Tambaqui growth and survival when exposed to different photoperiods Crescimento e sobrevivência do tambaqui exposto a diferentes fotoperíodos

Acta Amazonica, 2006
The use of different photoperiods (light) were investigated during tambaqui (Colossoma macropomum) juvenile growth under captivity. Light intensity tested was: continuous dark (24hrs without light), natural photoperiod simulation (10hrs of light and 14hrs without light) and continuous light (24 with light).

Effects of trichlorfon on ecotoxicological biomarkers in farmed Colossoma macropomum (tambaqui)

Brazilian Journal of Biology
Abstract Producers of fish have been looking for viable alternatives for the management of Colossoma macropomum (tambaqui) in confinement systems in order to avoid the harm and subsequent losses caused by parasitic diseases. One alternative used by farmers is pesticides, such as trichlorfon, which has a genotoxic effect.

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 ...

Genetic diversity of tambaqui broodstocks in stock enhancement programs

Semina: Ciências Agrárias, 2017
Natural populations of tambaqui (Colossoma macropomum) have significantly decreased in recent decades especially due to human extraction activities. So that the environmental impact may be reduced, the restocking of fish and increase in fish production are enhanced. Genetic evaluations using molecular markers are essential for this purpose.
