“…Hatchery-reared fishes stocked into natural waterways often suffer intense predation pressure (Shively et al 1996;Henderson & Letcher 2003), particularly within the first days to weeks post-stocking. However, to date, such an approach has met with limited success (Wisenden et al 2004;Hawkins et al 2007). For example, Hawkins et al (2007) conditioned hatchery-reared juvenile Atlantic salmon to recognise pike and released conditioned and unconditioned salmon into a loch in which pike was the major predator of juvenile salmon.…”

“…The effect is observed here in tadpoles derived from exposure to conspecific-fed crayfish. A similar learning process, known as "releaser-induced recognition learning", has been well described in fish, where it is now recognized that chemicals released by injured conspecifics play a major role in the acquired chemical recognition of an unfamiliar predator (Mathis & Smith 1993;Chivers & Smith 1994a, b;Brown & Smith 1998;Wisenden 2000;Korpi & Wisenden 2001;Wisenden et al 2004;Darwish et al 2005;Larson & McCormick 2005). Recent observations on common toad tadpoles (Mandrillon & Saglio 2005) and adults of the central newt Notophthalmus viridescens (Woody and Mathis 1998) indicate that amphibians can similarly learn to recognize an unfamiliar odour as representing a predation risk based on a prior association between this odour and the chemical cues from experimentally crushed conspecifics.…”

“…In this connection, a growing body of evidence suggests that 32 A.-L. Mandrillon and P. Saglio CHEMOECOLOGY aquatic invertebrates and vertebrates have the ability to learn to recognize the chemical cues released by unfamiliar predators. Such a chemical conditioning appears to be based on an association between the odour per se of the predator and the presence of alarm substances from preyed conspecifics (Mathis & Smith 1993;Chivers & Smith 1994a, b;Wisenden et al 1997;Brown & Smith 1998;Woody & Mathis 1998;Wisenden 2000;Korpi & Wisenden 2001;Wisenden & Millard 2001;Wisenden et al 2004;Darwish et al 2005;Ferrari et al 2005;Larson & McCormick 2005;Mandrillon & Saglio 2005). In the common toad (Bufo bufo), we recently found that tadpoles were able to establish a conditioning association between conspecific and predator chemicals.…”

In amphibians and fishes, evidence is increasing that chemical cues from injured conspecifics can play a role in the chemical labelling and learned recognition of unfamiliar predators. In this laboratory study, we tested the prediction that prior chemical exposure to a non-native predator feeding on conspecific tadpoles will subsequently allow tadpoles of the common toad (Bufo bufo) to recognize the chemical cues specifically released by this starved predator. Furthermore, we investigated the vulnerability of this chemically-mediated process to herbicide contamination. With these aims in view, groups of tadpoles were kept either unexposed or exposed for ten days to chemical cues from Turkish crayfish (Astacus leptodactylus) previously fed on tadpoles, both in uncontaminated water and in the presence of four sublethal concentrations of amitrole (0.01, 0.1, 1 and 10 mg.l -1 ). We then assessed the effects of the six conditioning treatments on general activity and behavioural response to chemical cues from starved crayfish. Larval treatments did not affect the general activity of the tadpoles. By contrast, the treatments had significant effects on the behavioural response to the test solution prepared form starved crayfish. The only tadpoles to show an antipredator behavioural response to the chemical stimulation from starved crayfish belonged to the groups derived from chemical exposure to tadpole-fed crayfish in uncontaminated water and in contaminated water with the lowest concentration of amitrole (0.01 mg.l -1 ). Conversely, this chemical stimulation produced no behavioural change in the control group or in the groups derived from exposure to tadpole-fed crayfish in contaminated water containing 0.1, 1 and 10 mg.l -1 of amitrole. This study demonstrates that chemical cues released during the predator's feeding activity can subsequently be used by common toad tadpoles in the recognition of an unfamiliar predator. In addition, our results show that the presence of sublethal amitrole concentrations can impair this recognition process. Such a pesticide effect might be especially detrimental for amphibian populations threatened by invasive predators.

“…But club cells are not unique only among the Ostariophysi. Fishes in the Percidae (Acanthopterygii) also possess club cells with similar histological properties as club cells in the Ostariophysi (see Smith 1992, Wisenden et al 2004, Chivers et al 2007.…”

Päkk P., Hussar P., Paaver T. 2011. Alterations of club cell activity in epidermis of common carp, Cyprinus carpio (Actinopterygii: Cypriniformes: Cyprinidae), due to infection by Ichthyophthirius multifiliis (Protista: Ciliophora). Acta Ichthyol. Piscat. 41 (3): 185-192.Background. The abundance of club cells in epidermal tissue of fishes in the superorder Ostariophysi is a poorly understood phenomenon. Previous results have suggested that epidermal club cells have a generic role in response to injury and that they display intense phagocytotic activity, having an anti-parasitic function in the host. Earlier works suggested that club cells are usually located in the middle of the epidermis and that they do not communicate with the epidermal surface or do it only when the epidermis has been ruptured by predation. The presently reported study focused on the alterations of club cell activity in carp epidermis induced by ectoparasite, Ichthyophthirius multifiliis. We hoped that our observations would help to understand the function(s) of these cells. Materials and methods. This study was based on 200 four-month old common carp, Cyprinus carpio L., with mean body weight of 65 ± 5 g. The fish were experimentally infected with theronts of Ichthyophthirius multifiliis. In sequential days post infection, samples of fins and body skin were collected for histological and histochemical examination. The correlation between club cell densities and mucous cell densities was analysed using Pearson correlation analyses. Results. A local reduction of mucous cells occurred after theront invasion-induced proliferation, and increased club cell density around the parasite during the growth of trophonts. After parasites left the skin due to salt-water treatment, a decrease in the number of club cells was detected. During reinvasion the decrease in parasite activity in areas of club cells proliferation was not noted. It was found that giant mature club cells were opened on the surface. Conclusion. Club cells have no anti-parasitic function against I. multifiliis and these mature cells released their viscous secretion into water. The high density of club cells in the epidermis compensates an overall low density or absence of mucous cells. As it can be hardly concluded that the function of club cells is phagocytic removal of cell debris, an integrated research on mucosal immune mechanisms, as well as studies on epidermal tissue responses on product(s) released by club cells ("alarm substance cells") should be carried out in the future.
