New research shows that dual small action cameras on ROVs more effectively provide data about the length of fish for a wider range of species than previous methods that use lasers.<\/strong><\/p>\n\n\n\n Reef fish communities in the northern Gulf of Mexico and U.S. Atlantic are comprised of a wide variety of ecologically and economically important fishes, including snappers, groupers, triggerfishes, and jacks.<\/p>\n\n\n\n Several aspects of these fishes\u2019 life history are related to length, including age, maturity, and egg production. Collecting length information, in addition to identifying which species and how many are present at each reef, can provide insights about population and community dynamics that can inform better assessments of stock, as well as an ecosystem\u2019s condition and productivity.<\/p>\n\n\n\n In short, collecting length information is a critical need for these species. For several years now, scientists have used remotely operated vehicles (ROV) to conduct underwater surveys of some of these fish populations.<\/p>\n\n\n\n But there is a problem.<\/p>\n\n\n\nResearch Need<\/strong><\/h3>\n\n\n\n
