The document describes methods for conducting roving diver surveys to estimate species diversity and abundance across marine habitats. Two divers conduct timed swims, recording observed fish using a semi-quantitative scale from single to many individuals. Species abundance is recorded on a datasheet along with a score based on observation time. Identification is aided by keys highlighting morphological features. Invertebrates are surveyed using a similar method focused on macroinvertebrates. Proper species identification requires learning indicator species, keys, and consulting identification materials.
