©2020 Biological and Chemical Oceanography Data Management Office.This dataset includes the abundance of diurnal and nocturnal fishes in areas where gnathiid isopods were collected using lighted plankton traps. Point and belt transect surveys were conducted between April and September of 2015 and 2016 from study sites surrounding the U.S. Virgin Islands, British Virgin Islands, and Puerto Rico. These data were used to examine the relationship among fish assemblages, gnathiid abundance, and host exploitation. To fully understand the role of gnathiid isopods in ...
Show moreDuring a concurrent study, our team deployed lighted plankton traps to collect gnathiid isopods (following the protocol of Artim and Sikkel, 2016) from shallow coral reefs (less than10 meters) surrounding the British & US Virgin Islands and Puerto Rico. Prior to light trap deployment, day and night surveys of fish abundance were conducted at each trap location (Artim et al., 2020). Briefly, point surveys consisted of fish counts within a 1.5 meter radius of each trap location. On St. John, belt surveys were conducted within a 5 x 5 meter plot. Both day and night surveys were conducted within 24 hours of trap deployment. Fish counts were recorded by snorkelers and divers on SCUBA.
Known Issues:
Measurements from plot borders to trap locations (columns “LeftSideDist” and “RightSideDist”) were not recorded for belt surveys.
