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
