Abstract:

A resource that is often used by the coastal communities of South Leitimur, Ambon City to fulfill their daily needs is mollusks. The community has long been utilizing the resources of mollusks (Bivalves and Gastropods), which are taken at low tide (bameti) to meet their daily needs as a substitute for animal protein other than fish. The existence of protected and economically valuable species and then with continuous community activities, without being balanced with knowledge of the importance of resource conservation will result in the vulnerability of the existence of these mollusc resources

Fossil mollusks are common and conspicuous objects in shallow marine strata of Ordovician and younger ages, and so the broad features of the post-Cambrian history of the Mollusca have been known for many years. However, as all but one of the eight classes of the Mollusca had evolved by the beginning of the Ordovician, it is obvious that the pre-Ordovician history of the Mollusca holds the key to an understanding of the primary radiation of the phylum. It was with this view in mind, that John Pojeta, Jr. and I began our joint studies of Cambrian mollusks some 13 years ago.

Line’s transect and plot methods were used to determining the structure of mollusks and vegetation by using index, diversity, and dominance as parameters. Intentional measurement were carried out on several biological parameters of the waters at 10 sampling points. From the observation and measurments, we obtained seven types of mollusk with 5644 individuals, where six types are belong to gastropods and one type is a member of bivalves.

The results of studying the influence of the content of Ca2+, Mg2+, Na+, and K+ cations in water on the level of lipid peroxidation products and antioxidants in the tissues of bivalve mollusks, D. bugensis and D. polymorpha, are presented. Mollusks were caught in four water areas of the Gorky Reservoir, which differ in the concentrations of Ca2+, Mg2+, Na+, and K+ cations. A correlation relationship has been established between the quantitative parameters of cations in water and the intensity of peroxide processes, on the one hand, and the level of general antioxidant activity in mollusk tissu

Abstract:

An unpredecented wave of extinctions is occurring at present, of which human activities are the main culprit. Habitat destruction and invasion by allochthonous organisms are likely the main causes for this loss of biodiversity. Mollusks are one of the main groups involved in these invasions, while likely one of those which has received their main impacts. Therefore, the study of mollusks from this viewpoint allows for a global and more comprehensive understanding of this problem. In this article, some paradigmatic cases of biological invasions by molluscs around the world are discussed.

The microbiological quality of samples was also checked through the isolation of Salmonella spp. and Escherichia coli.

This knowledge gap prompted us to study in more detail the bioaccumulation of phages by mollusks.
