Lower light intensity reduces larval aggression in matrinxã, Brycon amazonicus

Behavioural Processes, 2018
Brycon amazonicus shows a high frequency of aggressive behavior, which can be a limiting factor in intensive farming systems. Environmental changes can modulate the social interactions of fish and reduce aggression during the different stages of production.

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).

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.
