The authors conducted a study to evaluate whether tilapia infected with Gyrodactylus were more susceptible to Streptococcus iniae. The research found that fish with a solo infection of Gyrodactylus or Streptococcus had less than 7 percent total mortality.

Saudi Arabia has a growing aquaculture industry that farms mainly tilapia, but also shrimp, grouper, sea bream, rabbitfish and mullet. Although aquaculture is a major source of supply for fresh fish, it has not grown fast enough to meet the country’s growing demand.

In a trial, a novel dietary vegetable oil blend was able to totally replace fish oil in tilapia diets without negatively impacting growth performance.

Much of Brazil’s expanding tilapia aquaculture takes place in floating cages with sturdy frames and nets made from plastic-coated steel or polypropylene.

Determining dietary requirements for tilapia requires precise formulation. Individual amino acids must be considered to establish well-balanced 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.

In research on alternatives to formalin treatment to control Ich infestation, the authors performed a study that compared the immune responses of Nile tilapia and red tilapia against the parasite.

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.
Health & Welfare
The effective control of tilapia health depends on integrated management that considers all factors, including species, the environment, pathogens present and farm management practices.

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.

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.

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.

Dietary lipids are important sources of energy and the essential fatty acids needed by fish for growth and development.

The tilapia production boom results from technology that combines artificial egg incubation and monosex fry production using hormonal sex reversal.
Responsibility
Recirculating systems, where probiotic, heterotrophic bacteria compete with pathogenic bacteria, can operate without antibiotics to produce tilapia and shrimp.

Tilapia production in Asia focuses on either fresh whole fish or larger frozen whole fish or fillets, depending on farm size, cash flow and other factors.
