“…Nevertheless, hatchery‐reared fish displayed a significantly lower night‐time activity, while wild fish did not. The more intense nocturnal movement of wild fish may be connected with feeding and predator avoidance (Vanderpham et al , ); this difference has been noted for related species, such as for S . trutta (Diana et al , ) and Atlantic salmon Salmo salar L. 1758 (Fraser et al , ).…”

Juvenile wild and hatchery-reared European grayling Thymallus thymallus were tagged with radio-transmitters and tracked in the Blanice River, River Elbe catchment, Czech Republic, to study their behavioural response to stocking and environmental variation. Both wild and hatchery-reared T. thymallus increased their diel movements and home range with increasing light intensity, flow, temperature and turbidity, but the characteristics of their responses differed. Environmental variables influenced the movement of wild T. thymallus up to a specific threshold, whereas no such threshold was observed in hatchery-reared T. thymallus. Hatchery-reared fish displayed greater total migration distance over the study period (total migration) than did wild fish, which was caused mainly by their dispersal in the downstream direction.

“…For example, the response of bullies to predators has been studied using water scented with shortfin eel Anguilla australis (i.e., a native predator; Hammond‐Tooke, Nakagawa, & Poulin, ) and perch Perca fluviatilis (i.e., an introduced predator; Vanderpham, Nakagawa, & Clossy, ). Vanderpham et al () showed that G. cotidianus utilized shelter (i.e., PVC tubes) more in the dark when a predator odour was present compared to the control, but contrary to their predictions there was no difference between control and odour treatments in light conditions. The authors proposed that perhaps the lack of visual cues in addition to predator odour produced the unexpected results.…”

Parasites manipulating their host to facilitate trophic transmission is a widespread and diverse phenomenon. Trematode eye‐flukes in the family Diplostomidae infect a variety of fish species as metacercariae, many residing in the eyes. A recently described diplostomid, Tylodelphys darbyi, from the South Island of New Zealand has been found to infect common bully Gobiomorphus cotidianus, an endemic freshwater fish. Within the fish, the metacercariae move about freely in the liquid parts of the eye and are quite large. We hypothesized that increasing intensity of T. darbyi infection will result in increasing visual impairment, thus reducing the ability of G. cotidianus to identify and react to a predatory threat. To test this hypothesis, we performed experiments to (a) examine the fish's reaction to a purely visual predator cue and (b) test their ability to avoid simulated predation under natural levels of infection. Among the 64 fish used in our experiments, T. darbyi had a prevalence of 98.7% with an average of 17.6 worms per fish. However, there was no relationship between T. darbyi intensity and either the fish's reaction to a visual predator stimulus or their ability to escape a simulated predator. Our findings indicate that despite being present in large numbers in the eyes of its fish host, the parasite appears incapable of improving its chances of trophic transmission to its avian definitive host. The results also suggest that the fish G. cotidianus could be using other senses (e.g., olfaction and lateral line) to compensate for visual impairment, and detect and respond to predators.

Species termed ‘habitat‐generalists’ are able to survive across a wide range of habitats, potentially enabled by the plastic behaviours and morphologies of individuals. This study aimed to compare habitat‐related adaptive specialisation in habitat‐generalists and specialists, by comparing feeding abilities of fish under varied hydrodynamic conditions. We compared the proportion of prey consumed by a New Zealand fluvial habitat‐specialist, the redfin bully, to a closely related habitat‐generalist found in fluvial and lacustrine habitats, the common bully, over a 6‐h period in either still or turbulent aquaria. We tested for intraspecific habitat‐specific adaptations by comparing feeding of common bullies from habitats with different hydrodynamic conditions. Within common bullies, previous research has documented a pattern of more lateral‐line system oculoscapular canal pores in fluvial habitats compared to lacustrine ones. By testing for a relationship between total pores and feeding success, we also aimed to identify the adaptive value of an increase in pores in turbulence. We identified decreased feeding (i.e., proportion of prey consumed) by both species in turbulence, but less so for redfin bullies. There was no clear indication of adaptation to habitat type by common bullies, with high variability in feeding by fish from all locations. We also found no statistical relationship between feeding and total oculoscapular canal pores. The results of this study suggest specialised adaptations of a habitat‐specialist to turbulent environments. The variability in feeding activity of common bullies also suggests the importance of behavioural plasticity in the survival of a habitat‐generalist across a wide range of conditions.
