Social relationship as inducer of immunological and stress responses in matrinxã (Brycon amazonicus)

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2009
Matrinxã (Brycon amazonicus) is a freshwater neotropical fish species with a social interaction and aggressive behavior, especially in crowded environments. This species' social structure is established by agonistic interactions, which increase significantly at the fifth hour, when compared to the first and second hours of confinement, when each ...

Ultrastructure of the germ cells in the testis of matrinxã, Brycon cephalus (Teleostei, Characidae)

Tissue and Cell, 1999
This study describes at ultrastructural level the germ cells in the testis of matrinxã (Brycon cephalus) raised in captivity. The specimens 'matrinxã' were maintained in four breeding tanks of 200 m(2), at the Aquaculture Research Center at Vale do Ribeira-CEPAR, from Fishery Institute, in Pariquera-Açu City, São Paulo, Brazil.

Effects of phenol in antioxidant metabolism in matrinxã, Brycon amazonicus (Teleostei; Characidae)

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2008
Parameters of the antioxidant defense systems of Brycon amazonicus (matrinxã--a neotropical fish) exposed to phenol for 96 h plus the recovery over 1 and 2 weeks were studied in erythrocytes and liver. Hematocrit increase was observed during phenol exposure and recovery for 1 week.

Hematological responses of the Neotropical teleost matrinxã (Brycon cephalus) to environmental nitrite

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2004
Environmental increase in nitrite impairs the function of several aquatic species, including fishes. Nitrite reacts with hemoglobin yielding the non-functional methemoglobin (metHb), and many physiological disturbances can arise. The physiological mechanisms to cope with nitrite are still unclear in fish.
