||BotCam: Design, testing and development of a fully automated stereo-video bottom camera bait station for ecosystem monitoring of bottom fish species

||CRCP ID 1112-04, Project Name: Long-term Monitoring of Exploited Bottomfish Populations, Principal Investigator: Rusty Brainard
||The Coral Reef Ecosystem Division (CRED) of the Pacific Islands Fisheries Science Center (PIFSC) has developed a remote camera bait station (BotCam) to be used as an independent, in-situ, ecosystem-based tool for fisheries research and management. The device was designed to monitor commercially important bottomfish species within the Hawaiian Archipelago, American Samoa, the U.S. Line and Phoenix Islands, the Marianas Archipelago, Johnston Atoll and Wake Atoll. Previous work done within the science center and in various collaborations with the center have shown bait stations to be effective instruments for monitoring fish stocks. The unit presented is the first of its kind to implement a stereo-video system capable of capturing video at depths up to 350 meters with no external light source. The system is fully automated and can be deployed and recovered from a variety of vessels, capturing up to four hours of high resolution stereovideo digital files. Building on work done over the past year on a first prototype, the design, fabrication and testing of a second prototype incorporating a stereo-video system for accurate measurements of both fish and benthic features was achieved. Based on the findings from the second prototype, a third prototype has been designed and is currently being tested. Further, a preliminary study of the unit's bait dispersal characteristics using visual cues was performed. Understanding the area affected by the bait is one of the keys to making bait stations an effective fisheries research and monitoring tool.
