Transport stress in matrinxã, Brycon cephalus (Teleostei: Characidae), at different densities

Aquaculture International, 2004
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 ...

Metabolical effects of Folidol 600 on the neotropical freshwater fish matrinxã, Brycon cephalus.

Environmental Research, 2004
The neotropical freshwater fish matrinxã, Brycon cephalus (Günther, 1869), was exposed to 1/3 of 96 h-LC50 of Folidol 600 (methyl parathion) for 96 h and allowed to recover for 24, 48, 96, and 192 h. Acetylcholinesterase (AChE), alanine aminotransferase (ALAT), aspartate aminotransferase (AAT), lactate dehydrogenase (LDH), malate dehydrogenase (MDH ...

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 ...

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.

Metabolical changes induced by chronic phenol exposure in matrinxã Brycon cephalus (teleostei: characidae) juveniles.

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2006
Phenol and its derivatives are xenobiotics present in many industrial wastewaters and in non-specific pesticides. It is a lipophilic compound and, therefore, accumulates along the trophic chain. Phenol is often found in marine and fresh water environments.

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.

Hormonal induction of Brycon cephalus (Characiformes, Characidae) to spermiation using D-ala6, pro9net-mGnRH + metoclopramide

Zygote, 2015
SummaryThis study aimed to establish a hormonal induction protocol for spermiation ofBrycon cephalusmales, using Ala6, Pro9Net-mGnRH + metoclopramide (Ovopel®). Thus, 20 males were used divided into three inductor treatments [⅓ pellet/kg (T1), ⅔ pellet/kg (T2) and 1⅓ pellet/kg (T3)] and one control group (CO), which only received physiological solution
