“…These populations are fully maintained by reintroductions from hatchery stocks after hydroelectric schemes destroyed their primary spawning grounds. Initial studies revealed that socially acquired avoidance of predator odours is particularly effective means of training naïve fishes to recognise predators (Vilhunen et al 2005) and these early exposures to predators do lead to improved survival upon subsequent contact with live predators (Vilhunen 2006). …”

“…This study did not address the recognition of predators by chemical cues, and thus it cannot be ruled out that juveniles recognize piscivores by olfaction. Juvenile fish that are not born with the ability to recognize their predators may acquire or refine that ability by 1 or more of 3 processes: (1) maturation of the sensory or neural system, which does not require exposure to a predator (Munz & McFarland 1973, Coss 1978, Blaxter 1986; (2) individual learning, which may be a dangerous process that involves the exposure of a naive fish to a predator (Csanyi & Doka 1993); and (3) social transmission, by which a naïve fish may learn to recognize predators through exposure to them in company with experienced individuals (Mathis et al 1996, Vilhunen et al 2004. Several recent studies have addressed the problem of social transmission of predator recognition with relation to stock rehabilitation programs and sea ranching of commercial edible fishes (reviewed by Suboski & Templeton 1989, Brown & Laland 2001, but none in connection with reef fishes.…”

Predator recognition was studied in Dascyllus marginatus, a small Red Sea pomacentrid that forms mixed-size schools associated with branching corals of the genera Acropora and Stylophora. The reactions of variously sized D. marginatus to sudden exposure to a live predatory fish (Epinephelus fasciatus), a non-predatory fish (Acanthurus nigrofuscus), and an empty cell were monitored in the laboratory. Adult fish (49 to 60 mm) discriminated between predatory and non-predatory fish, whereas juveniles (13 to 17 mm) could not. The responses of single juveniles, pairs of juveniles, and juvenile/adult pairs to sudden exposure to a predator were compared. Juveniles paired with adults avoided the predator more than single or paired juveniles. A mechanism in the reef habitat of social facilitation of predator recognition and avoidance among mixed-sized school pomacentrids is suggested. The relevance of the findings of this study to the low survival of reef fishes shortly after settlement and their preference for coral heads inhabited by conspecifics is discussed.

“…Brown and Laland (2001) suggested that the manipulation of social learning in captivity might improve the viability of hatchery-raised fish in the wild, thus enhancing the population in the wild. An experimental study by Vilhunen, Hirvonen, and Laakkonen (2004) showed the efficacy of social learning as a way to improve antipredator behavior in Saimaa Arctic char (Salvelinus alpinus). In contrast to expectations from theory, the naive fish learned better with a relatively small proportion of experienced fish.…”

Conserving and managing animals that learn socially and share cultures

Socially learned behavior can be a crucial factor in how animals interact with their environment and, thus, in conservation and management. For species in which social learning and culture are important determinants of behavior, several factors complicate conservation and management. These include the rapid spread of novel behavior through social learning, the inhibition of adaptive behavior because of cultural conformism, the evolution of maladaptive behavior, and the development of culturally isolated but sometimes sympatric groups. These factors can affect habitat suitability, movements, how animals react to anthropogenic effects, and genetic structures. Social learning and culture may be important factors in translocation success, and should sometimes be considered when delineating population units for conservation and management. We should aim to protect cultural as well as genetic diversity. Unfortunately, clear data on social learning and culture in the wild are scarce. Hence, the ideas and methods outlined in this special issue have great potential.
