Wild Fish Conservancy has developed, applied, and refined tecttechniques for underwater videographic fish-documentation during the past year, investing in state-of-the-art analog and digital video recording, lighting, software, and presentation equipment and designing and custom assembling much of this equipment especially for this application.


Underwater videography is the most technologically advanced procedure used to document fish and their habitats. It permits passive documentation without injury to fish, and provides access to complex and shallow water (lateral) habitats that cannot be effectively surveyed using traditional techniques.† While uncomfortably low water temperatures, high flows, and turbid water may compromise the accuracy of traditional snorkel surveys, underwater videography allows a safe and comfortable survey resulting in more extensive, accurate, and thorough surveys.


The ability to document and reproduce underwater observations allows analysis and review of field observations in the laboratory to promote precise size, abundance, and species identification.† Underwater videography provides numerous opportunities for disseminating monitoring results and other underwater observations, including the incorporation of GIS and GPS; printing individual images as photographs or to make posters; emailing individual images and short movies; and mailing CDís with text, still images, and movies.† Informing and educating the public and resource managers is more effective when data are linked with images.
