Tilapia production in Asia
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.

Streptococcosis in tilapia
Tilapia infected with streptococcosis pathogens exhibit similar clinical signs, including lethargy, abnormal swimming and lack of appetite.

Tilapia culture in Ecuador
Tilapia culture in Ecuador is marked by vertically integrated companies that manufacture their own feeds and practice polyculture with Pacific white shrimp.

Tilapia culture in Lake Kariba, Zimbabwe
Lake Kariba, on the Zambia-Zimbabwe border, has no industry, few people, high-quality freshwater and an average year-round temperature of 27 degrees-C, all features that can support aquaculture.

Effects of varied dietary lipid sources tested in tilapia study
A study of Nile tilapia provided feed with varying dietary lipid sources found that fish fed a diet with beef tallow exhibited poorer survival and growth performance than fish fed diets with plant oils, fish oil, or combinations of oils and tallow.

Quality control measures improve tilapia production chain in Latin America
The experiences of tilapia farmers combined with effective quality control programs implemented by government have improved production in Mexico, Colombia, Ecuador, Peru and other Latin American countries.

Bath immersion, booster vaccination strategy holds potential for protecting juvenile tilapia
In a study, vaccination of juvenile tilapia by bath immersion followed by two booster vaccinations stimulated specific antibody responses and protection against S. iniae challenge.

Disease management in tilapia
Tilapia in culture are affected by bacterial, viral and parasitic pathogens. Disease impacts vary depending on both environmental and biological factors.

Bacterial, chemical residues impact tilapia quality
Both bacterial pathogens and chemical residues can affect the quality of farmed tilapia products. In production systems, Vibrio bacteria quickly proliferate following disease outbreaks.

GIFT tilapia: Technology for successful selected strain continues
Selective breeding across multiple generations of Nile tilapia representing varied geographic populations yielded the “genetically improved farmed tilapia,” or GIFT tilapia, in the late 1990s.

Expanding tilapia supply meets growing global market
Global tilapia production and consumption growth has mirrored the species' versatility. The fish will remain integral to rural aquaculture development.

Food safety, quality control in tilapia products
The most important quality issue for tilapia is the presence of off-flavors that derive from cyanobacteria and actinomycetes, which can be addressed by depuration.

Nucleotide supplementation improves survival, production of white shrimp, tilapia in trials
Several trials in Ecuador and Thailand showed that nucleotide supplementation in feed can improve growth and survival in shrimp and tilapia production.

Tilapia vaccines: important disease prevention, biosecurity tools
Tilapia vaccines can protect the fish against infectious diseases by providing pathogen-specific acquired immunity that prevents recurring infections.

Periphyton-based tilapia-prawn polyculture
In periphyton-based aquaculture, the various invertebrates that colonize the hard substrates provided in ponds supplement artificial feed.
