Global importance of Amazonian freshwaters

Frontiers in Ecology and the Environment, Volume 23, Issue 10, December 2025.
Amazonian freshwaters have large influences on regional and global climate, harbor remarkable and unique species, and are vital to human society. Nevertheless, as compared to their terrestrial counterparts in the Amazon, these freshwaters have received less attention from the international conservation community.

Genetic parameters and response to selection for growth in tambaqui

Animal, 2020
Although the tambaqui (Colossoma macropomum) is the most cultivated native fish species in Brazil, estimated breeding values for growth traits are rarely used for selection of superior individuals in commercial fingerling production. This study aimed to estimate the (co)variance components of growth traits.

Enzimas digestivas exógenas na alimentação de juvenis de tambaqui Exogenous digestive enzymes in tambaqui juvenile feeding

Pesquisa Agropecuária Brasileira, 2006
O objetivo deste trabalho foi avaliar o efeito da adição na ração das enzimas digestivas exógenas amilase, lipase e protease sobre o desempenho de tambaqui, em três experimentos independentes. Em cada experimento foi avaliado o efeito da inclusão de uma enzima na ração em diferentes porcentagens: 0,0, 0,05, 0,1 e 0,2%, cada uma com quatro repetições ...

Threshold responses of floating meadow fish communities to floodplain forest cover in the lower Amazon River

Conservation Biology, Volume 39, Issue 6, December 2025.
Abstract Forest cover is positively associated with fish biomass and fisheries yield in the Amazon River floodplain, and many species enter flooded forests to feed, spawn, or seek refuge from predation. Floating macrophyte beds, known as floating meadows, in Amazon floodplains support high fish diversity and serve as nursery habitat for many fishes of ...

Temporary fat storage, an adaptation of some fish species to the waterlevel fluctuations and related environmental changes of the Amazon river

, 1985
Analysis of Amazonian freshwater fish exhibited great differences in water- and fat content. Migratory species which deposit huge amounts of eggs in a single spawning act accumulate at high water-level great amounts of fat in various parts of the body ...
