The second suggestion cannot be totally discarded, since fish species have specific tactics for spawning and development of the young and information about these behaviors is sparse, not only for L. More than just controlling river flow, damning a river simplifies the freshwater ecosystems and leads to conditions which change the parasite dynamic. In spite of the fact that the present fish community there is dominated by species of lentic environments, lotic species such as the dourado, piapara, and piau leporihus still caught by the commercial fishery of Itumbiara Godinho, friderrici Moderate vulnerability 38 of Statistical differences in infracommunity diversity Shannon-Wiener index among host populations from the three tributaries were tested using the Kruskal-Wallis test Zar How environmental stress affects the impact of parasites.
