Loading and transport stress of juvenile matrinxã (Brycon cephalus, Characidae) at various densities

Aquaculture, 2004
Abstract Physiological responses of matrinxa juveniles were determined after the procedures of capture, loading and 4-h transportation at densities of 83, 125 and 166 g l −1 . The experiment was carried out during the regular procedures of the local hatcheries, repeating the real conditions of transportation.

Effects of dietary aflatoxin on biochemical parameters and histopathology of liver in Matrinxã (Brycon cephalus) and Pacu (Piaractus mesopotamicus) fish

World Mycotoxin Journal, 2021
The objective of this study was to evaluate biochemical parameters and histopathology of liver in Matrinxã (Brycon cephalus) and Pacu (Piaractus mesopotamicus) fish chronically exposed to dietary aflatoxins.

Metabolic responses of matrinxã (Brycon cephalus) to dietary protein level

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2005
Effects of increasing dietary protein were studied in matrinxa, (Brycon cephalus), an omnivorous teleost from the Amazon Basin in Brazil. Four isocaloric diets were formulated to contain 20%, 27%, 34% and 41% of crude protein (CP). Plasma glucose levels were significantly increased while triacylglycerols were significantly reduced at 41% of CP.

Light and electron microscopy oogenesis in matrinxã, Brycon cephalus.

Journal of submicroscopic cytology and pathology, 2003
Oocyte development has been divided into 5 distinct stages in the reared matrinxã, Brycon cephalus, based on morphological criteria by light and transmission electron microscopy: I) chromatin-nucleolus; II) perinucleolar; III) cortical alveoli; IV) vitellogenesis; V) final maturation.

Metabolic responses to glucoprivation induced by 2-deoxy-D-glucose in Brycon cephalus (Teleostei, Characidae)

Journal of Comparative Physiology B: Biochemical, Systemic, and Environmental Physiology, 2004
The effects of functional cytoglucopenia provoked by 2-deoxy-D-glucose (2-DG) were studied in adult Brycon cephalus, an omnivorous fish from the Amazon Basin in Brazil. Glycogen content in liver and muscle as well as plasmatic glucose, free fatty acids (FFA), insulin, and glucagon were measured.
