A tilapicultura no estado do Pará, Amazônia.

The objective of this study was to analyze the history and current status of tilapia farming in the state of Pará. Field observations and interviews were carried out with government agency technicians and fish farmers, from January 2014 to December 2016. It was found that the tilapia was brought to Pará State in the 1970s and, currently, the Nile Tilapia (Oreochromis niloticus) is the only species produced. The minimum slaughter weight of 200 grams, marketing in whole form to the detriment of the filleted fish in the retail market, and the absence of sex reversal initiatives are peculiar features of Pará state’s tilapia farming, as compared with that of the other Brazilian states.
