A growth model of the cockle (Cerastoderma edule L.) tested in the Oosterschelde estuary (The Netherlands)
We present an ecophysiological model of the bivalve Cerastoderma edule that simulates individual growth and reproduction under ambient conditions in temperature and food availability in the Oosterschelde estuary, SW Netherlands. The model contains feedback loops in the uptake and metabolism of food and in the partitioning of carbon to the internal state variables: somatic tissue, storage, organ...
متن کاملEmergence pattern and spatial distribution of the common cockle Cerastoderma edule
When groups of freshly collected cockles Cerastodema edule L. were transferred to laboratory conditions and exposed to cycles of tldal emersion and immersion and a light regune of 12 h light. l 2 h dark, up to 40% of the group emerged onto the surface of the substratum during emersion at the onset of darkness. This pattern of emergence decreased in intensity from 37% to 10% of all individuals e...
متن کاملModelling of the Common European Cockle ( Cerastoderma edule L . ) fishing grounds aimed at sustainable management of traditional harvesting A
In the Bay of Saint-Brieuc, a 3110 ha tidal bay in NW France, English channel, the cockle (Cerastoderma edule) has been collected by traditional fishing methods for many decades without any evaluation or management of this resource taking place. Since 2001, the national Natural Reserve of the bay of Saint-Brieuc has carried out an evaluation of the stock and a mapping of the cockle fishing grou...
متن کاملImpact of two parasitic trematodes, Meiogymnophallus minutus and Himasthla spp., on the growth of the cockle, Cerastoderma edule
The impact of two principal parasitic digenetic trematodes, Meiogymnophallus minutus and Himasthla spp., on the growth (weight and length) of the cockle, Cerastoderma edule, in Arcachon Bay (France) was studied. The experiment was conducted in the land-based mesocosms. The velocity of infestation with both trematodes was far more rapid during summer in the cockles already parasitized with these...
متن کاملEffect of trematode parasites on cockle Cerastoderma edule growth and condition index: a transplant experiment
We quantified the effect of trematode parasites in cockles through a 303 d transplant experiment. Cockles were sampled in 3 different sites on the southwest coast of France characterized by 3 different trematode communities, i.e. Royan (RO): high Meiogymnophallus minutus abundance near cockle heart, South Arguin (SA): high Himasthla interrupta abundance in the mantle margin, and North Arguin (N...
