Fish
Surveys
 The
Reef Watch Fish Survey method is known as a belt transect survey.
Divers swim in a straight line for 50m at a constant depth and record
the fish that they observe in a 5m belt (2.5m either side). The fish
surveys can also be completed in shallow water by snorkellers.
The fish
survey method is described more fully in the Reef
Watch Fish Survey Manual, which should be read in conjunction
with the Reef Watch
Site Manual.
The fish
sightings can be recorded directly on the Reef Watch fish
slate (to obtain a print quality version of this file,
contact Reef Watch)
Reef Watch has provided an on-line
information resource about these fish, including
identification notes.
To test
and improve your identification skills you can do the online
quiz, that shows pictures of different fish and prompts you
to select the correct species name from a list (see also advanced quiz
with scientific names).
The key reference for Reef Watch fish
identification is Sea Fishes of Southern Australia, by
Barry Hutchins and Roger Swainston, 1999 Swainston Publishing. The
authors have kindly allowed us to use their fish illustrations on the
Reef Watch fish slate and website.
There
are a number of other useful resources that can assist you with the
identification of fish, and provide further information:
