Cryopreservation of yamú (Brycon amazonicus) sperm for large scale fertilization

Aquaculture, 2006
Abstract To determine the effect of straw size and thawing temperature on cryopreserved sperm quality of yamu ( Brycon amazonicus ), ovulation and spermiation were induced in sexually mature broodstock using Carp Pituitary Extract. Sperm quality was evaluated by motility, activation time and fertility. Sperm was diluted (1:4) in a solution of glucose,

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.

Dietary l-tryptophan alters aggression in juvenile matrinxã Brycon amazonicus

Fish Physiology and Biochemistry, 2011
This study evaluated the effect of dietary supplementation with L: -tryptophan (L-TRP), a serotonin precursor, on the aggressiveness of juvenile matrinxã Brycon amazonicus. Fish were kept in individual aquaria for 7 days receiving the diets: D1 (control: 0.47% of TRP), D2 (0.94% of TRP), D3 (1.88% of TRP), and D4 (3.76% of TRP).

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 ...

Cadmium-induced disruption of environmental exploration and chemical communication in matrinxã, Brycon amazonicus

Aquatic Toxicology, 2008
The effects of cadmium exposure on both environment exploration and behavioral responses induced by alarm substance in matrinxã (Brycon amazonicus), a fish species endemic to the Amazon basin, were investigated. Fish exposed to 9.04+/-0.07 microg/L waterborne cadmium for 96h followed by 24h depuration period in clean water, were video-recorded for 15 ...

Assessment of biomarkers in the neotropical fish Brycon amazonicus exposed to cypermethrin-based insecticide

Ecotoxicology, 2018
The effects of cypermethrin-based insecticide (CBI), commonly used in aquaculture and agriculture, were evaluated in matrinxa (Brycon amazonicus) exposed to sub-lethal concentration (20% of LC50) for 96 h. Physiological and biochemical effects were studied through biomarkers: lipid peroxidation (LPO), glutathione (GSH), and ascorbic acid concentrations;
