Effect of daily Artemia nauplii concentrations during juvenile production of Lophiosilurus alexandri
Keywords:
pacamã, prey concentrations, feeding managementAbstract
The aim of this study was to investigate different daily Artemia nauplii concentrations during juvenile production of pacamã, Lophiosilurus alexandri. Six different daily Artemia nauplii concentrations (100, 400, 700, 1,100, 1,400, and 1,600 nauplii larvae-1) were tested during 15 days of feeding. The higher growth (weight and length) and lower water quality (higher ammonium ion levels) were registered to the higher initial daily Artemia nauplii concentration. Survival between 90.9 and 99.1% was not influenced by Artemia nauplii concentrations. Different Artemia nauplii concentrations provided high survival and avoided cannibalistic behavior, and initial concentrations of 1,600 nauplii larvae-1 provide higher growth in L. alexandri larviculture.
