The Nature Conservancy 1 article published in JoVE Environment Development of New Methods for Quantifying Fish Density Using Underwater Stereo-video Tools Christian Denney1, Ryan Fields1, Mary Gleason2, Richard Starr1 1Moss Landing Marine Laboratories, 2The Nature Conservancy We describe a new method for counting fishes, and estimating relative abundance (MaxN) and fish density using rotating stereo-video camera systems. We also demonstrate how to use distance from camera (Z distance) to estimate species-specific detectability.
