Event Abstract Back to Event Evaluation of the community structure of a rockpool fish assemblage from Peniche (Portugal) using clove oil as an anesthetic Francisco Mattioli1*, Vera Laranjeira1, Susana L. Mendes1 and Nuno Vasco Rodrigues1 1 School of Tourism and Maritime Technology, Portugal The goal of this study was to provide the first scientific data of the intertidal ichthyofauna community of Peniche. In order to have an accurate assessment, anesthetics were used, since this method is more effective than visual census. Therefore, the ideal concentration of clove oil to be used as anesthetics for local rock pool fish was tested. Through laboratory experiments with some of the most common species in the area, the concentration 30 mg.L-1was considered ideal. A total of 4 rockpools were sampled between May and July 2012, in two different locations (2 in Praia da Gamboa and 2 in Portinho da Areia Norte), in Peniche (West of Portugal). A total of 508 fishes belonging to 17 different species were registered. Fish abundance, occurrence frequencies and sizes were registered and compared for the two beaches and for the respective tide pools. The most abundant species was Gobius n.sp. while the most frequent was Gobius paganellus. These two species represent 59.1% of all captured species. Praia da Gamboa was the location with the highest abundance of individuals while Portinho da Areia Norte was the location where larger individuals were collected. It was observed that the size of rockpools affects abundance and density of individuals. Substrate, number and type of shelters also affect density, abundance and the mean size of individuals. Considering the studies focusing on intertidal ichthyofauna worldwide are relatively scarce, and being this ecosystem absolutely crucial both for biological but also socio-economic reasons worldwide, a better understanding of this unique ecosystem is mandatory, so it is possible to understand it, in order to preserve it.
