Abstract
Fishes are attracted to the reef mainly by visual sensors, light, acoustic signatures, chemical and chemosensory cues and shadows/shelter and feed availability. Different fish groups behave differently as they grow. For eg., barracudas remain in large shoals when juveniles but as they grow into larger adults they swim in groups of lesser numbers; similar instances are seen in spiny lobsters, gobiids, scorpion fishes, lion fishes and snappers. Smaller carangids, rabbit fishes and cardinal fishes continue to remain in the same populations in similar densities in all phases of their life. Therefore, an assessment should be made of selective species which are indicators of large assemblies, indicators of singular forms, and indicators of migrants and visitors separately, based on which judging the reef performance would be ideal.
