Characterization of unit producing fingerlings of rio grande of South, Brazil

The production of fingerlings is an important link in the production chain of fish farming in the state of RS, generating income and employment. The aim of this study was to characterize the units producing fingerlings state of Rio Grande of South (RS). To both, was drafted a questionnaire consisting of open-ended questions and close-ended. Sixteen out of eighteen hatcheries answered the form between September 2011 and February 2012. The analysis shows that silver catfish fingerlings (Rhamdia sp.) and grass carp (Ctenophynigodon idella) are the most produced by hatcheries visited.  It was observed that there is no control of the quality and origin of animals are used as breeding stock. Therefore, it is suggested to carry out a breeding program for the development of improved strains for increased productivity of the species that are used in fish farming in the state. These observations reinforce the need of joint efforts among research, extension and government, in order to contribute to the improvement of this productive sector of the state of RS. However, the application of new production technologies and management that seek to reduce the costs of production must take into account the local reality of hatcheries.
