Salt as a stress response mitigator of matrinxã,Brycon cephalus(Günther), during transport
Aquaculture Research, 2001 The present study evaluated the physiological responses of matrinxa, Brycon cephalus (Gunther), submitted to transport stress under the influence of sodium chloride, Different salt concentrations (0.0%, 0.1%, 0.3% and 0.6%) were added to four 200-L ...

, 2016 Para avaliar o efeito da exposição de ovos de matrinxã à triiodotironina, sobre o desenvolvimento embrionário, ovócitos extrusados foram fertilizados e imersos em soluções de 0,00; 0,01; 0,05 e 0,10ppm de triiodotironina, durante a hidratação. A pesquisa foi desenvolvida no Centro Nacional de Pesquisa em Peixes Tropicais (CEPTA/IBAMA), Pirassununga, SP,

Transport Stress in Matrinxã, Brycon cephalus (Teleostei: Characidae), at Different Densities
Aquaculture International, 2002 Matrinxa, Brycon cephalus, is a nativeteleost fish from the Amazon Basin, and is of economic importance forcultivation for food and sport in Brazil. Mortality losses due to handling andtransport of this stenohaline freshwater species are common. The effects oftransportation at different densities on the biochemical stress responses ofmatrinxa (mean ...

Metabolic changes in Brycon cephalus (Teleostei, Characidae) during post-feeding and fasting
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2002 Metabolic changes during the transition from post-feeding to fasting were studied in Brycon cephalus, an omnivorous teleost from the Amazon Basin in Brazil. Body weight and somatic indices (liver and digestive tract), glycogen and glucose content in liver and muscle, as well as plasma glucose, free fatty acids (FFA), insulin and glucagon levels of B ...

Metabolic responses of matrinxã (Brycon cephalus) to dietary protein level
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2005Effects 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.

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.

Ultrastructure of the germ cells in the testis of matrinxã, Brycon cephalus (Teleostei, Characidae)
Tissue and Cell, 1999This 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.
