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 ...

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 ...

Loading and transport stress of juvenile matrinxã (Brycon cephalus, Characidae) at various densities

Aquaculture, 2004
Abstract Physiological responses of matrinxa juveniles were determined after the procedures of capture, loading and 4-h transportation at densities of 83, 125 and 166 g l −1 . The experiment was carried out during the regular procedures of the local hatcheries, repeating the real conditions of transportation.

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.

Light and electron microscopy oogenesis in matrinxã, Brycon cephalus.

Journal of submicroscopic cytology and pathology, 2003
Oocyte development has been divided into 5 distinct stages in the reared matrinxã, Brycon cephalus, based on morphological criteria by light and transmission electron microscopy: I) chromatin-nucleolus; II) perinucleolar; III) cortical alveoli; IV) vitellogenesis; V) final maturation.

Metabolic responses to glucoprivation induced by 2-deoxy-D-glucose in Brycon cephalus (Teleostei, Characidae)

Journal of Comparative Physiology B: Biochemical, Systemic, and Environmental Physiology, 2004
The effects of functional cytoglucopenia provoked by 2-deoxy-D-glucose (2-DG) were studied in adult Brycon cephalus, an omnivorous fish from the Amazon Basin in Brazil. Glycogen content in liver and muscle as well as plasmatic glucose, free fatty acids (FFA), insulin, and glucagon were measured.

The role of olfaction in the behavioural and physiological responses to conspecific skin extract in Brycon cephalus

Journal of Fish Biology, 2003
A behavioural alarm reaction was shown by 78% of the non‐operated juvenile matrinxãBrycon cephalus exposed to a conspecific skin extract, whereas the other 22% did not change their behaviour. The main reaction (72% of those reacting) consisted of a brief initial phase (2 min) of dashing or very rapid swimming followed by a long‐lasting period of ...

Hormonal induction ofBrycon 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
