The fish fauna in the fish passage at the Ourinhos Dam, Paranapanema River
(SOC BRASILEIRA ICTIOLOGIASAO PAULO, 2012)
The composition and abundance of the fish assemblage were evaluated in the fish ladder of Ourinhos Dam, the newest dam (closed in 2005) in the cascade of dams constructed on the Paranapanema River. Samplings were carried ...
Interference of cage fish farm on diet, condition factor and numeric abundance on wild fish in a Neotropical reservoir
(2013-11-15)
Historically, the ichthyofauna of large Brazilian rivers has been subject to anthropogenic interference, such as impoundments. Currently, cage fish farming systems are a new source of impact on aquatic ecosystems. The ...

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 ...
An overview of the ongoing insights in selenium research and its role in fish nutrition and fish health
(Springer, 2017-12-01)
In the present review, the ongoing researches about selenium research in fish nutrition have been comprehensively discussed. Selenium research is getting popularity in fish nutrition as it is required for the normal growth ...
Insights into the concept of fish welfare
(Inter-research, 2007-05-04)
Fish welfare issues are predicated on understanding whether fish are sentient beings. Therefore, we analyzed the logic of the methodologies used for studying this attribute. We conclude that empirical science is unable to ...

Challenges in Assessing Fish Welfare
(Inst Laboratory Animal Research, Natl Res Council, 2009-01-01)
Descriptions of feeling states in nonhuman animals have relied on indirect evidence from empirical data. Assumptions that fish do not experience suffering lack evidence and in fact contradict a large body of indirect ...
Persistent organic pollutants (POPs) in fish from two coastal lagoons of the central Mexican Pacific

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 ...
