Publisher Summary This chapter focuses on the rearing of bivalve mollusks. The rearing of larval and juvenile bivalves requires an adequate supply of sea water of proper salinity and free of substances that may interfere with their normal development.

Acrosomal ATPase in starfish and bivalve mollusk spermatozoa
Experimental Cell Research, 1973Abstract ATPase activity was found in acrosomes of starfish and bivalve mollusk spermatozoa, using a cytochemical method with electron microscopy. The activity was located in central material of the starfish acrosome and in material lining the acrosomal membrane of the Mytilus acrosome, as well as in the basal part of the starfish acrosome.

The impact of microplastics on bivalve mollusks: A bibliometric and scientific review
Marine Pollution Bulletin, 2023Bivalves are important members of the ecosystem and their populations are declining globally, making them a concern for their role in ecosystem services and the fishing industry. Bivalves are excellent bioindicators of MPs pollution due to their widespread distribution, filtering capabilities, and close association with human health. Microplastics (MPs)

Bivalve Mollusks as Hosts in the Fossil Record
2021Parasites are ubiquitous in modern ecosystems, occupy one of the most successful life modes, promote ecosystem stability, and, despite their typically diminutive size and lack of a mineralized skeleton, are commonly identifed in the fossil record. Bivalve mollusks have occupied marine aquatic environments since the Cambrian, comprise an excellent ...

Environmental and Evolutionary Stability in Bivalve Mollusks
Science, 1974There is no relationship between environmental stability [as indicated by infaunal (stable) versus epifaunal (unstable) habits] and the generic duration of extinct marine bivalve mollusks when the effects of cosmopolitanism (which is associated with long generic durations) and other paleontological "noise" are excluded.

Molecular Detection and Genetic Analysis of Betanodaviruses in Bivalve Mollusks
Journal of Biotechnology, 2010Betanodaviruses are small ssRNA viruses responsible of Viral Nervous Necrosis in marine fishes worldwide. In this study, we examined bivalve mollusks for the presence of Betanodavirus and genetically analyzed the detected viruses to find out whether these animals could be a source of genetically closely related Betanodaviruses transmissible ...

Succinate and lactate oxidoreductases of bivalve mollusks
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1975Abstract 1. 1. Succinic acid is a major end product of anaerobic glycolysis in mollusks, and lactic acid is a minor product. On the hypothesis that production of these acids is partially controlled by properties of the enzymes catalyzing the final step in each pathway, extracts of the adductor muscle were prepared and used in oxidoreductase ...

Heavy Metals in Bivalve Mollusks
2017This chapter reviews the concentrations of several major metal contaminants in bivalve mollusks collected from different regions of the world. Bivalve mollusks considered in this chapter include oysters, mussels, scallops, and clams, all of which are the major seafood products in the world.

Microplastics in global bivalve mollusks: A call for protocol standardization
Journal of Hazardous Materials, 2022A growing body of evidence shows that microplastic pollution is ubiquitous in bivalve mollusks globally and is of particular concern due to its potential impact on human health. However, non-standardized sampling, processing, and analytical techniques increased the difficulty of direct comparisons among existing studies.

Bivalve Mollusks: Fluid Dynamics of Burrowing
Science, 1966When bivalves burrow into soft substrates the foot is first extended and then dilated to obtain a firm anchorage before retraction pulls the shell downward. Pedal dilation is principally caused by adduction of the valves. The hinged shell functions as a hydraulic machine in which the strength of the adductor muscles is transferred to the distal part of
