This might be explained by three suppositions: Studies have investigated the fridericii of the parasite fauna of this fish in Brazilian rivers Feltran et al.
For this purpose, more reservoirs have been built in recent years, raising concern frideridi biological conservation. These effects can diminish human wellbeing by decreasing the services that ecosystems can provide for people Millennium Ecosystem Assessment The highest densities of young fish observed in year 7 appeared to have maintained themselves after 15 years following damming, and were similar to those observed for years 3 and 7.
August 29, ; Accepted: Many studies have been undertaken on the effects of dams on aquatic wildlife, in particular fish assemblages. Strategies and Tactics, Academic Press, London, p. The formation of parasite fauna and parasitic diseases frideici fish in water reservoirs.
However, how can dams affect the parasitic fauna of these fish?
Leporinus – Wikipedia
South American Monogenoidea parasites of fishes, amphibians and reptiles. Considering the biotic homogenization effect of dams, the present study hypothesizes that the Jurumirim Dam homogenizes the parasitic fauna of L. Fishing gear consisted of stationary nets with mesh sizes 3 to 14 cm, and trammel nets with mesh 6 to 9 cm between nonadjacent knots, set out for 24 hours at each sampling station.
Parasite infracommunities of Leporinus friderici: Longer or shorter spawning seasons must favor the permanence of a species in reservoirs, since the virtual reproductive losses of a shorter season are compensated by success in the survival of the young in the same or the subsequent season.
Breeding sites were identified as those with the largest concentration of individuals with mature and emptied gonads and the highest mean GSR values.
Two new species of Leporinus Agassiz, Characiformes: Global Ecol Biogeogr More than just fruderici river flow, damning a river simplifies the freshwater ecosystems and leads to conditions which change the parasite dynamic. Anostomidae with description of a new species from Suriname.
Fragmentation and flow regulation of the world’s large river systems. Relationships between the breeding season and sudden rise in river level, changes in current flow, water pressure, and occasionally chemical factors have been observed for L.
The parasite community of the host population from PR had the highest mean diversity index Shannon-Wiener and Simpson’s leporibus and, consequently, high distribution uniformity of parasite abundance Pielou index Table II. Comparison of four North Dakota impoundments and factors affecting the development of impoundment parasitofauna. The breeding season extended from September through April, although annual variation was seen in both reservoirs.
Academic Press, London, p. Metazoan parasites of the Chilean hake Merluccius gayi gayi as a tool for stock discrimination. To date, most efforts to quantify faunal homogenization in freshwater ecosystems has focused on fish assemblages.

Oliver and Boydp. Size-associated sexual dimorphism was observed, that is females dominated the longer length categories, and males the shorter. Redescription of Leporinus altipinnisa senior synonym of L. Summary page Point data Common names Photos.
Mechanisms of species coexistence: However, no data of the effects on the fish parasite community are available for this dam. Rio Grande do Norte.
