Descrição: dc.descriptionThe present study aimed to evaluate two different methods of artificial reproduction induction, and characterize the embryonic development ofSalminus hilarii. Different than observed for other tropical fish species, artificial reproduction induction followed by hand-stripping of gametes was considered unfeasible forS.hilarii, as no gamete fertilization was observed. However, females that were induced and spawned naturally presented a fertilization rate of 65.64 +/- 0.54%. With a mean temperature of 26.20 +/- 0.90oC it was possible to clearly distinguish a large perivitelline space at 14 min after fertilization (AF) and at 49 min AF more than 50% of the embryos presented two blastomeres, and these cleavages occurred until 1 h 54 min AF. The gastrula phase was characterized at 3 h 56 min AF, and blastopore closure was observed at 8 h 31 min AF. At 9 h 1 min, organogenesis started, with a clear distinction of the yolk mass, embryonic axis, cephalic and caudal regions; at 11 h 51 min AF the embryos already had advanced segmentation and a free tail. Total hatching occurred at 21 h 17 min and after opening the mouth, which occurred at 33 h 9 min, the larvae ofS.hilariipresented a strong and characteristic cannibalism. This information can be considered fundamental to improvingS.hilariiproduction in captivity and for collaboration with a conservation programme in the upper Tiete river basin.-
