説明

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).

プロジェクトデータ

This project aims to collect and archive underwater videos of aquatic organisms in Lake Biwa using carp-mounted video-loggers.

タイトル Filming a documentary through carp-eyes: Observation of fish fauna in Lake Biwa using animal-borne video loggers
ファンデイング The project was supported by the River Fund of the River Foundation, a grant-in-aid of The Zoshinkai Fund For Protection of Endangered Animals, Japan (both held by MAY), and JSPS KAKENHI Grant Number JP15K07545 (held by KM).
Study Area Description The study area was located in northern part of the North Basin of Lake Biwa, Japan, and was enclosed with in the following coordinates: 35.287-35.454 N, 138.018-138.225 E. Samplings were made in five field experiments: an experiment in Oct 2016, another experiment in Nov 2017, and the other three experiments in Nov-Dec 2018.
研究の意図、目的、背景など(デザイン) This project was designed to collect biodiversity information of Lake Biwa using carp-mounted video-loggers. The videos provide valuable information about nature of fishes and other animals inhabiting the lake.

収集方法

Samplings were made through five field experiments using nine fish as follows: (1) an experiment using one fish in Oct 2016, (2) another experiment using one fish in Nov 2017, and (3) three experiments using six fish from Nov to Dec 2018. Animal-borne video loggers (DVL200L; 27 mm width, 116 mm length, 10 mm height and 57 g in air, or DVL400M130; 21 mm width, 68 mm length, 22 mm height and 47 g in air, Little Leonardo, Tokyo, Japan) were used to collect video footage underwater. The logger was molded into a float with an accelerometer (ORI400-D3GT; 12 mm diameter, 45 mm length and 9 g in air, or W190-PD3GT; 21 mm diameter, 116 mm length and 60 g in air, Little Leonardo), a VHF transmitter (MM-130B; 16 mm diameter, 60 mm length and 20 g in air, Advanced Telemetry Systems, MN) and a time-release system (RT4; 16 mm diameter, 25 mm length and 16 g in air, Little Leonardo), and was then mounted on the back of each carp using a plastic cable tie. The float was shaped to reduce drag and it provided just enough buoyancy to return the instrument package to the surface upon release. All carp were released near the site at which they were captured. The video loggers were set to start recording in the morning (6:00 or 7:00 JST) three (or five) days after the fish’s release. The recording duration was 6 hours for DVL200L and 11–12 hours for DVL400M130. On the fourth (or sixth) day, the float detached from the fish, floated to the water surface, and was retrieved.

Study Extent The study area was located in the northern part of the North Basin of Lake Biwa, Japan, and was enclosed within the following coordinates: 35.287–35.454 N, 136.018–136.225 E. This study was conducted from Oct 2016 to Dec 2018. Samplings were made through five field experiments as follows: (1) an experiment in Oct 2016, (2) another experiment in Nov 2017, and (3) three experiments from Nov to Dec 2018.
Quality Control Scientific names followed the GBIF backbone taxonomy (https://www/gbif.org/species/) and the Union of Japanese Societies for Systematic Biology (2003). To identify avian species in the study area, daily occurrence reports of birds, provided by Kohoku Wild-Birds Center, (Bird News; http://www.biwa.ne.jp/~nio/newsindex.html) were used as a reference.

Method step description:

  1. The video data was formatted in MP4 (3 or 6 Mbps, 30 fps) format. A total of 64 h of video was taken. Images that contained any aquatic animals were cropped from obtained video footage using iMovie software (ver.10.1.9, Apple, CA). Color values of the images were adjusted using the “Automatic Color Adjustment” tool in the software.
  2. All species were identified by the authors or by professional experts. If we could not obtain sufficient information to identify a species from the videos (e.g., a blurring due to fish movements), we classified the organism to a higher taxonomic level (e.g., order, class, and family) that could be specified with certainty.
