Duration of co-feeding on the Nishikigoi Cyprinus carpio larvae during weaning from live to inert food in an indoor system

Abstract: This study aimed to evaluate the effects of the co-feeding period (C) on the survival and growth of larvae of nishikigoi Cyprinus carpio, during the weaning period from live to inert food. A total of 1680 larvae with initial weight of 1.33 ± 0.12mg and initial length of 6.0 ± 0.33mm were used. The inert diet used was a commercial ration with 55% crude protein and the live food was the newly hatched nauplii of Artemia franciscana. The experiment was conducted following a completely randomized design with six tr… Show more

“…The low survival averages observed in these two treatments are probably related to the amount of food provided to the larvae, a fact that probably increased intraspecific competition, generating increased mortality. Contrary to what was observed in this experiment, Fosse et al (2018) observed survival of 97.86 ± 1.84% in the cultivation of ornamental carp larvae, using only 150 Artemia nauplii per larvae, but this author has adopted the density of 7 larvae L -1 and does not make clear whether it was carried out proportional correction regarding the number of nauplii offered. In this experiment was used the density of 20 larvae L -1 , and correction of Artemia nauplii quantity offered according to the observed mortality.…”

“…In present experiment it was observed that the carp larvae submitted to the proposed food protocol for treatment 1 were able to feed with powder meal from day 1 of exogenous feeding, as observed by other authors (Bryant & Matty, 1981;Fosse et al, 2018), but presented results of morphological parameters lower than those observed for the other treatments. Differing from what observed in this experiment, some authors working with other inert food formulations in the larviculture of the common carp, achieved good results in morphological parameters using a few basic ingredients, such as yeast and casein (Carvalho et al, 1997;Cahu et al, 1998).…”
