Underwater video and still-image dataset of fishes and other aquatic animals in Lake Biwa, Japan, observed via carp-mounted video loggers.

This is the first large dataset of underwater videos from which species occurrence and behavioral records of aquatic organisms were identified in Lake Biwa, the largest lake in Japan. We compiled 109 videos and 122 still-images of fishes, diving birds and shrimps. The images were cropped from videos taken underwater with animal-borne video cameras which were mounted on the backs of common carp. Our dataset includes records of 10 species, 4 genera, 2 families and 1 infraorder which includes mostly fish, several birds, and a crustacean. This dataset is published as a data paper in Ecological Research (see https://doi.org/10.1111/1440-1703.12158).
