Abstract:
The Loricariids, known as cascudos or plecos stand out for the wide variety of shapes and patterns, which have attracted great interest from national and international aquarium market. The Hypancistrus zebra fits perfectly, though the species is in a vulnerable position due to over-exploitation in the natural environment, forcing the authorities to veto the trade of the species. Thus for the species to return to the market, reproductive technology and management in captivity need to be further studied in order to create creating protocols for conservation of the species in the wild and release of captive bred and cultivated species. Thus, the present study aimed to determine an stocking density for H. zebra juveniles. 4 stocking densities were used (0.25 g fish per liter, 0.50 g L-1, 1.00 g L-1 and 2.00 g L-1.) In aquariums of 30 liters useful during 60 days containing 3 repetitions each, fed the will with frozen adult artemia. The results showed that no significant difference in performance and survival in all densities.
