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
