Benefits of Virgin Coconut Oil in Diet to Colossoma macropomum (Cuvier, 1818). [PDF]
This study investigated the effects of different dietary levels of virgin coconut oil on growth, body composition, bacterial resistance, and hematology parameters in tambaqui (Colossoma macropomum). Six isolipidic (12% crude lipid) and isonitrogenous (33% CP) diets were formulated adding virgin coconut oil (0%, 25%, 50%, 75%, and 100%) as lipid source,

Morphographic Changes in the Electrocardiogram of Colossoma macropomum Caused by Exposure to Manganese. [PDF]
Manganese (Mn2+) is an abundant chemical element in the earth’s crust and is present in soil, water, and industrial environments, including mining, welding, and battery manufacturing. Manganese (Mn) is an essential metal needed as a cofactor for many enzymes to maintain proper biological functions. Excessive exposure to Mn in high doses can result in a

Nitrogen budget and fluxes in Colossoma macropomum ponds [PDF]
This study quantified the accumulation of nitrogen (N) in the water column, sediments, fish and seepage water during a production cycle of Colossoma macropomum. By combining estimates of the deposition rates of uneaten feed, faeces and dead phytoplankton with measurements of N accumulation in the sediment, the rate of decomposition of organic matter in

Digestible tryptophan requirement for tambaqui (Colossoma macropomum) fingerlings
ABSTRACT The objective of this study was to determine the digestible tryptophan requirement of tambaqui (Colossoma macropomum) fingerlings and its relationship with digestible lysine. A total of 300 tambaqui fingerlings with three initial weights (2.12 ± 1.19, 8.13 ± 0.75, and 15.18 ± 1.91 g) were distributed in a randomized complete block design ...

Innovative molecular approach to the identification of Colossoma macropomum and its hybrids [PDF]
Tambaqui (Colossoma macropomum) is the fish species most commonly raised in the Brazilian fish farms. The species is highly adaptable to captive conditions, and is both fast-growing and relatively fecund. In recent years, artificial breeding has produced hybrids with Characiform species, known as "Tambacu" and "Tambatinga".
