Nondestructive Monitoring of Soft Bottom Fish and Habitats Using a Standardized, Remote and Unbaited 360° Video Sampling Method

نویسندگان

چکیده

Lagoon soft-bottoms are key habitats within coral reef seascapes. Coral fish use these as nurseries, feeding grounds and transit areas. At present, most soft-bottom sampling methods destructive (trawling, longlining, hook line). We developed a remote, unbaited 360° video method (RUV360) to monitor species assemblages in soft bottoms. A low-cost, high-definition camera enclosed waterproof housing fixed on tripod was set the sea floor New Caledonia from boat. Then, 534 videos were recorded assess efficiency of RUV360. The technique successful bare soft-bottoms, seagrass beds, macroalgae meadows mixed soft-bottoms. It is easy particularly efficient, i.e., 88% stations sampled successfully. observed 10,007 belonging 172 species, including 45 targeted by fishermen Caledonia, well many species. results consistent with known characteristics lagoon bottom Caledonia. provide future users general recommendations reference plots estimate proportion theoretical total richness sampled, according number or duration footage.
