Abstract

This study aimed to determine the diet of sea urchin Echinometra mathaei; inter-tidal zones of Chabahar coast of the Persian date Shahrivar 1391, during a period when the Persian date Farvardin 1392, at 3 stations were seasonal. Sea urchin fisheries have been transferred to the lab and then dissected under a microscope to identify the contents of the digestive tract of animals was carried out. The results of this study identify the algae present in the digestive tract vitriol and prioritize them according to type (brown algae - red - green), respectively. Such a result was obtained, with a variety of high-Sea urchin that feeds on the current growth and gonad production is also effective. On the basis of studies have noted that E.mathaei of brown algae (kelp, Sargassum) and red algae (Grasylarya) power to bring the results of this study also noted. In the E.mathaei Sea urchin species of brown algae is feeding on your location and the next priority of green and red algae, and sometimes other animals (larvae, crustaceans and corals) feeds.
