FIGURE 2 | Alternative schematic representations of spawning in Prochilodus lineatus. A. Schematic drawing of spawning moment of Prochilodus lineatus (=Prochilodus scrofa), according to Godoy (1975), whom described that males, positioned in the center of the river channel, performed distinctive sounds, possibly attracting females (figure drawn by Josiane Ribolli and Dennis Fernando Moreno, inspired from the original by Godoy, M. P, 1975, fig. 153, p.684); B. Hypothetical schematic representation of reproduction and spawning of P. lineatus in the wild according to direct observations made by Evoy Zaniboni-Filho (personal communication). The exhausted mature female is marked with an asterisk. Figure drawn by Josiane Ribolli and Dennis Fernando Moreno.
