Condizione ecologica di Ruditapes decussatus (Veneridae) e sua presenza in aree di raccolta nel Golfo di Olbia = Ecological status and occurrence of Ruditapes decussatus (Veneridae) in harvested sites within the Gulf of Olbia [PDF]

, 2010
A pilot study was performed in order to evaluate the ecological status of the clam Ruditapes decussatus and its occurrence in specific harvested areas within the Gulf of Olbia. Indeed, since 1998, stocks of this clam seems to be decreased, due to intense

Physiological responses and scope for growth of Ruditapes decussatus from Ria Formosa, southern Portugal, exposed to increased ambient ammonia

Scientia Marina, 2004
In this study we investigate the effects of exposure to increased ambient ammonia-N concentrations as a cause of decreased scope for growth and mortality of R.decussatus during the summer months in Ria Formosa, southern Portugal.

Routes of TBT uptake in the clam Ruditapes decussatus. II. Food as vector of TBT uptake

, 2002
Marine bivalves are exposed to contaminants via the aqueous phase, sediments and food. Nevertheless, the relative importance of these phases as uptake vectors of contaminants in these marine organisms has not been well studied.

Differences in the digestive biochemistry between the intertidal clam, Ruditapes decussatus, and the subtidal clam, Venerupis pullastra

, 2009
The present study was aimed to evaluate differences in physicochemical characteristics (pH and temperature optima) of the main digestive enzymes (amylase, cellulase, laminarinase, and protease) in two commercially important bivalves, the intertidal clam,

Histological study of the gonadal development of Ruditapes decussates (L.) (Mollusca: Bivalvia) and its relationship with available food

Scientia Marina, 2005
This article describes the effects of food availability on the sexual maturation of Ruditapes decussates through histological examination of the gonadal tissue. Three food rations were tested: High (H: 1 mg. organic matter.
