Natural and artificially-induced habitat complexity and freshwater fish species composition
(Blackwell Publishing, 2005-02-01)
The effects of habitat complexity, induced by construction of artificial reefs, on the fish assemblages in the Barra Bonita reservoir, Brazil, and in the lotic zone immediately below the dam were studied. Four artificial ...
Distribution patterns of two species of Corynosoma (Acanthocephala: Polymorphidae) in fishes from Southwestern Atlantic
(Springer, 2019-08)
Corynosoma australe and C. cetaceum are the most frequently reported acanthocephalans in fish from the Argentine Sea, particularly in central and northern areas. Their definitive hosts are otariids and odontocete cetaceans, ...
Effects of a Dam Reservoir on the Distribution of Heavy Metals in Two Chilean Native Freshwater Fish Species
(Springer, 2016)
In order to determine the effect of a dam on metal concentrations in riverine fish species, we studied fish inhabiting the influent (Cachapoal River) and effluent (Rapel River) of the Rapel Reservoir in central Chile. Heavy ...
The fish fauna in tropical rivers: The case of the Sorocaba river basin, Sao Paulo, Brazil
(Revista De Biologia Tropical, 2003-09-01)
A survey was carried out on the fish species in the Sorocaba. River basin, the main tributary of the left margin of the Tiete River, located in the State of Sao Paulo, Brazil. The species were collected with gill nets. ...
Life history, population structure, and movement of gobid fishes in tropical urban and non-urban watersheds

Fish diversity in the cascade of reservoirs along the Paranapanema River, southeast Brazil
(Soc Brasileira Ictiologia, 2018-01-01)
The Paranapanema River is a major tributary of the upper Parana river basin. Eleven hydropower dams regulate its main course, but no study has investigated fish diversity in these impoundments at the basin-scale. The present ...
Marine fronts are important fishing areas for demersal species at the Argentine Sea (Southwest Atlantic Ocean)
(Elsevier Science, 2014-01)
The high primary and secondary production associated with frontal systems attract a diversity of organisms due to high prey availability; this is why a strong relationship between fronts and pelagic fisheries has been shown ...
Two 5S rDNA arrays in Neotropical fish species: is it a general rule for fishes ?
(Kluwer Academic Publ, 2001-01-01)
In this paper we describe Southern blot hybridization results probed with 5S rRNA genes for several Neotropical fish species representing different taxonomic groups. All the studied species showed a general trend with the ...
