Abstract

The aim of this study was to evaluate the zootechnical performance and chemical composition of jundia juveniles Rhandia voulezi fed with mash, pelletized and extruded diets and cultivated in cages. One hundred and fifty fish were distributed in fifteen cages (0.20 m³), arranged in cages (5m³), in the hydroelectric plant of Governador José Richa, in Iguaçu River (Paraná-Brazil). The fish were fed five times a day, with mash, pelletized and extruded diets, containing 30% of protein and 3250 Kcal/kg of digestible energy/kg. At the end of 60 days, significant differences (p<0.05) were observed on fish performance. The fish that were fed with pelletized diet, presented higher average of final weight (44.08g), final length (16.51cm) and weight gain (36.65g).  The different processes did not influence fish survival. The averages of protein and mineral matter of carcass chemical composition did not differ statistically (p<0.05), while the values of humidity and lipideos presented differences among treatments. The highest average of lipideos (8.59%) was observed in peletized diet. The mash diet provided fish with lower lipideo (5.45%) and higher humidity (75.98%) rates. A pelleted diet is most suitable for juvenile catfish R. voulezi cultivation in cages.
