Shrimp Seed - A Critical Problem Faced by Shrimp Farmers - A Cross Sectional Analysis

Seed is a major input in shrimp farming and all the farmers and entrepreneurs depend on hatchery seeds. For expansion of brackishwater shrimp farming, a regular and steady supply of quality shrimp seeds in large quantities at a given time for stocking Is essential. Hatcheries are the source for the supply of quality hatchery seeds and stocking wild seeds Is banned. Presently, in Tamll Nadu there ore 68 shrimp hatcheries with a production capacity of 3000 million post-larvae. The survey was carried out In Nagapattinam and Thanjavur In two districts of Tamil Nadu. A sample of 300 shrimp farmers was Interviewed randomly for the study. This paper presents the prbblems pertaining to shrlmp seed encountered by the farmers and suggestions to overcome the same. The problems encountered by the farmers in both districts were lack of assurance on quality seeds, non-existence of government agency for regulating the price of seeds, high cost of seeds, non-availability of seeds from research institutes, inadequate supply of hatchery seeds, mortality of seeds during transportation, mixed seeds and deceptive method of counting the seeds. Suggestions given by them to overcome the problems were that the government research institutes should set up some mare hatcheries and virus free Nauplius shoutd be supplied to the farmers, assurance about seed quality from research institute and production of improved broodstock from government research laboratories. Since wjthout a heaithy broodstock shrimp farmers cannot hope to get quality seed, PCR was suggested as a sensitive diagnostic tool for detecting viral infection but due to various gaps in training this tool has not been used with consistent results

Time series modeling for forecasting the adoption behaviour of shrimp farmers

Commercial shrimp culture has emerged as a prominent sector of the coastal economy of India by virtue of the foreign exchange returns, rural employment it generates, and the economic viability of the enterprise and high market demand for the produce. The present study was conducted in Nellore and Nagapattinam districts a/India 10 forecast the adoption a/scientific technologies for a period of 17 years from 2004-2020, by the shrimp farmers using time series statistical modeling. The background data collected from 1997 to 2003 on the adoption behaviour of the farmers formed the database for predicting the adoption behaviour of the technologies. The study revealed that of the two statistical methods employed, namely Holt linear model and Holt exponential smoothing model, the goodness of fit generated by the Holt linear model with an R2 value 0/0.97 exhibited a higher degree of model adequacy over the Holt exponential smoothing model which revealed that in the years 2019 and 2020, the overall extent of adoption exceeded 100 percent which implies the development of new technologies by the research system and its subsequent adoption by the farmers. Besides factors such as changes in demography, demands in the export and local markets would motivate the shrimp fanners in future to adopt more of the improved technologies for getting higher yields

Factors responsible for discriminating between high and low adopter categories of shrimp farmers

Shrimp farming on a commercial scale has come to be the main stay, of the coastal economy of the country. Scientific shrimp farming is characterised by the adoption of improved technologies for getting a better yield both in terms of quantity and quality. Adoption of improved technologies is dependent upon a host of factors such as the perceived attributes of the technologyr the cost of the technologies and the policy environment in which the technologies are adopted

Quality of media reporting of suicidal behaviors in South-East Asia

Background: Suicide is a major global public health problem whilst sensible media reporting in an important population-level prevention strategy. Objectives: We reviewed the quality of media reporting of suicidal behaviors in the World Health Organization (WHO)-South-East Asia Region (SEAR) countries. Methods: We searched and scrutinized the contents of 12 articles published from SEAR countries (5 from India, 4 from Bangladesh, one from Indonesia, one from Sri Lanka and one from Bhutan) against suicide reporting guidelines. Results: Five out of the eleven SEAR countries, media reporting of suicide has been studied. All the studies have been carried out in the last decade with gross heterogeneity in the methods. All the articles report about poor adherence to media guidelines for suicide by most of the newspapers. Most countries in the region either lack country-specific media guidelines or poor implementation and monitoring of guidelines or both. Conclusion: The quality of reports of suicidal behavior in the SEAR region is poor. There is a need to develop country-specific media reporting guidelines and stringent monitoring on it to improve the quality of media reporting on suicide which may be beneficial for the prevention of suicide in the region
