Abstract: Artificial reproduction and gamete fertilization were evaluated in Salminus hilarii wild and domesticated broodstocks. Wild and domesticated broodstocks were artificially induced to reproduction using a carp pituitary treatment. Four groups were considered: Group 1 (G1), fish caught in the wild maintained for three years in the same conditions as the domesticated broodstocks and spawned naturally; Group 2 (G2), broodstock born and raised in captivity and spawned naturally; Group 3 (G3), wild broodstocks, which… Show more

“…The young can also be threatened by cannibalism from their parents after re-absorption of their yolk sacs: because of limited space in the aquarium, they are not able to move out of the reach of the parents, who start perceiving them as live food. However, there was no cannibalism involving the young eating each other, a characteristic of other species such as Percidae, Siluridae (Smith & Reay, 1991;Caneppele et al, 2009) or Salminus hilarii (Honji et al, 2011).…”

“…These two species were collected in lotic stretches of the inventoried rivers. It is important to emphasize that S. hilarii can be used as an environmental indicator (Honji et al 2011). …”

“…The individuals of the species are distributed in several South American river basins: Paraná, São Francisco, some rivers in the Amazon basin, Tocantins, and Orinoco (Lima et al, 2003). It is considered as a rheophilic fish species whose individuals migrate during the reproductive period, coinciding with warmer waters and rainy seasons (Agostinho et al, 2004;Olarte and Taphorn, 2006;Takahashi, 2006;Villares-Júnior et al, 2007;Honji, 2007;Honji et al, 2011).…”

“…(Graça and Pavanelli, 2007;Honji, 2007;Honji et al, 2011). So, the importance of knowledge about feeding habits of S. hilarii is evident, since this species is one of those ones heavily threatened in South America.…”
