Efeito da densidade de estocagem do quinguio, Carassius auratus L., 1758 (Osteichthyes, Cyprinidae), em suas fases iniciais de desenvolvimento


, : Efeito da densidade de estocagem do quinguio, Carassius auratus L., 1758 (Osteichthyes, Cyprinidae), em suas fases iniciais de desenvolvimento. Acta Scientiarum Universidade Estadual de Maringa 24(2): 527-532

This experiment aimed to evaluate the influence of stocking density on the goldfish, Carassius auratus (Osteichthyes, Cyprinidae) development, during its initial phases. 300 fry (Lt.: 7.00 mm) were distributed in 20 12-liter aquariums. The experimental design was entirely randomized, with four treatments (0.50; 1.00; 1.50 and 2.00 fry/liter) and five replications. Food consisted of Antemia sp nauplii (supplied proportionally to density) and rations with 40% raw protein, given ad libitum.
