Laboratory fish ecology
This working group is dedicated to studying the assemblages of fish from environments and their relationship with the characteristics of the ecosystem and its social environment. The demographic characteristics of the groups of fish from lagoons, streams and the Río de La Plata and the anthropic impact on the same in pursuit of achieving progress for their conservation, management and use.
RESEARCH ACTIVITIES
In the laboratory we carry out both basic and applied research in the ecology of fish with an emphasis on the structure, function and dynamics of the populations, as well as on aspects related to their diet, reproduction and growth. We analyze the responses of fish stocks under natural conditions and under different degrees and types of land uses and pollution.

August 2024 - FISH MORTALITY IN THE RÍO DE LA PLATA
To better understand the characteristics of this mortality, it is important to highlight that the species affected (tarpon, pacucito, armado, catfish, bogas, dorado, pirá-pitá and moray eels, among others) inhabit the La Plata Basin and find their limit of distribution in the Río de la Plata, with the default temperature being the variable that limits its latitudinal scope. Another characteristic is that the fish affected were mainly youth, a fact linked to the exceptional success of the breeding event of spring 2023 that the mentioned species had due to the exit from the exceptional drought that the basin went through.
