The Effect of Initial Stocking Density on Growth and Survival of Pike-perch Fingerlings Reared under Intensive Conditions

The effect of different daily feed rations on the growth, condition, survival and feed conversion of juvenile pikeperch (Sander lucioperca) reared with dry feed in net cages

“…They did not find a significant effect of density on the growth, cannibalism and feed conversion. On the other hand, the highest survival rates were observed under the highest stocking densities (Molnár et al 2004). In another experiment, Zakęś (1999) found that temperature did not significantly influence the growth, but highly effected the survival and cannibalism when applying 22 or 24°C ambient temperatures.…”

“…Hilge (1990) was the first to rear pikeperch on dry feed and suggested this species as a candidate for intensive culture. Zakęś (1997) and Molnár et al (2004) studied the effect of stocking density on cannibalism, survival, growth and feed conversion of pikeperch fingerlings. They did not find a significant effect of density on the growth, cannibalism and feed conversion.…”

“…These rearing experiments were carried out in aquaria and fish tanks (Hilge 1990;Zakęś and Szczerbowski 1995;Zakęś 1999;Molnár et al 2004;Zienert and Heidrich 2005).…”

Densidade de estocagem no crescimento, composição e perfil lipídico corporal do jundiá

“…Alguns trabalhos demonstram que, em maiores densidades, os peixes são mais agressivos na busca e ingestão do alimento, resultando em maior sobrevivência, sem redução de crescimento, consumo e conversão alimentar (MOLNÁR et al, 2004;ROWLAND et al, 2004). Entretanto, também podem ocorrer alterações no comportamento e pior utilização do alimento, resultando em mortalidade e crescimento reduzido (MONTERO et al, 1999).…”
