Restoration Effects of the Riparian Forest on the Intertidal Fish Fauna in an Urban Area of the Amazon River. [PDF]

ScientificWorldJournal, 2016
Urbanization causes environmental impacts that threaten the health of aquatic communities and alter their recovery patterns. In this study, we evaluated the diversity of intertidal fish in six areas affected by urbanization (areas with native vegetation, deforested areas, and areas in process of restoration of vegetation) along an urban waterfront in ...

Resource Partitioning between Two Piranhas (Serrasalmus gibbus and Serrasalmus rhombeus) in an Amazonian Reservoir. [PDF]

ScientificWorldJournal, 2017
The exploitation of resources by closely related species with similar niches may be mediated by differences in activity patterns, which may vary in nycthemeral scale and seasonal scale. Piranhas Serrasalmus gibbus and Serrasalmus rhombeus are Neotropical predators that occur sympatrically in many environments of the Amazon basin.

The introduced Arapaima gigas in the Bolivian Amazon: Trophic position and isotopic niche overlap with native species

Ecology of Freshwater Fish, Volume 32, Issue 4, Page 926-937, October 2023., 2023
Abstract Non‐native fish species may generate major ecological impacts on native assemblages. This study aims to assess the potential impact of the introduced Arapaima gigas on native fish assemblages in two oxbow lakes of the Bolivian Amazon. Stable isotope data were used to determine trophic position (TP) and isotopic niche overlap, to evaluate ...

Fisheries in a border area of the Moxos Lowlands (Bolivia) after invasion of Arapaima gigas

Aquaculture, Fish and Fisheries, Volume 3, Issue 2, Page 196-210, April 2023., 2023
We characterized fisheries in the area of the port city of Riberalta (upper Madeira River basin) and evaluated the contribution of an invasive species (Arapaima gigas) to the landings. A. gigas represented 57.6% of the overall economic value of fish in the region.

Balancing protein and energy in Nile tilapia feeds: A meta‐analysis

Reviews in Aquaculture, Volume 14, Issue 4, Page 1757-1778, September 2022., 2022
Abstract Farmed fish are increasingly grown in intensive and semi‐intensive systems where most nutrients are provided by formulated feeds. These are formulated to minimise costs and optimise growth, notably the rate of muscle protein synthesis (i.e., fillet). Protein synthesis depends on the availability of amino acids (i.e., protein) and energy. Thus,

Metacercariae of Austrodiplostomum compactum (Trematoda, Diplostomidae) in non-native fish species in Brazil: a possible explanation for the high rate of parasitic infection [PDF]

Anais da Academia Brasileira de Ciências, 2020
Metacercariae of Diplostomidae are widely distributed in America and may cause diplostomiasis, an ocular disease in fishes. The aim of this study is to report the occurrence of metacercariae of Austrodiplostomum compactum in Plagioscion squamosissimus ...
