          Abstract

          Se estudió el ciclo estacional de una pradera mixta de Cymodocea nodosa y Caulerpa prolifera, así como el de la ictiofauna asociada, desde marzo de 2001 hasta abril de 2002, en Playa Dorada (Lanzarote, Islas Canarias, Atlántico oriental). Algunas variables estudiadas presentaron un claro comportamiento estacional (bimodal), con máximo en primavera-verano (abril-septiembre) y mínimos en invierno (diciembre-marzo). Así, la densidad de haces osciló entre 372 y 1014 haces m-2, la biomasa de C. nodosa entre 94 y 271 g PS m-2, la biomasa vegetal total entre 94 y 383 g PS m-2, y la longitud de hoja entre 10 y 18 cm. La riqueza media ictiológica fluctuó entre 0.7 y 5.3 especies por censo, y la abundancia total de individuos entre 2.0 y 144.0 ind 100 m-2. Aparece una clara correlación entre el ciclo anual de C. nodosa y los descriptores del poblamiento ictiológico de la pradera.

          Translated abstract

          The seasonal cycle of a mixed seagrass meadow of Cymodocea nodosa and Caulerpa prolifera and of the associated ichthyofauna was studied at Playa Dorada (Lanzarote, Canary Islands, eastern Atlantic) from March 2001 to April 2002. A seasonal (bimodal) cycle was clearly observed, with maximum values in spring and summer (April-September) and minimum in winter (December-March). Shoot densities oscillated between 372 and 1014 shoots m-2, the biomass of Cymodocea nodosa between 94 and 271 g DW m-2, total vegetal biomass between 94 and 383 g DW m-2 and mean leaf lengths between 10 and 18 cm. Mean fish richness fluctuated between 0.7 and 5.3 species and total fish densities between 2.0 and 144.0 ind 100 m-2. There was a clear correlation between the cycles of C. nodosa and the associated fish population.
