Social impact and women empowerment through mussel farming in Kerala, India

Mussel farming has gained popularity along the southwest coast of India with more than 3,000 women becoming owners of mussel farms. Vasanth Kripa and Vazhoor Gopalan Surendranathan show how training alone was not sufficient to motivate villagers to adopt a new technology; instead visual observations of the success of the technology are essential for removing the risk aversion attitude. Support from the government prompted women to form self-help groups. This led to group farming, which helped women overcome social inhibitions and prove their competence

Development of ancillary industries related to mussel farming in Kerala

The commercialization of mussel farming in Kerala has created more part-time jobs during the crop period and has also helped in the development of several ancillary industries. It Development of ancillary industries related to mussel farming in Kerala1219 is estimated that during 2005-06, in the threenorthern districts viz Kasaragod, Kozhikode and Malappuram, the farmed mussel production by the rack method was 7496, 211 and 399 tonnes (t) respectively. To support such extensive mussel farming, several ancillary industries have also developed and the impact is widespread

TO DETERMINE THE EFFICACY OF 0.12%CHLORHEXIDINE MOUTHRINSES IN REDUCING VIABLE BACTERIAL COUNT IN DENTAL AEROSOLS WHEN USED AS A PREPROCEDURAL RINSE DURING THE PANDEMIC ERA -A PROSPECTIVE CLINICAL PILOT STUDY

Background: In dentistry , aerosols being the major concerns that brings about transmission of infectious agents and harmful to patients and dentists . Thus the vigilant use of barriers, appropriate immunisation procedures all could safeguard the dental fraternity from the ill effects of aerosols. Aim: To Determine The Efficacy of 0.12% chlorhexidine mouth rinse as preprocedural rinse in reduction of bacterial aerosol contamination generated during Ultrasonic scaling in a closed operatory and compared with1% Povidone iodine rinse and without preprocedural rinse. Materials and Methods: Thirty patients were selected from Department of Periodontics, Sree Balaji Dental College and Hospital, Chennai. The subjects were grouped into A -10 patients each receive 1% POVIDINE IODINE mouth rinse and Group B of 10 patients received 0.12% CHLORHEXIDINE mouth rinse respectively as a pre-procedural rinse. Group C 10 patients without preprocedural rinse. The aerosols produced by the ultrasonic unit were collected on blood agar plates placed at 8 standard positions around the dental chair. These plates were sent for microbiologic analysis for the assessment of bacterial Colony Forming Units (CFUs) was evaluated and statistically analysed. Results: The significance of the study was both the mouthrinses reduced the bacterial colony forming units (CFUs) in aerosol samples. 0.12%Chlorhexidine mouth rinses were found to be superior to 1%Povidone iodine in reducing aerosolized bacteria when used preprocedurally. Conclusion: The study highlights the efficacy of preprocedural mouth rinses , during any dental treatment which generates aerosols, reduces the risk of cross- contamination within the dental operatory

Biology of Mactra violacea (Gmelin 1791) from Kerala, south-west coast of India

The surf clam Mactra violacea (commonly known as violet trough shell), is distributed all along the sandy beaches of north Kerala. It occurs in the surf zone, upto 75-100 m depth. It is a large clam (upto 80 mm) with high meat content and nutritive value which is collected and consumed by the local people. The biology of the surf clam was studied to understand its growth, edibility and potential for mariculture

Bivalve resources and its exploitation in Malabar

The Malabar region of Kerala (Kozhikode, Kannur, Mahe, Kasargod) has significant bivalve resources contributing to subsistence fisheries of the local population. Clams and oysters form the major resources in the estuaries and backwaters. The clams, Meretrix casta, Meretrix meretrix, Villorita cyprinoides, Paphia malabarica and the edible oyster, Crassostrea madrasensis form the major exploited bivalve resources of commercial significance

On-bottom culture of the green mussel Perna viridis in Kerala

Farming mussels by sowing the seed on the estuarine or coastal intertidal regions, a method which is popularly called on-bottom method of farming has become popular in Kerala.The profit made by villagers who have adopted rack method of farming has prompted other villagers to take up onbottom farming which does not require much investment other than the cost of seed. However, there is considerable risk since smothering by silt may lead to complete

Site selection for Mussel Culture

In India, most of the bivalves produced are fished from the natural stocks. At present green mussels are cultivated mainly in the states of Kerala and Karnataka., Production o f bivalves by mariciilture in India is very little compared to the rest o f the world. The major source for collection o f the seeds of the bivalves is through wild collection or through laying of clutch material as in edible oysters

Production and growth of cultchless oyster spat of Crassostrea madrasensis (Preston) for single oyster culture

In India, edible oyster (Crassostrea madrasensis) farming is being practised by several farmers in central Kerala employing the rack and ren method in the estuaries and backwaters. However, farmed oysters do not find ready marketability due to the high labour costs involved in handling and shucking. The Central Marine Fisheries Research Institute, Cochin, Kerala, has developed the hatchery technology for edible oyster spat production, both cultched and cultchless. Nevertheless, these have not been commercialised due to the fact that spat collection from wild is still the most feasible option in oyster farming. The aim of the present study was to produce cultchless spat in the farm site itself and rear it to commercial size for harvesting uniform sized regular, rounded single oysters

Mussel culture in backwaters of Kasaragod district, Kerala

Mussel culture is increasingly getting Popular in Padanna and Cheruvattur Panchayats In Hosdurg Taluk of Kasaragod district in Kerala, By virtue of the popularisation efforts made by the CMFR Institute. Initially this low cost technology Of farming was transferred to five groups with 15 To 21 farmers at Cheruvattur and Vallyaparamba, Mostly women groups
