Mass Mortalities Affecting Populations of the Yellow Clam Amarilladesma mactroides Along Its Geographic Range ArchiMer
Vazquez, Nuria; Fiori, Sandra; Arzul, Isabelle; Carcedo, Cecilia; Cremonte, Florencia.
The yellow clam Amarilladesma mactroides (Deshayes, 1854) is considered a vulnerable species since the mid-1990s. Populations have experienced mass mortalities throughout their entire range of distribution (23–41°S) along exposed sandy beaches of Atlantic South America. Detrimental anthropogenic impacts have further contributed to failure of populations to make a recovery. To determine the factors involved in these events, density prior to a mortality event was calculated and live yellow clams encompassingmost of its geographic range distribution were analyzed histologically to describe parasites and pathologies. Moreover, moribund specimens were analyzed by molecular techniques to test for the presence of the virus OsHV-1. A mortality event was recorded...

Recherches sur les maladies des mollusques d'élevage ArchiMer
Grizel, Henri.
Shellfish farming has evolved from a harvesting business to a sedentary farming business. This evolution was done in stages, the main ones being management of natural sites, farming and maturing juveniles and adults. The different stages can moreover still be observed in several countries.... Among the research to be developed, pathology may be crucial for maintenance and growth of shellfish farming.
