- Situación actual del recurso pepino de mar en el Sistema Arrecifal Veracruzano, México Elizabeth Romero-Hernández Pedro C. Reyna-González Guadalupe Pantoja-Yepez Ciencias de la Tierra SAV density population Coral reefs sea cucumber Throughout snorkeling and scuba diving ten study zones (sampling banks established in previous re search by Instituto Nacional de Pesca - INAPESCA) were evaluated where the presence of the sea cucumber was reported. By line transect sea cucumbers were censed and collected to be measured and weighed, as well as their habitat characteris tics were recorded. A total of 138 stations in the Sistema Arrecifal Veracruzano (SAV), equivalent to 37.794 m 2 of reef area sampled in the north and south were analyzed. In just 25 sampling points there were found Holothuria floridana (associated to seagrass and sand habitat, 0-1.5 m deep, with total length average of 10.88 cm and fresh weight average of 64.09 g) and Isostichopus badionotus (associated to sand and live coral habitat, 1.5-15 m deep, total length average of 27.2 cm and fresh weight of 769.19 g) . The average density of the total banks evaluated was 0.008 ind.m -2 . Results indicate that sea cucumber population in SAV is fragmented (patchiness or aggregation sites) and is not susceptible of exploitation (low density of individuals per unit area). As a manag ement measure, some banks were suggested as potential sites in which there was a major presence of sea cucumber, with the purp ose of monitoring these areas and evaluate the density of the population. This research and its results offer a current stat us about the fishing potential of the sea cucumber so that in the future, it will allow the suggestion to investigate their culture fo r the natural repopulation for a sustainable use of this marine resource in the region. 2017 artículo científico 0717-3326 https://www.redalyc.org/articulo.oa?id=47954027007 es http://www.redalyc.org/revista.oa?id=479 Revista de Biología Marina y Oceanografía application/pdf Universidad de Valparaíso Revista de Biología Marina y Oceanografía (Chile) Num.3 Vol.52
