“…Additionally, fish with larger home ranges have a higher capture probability [ 63 ]. Once caught by angling and released, fish can remember the experience and may exhibit hook avoidance [ 29 , 64 ]. Fish can forget threatening stimuli, with forgetting times ranging from 8 to 55 days without reinforcement [ [64] , [65] , [66] ].…”

“…Fish can forget threatening stimuli, with forgetting times ranging from 8 to 55 days without reinforcement [ [64] , [65] , [66] ]. However, some species, like the common carp ( Cyprinus carpio ), can retain this memory for up to six months [ 29 ]. This information can help target specific behavioral traits in the catfish population, or conversely, avoid using bait that has previously been used on catfish that were caught before.…”

“…Further, iii) we conducted experiments with different types of baits, aiming to identify significant differences in catch efficiency associated with each bait. Additionally, iv) we tested the selectivity of the long-lines on subgroups of populations with a certain pattern of behavior [ 28 ] and assessed its effectiveness in preventing fish from avoiding the hook after a previous catch [ 29 ]. Lastly, v) we compared the effectiveness of the long-lines with other fishing methods.…”

“…Therefore, we suggest that the small groups of carp we found in the summer may provide them with valuable information regarding resource distribution in the lake. Carp are also quick to learn from trained demonstrators [80,83,133], and can retain socially learned information for up to half a year [134].…”

Background Animals are expected to adjust their social behaviour to cope with challenges in their environment. Therefore, for fish populations in temperate regions with seasonal and daily environmental oscillations, characteristic rhythms of social relationships should be pronounced. To date, most research concerning fish social networks and biorhythms has occurred in artificial laboratory environments or over confined temporal scales of days to weeks. Little is known about the social networks of wild, freely roaming fish, including how seasonal and diurnal rhythms modulate social networks over the course of a full year. The advent of high-resolution acoustic telemetry enables us to quantify detailed social interactions in the wild over time-scales sufficient to examine seasonal rhythms at whole-ecosystems scales. Our objective was to explore the rhythms of social interactions in a social fish population at various time-scales over one full year in the wild by examining high-resolution snapshots of a dynamic social network. Methods To that end, we tracked the behaviour of 36 adult common carp, Cyprinus carpio, in a 25 ha lake and constructed temporal social networks among individuals across various time-scales, where social interactions were defined by proximity. We compared the network structure to a temporally shuffled null model to examine the importance of social attraction, and checked for persistent characteristic groups over time. Results The clustering within the carp social network tended to be more pronounced during daytime than nighttime throughout the year. Social attraction, particularly during daytime, was a key driver for interactions. Shoaling behavior substantially increased during daytime in the wintertime, whereas in summer carp interacted less frequently, but the interaction duration increased. Therefore, smaller, characteristic groups were more common in the summer months and during nighttime, where the social memory of carp lasted up to two weeks. Conclusions We conclude that social relationships of carp change diurnally and seasonally. These patterns were likely driven by predator avoidance, seasonal shifts in lake temperature, visibility, forage availability and the presence of anoxic zones. The techniques we employed can be applied generally to high-resolution biotelemetry data to reveal social structures across other fish species at ecologically realistic scales.
