摘要

Multi-species foraging associations occur when one or more species forage together. However, these associations have not yet been studied during tool use in fishes. Observations were made of the graphic tuskfish Choerodon graphicus (De Vis 1885) in New Caledonia to determine whether other fishes attended it during tool-use events. A new subtype of attendant associations, "scavenging at anvil", formed during 15 of 16 tool-use events (94%). Six identifiable attendant families were observed: Acanthuridae (surgeonfishes; 3.7% of total attendant fishes), Balistidae (triggerfishes; 11.9%), Chaetodontidae (butterflyfishes; 9.6%), Labridae (wrasses; 19.3%), Pomacanthidae (angelfishes; 0.7%) and Pomacentridae (damselfishes; 54.8%). Anvil choice significantly influenced the assemblages of attendants (p = 1.982e-10) but the size of C. graphicus did not (p = .4658). C. graphicus sometimes chased attendants but attendants did not behave aggressively towards C. graphicus or other attendants. C. graphicus appeared to be disadvantaged when attendants distracted it during tool use or scavenged its food. Attendants benefitted when they obtained food they could not otherwise access. Attendants may have responded to visual cues such as appearance, body movements and sand clouds, and auditory cues such as the "clack" sound made when a mollusc was struck on an anvil. Future studies should assess the importance of multi-species fish foraging associations during tool use to the ecology of coral reefs.

Graphicus有时被追赶服务员，但服务员并没有对C.图形或其他服务员进行积极行为。 C.当服务器在工具使用或清除食物中时，图形似乎是处于不利的。当他们获得食物时，服务员受益，他们无法访问。服务员可能已经回应了视觉提示，如外观，身体运动和砂云，以及当软体动物被击中砧座时所做的“噼啪声”声音等听觉提示。未来的研究应评估多种鱼类觅食协会在珊瑚礁生态学期间的多种鱼类觅食协会的重要性。
