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 ...

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.

Kinetic model of cadmium accumulation and elimination and metallothionein response in Ruditapes decussatus

Environmental Toxicology and Chemistry, 2007
Abstract The aim of the present study was to determine the response of metallothionein (MT) during Cd accumulation and elimination in different tissues of the estuarine bivalve Ruditapes decussatus exposed to two nominal Cd concentrations (4 and 40 μg/L) for 40 d, followed by a depuration period of 50 d.

Effects of mixture of nanoparticles under different salinity in the clams Ruditapes philippinarum and Ruditapes decussatus

, 2015
Few studies have been done to determine the toxicity of Nanoparticles (NPs) on marine ecosystems and its effect on the biota. NPs interaction with Salinity, a major environmental factor, needs particular attention. Organisms in the Venice lagoon, the sampling site of this study, are subject to a wide range of salinity, yet little is known about the ...
