The Secretariat of Agricultural Protection, from the Ministry of Agriculture, Livestock and Supply (MAPA) of Brazil authorised the registration of the first vaccine for use in commercial fish in the country.
The authorisation is achieved through the joint work between the Ministry of Fisheries and Aquaculture (MPA) and MAPA.
MPA highlighted that the technical support provided for the analysis of specific processes for aquaculture allowed the Ministry of Agriculture to be able to act more quickly in the analysis of specific veterinary products for the area.
The vaccine will be used to protect tilapia from the Nile River, one of the most widely farmed species in Brazil, against the infection caused by Streptococcus agalactiae bacteria. This bacterium causes severe syndromes such as septicemia and encephalitis, and infections of the central nervous system of tilapia in the fattening period, especially during the warmer months.
This bacterium usually affects tilapia farmed in cages and causes a high mortality rate, with considerable economic loss for producers.
The scientific studies conducted by universities in Brazil showed that this disease appears in several states, such as Santa Catarina, Paraná, Rio de Janeiro, Espírito Santo, Minas Gerais, Bahia, Pernambuco, Paraíba and Alagoas, among others.
Director of Monitoring and Control from the Department of Fisheries and Aquaculture of MPA, Henrique Figueiredo, stressed the new vaccine is a definite improvement in aquatic health.
"This vaccine represents an alternative for farmers as an aid to fight and control this important disease in tilapia farming," he said.
The vaccine that has just been approved will begin to be traded on the Brazilian market shortly.
