“…The analysis of the distance covered by A. hippolytae females to attack intruders suggests that females have the ability to perceive potential predators and variable levels of risk to their offspring, as previously observed for African (Ochi and Yanagisawa 1998) and Neotropical cichlids (Barreto et al 2003). Moreover, the high frequency of intraspecific attacks may be related to the high abundance and aggregated distribution of A. hippolytae in the pond (based on our personal observations).…”

Reproductive behavior of the Amazonian dwarf cichlid Apistogramma hippolytae Kullander, 1982: offsetting costs and benefits

The reproduction trade-off for an animal is a conflicting choice in which resources (e.g., time and/or energy) allocated to one reproduction trait (e.g., parental care) become unavailable to other traits (e.g., future reproduction events). Here, we tested three hypotheses related to the parental care of the Amazonian dwarf cichlid Apistogramma hippolytae in its natural habitat of Central Amazonia: (1) brood-caring females have a lower feeding frequency than individuals that are not involved in this behavior; (2) females that spend more time on nest defense have lower feeding rates; and (3) females can recognize the species that present the greatest danger to its offspring and move farther from the nest to chase away these piscivorous fishes. We also described for the first time the reproductive behavior (including courtship) and parental care of this species. The results showed that maternal care produces a reduction in the rate of feeding of mothers, a greater amount of time is spent chasing invaders away from the nest, and reproductive females are able to distinguish species-specific predators. These observations support the hypotheses of this study and also suggest a trade-off between current and future reproduction events.

“…Likewise, Hawkins et al (2004) have shown that juvenile Atlantic salmon (S. salar, Salmonidae) significantly increased opercular flap rates upon detection of novel cues, suggesting increased vigilance or olfactory sampling as opposed to true recognition (Gibson & Mathis 2006). Predator naive Nile tilapia (Oreochromis niloticus, Cichlidae) show a similar increase in opercular movements during exposure to visual predator cues (Barreto et al 2003).…”

“…In addition, the absence of stress does not necessarily indicate good welfare conditions. From an evolutionary standpoint, it is reasonable to suppose that natural selection has conditioned animals to have stereotyped responses to risky situations, as occurs when they are subjected to stressful conditions, such as innate predator recognition (Jordao and Volpato 2000;Barreto et al 2003;Hawkins et al 2007;Freitas and Volpato 2008). In contrast, it is hard to conceive the selection of standardised physiological responses to situations that provide welfare conditions.…”

The mission of defining animal welfare indicators is methodologically difficult, limited, and possibly impossible. A promising alternative, however, to evaluate suitable environmental conditions is the assessment of play behaviour. In the present review, we summarise the general aspects of play behaviour in nonhuman animals and propose its use as a potential indicator of animal welfare. Play behaviour probably occurs in most vertebrates and some invertebrates, but predominately in mammals. It is also more frequent in young males and is associated with the environmental context in which animals find themselves. Animals play if they are healthy and well-fed, but not if they are under stressful conditions or if they are in a stressful state. We can therefore use the prevalence of play behaviour as an indicator of suitable environmental conditions, considering the specificity associated with the above-mentioned modifying factors.
