RESUMO

A tidepool fish taxocenose was characterized regarding to morphology, residence degree, constancy and abundance of species. It was verified of occurrence the distribution patterns of species in the tidepool, along all the intertidal zone and throughout the seasons of the year. It was also verified the food habits of the most abundant species, as well the influence of some environmental parameters upon taxonose. Fish collections and field observations were made ineight tidepools at Manguinhos Beach, Espírito Santo, Brazil, from December, 1983 to December, 1984. The fish taxocenose studied was constituiedby a whole of 35 species, distributed among 23 families. These species were grouped in three distinct category, according to their residence degree in tidepools. Eleven species werw considered primary residents, the Bathygobius soporator, Scartella cristata and Labrisomus nuchipinnis being the most abundante TMenty species werw considered secundary residents, xhe Stegastes dorsopunnicans, Acanthrus bahianus, Abudefduf saxatilis, Ahlia egmontis and Halichoeres poeyi being , the most Abundant. Four species were considered transeunts, the Eucinostomus sp. and Xenomelaniris brasiliensis being the most abundante In general,the tidepool fishes were small including as well asthe lnfluence of some environmental parameters upon taxocenose. Fish collections and field observations were made juveniles and adults of small size species (Gobiidae, Blenniidae, Labrisomidae) and juveniles of great size species ( Serranidae Muraenidae, Acanthuridae). This characxeristic is probably related to the small available space of tidepools. ...Note: The complete abstract is available with the full electronic digital thesis or dissertations
