ABSTRACT

The mass rearing of goldfish larvae and juveniles was carried out under controlled conditions. Two of main aquacultural factors: food regime and stocking densities were studied. During rearing larvae and juvenile goldfish in captivity, dry food can not be used as only one kind of offered food. Initially, fish fed only with this food grew slower and during rearing the mortality significantly increased. After few weeks of rearing, all fish from these groups were died. It was in contrast with fish survival in groups fed with mixed food. As an optimal stocking density from tested in this work, the 1700 specimen per m³ was chosen, with fish survival over 85%. After six weeks of main rearing, the goldfish were in market size.

Key words: goldfish, juvenile, larvae, mass rearing.
