Streptococcus in tilapia
Streptococcus species account for over half of all bacterial diseases in tilapia. The authors studied the ability of biotype-specific vaccines.

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.

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.

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