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
