incubation and monosex fry production using hormonal sex reversal.

New recirculating systems offer efficient, responsible production
Recirculating systems, where probiotic, heterotrophic bacteria compete with pathogenic bacteria, can operate without antibiotics to produce tilapia and shrimp.
