Resumen

NEU, D.H. et al. Processing of diet for larvae of Pimelodus britskii. Arch. zootec. [online]. 2011, vol.60, n.231, pp.809-812. ISSN 0004-0592.  http://dx.doi.org/10.4321/S0004-05922011000300068.

This study aimed evaluate the influence of food processing in diet on development of larvae of Pimelodus britskii. Seventy five larvae were assigned in a completely randomized design to 15 aquariums of five liters at a density of one larva per liter. The diets were processed and supplied as mash, paste and extruded ground. The larvae were feeding to apparent satiation for a period of 30 days, four times daily: 8, 11, 14 and 17 h. The parameters of water (dissolved oxygen, pH and conductivity) were measured once a week. There were not differences in performance for final weight, and survival of larvae. For the average final length, the ground extruded diet was better than the mash diet (p<0.05) but not different from the pasty diet. These results indicate that processing of the feed influence the performance of the Pimelodus britskii in the initial phase. Therefore is recommended the use of ground extrused diets to achieve higher final length of animals.
