Opistobranquios del Parque Nacional Laguna de La Restinga, Isla de Margarita, Venezuela

Abstract

En el Parque Nacional Laguna de la Restinga las escorrentías de origen terrestre, en conjunto con la surgenciacostera, contribuyen a la generación de una gran cantidad de nutrientes presentes, lo que setraduce en una abundante concentración de fito y zooplancton. Esto favorece el desarrollo de una diversidadde invertebrados marinos en este cuerpo de agua. En este contexto, la elaboración de inventariosde moluscos opistobranquios es relevante, ya que en su mayoría, estos animales se consideran indicadoresde calidad ambiental. En este trabajo se muestrearon nueve localidades de la laguna: Entrada de lalaguna, Arapano, el Conchal, Mánamo, Salida del caño viejo, entrada de La Tortuga, La Tortuga, El Gatoy El Indio. Los ejemplares fueron recolectados con la ayuda de un equipo snorkel y mediante colecta manual.Se muestrearon diversos sustratos entre los cuales se incluyen rocas, fondo blando, muelles artificiales,macroalgas, esponjas, hidrozoos y raíces de mangle rojo (Rhizophorae mangle). Se identificaron26 especies de moluscos opistobranquios en la laguna, representantes de los órdenes Cephalaspidea,Sacoglossa, Anaspidea y Nudibranchia, aumentando así la diversidad de moluscos de la laguna.

The terrestrial runoff and the coastal upwelling in the National Park Laguna de la Restinga contribute to a high amount of nutrients present, which produce a large amount of phyto and zooplankton, favoring the diversity of marine invertebrates. In this context, the development of inventories of opistobranquios molluscs is relevant since in most cases, these animals are considered indicators of environmental quality. In this work, nine (9) localities of the lagoon were sampled: Entrada de la laguna, Arapano, El Conchal, Mánamo, Salida del caño viejo, entrada de La Tortuga, La Tortuga, El Gato and El Indio. The specimens were collected manually with basic snorkel equipment. Diverse substrates were sampled: rocks, soft bottom, artificial piers, macroalgae, sponges, hidrozoos and red mangrove roots (Rhizophorae mangle). Twenty six species of opisthobranch mollusks were identified, which are representative of the orders Cephalaspidea, Sacoglossa, Anaspidea, and Nudibranchia, increasing the diversity of malacological fauna for this coastal lagoon.
