Histamine in Brazilian Foods: A Comprehensive Review of Occurrence and Risk Assessment for Intoxication and Intolerance

open access: yesFood Science &Nutrition, Volume 13, Issue 11, November 2025.
Even though histamine plays an important role in human health, it has been associated with food intoxication and intolerance episodes. The most relevant, current state of knowledge regarding histamine's biochemical and health aspects is provided. Histamine levels are provided for 17 food groups, including 335 food types and 11,437 samples, allowing ...

Genetic diversity and structure in populations of Piaractus mesopotamicus

open access: yesBrazilian Journal of Animal and Environmental Research
Inadequate genetic management of broodstock in fish farming can lead to a reduction in genetic diversity, negatively affecting key productive traits such as growth and weight gain. This study evaluated the genetic diversity and population structure of pacu (Piaractus mesopotamicus Holmberg, 1887) from two fish farms located in the states of Bahia and ...

Dietary Phosphorus Requirement for Tambaqui, Colossoma macropomum, in the Grow‐Out Phase

open access: yesJournal of Animal Physiology and Animal Nutrition, Volume 109, Issue 6, Page 1321-1332, November 2025.
ABSTRACT Phosphorus is essential for fish growth as it is crucial in skeletal development and metabolic reactions. The dietary requirement for this mineral varies among fish species and growth stages. Therefore, the objective of this study was to determine the available phosphorus (AP) requirement for tambaqui during the grow‐out phase (± 400 to 1000 g)

Modulation of stress and innate immune response by corticosteroids in pacu (Piaractus mesopotamicus)

open access: yesComparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2019
Understanding how stress and corticosteroid modulates the innate immune response is one of the keys to improving productivity and reducing losses in intensive aquaculture. Thus, we investigated the effects of dietary corticosteroids (7 days; long-term exposure) and transport (4 h; short-term stress) on stress and innate immune response in pacu.
