Abstract:
In order to assess the impact of cyanobacteria on mollusks under experimental conditions, the interaction of toxic and non-toxic strains of cyanobacteria Microcystis aeruginosa (Kützing) Kützing and bivalve mollusks Unio pictorum (L., 1758) was studied. Cyanobacteria have a negative effect on bivalve mollusks: 40% death of mollusks and deterioration of their adaptive capacity were recorded when co-cultivated with M. aeruginosa at a high cell concentration. At the same time, there was no difference in the mortality of mollusks incubated with toxic and non-toxic cyanobacteria. A decrease in the

Abstract:
Fouling by the recently established zebra mussel (Dreissena polymorpha) causes differential effects among bivalve communities. In 3-mo experiments and surveys conducted in western Lake Erie during 1990, two native bivalves, Lampsilis radiata and Amblema plicata, showed consistent differences in mortality and biochemical indices of fitness in response to fouling by D. polymorpha. Lampsilis radiata was very sensitive to fouling, experiencing high mortality and reduced fitness in experiments and natural populations. In field experiments, female L. radiata suffered higher mortality and lower fitne

Abstract:
White spot syndrome virus (WSSV) poses a major risk to shrimp aquaculture, and filter-feeding bivalves on shrimp farms may contribute to its persistence and transmission. This study investigated the bioaccumulation and vector potential of WSSV in Pacific oysters (Crassostrea gigas), blue mussels (Mytilus edulis), and manila clams (Venerupis philippinarum) cohabiting with WSSV-infected shrimp. Sixty individuals of each species (average shell lengths: 11.87 cm, 6.97 cm, and 5.7 cm, respectively) cohabitated with WSSV-infected shrimp (Penaeus vannamei, average body weight: 16.4 g) for 48 h.

Abstract:
The fan mussel, Pinna nobilis, represents the largest bivalve endemic to the Mediterranean Sea. Since 2016, dramatic mass mortality of this species has been observed in several areas. The first surveys suggested that Haplosporidium pinnae (currently considered species-specific) was the main etiological agent, but recent studies have indicated that a multifactorial disease may be responsible for this phenomenon. In this study, we performed molecular diagnostic analyses on P. nobilis, P. rudis, and bivalve heterologous host species from the island of Sardinia to shed further light on the pathoge

Abstract:
Background: The effects of climate change negatively affect marine bivalves’ health. Lately, the intensity of marine heatwaves poses serious threats to the aquatic environment setting of high-risk bivalve farming. Since temperature increases can jeopardize bivalves’ immunity response, pathogen infection becomes more evident. Reactive oxygen species (ROS) production, increased during the process of phagocytosis, is confronted by the animals’ antioxidant defense system. However, apart from pathogenic infections, antioxidant defense responses are also induced by seawater temperature increases; Me

Abstract:
The densities of two common intertidal/shallow subtidal bivalves, Soletellina alba and Arthritica helmsi, were sampled in vegetated and unvegetated habitats of the Hopkins River estuary on three occasions during the autumn/winter 1995. Winter flooding coincided with mass mortalities of the infaunal bivalve S. alba, but not A. helmsi. Mortalities were apparent for individuals living deeper in the sediment (≈35 cm) in vegetated and unvegetated habitats, but small S. alba (&lt;1 mm) were less susceptible to mortality than larger individuals (&gt;1 mm). Mortalities were similar across different ha

All else being equal, species with short life spans are expected to be overrepresented in time-averaged death assemblages relative to their standing abundance in the living community, but the magnitude of the distortion of proportional abundance and assemblage evenness has received little attention. Here, information from 30 data sets on the living and dead abundances of marine bivalves in local habitats is combined with a global compilation of bivalve life spans to determine whether bias from mortality rate can explain observed differences in species proportional abundances.

Abstract Control strategies for established populations of invasive alien species can be costly and complex endeavours, which are frequently unsuccessful. Therefore, rapid-reaction techniques that are capable of maximising efficacy whilst minimising environmental damage are urgently required. The Asian clam (Corbicula fluminea Müller, 1774), and the zebra mussel (Dreissena polymorpha Pallas, 1771), are invaders capable of adversely affecting the functioning and biodiversity of freshwater ecosystems. Despite efforts to implement substantial population-control measures, both species continue to

I molluschi bivalvi sono animali filtratori che possono accumulare nei loro tessuti anche microrganismi patogeni presenti nell'ambiente circostante (batteri, virus e parassiti), quest’ultimi possono causare uno stato di malattia che nei casi più servi può portare alla morte, evento percepita dal molluschicoltore come “mortalità anomala”. Negli ultimi anni è stato dimostrato come siano soprattutto fattori ambientali, quali variazioni di temperatura e salinità dell’acqua, a concorrere nel favorire l’indebolimento del mollusco a favore del patogeno.

Phylum Mollusca is a large and diverse group of invertebrate protostomes of over 85,000 species including gastropods, cephalopods and bivalves. Molluscs are the largest marine phylum. Marine molluscs are economically important as a high protein food source for humans and provide ecosystem services including nutrient recycling, carbon sequestration, sediment stabilisation and bioturbation. Molluscs are harvested by traditional fishing but are increasingly cultured in many coastal communities worldwide. Hence most information on pathogens and disease is known in molluscs of commercial significan
