Abstract:
Invertebrates possess some pronounced pharmacological activities or other properties which are useful in the biomedical area. In the present study, antimicrobial activities were observed in a fresh water clam, Villorita cyprinoides against a number of pathogens. Antimicrobial activities were carried out by standard disc diffusion method using the hemolymph and whole body extract of the clam Villorita cyprinoides, extracted using the solvents ethanol, methanol, butanol, ethyl acetate, chloroform, acetone, hexane and water. The whole body extract showed a high inhibitory action (20 mm) against t

Abstract:
Estuaries are among the most commercially significant ecosystems on the earth, and they provide different habitats for numerous bivalve species. The Clams are one of the most widely distributed and used aquatic bivalves, providing much more protein-rich food than mussels and oysters. The Vembanad Estuary is one of the richest clam fisheries coastal wetland in Kerala. The present study focusing on comparatives ofmorphology and biochemistry of Villorita cyprinoides and Meretrix casta shells in Vembanad Estuary. It also attempts to understand the variations in clam distribution caused by salinity

Abstract:
The Anchuthengu-Akathumuri backwater system in Kerala, India, is vital for local livelihoods but faces increasing pressures from tourism and urban development, threatening water and sediment quality. This study assesses microbial contamination in water, sediment, and the bivalve Villorita cyprinoides over a year (February 2022 to March 2023) at five sampling stations with varying levels of human influence. The study employed a combination of field and laboratory methodologies, including monthly sampling of water and sediment from five stations, followed by microbiological analysis using standa

The aim of the present study was to investigate the conjugal transfer of the blaCTX-M-1 gene from Escherichia coli to E. coli and from E. coli to Salmonella enteritidis serovar Enteritidis in Villorita cyprinoides and Penaeus monodon at different temperatures. An E. coli strain (N13) harbouring the blaCTX-M-1 gene was used as the donor strain. The recipients were E. coli (EF2) and S. Enteritidis (S3), both nalidixic acid-resistant strains of shellfish origin. Antibiotic susceptibility testing, minimum inhibitory concentration (MIC) determination and PCR detection of the blaCTX-M-1 gene were pe

Abstract:
Fishery products, being excellent animal protein supplements, can be easily availed by all sections of people and have served to meet the nutritional requirements of population since time immemorial. However, the geometric expansion o f the global population and the slow er growth rate of the world's food production leaves a large gap between the nutritional demands and supply, especially in the developing and under-developed countries.

Abstract:
With the situation that the production by capture fisheries has reached or is reaching a state of maximum exploitation , it is rightly presumed that there would be a decline in production. In context with this situation, aquaculture has been found to be a supplementary source to cater to the increasing world needs for fisheries products. This has led to the upsurge in aquaculture practices in many countries including India.

Abstract:
Bivalves are notorious for their ability to bioconcentrate contaminants and hence they can be used as effective indicators for monitoring trace toxic contaminants in coastal waters due to their wide distribution, sessile life style, euryhaline nature, resistance to stress and high accumulation of wide range of chemicals and ease of sampling. Bivalve resources of Kerala State mainly include different species of clams, oysters and mussels. During 2005- 2006 period, the total bivalve landing was about 61280 tones, of which 75% was contributed by a single species, Villorita cyprinoides (bla

Abstract:
Clams are perhaps the most widely distributed and utilized aquatic invertebrates providing protein-rich food in much greater abundance than mussels and oysters. In India, their exploitation at present is limited to the natural resources which may get depleted in course of time. Clam culture has not been taken up in our country on any commercial or semi-commercial scale, though there is scope for it because of the availability of vast stretches of suitable areas as well as seed clams, either from nature or by producing them in hatcheries. Such a proposition may become imperative in futu

Abstract:
The bivalve clams are traditional seafoods occupying a leading share to the edible bivalve mollusks in the estuarine and marine ecosystems of India. Corbiculid clam Villorita cyprinoides (black clam) and venerid clam Paphia malabarica (yellow-foot clam) are recognized to be the common bivalve clam resources in the coastal areas of the southwest coast of India. The bivalve clams, though regarded as low-value by-catch, believed to possess valuable nutritional qualities and pharmacological properties.
