Niquim Lophiosilurus alexandri is an endemic fish from the San Francisco River and was harmed after the damming up of the waters, being one of the most valuable fish in the Sub-medium region and presenting potential for pisciculture. This study aimed to evaluate its growth during the initial ontogenic phases, under different luminosity conditions and types of food, supplying technical subsidies to the pisciculture and to the species propagation programs. The experiment was conducted in incubators with luminosity at 100% (L), 50% (ML) and 0% (SL) with four repetitions and two alimentary criteria: plankton+ration and Dendrocephalus braziliensis+ration. The variance analysis (ANOVA) was carried out to verify the effect of different light conditions and food on the Niquins' length. The Tukey test (P
