Parasites of the genus Perkinsus cause high mortality and economic losses in bivalves commonly produced in global aquaculture. Although the immune responses of oysters and clams naturally infected with Perkinsus marinus or Perkinsus olseni have been extensively studied, there is not much information on host response at the early stages of infection. In this study, we analysed how P. olseni infl...

Ultrastructural characteristics of the germ cells and accessory cells in testis during spermatogenesis and taxonomic values of mature sperm morphology of Ruditapes philippinarum were investigated by the transmission electron microscope and scanning electron microscope observations. The testis is the diffuse organ that consists of branching acini containing developing germ cells and accessory ce...

The musk fragrance Galaxolide® (HHCB) is widely used in personal care and household products. Its large use leads to a continuous release of the compound into aquatic environments. Although some studies on presence HHCB ecosystems biota have been conducted, limited data about its effects organism biomarkers are available. This study aimed at investigating both cellular biochemical clam Ruditape...

Cadmium (Cd) is being frequently detected in marine organisms. However, dose-dependent effects of Cd challenged unraveling the toxicological mechanisms to organisms and developing biomarkers. Here, on clams Ruditapes philippinarum following exposure 5 doses (3, 9, 27, 81, 243 μg/L) were investigated using benchmark dose (BMD) method. By model fitting, calculation BMD values was performed transc...

Abstract Shellfish are increasingly been looked at as sustainable food sources that provide additional ecosystem services. However, their role CO2 sinks or is still debated. To quantify it, shell accretion dynamics should be accounted for. the component usually calculated with allometric scaling, in most bivalve models. With this study, was added to a bioenergetic model of Manilla clam (Ruditap...
