“…For example, Vainikka et al (2012a) found significant negative catch order effects on size variables in some perch populations, potentially arising from size-dependent dominance in feeding hierarchy (see also Tsuboi and Morita 2004). Kekäläinen et al (2014) conducted a study similar to ours, except that they focused only on a single population and used only the artificial or natural ice fishing gear at each fishing location.…”

“…On the other hand, long-term behaviour in a familiar environment may reflect an individual's intrinsic and state-dependent qualities, e.g. body condition or the motivation to feed, rather than personality (Tsuboi and Morita 2004;Philipp et al 2009). Due to assumedly highest food density in the risky sections (see Fig.…”

“…In particular, selective harvesting of certain behavioural types has been predicted to impose fishing-induced selection on fish personality (Lewin et al 2006;Uusi-Heikkilä et al 2008;Conrad et al 2011). According to current knowledge, individual fish differ in their vulnerability to angling (Tsuboi and Morita 2004), and recreational fishing can induce evolution of vulnerability to fishing, i.e. catchability ).…”

Behavioural variation in Eurasian perch populations with respect to relative catchability

Animal personalities, i.e. consistent individual differences in behaviour, are currently of high interest among behavioural and evolutionary biologists. The topic has received increasing attention also in fisheries science because selective harvesting of certain behavioural types might impose fishing-induced selection on personality. Here, we ice-fished wild Eurasian perch (Perca fluviatilis) from three native populations and investigated whether differences in relative catchability would explain behavioural differences observed in experimental conditions. We inferred relative catchability differences indirectly by fishing each location first with generally inefficient artificial bait and then by more efficient natural bait. The captured, individually tagged fish were tested in groups for their exploration tendency, activity and boldness under authentic predation risk in semi-natural stream channels. Fish that were easily captured first with artificial bait expressed fast exploration and acute activity, whereas the fish captured with natural bait showed less active and explorative behaviour. Differences in relative catchability did not explain variation in boldness or body size. In conclusion, we found that (1) Eurasian perch differing in relative catchability differ in certain behavioural traits, (2) fast explorers are more common among fish that get easily caught compared to fish that are more difficult to catch, (3) relative catchability explains more behavioural variation in a novel environment than in a familiar one and (4) selectivity of recreational angling on fish behaviour may depend on applied angling method and the effort spent on each location.

“…However, catchability of pike Esox lucius remained unaffected by previous captures with live baits [29]. Caught and released wild white-spotted charr (Salvelinus leucomaenis) were more likely to be caught than fish no caught before [30]. In their study on catch returns of European catfish, [31] demonstrated that some fish were more catchable than others, with some individuals caught numerous time and other never caught, suggesting that hook avoidance would not be a feature of that species.…”

Abstract:We filmed and analysed, in natural and field conditions, behaviours of large-bodied European catfish (Silurus glanis) individuals (body size ranging from 80 to 220 cm) exposed to a hook baited with 20 cm-long Carassius spp. Among a total of 95 individuals observed, 80 % of the catfish clearly demonstrated interest in the bait but attacks were performed only 25 % of the time and only 12.5 % of fish were hooked. More than half of the individuals (55 %) were observed swimming toward the bait and then turning around or tasting it without performing any attacks. These observations showed that individual fish motivation and behaviour are important factors in determining whether European catfish are attracted to bait and eventually hooked.

“…During fishing experiments with hook and lines and in catch-and-release fishing, lower catchability during the coarse of fishing has been observed in many species (Beukema & de Vos 1974;Hackney & Linkous 1978;O'Grady & Huges 1980;Yoneyama et al 1996;Young & Hayes 2004;Askey et al 2006), and trout are easier to catch in rivers with low-fishing pressure than in more heavily fished rivers (Young & Hayes 2004). However, Tsuboi & Morita (2004) found that whitespot char (Salvelinus leucomaenis, Salmonidae) that had been hooked and released were more likely to be caught than previously uncaught fishes, perhaps since they were initially the least risk-averse individuals. Cod remember the association between a stimulus and food for at least 3 months (Nilsson et al 2008a).…”
