Hunger suppresses the onset and the freezing component of the antipredator response to conspecific skin extract in pintado catfish
(Brill Academic Publishers, 2001-10-01)
Although the skin of an injured conspecific releases alarm substance in some fish species, it has been shown that such damage induces feeding behaviour rather than an alarm reaction under conditions of food scarcity. We ...

Fish Aversion and Attraction to Selected Agrichemicals
(2016-10-01)
In agriculture intensive areas, fishponds and natural water bodies located in close proximity to these fields receive water with variable amounts of agrichemicals. Consequently, toxic compounds reach nontarget organisms. ...

Impacto de pesqueiros e avaliação do potencial invasor de espécies de peixes do trecho paulista da Bacia Hidrográfica do Rio Paraíba do Sul
(Universidade Federal de São Paulo, 2023-07-10)
A introdução de espécies não nativas é uma grande preocupação ambiental. Muitos impactos negativos são causados por espécies invasoras e essa problemática é considerada como uma das principais causas de perda de biodiversidade ...
Blood Cues Induce Antipredator Behavior in Nile Tilapia Conspecifics
(2013-01-18)
In this study, we show that the fish Nile tilapia displays an antipredator response to chemical cues present in the blood of conspecifics. This is the first report of alarm response induced by blood-borne chemical cues in ...
First record of Lernaea cyprinacea (Copepoda) in a native fish species from a Brazilian river
(2013)
This is the report of the occurrence of Lernaea cyprinacea (Linnaeus, 1758) parasitizing the native fish species Steindachnerina insculpta (Fernández-Yépez, 1948). Sixty host specimens were captured in Taquari River, ...
Ventilatory frequency indicates visual recognition of an allopatric predator in naive Nile tilapia
(Elsevier B.V., 2003-01-31)
Perceiving a possible predator may promote physiological changes to support prey 'fight or flight'. In this case, an increase in ventilatory frequency (VF) may be expected, because this is a way to improve oxygen uptake ...
