Traceability program strengthens gamitana cultivation

The Rondonia aquaculture industry has experienced remarkable growth over the past five years through the project for the "Traceability of Tambaqui of Rondonia." This initiative began in 2005 with the aim of raising fish obtained from known genetic breeding. While statistics indicate a production of 5.5 million fingerlings in the state five years ago, in 2010, only one producer in the municipality of Pimienta Bueno provided the same amount, reports Globo Rural.

Farmers suspected that the consanguinity or the degree of relatedness between tambaqui fingerlings of gamitana or tambaqui (Colossoma macropomum) of common descent, produced in the laboratories of the state, would be very high. "The consanguinity should not be random, because it can cause problems, including the risk that the fry are born with abrasions on the lower back and more susceptible to disease," said Danilo Streit, a consultant at Sebrae.

According to Streit, the suspicion of the producers could not be verified, which led the research team from the PeixeGen Research Center of the State University of Maringá (UEM), Paraná, to assess the genetic variability of commercial stocks in Rondonia. "The results showed high genetic variability within these schools of tambaqui, although they come from the same origin," said the researcher. Read more...
