Partial Substitution of Fresh Microalgae with Baker’s Yeast (Saccharomyces cerevisiae) Enhances the Growth of Juvenile Ostrea edulis and Ruditapes decussatus

Proceedings
The hatchery culture of bivalve mollusks depends on feeding with fresh microalgae which represent up to 50% of the production costs. We investigated the growth performance of juvenile Ostrea edulis and Ruditapes decussatus under 15% and 30% replacement ...

Enhanced trace element concentrations in tissues of the clam Ruditapes decussatus transplanted to areas influenced by human activities (Ria Formosa, Portugal)

Scientia Marina, 2017
To examine the extent to which human activities near the Ria Formosa coastal lagoon influence the accumulation of trace elements (TE) in Ruditapes decussatus, individuals were transplanted from a natural bank located in the lower lagoon to three sites ...

Diversity of Vibrionaceae associated with Ruditapes decussatus hatchery in Tunisia

Annals of Microbiology, 2011
The diversity of Vibrionaceae was investigated in a Ruditapes decussatus hatchery located in the Tunisian coastal marine waters. Quantitative study of the bacterial flora, conducted in different compartments of the hatchery, revealed that the total bacterial count (TVC) and the presumptive Vibrio (PVC) increased during the summer, due to the rise of ...

Study the effect of low pH on Ruditapes decussatus (Mollusca: Bivalvia) [PDF]

, 2021
The grooved carpet shell clam (Ruditapes decussatus) is one of the most economically essential mollusks in Mediterranean lagoons and sandy beaches, with fisheries and aquaculture both contributing to its abundance. The goal of this research is to see how varying amounts of acidity affect this calcifying organism. 420 ppm (ambient control), 550 ppm, 750

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.

In situ potential use of metallothionein as a biomarker of cadmium contamination in Ruditapes decussatus

Ecotoxicology and Environmental Safety, 2009
Cadmium (Cd) and metallothionein (MT) concentrations were analysed in the gills and digestive gland of clams Ruditapes decussatus collected from two sites of the Gulf of Gabès (Tunisia) which differ by their degree of pollution. The effect of biotic (maturity stages, protein, sex and body mass) and abiotic factors (temperature, salinity, site and ...
