Bacterial diseases cause granulomas in fish
Granulomas in diseased fish often indicate infections by bacteria. External signs range from ulcers and emaciation to lethargy or no signs at all. Internally, gray or tan foci present in organs and can coalesce with severe inflammation.

Tilapia production using biofloc technology
Biofloc systems enable more intensive tilapia production. The fish adapt to the conditions within biofloc systems and grow well by utilizing the bioflocs as a feed source.

Parasitism enhances susceptibility to bacterial infection in tilapia
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.

Tilapia aquaculture in Saudi Arabia
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.

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.

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.
