Resumo: The present study aimed to evaluate the aquaculture potential in Southern Brazil for two species of freshwater fish: dourado, Salminus brasiliensis and jundiá, Rhamdia quelen. Growth, feed conversion, growth differences between males and females, resistance to handling and survival rate were evaluated. Fingerlings of the two species were stocked in earthen ponds at two different locations in the State of Santa Catarina: Santo Amaro da Imperatriz (SA) and São Carlos (SC). Fish were fed commercial diets twice a day to apparent satiation. After 365 days (jundiá) and 605 (dourado) days, jundiá presented a daily weight gain (DWG) of 1.00 and 1.97g and feed conversion of 1.85 and 1.78 at SA and SC, respectively, whereas for dourado, the DWG was 0.46 and 0.51 and feed conversion was 3.52 and 3.82 at SA and SC, respectively. At SA, differences were detected between males and females for growth, condition factor and gonadosomatic index. Stocking density, pond size and sexual ratio are discussed for both species.

Para tanto, a velocidade de crescimento, conversão alimentar, diferença de crescimento entre machos e fêmeas, resistência ao manejo e sobrevivência destas espécies foram avaliadas. Alevinos destas duas espécies foram estocados em viveiros de terra, em dois municípios de Santa Catarina: Santo Amaro da Imperatriz (SA) e São Carlos (SC). Estes foram alimentados com dietas comerciais, duas vezes ao dia, até a saciedade aparente. Após 365 (jundiás) e 605 (dourados) dias, os jundiás apresentaram um ganho em peso diário (GPD) de 1,00g e 1,97g e conversão alimentar de 1,85 e 1,78, em SA e SC, respectivamente, enquanto os dourados um GPD de 0,46g e 0,51g e conversão de 3,52 e 3,82, em SA e SC, respectivamente. Em SA, foram detectadas diferenças em GPD, fator de condição e índice gônado-somático entre machos e fêmeas. Fatores como densidade de estocagem, tamanho de viveiro e proporção sexual são discutidos para as duas espécies.Editora da Universidade Estadual de Maringá2008-04-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/180610.4025/actascianimsci.v26i3.1806Acta Scientiarum.
