Efeito do manejo alimentar utilizando Artemia em conserva no desenvolvimento do Platy (Xiphophorus maculatus)

Abstract

One of the biggest challenges for the creation of ornamental fish is feeding in the initial stage of development, so the use of Artemia salina is a great alternative in this stage of development. The present study aimed to evaluate the effect of canned artemia in the feeding of Platy (Xiphophorus maculatus). The experiment was carried out from six dietary protocols with different levels of inclusion of preserved artemia in the diet, T1 = (100% ration), T2 = (75% ration and 25% artemia), T3 = (50% ration and 50% artemia), T4 = 25% ration and 75% artemia), T5 = (100% artemia) and T6 = (Fasting). Zootechnical performance, color, enzymatic activity and antioxidant metabolism were evaluated. The treatments T5 and T4 obtained the best zootechnical performance, however there were no differences (P <0.05) between treatments for color and digestive enzymes. Among the antioxidant enzymes CAT and SOD, a difference (P> 0.05) was observed in the enzymatic activity of CAT. It was concluded that the T4 treatment was the best dietary protocol for the use of preserved artemia as a nutritional additive.
