Population dynamics and secondary production of the cockle Cerastoderma edule (L.) in a backbarrier tidal flat in the Wadden Sea

[EN] The population biology of the bivalve Cerastoderma edule was studied by monthly sampling from April 1994 to September 1995 at Neuharlingersieler Nacken, a backbarrier tidal flat near Spiekeroog island (East Frisian Wadden Sea, North Sea). Four stations located along a tidal gradient from 56 to...

description [EN] The population biology of the bivalve Cerastoderma edule was studied by monthly sampling from April 1994 to September 1995 at Neuharlingersieler Nacken, a backbarrier tidal flat near Spiekeroog island (East Frisian Wadden Sea, North Sea). Four stations located along a tidal gradient from 56 to 80% immersion time were established in order to analyse cockle growth, mortality and production. The highest densities were recorded at the beginning of the study (1000-1250 ind. M-2) with an intense and progressive decrease through 1995. A spatial distribution pattern was observed during summer 1994, with juveniles (3-12 mm long) being found in the high intertidal whereas adults occurred along the middle and lower intertidal. Based on growth increment data from tagging-recapture experiments, the parameters of the von Bertalanffy growth curve were estimated to be: asymptotic length L∞= 40 mm, and growth constant K = 0.404 y-1. A growth ring was formed in summer (July-August 1994). Annual somatic production ranged between 38.16 and 59.33 g AFDW . m-2. y-1. Total mortality ranged between Z = 0.52 year-1 and Z = 3.03 year-1. The distribution of the population was affected by passive displacements of juvenile cockles from the upper part of the intertidal toward lower zones in combination with high mortality at the station farthest from the coast, probably resulting from mussels overlying

Al objeto de analizar su crecimiento, mortalidad y producción se establecieron cuatro estaciones a lo largo de un gradiente mareal, dispuestas en fondos sumergidos entre el 56 y el 80% del tiempo. Al inicio del estudio se registraron las densidades más elevadas (1000-1250 ind. m-2), produciéndose una disminución intensa y progresiva a lo largo de 1995. En el verano de 1994 se observó que los juveniles (3-12 milímetros de longitud) estaban localizados en la zona superior del intermareal, mientras que los adultos ocupaban las zonas más bajas. En base a los datos de incrementos del crecimiento obtenidos en experiencias de marcado y recaptura, se estimaron los siguientes parámetros de la función de crecimiento de von Bertalanffy: longitud asintótica L∞= 40 mm y la constante de crecimiento K = 0,404 año-1. Se observó la formación de un anillo de crecimiento entre julio y agosto de 1994. La producción somática anual osciló entre 38,16 y 59,33 g PSLC m-2.año-1. La mortalidad total osciló entre Z = 0,52 año-1 y Z = 3,03 año-1. La distribución de la población se vió afectada por movimientos pasivos de los juveniles desde la zona superior del intermareal hacia las zonas más bajas y por una elevada mortalidad en la estación más alejada de la costa, posiblemente ocasionada por el establecimiento de un banco de mejillonesThis work was supported by the Spanish Ministry of Education and Science (Grant PF93 37284469), by the Federal Environmental Agency, the Environmental Research Plan of the Ministry of the Environment, Nature Conservation and Nuclear Safety of Germany (Grant 03F0112A), and by the State of Niedersachsen.
