Introduction

Characteristics

The species of Dictyota are difficult to identify. Typically they form dense mats or loosely packed flat leaves that overgrow the substrate. All have branches that fork near their ends, with the tips rounded or pointed. Colour can vary from light to medium brown and/or green to blue-green, occasionally with bright blue tints.^[1]

Classification

Consists of 76 species.^[2]

Control

Members of the genus Naso, notably N. literatus - Orange Spine Unicornfish, Lipstick Tang
Members of the genus Siganus, notably S. doliatus - Blue-Lined Rabbitfish
Some members of the genus Diadema sp.

Reports of success are patching, likely resulting from the large number of Dictyota species and availability of other food sources. Physical removal by hand is a good method of control in severe outbreaks.
