Feed transition in larval rearing of bocudo, Steindachneridion scripta (Pisces, Pimelodidae), using Artemia spp. nauplii and artificial diet
Feed transition of Steindachneridion scripta larvae was investigated using seven treatments in which the reference diet, Artemia spp. nauplii, was totally substituted for a 56% crude protein artificial diet in two-day intervals. Initially, all treatments were fed with Artemia spp. nauplii and, subsequently, during the transition period, feed was equally composed by Artemia sp. nauplii and artificial diet. Everyday, one of the treatments began the feed transition, which was implemented between the second and the eighth days of culturing. Two treatments were used as control: one exclusively fed Artemia spp. nauplii and another only with artificial diet. Total weight, total length, and survival rate were not influenced by the day in which feed transition was implemented (P>0.05), and their mean values (± SD) were 31.1±25.0mg, 13.3±1.5mm and 58.8±12.0%, respectively. This suggests that Steindachneridion scripta larvae adapted well the transition to artificial diet.
