Carry‐Over Effects of Broodstock Conditioning on the Salinity Tolerance of Embryos of the New Zealand Geoduck (Panopea zelandica)

Aquaculture Research, Volume 2024, Issue 1, 2024.
The New Zealand geoduck (Panopea zelandica) has seen considerable interest from the NZ aquaculture industry. A major bottleneck in culturing P. zelandica is early life stages mortality (e.g., embryo). Therefore, in this study, we investigated the embryonic performance and their transition to the first feeding larval stage (D‐veliger) under different ...

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

Struttura di popolazione di vongola verace (Ruditapes decussatus l.) in due lagune costiere della Sardegna = Population structure of carpet shell clam (Ruditapes decussatus l.) in two coastal lagoons of Sardinia (Italy) [PDF]

, 2011
Ruditapes decussatus L. (Bivalvia) is a traditional resource for fishing activity in Sardinia Island. This species is not cultured, but fishermen pick them up from the bottom of brackish areas.

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 ...

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 ...

Comparison of metallothionein induction in response to cadmium in the gills of the bivalve molluscs Mytilus galloprovincialis and Ruditapes decussatus

, 1998
Metal binding characteristics and metallothionein induction differ markedly among the gills of the bivalve molluscs Mytilus galloprovincialis and Ruditapes decussatus exposed to sublethal cadmium concentrations (100 μg/l).

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.
