Abstract

Motile Aeromonas septicemia (MAS) is a common bacterial fish disease that may cause severe economic losses. This novel study was conducted to investigate behavioral changes of Nile tilapia (Oreochromis niloticus) in response to experimental induction of MAS. Aeromonas hydrophila, which is the...

Abstract

In species with indeterminate growth, differential growth rates can lead to animals adopting alternative reproductive tactics such as sneak-guard phenotypes, which is partially predicted by variation in growth during the juvenile life-history stage. To investigate sources of growth variation, we...

Abstract

Chronic stress may cause physical, behavioral and neuropsychiatric changes, affecting the health condition of an individual. Aggression is a universal behavior with great relevance on human and animal social systems. Despite studies showing the influence of chronic stress on aggression, the effects ...

AbstractFull Text

The response of cultured rainbow trout to their mirrored image was investigated. Thirty fish were placed individually in two novel aquariums consecutively for 10 min each. Walls in one aquarium were covered with mirrors on all four sides, whereas the walls of the other aquarium were non-transparent ...

Abstract

The neural circuitry for social behavior and aggression appears to be evolutionarily conserved across the vertebrate subphylum and involves a complex neural network that includes the hypothalamus as a key structure. In the present study, we evaluated the changes in monoamine levels in the...

Abstract

The primary goal of this study was to understand how changes in temperature and oxygen could influence social behaviour and aerobic metabolism of the Amazonian dwarf cichlid Apistogramma agassizii. Social hierarchies were established over a period of 96 h by observing the social interactions,...

Abstract

Behavioural observations of juvenile Diplodus sargus in natural habitats were conducted to test whether agonistic interactions occur in natural circumstances and, if they do, in which context they happen. The level of aggression and the shoals composition were also compared between distinct natural ...

Abstract

In natural spawning grounds, breeding round goby, Neogobius melanostomus, males are exposed to various social stimuli, including high density of same-sex competitors and separation from females. We hypothesize that breeding males subjected to overcrowding in the wild experience high stress that...

Abstract

Studies of contest competition between wild and farmed fish have mostly focused on fish with strongly territorial behaviour. Little is known about species with more plastic social behaviour, such as Atlantic cod (Gadus morhua L.), a species that can either aggressively defend territories or shoal....

Abstract

Salmonids are characterized by alternative reproductive tactics, which can lead to an asymmetry in relatedness among offspring within nests and consequently the benefit of discriminating among nestmates. In this study, we examined the effect of paternal reproductive tactic on juvenile behaviour and ...
