Impacts of stocking on the genetic diversity of Colossoma macropomum in central Amazon, Brazil

Genetics and Molecular Research, 2016
Tambaqui (Colossoma macropomum) is the main fish species farmed on a commercial scale in northern Brazil. In view of the current scenario of Brazilian aquaculture, studies on the genetic improvement and reproductive management of captive tambaqui are crucial in identifying the genetic variability of broodstocks and devising management practices ...

Impacts of Global Warming on Quality of Male Fishes: Evidence From A Meta‐Analysis of Temperature Effects on Sperm Motility Kinematics

Reviews in Aquaculture, Volume 17, Issue 1, January 2025.
ABSTRACT Studies have demonstrated adverse effects of global warming on aquatic ecosystems. However, the effects of increased water temperature (IWT) on fish reproduction are still doubtful in species spawning at low or high temperatures. In this meta‐analysis, we elucidated the effects of global warming on spermatozoa functions, key determinants of ...

Dietary Herbal Leaves Mixture Extract Enhances Growth, Antioxidant Status, and Resistance to Gyrodactylus malalai in Heteroclarias Catfish, Clarias gariepinus ♀ × Heterobranchus longifilis ♂

Aquaculture Nutrition, Volume 2025, Issue 1, 2025.
Gyrodactylus malalai commonly attacks fish gills, which can swiftly infect entire fish stocks and cause both biological and monetary losses. The most popular treatment for G. malalai infestations in fish farms is chemotherapy; however, these drugs can have major side effects and are expensive. Novel and ecologically friendly treatments are necessary to

Extreme climate scenario and parasitism affect the Amazonian fish Colossoma macropomum

Science of The Total Environment, 2020
Global warming caused by greenhouse gases accumulation, in particular carbon dioxide, is the major current environmental challenge, as it will affect all life forms over the next decades. Aquaculture, a fast growing food production sector, is already facing the effects of global warming.

Effect of Biofloc Culture on the Daily Rhythmicity of the Activity and Expression of Digestive Enzymes in Tilapia, Oreochromis niloticus

Aquaculture Nutrition, Volume 2025, Issue 1, 2025.
Biofloc technology (BFT) has recently attracted great attention due to minimal water exchange and reduced feed intake. This study aimed to recognize daily changes in the digestive physiology of Oreochromis niloticus between a traditional system and BFT.

Technical aspects for cachama cultivation (Piaractus brachypomus & Colossoma macropomum)

, 2020
The white cachama (Piaractus brachypomus) and the black cachama (Colossoma macropomum), are species of fish belonging to the family of the Caracides. Both are native to the Amazon River and Orinoco basins, are part of river fishing and represent an abundant and desirable fishery product. In Venezuela, cachama has been cultivated since 1977 when induced

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.

Modelling growth of Colossoma macropomum (Cuvier): comparison of an empirical and an explanatory model

Aquaculture Research, 1998
Accumulated data from growth experiments on the nutrition of Colossoma macropomum (Cuvier) were analysed using an empirical (linear regression) and an explanatory model called the fish growth simulator (FGS). Both methods gave satisfactory results. Differences between predicted and observed values fluctuated less with the FGS.

Tambaqui (Colossoma macropomum) sous vide: characterization and quality parameters

Semina: Ciências Agrárias, 2016
The objective of this study was to evaluate the microbiological, physical and physico-chemical quality parameters of sous vide preparation of pen-reared tambaqui (Colossoma macropomum). To prepare the tambaqui sous vide, 200 g of fillet, 50 g of basil sauce (1:4 fish fillet:sauce ratio) and 10 mL of 5% sodium lactate were used.
