| الوصف: | Garra rufa are widely used in skin treatments at beauty and wellness institutes. This freshwater species is native from Eurasia and has a large distribution area, including river basins in Turkey and Iran. It has a high commercial value and arouse interest among fish farmers. Even so, G. rufa methods of production are still unknown. In fact, aspects that sustain a rapid and healthy growth of these fish need to be investigated, like an adequate daily dose and feeding frequency. This work aimed to establish: 1) the optimal feed dose per day, correspondent to the amount necessary for obtaining satiation, with a commercial granulated food; and 2) the optimal frequency of feeding for intensive production of G. rufa in Aquaculture. A total of 60 fishes underwent a 3 weeks acclimation period in laboratory, distributed by 6 aquaria, containing 10 fishes with similar body weight and length. The animals were initially fed with a dose correspondent to 10% of their body weight. This dose was gradually increased until complete satiation of the fishes. An optimal dose of 0.04 g fish-1 day-1 was found. Afterwards, the same fishes went through a 1 month experimental trial to evaluate the ideal feeding frequency. Fish growth was compared between feeding 0.2 g twice per day and 0.1333 g three times per day. Variations in size (total and fork length), plus body weight were evaluated at the end of the trial. One-Way ANOVA procedures revealed that the variations in weight and in fork length were similar between treatments, but the variation in total length was significantly higher with 3 daily feeding moments (p |
