Abstract

This spatial coverage includes vector points and point labels that describe CORDIO and PRAREV in-water survey sites of the broader Djibouti Seascape. Each site has a set of fish and benthic community variables distinguishing it from the surrounding sites. These characteristics include site name, functional group, total fish biomass (kg/ha) and total fish abundance (individuals/ha).
