“…Before each replicate, an average sized 0+ perch was introduced to the predator for the production of predator-induced chemical alarm signal (Mathis et al 1995;Mirza et al 2003;Harvey and Brown 2004). After the change of the experimental set-up concerning the predator, everything was cleaned and the whole water was replaced to diminish long lasting effects of chemical cues.…”

The 0+ cohort of perch can split into a slow-growing planktivorous and a fast-growing piscivorous cohort during their first months of life. Both cohorts are, however, vulnerable to predation by piscivorous fish. Laboratory experiments were performed to test the behavior of 0+ perch as a predator of cyprinids, and in the tradeoff between food and shelter from the threat of predators. In the foraging trials, 0+ perch attacked bream faster than they did carp, and vegetation hampered the aggression against bream. In the second experiment, the habitat selection of two size classes of 0+ perch under the threat of predation was monitored. Overall, vegetation structures were preferred by both size classes of 0+ perch. When small fish were offered to the 0+ perch as food, the open water becomes more attractive. The results of the habitat use trials further show that the two size cohorts of 0+ perch may also differ in their behavior, in that the availability of fish as food becomes more important than the shelter of vegetation structures for the larger perch.

“…All juveniles had the same size range, but those from the experiments with Megaleporinus were descendants from a different pair than those from the other experiments. Variations in the response of water controls was also observed in yellow perch (Perca flavescens) Harvey, Brown (2004).…”

“…However, when adult silver catfish were exposed to conspecifics alarm cues they remained immobile in the first minutes and then increased swimming activity (Souza-Bastos et al, 2014), as observed in the present study. Furthermore, Rivulus hartii (currently Anablepsoides hartii) and yellow perch also demonstrated significant size-dependent trends in response to heterospecific and conspecific alarm cues, respectively, with smaller individuals exhibiting antipredator responses and larger individuals shifting their behavior to increased levels of activity consistent with a foraging or predatory response (Harvey, Brown, 2004;Elvidge et al, 2010).…”

The recognition of chemical information indicating the presence of a predator is very important for prey survival. In this study we tested antipredator behavioral response of juvenile silver catfish (Rhamdia quelen) against predator odor released by two different potential predators, Hoplias malabaricus and the snake Helicops infrataeniatus, and alarm cues and disturbance cues released by conspecifics and by non-predator species, Megaleporinus obtusidens and Astyanax lacustris. We used juvenile catfish that were naive to predators. The trials consisted of a 10-min prestimulus and a 10-min post-stimulus observation period. The behavioral response displayed by silver catfish exposed to alarm cues comprised a decrease in shelter use and an increase in locomotion, and also a longer latency period before feeding. Our results showed that juvenile silver catfish can perceive chemical cues released by predators, heterospecifics and conspecifics.Keywords: Alarm cues, Anti-predator behavior, Disturbance cues, Predator odor, Skin extract.O reconhecimento das informações químicas indicando a presença de predadores é muito importante para a sobrevivência da presa. Neste estudo foi testada a resposta comportamental anti-predação de juvenis de jundiás (Rhamdia quelen) a substâncias liberadas por dois predadores potenciais, Hoplias malabaricus e a cobra Helicops infrataeniatus, e substâncias de alarme liberadas por conspecíficos e pelas espécies não predadoras Megaleporinus obtusidens e Astyanax lacustris. Foram usados juvenis de jundiá que não possuíam nenhum contato prévio com predadores. Os testes consistiram em observações de períodos de 10 minutos pré estímulo e 10 minutos pós estímulo. As respostas comportamentais apresentadas pelos jundiás expostos às substâncias de alarme consistiram em diminuição no uso do abrigo, aumento na locomoção e também um longo período de latência antes de ingerir o alimento. Os resultados demonstram que juvenis de jundiá percebem substâncias químicas liberadas por predadores, heterospecíficos e conspecíficos.

“…Increased local recruitment of predators in the presence of damage-released prey cues under natural conditions (Elvidge & Brown, 2012;Wisenden & Thiel, 2002) and increased predator foraging behaviour under laboratory conditions provide additional evidence for the occurrence of exploitative use of chemicals in this context. Conversely, size and life-history mediated differences in response to damage-released cues Harvey & Brown, 2004; this study) may not be indicative of foraging responses to damage-released cues, but rather decreased relevance of a particular cue to larger receivers (Brown, Ferrari, et al, 2010) that have grown out of the size range susceptible to shared common predators (Popova, 1978).…”
