Diet of the black sea urchin Echinometra lucunter (Echinometra: Echinoidea) in the northeast of Venezuela.
Echinometra lucunter is relatively abundant in the Venezuela coast, however no details are known about its diet. We compare the stomach contents and repletion index of E. lucunter with macroalgae available in their environment (June 2010-August) and the nutrient cycle at the Golfo de Cariaco. Sevent...

| description |
Echinometra lucunter is relatively abundant in the Venezuela coast, however no details are known about its diet. We compare the stomach contents and repletion index of E. lucunter with macroalgae available in their environment (June 2010-August) and the nutrient cycle at the Golfo de Cariaco. Seventy-one species of macroalgae were identified: Rhodophyta (45), Heterokontophyta (11) and Chlorophyta (15). The mean testa diameter was 41.04 ± 6.60 mm. The food preferences included filamentous, siphonal and calcaeous macroalgae; main food items were the filamentous macroalgae Sphacelaria sp. and Herposiphonia sp., and foliose Dictyota sp., including invertebrates such as sponges, bivalves and barnacle crustaceans. The repletion index was 0.8 - 6.0 % (2.6 ± 1.21 %), maximum values were associated to primary productivity cycle, i.e. December 2010 (6.0 ± 2.21 %), April (4.3 ± 0.34 %), June 2011 (4.0 ± 1.79 %). Food preferences could be associated to the upwelling season and productivity cycle. |

Food preferences could be associated to the upwelling season and productivity cycle. Mensualmente entre junio 2010 y agosto 2011 en la ensenada de Turpialito, Golfo de Cariaco, Venezuela, se recolectaron macroalgas e identificaron, y ejemplares de Echinometra lucunter con diámetro de testa 41.04 ± 6.60 mm para examinar el contenido estomacal y el índice de llenado. Se identificaron 65 especies de macroalgas, pertenecientes a los Phylla Rhodophyta, Heterokontophyta y Chlorophyta. La mayor biomasa anual la presentaron Halimeda opuntia (56.5 g.m-2), Acanthophora spicifera (15.94 g.m-2), Sargassum vulgare (15.28 g.m-2) y Centroceras clavulatum (12.26 g.m-2). Los ítems alimenticios más frecuentes fueron las macroalgas filamentosas: Sphacelaria sp. (546) y Herposiphonia sp. (441) y la foliácea Dictyota sp. (410), y entre los invertebrados esponjas (155), moluscos bivalvos (70) y crustáceos cirrípedos (65). El ID osciló entre 0.8 y 6.0% (2.6 ± 1.21 %), con máximos en diciembre 2010 (6.0 ± 2.21 %), abril (4.3 ± 0.34 %) y junio 2011 (4.0 ± 1.79 %), con oscilaciones mensuales asociadas a los períodos de surgencia y estratificación. El conocimiento de las características principales de la dieta, es necesaria para proponer planes de cultivo y de conservación de la especie.
