Signatures of Selection for Resistance/Tolerance to Perkinsus olseni in Grooved Carpet Shell Clam (Ruditapes decussatus) Using a Population Genomics Approach [PDF]

open access: yesEvolutionary Applications
The grooved carpet shell clam (Ruditapes decussatus) is a bivalve of high commercial value distributed throughout the European coast. Its production has suffered a decline caused by different factors, especially by the parasite Perkinsus olsenii ...

Comparative study of gonadal development of Ruditapes philippinarum (Adams and Reeve) and Ruditapes decussatus (L.) (Mollusca: Bivalvia): Influence of temperature [PDF]

open access: yesScientia Marina, 2007
Laboratory experiments were used to study the influence of temperature on the reproductive behaviour of two species of clam, Ruditapes decussatus and Ruditapes philippinarum, during their adaptation to the temperature conditions of Galician coastal ...

Effect of TBT on Ruditapes decussatus juveniles

open access: yesChemosphere, 2006
The effects of sublethal concentrations of tributyltin (TBT) on growth of juvenile clams Ruditapes decussatus were determined during exposure to TBT concentrations of 50, 100 and 250 ng l(-1) (as Sn) for a period up to two years. Length and weight of clams increased continuously in all treatments throughout the experimental period, and, overall, rates ...

Metallothioneins in the clam Ruditapes decussatus: an overview [PDF]

open access: yesAnalusis, 2000
coastal waters. Due to its economic importance it is extensively cultured in many countries, and particularly in Portugal where its production represents > 80 % of total shellfish production. The selection of the clam R. decussatus as a bioindicator was a consequence of its economic importance and the need to use a filter-feeding bivalve to evaluate ...

Isolation and characterisation of metallothionein from the clam Ruditapes decussatus [PDF]

open access: yesAquatic Toxicology, 2003
Metallothioneins (MT) were obtained after purification from metal-exposed clams (Ruditapes decussatus) using gel-permeation and ion-exchange chromatography. Four cadmium-metallothioneins (CdMTs) were resolved by ion-exchange chromatography and they all had similar molecular weights, high cadmium content and an absorption spectra indicative of the ...

Toxicity of silver nanoparticles on the clam Ruditapes decussatus assessed through biomarkers and clearance rate

open access: yesMaterials Research Express, 2021
The current bioassay aims the evaluation of the ecotoxicity of the silver nanoparticles (NPs) (100 and 200 μ g l ^−1 ) on Ruditapes decussatus after 48 h and 7 days of its exposure.

Microencapsulated Diets as an Alternative to Bivalve Feeding: Particle Size and Microalga Content Affect Feed Intake [PDF]

open access: yesAnimals, 2023
Bivalve mollusks represent a nutritious source with a low environmental impact; as a result, they are one of the most attractive aquaculture options. Advances in microencapsulation technology offer great potential to face key bivalve nutrition problems ...

A microarray-based analysis of gametogenesis in two Portuguese populations of the European clam Ruditapes decussatus. [PDF]

open access: yesPLoS ONE, 2014
The European clam, Ruditapes decussatus is a species with a high commercial importance in Portugal and other Southern European countries. Its production is almost exclusively based on natural recruitment, which is subject to high annual fluctuations ...
