Microcystin-LR in Brazilian Aquaculture Production Systems
(Water Environment Federation, 2010-03-01)
The growth of aquaculture production systems, mostly the sport-fishing kind, coupled with a lack of control, brings about concerns on the quality of water and food produced. The current paper determines which factors may ...
Artificial reefs and their effects on fish assemblages in a Brazilian reservoir and Tailrace
(2002-12-01)
In this paper, we evaluate the effects of artificial reefs on fish assemblages in a hypereutrophic reservoir and in the lotic zone immediately below dam. Fish diversity was highest in the lotic zone relative to the reservoir. ...

Eutrophication effects on fatty acid profiles of seston and omnivorous fish in tropical reservoirs
(2021-08-10)
It has been postulated that eutrophication causes replacement of n3 highly unsaturated fatty acids (n3 HUFA) rich taxa, such as Bacillariophyta, Cryptophyta and Dinophyta, with taxa poor in these fatty acids (FA), such as ...
Influence of the bacterioplankton community of a tropical eutrophic lagoon on the bacterial community of its neighbouring ocean
(SPRINGER, 2010)
The Rodrigo de Freitas lagoon (RFL) is a tropical eutrophic coastal ecosystem located in the urban area of Rio de Janeiro, Brazil. This environment consists of freshwater but has communication with the ocean through a ...
Microplankton Dynamics Under Heavy Anthropogenic Pressure: the Case of the Bahía Blanca Estuary, Southwestern Atlantic Ocean
(Elsevier, 2015-06)
Quantifying biotic feedbacks in response to environmental signals is fundamental to assess ecosystem perturbation. We analyzed the joint effects of eutrophication, derived from sewage pollution, and climate at the base of ...
Epipelon, phytoplankton and zooplankton responses to the experimental oligotrophication in a eutrophic shallow reservoir
(2020-08-01)
Epipelon can contribute to the maintenance of shallow lake oligotrophication. Herein, we simulated oligotrophication by diluting eutrophic water and evaluated epipelon biomass and structure and potential relationships with ...
Mapping the coloured dissolved organic matter absorption coefficient in a eutrophic reservoir using remotely sensed images
(2018-10-02)
Dissolved organic matter (DOM) has 3 major sources: (1) autochthonous or surface water-derived of algal origin, (2) allochthonous or terrestrial material from soils, and (3) synthetic organic substances of man-made or ...
