This study compared remote underwater video and traditional direct diver observations to assess reef fish feeding impact on benthos across multiple functional groups within different trophic categories (e.g. herbivores, zoobenthivores and omnivores) and in two distinct reef systems: a subtropical rocky reef and a tropical coral reef. The two techniques were roughly equivalent, both detecting the species with higher feeding impact and recording similar bite rates, suggesting that reef fish feeding behaviour at the study areas are not strongly affected by the diver's presence.
本研究比较了远程水下视频和传统的直接潜水员观察，以评估不同营养类群（如草食性、底栖动物食性和杂食性）多个功能群的珊瑚礁鱼类对底栖生物的摄食影响，研究地点涉及两个不同的珊瑚礁系统：亚热带多岩石的珊瑚礁和热带珊瑚礁。这两种技术大致相当，都能检测到摄食影响较大的物种，并记录出相似的摄食率，这表明研究区域内珊瑚礁鱼类的摄食行为并未受到潜水员存在的强烈影响。
