“…We found longer-lasting and smaller groups of fish during the summertime in agreement with Hundt et al, [84], in particular during the nighttime. Our comparisons to a null model of behaviour [98] indicated that these clusters were not driven by attraction to similar locations at similar times, but were truly a result of attraction to the individual carp.…”

“…Carp are also known to be a social species, frequently found in groups [75,81,82], and can learn by social facilitation [83]. Their social aggregations have been found to be dynamic and feature small subunit groups [84]. Carp are generally thought to occupy littoral habitats during the spring and summer and move to deeper waters to overwinter in larger groups [81,[85][86][87].…”

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.

“…In some systems carp may have multiple spawning periods in the same year (Smith & Walker, 2004) which may result in multiple periods of immunosuppression (Buchtíková et al, 2011) as well as changes in host density. Carp are also known to aggregate at natural and artificial food sources (Hundt et al, 2022). Aggregation of carp at artificial feeding sites has been implicated as a contributing factor to outbreaks of CyHV‐3 and CEV coinfection in Pymatuning reservoir (PA, USA) and long‐term population impacts due to CyHV‐3 infection in Blue Springs Lake (MO, USA; Padhi et al, 2019; Thresher et al, 2018).…”

Cyprinid herpesvirus‐3 (CyHV‐3) is an important pathogen of common carp (Cyprinus carpio, carp) causing significant economic and ecological impacts worldwide. The recent emergence of CyHV‐3 in the Upper Midwest region of the United States has raised questions related to the disease ecology and host specificity of CyHV‐3 in wild carp populations. To determine the prevalence of CyHV‐3 in wild populations of fishes in Minnesota, we surveyed five lakes in 2019 in which the virus was known to have caused mass mortality events in carp from 2017 to 2018. A total of 28 species (n = 756 total fish) of native fishes and 730 carp were screened for the presence of CyHV‐3 DNA using specific qPCR. None of the native fish tissues tested positive for CyHV‐3 although the prevalence of CyHV‐3 in carp was 10%–50% in the five lakes. A single lake (Lake Elysian) with a 50% DNA detection rate and evidence of ongoing transmission and CyHV‐3‐associated mortality was surveyed again in 2020 from April to September. During this period, none of the tissues from 24 species (n = 607 total fish) tested positive for CyHV‐3 though CyHV‐3 DNA and mRNA (indicating viral replication) was detected in carp tissues during the sampling period. CyHV‐3 DNA was detected most often in brain samples without evidence of replication, potentially indicating that brain tissue is a site for CyHV‐3 latency. Paired qPCR and ELISA testing for Lake Elysian in 2019–2020 identified young carp (especially males) to be the primary group impacted by CyHV‐3‐associated mortality and acute infections, but with no positive detections in juvenile carp. Seroprevalence of carp from Lake Elysian was 57% in 2019, 92% in April of 2020 and 97% in September 2020. These results further corroborate the host specificity of CyHV‐3 to carp in mixed wild populations of fishes in Minnesota and provide additional insights into the ecological niche of CyHV‐3 in shallow lake populations of carp in North America.

“…shark chumming), garden bird feeding and garbage and waste management. Several studies have quantified changes in the social behaviour of wildlife at provisioning sites (Hundt et al, 2022; Jacoby et al, 2021; Smulders et al, 2021), but few have studied whether social behaviour is also affect away from the resource sites (e.g., Grubb, 1987). A recent study of green turtles ( Chelonia mydas ) revealed that during touristic feeding events, turtles showed atypical aggressive behaviour (Smulders et al, 2021), while another study found partial evidence for reduced connectivity in the preference networks of tiger sharks ( Galeocerdo cuvier ) at ecotourist provisioning sites (Jacoby et al, 2021).…”

Ephemeral Resource Availability Makes Wild Guppies More Social

Resource availability and sociality are tightly coupled. Sociality facilitates resource access in a wide range of animal species. Simultaneously, resource availability may change sociality. However, experimental evidence for resource-driven social changes in the wild, beyond local aggregations at the resource, remains scarce. Moreover, it is largely unclear how potential changes in sociality relate to the social foraging benefits obtained by individual group members. Here, we recorded immediate and prolonged changes in social dynamics following ephemeral food availability in 18 mixed-sex Trinidadian guppies (Poecilia reticulata) groups in natural rainforest pools. Using a counter-balanced within-group design, the social associations within each group was observed before, between and after ephemeral patch availability for two consecutive days. We show that groups increased their time spent socially two-fold following ephemeral food patch, but not control (empty) patch, availability. Groups with stronger foraging motivation, measured as the average proportion of fish feeding, showed a stronger increase in sociality. This resource-induced increase in sociality was still detectable the next day. Increase in the time spent socially by a group also positively correlated with the more frequent arrival at detected food patches for individual members of motivated groups, which, in turn, correlated strongly with individual food consumption. Our study causally demonstrates that changes in ephemeral resource availability can induce rapid, substantial, and prolonged changes in the social dynamics of wild fish and that this change positively correlated with individual foraging success. Further research is needed to investigate whether this social change is a cause or consequence of individual foraging success and why some groups respond more strongly than others.
