Dietas alimentares para Hypancistrus sp. em laboratório

Abstract

The aim of this study was to evaluate different feeding strategies in the species Hypancistrus sp. (14.22 ± 6.19g and 7.436 ± 0.863 cm) in the laboratory. 5 fishes/aquarium aquariums (60 cm long x 45 cm high x 40 cm wide) were distributed in 15 experimental units with a useful volume of 76 L each, in a recirculation system in the laboratory) and TPC (pasty ration + feed with the purpose of accentuating the color of the fish) during a period of 80 days. For specific growth rate, the acaris from the TP, TPC and TA treatments (p<0.05) had better performance. The fishes from the TC and TA treatments showed a better correlation between weight and length, and also the relative condition factor indicated well -being of the fishes submitted to different diets. The other zootechnical parameters evaluated did not differ significantly for the fish of the different treatments (p>0.05). A natural reproduction was registered for acaris fed with the specific ration for coloration. It is concluded based on the results that the most suitable for the species Hypancistrus sp. it is fed with a dry diet (garlic base) associated with a wet diet (pasty ration).
