dc.description.abstractFisheries in India is a very important economic activity and a flourishing sector with varied resources and potentials, which provides valuable foreign exchange and employment to the millions of people. Aquaculture is recognized as the best alternative to meet the world’s protein demand. Brackishwater aquaculture in India is concentrated around the culture of exotic, white leg shrimp, penaeus vannamei, however, has attracted the farmers’ attention because of its fast growth, low incidence of native diseases, availability of Specific Pathogen Free (SPF) domesticated strains and culture feasibility in wide salinity range. Constant growth of aquaculture production in recent years would contribute to reducing the fishing pressure on natural fish stock. Due to disease and poor farm management by the farmers resulted low production at farmer’s door. So, knowledge about new farming techniques and better management practices (BMPs) is a prerequisite for precaution of outbreak of disease and to get better yield.Currently P.vannamei culture is facing different issues and challenges to achieve sustainability related to iseases out breaks, lack of availability of quality seeds, high feed costs, unauthorized farming, international price fluctuation, less demand in the domestic market. If the farmers implement better managementpractices and biosecurity in Vannamei culture supported by the government policies, the sustainability can achieved. Keeping in this view with the broad objectives, this study was conducted in five taluks of Nagapattinam district. The total of 150 shrimp farmers were selected proportionally to the number of shrimp farmers of each taluk. Data were collected by personal interview with the help of well-structured and pretested interview schedule. The data were analyzed by using the computer package i.e. Statistical Package of Social Science (SPSS). The salient findings of the study are as follows: The half of the respondent (50.00 per cent) were middle aged. 80.67 per cent of shrimp farmers had undergone formal education ranging from primary to collegiate level and majority (86.67 per cent) of the respondents had shrimp farming as their main occupation and more than two-fifth (42.67 per cent) of the respondents had undergone farming experience range from upto 6 – 10 years. More than one-third (42.67 per cent) of the respondents were found to be medium farmers. The majority (20.67 per cent) of the respondents had the annual income ranging from Rs. 20,00,001 – Rs. 30,00,000 and 36.67 per cent of the respondents had the annual expenditure ranging from Rs. 10,00,001 – Rs. 15,00,000. The farming implements utilization is good among the shrimp farmers in Nagapattinam, because 89.33 per cent of respondents had medium level of shrimp farm implements. The extension agency contact (62.00 per cent), economic motivation (52.00 per cent), credit orientation (62.67 per cent), social participation (78.00 per cent), scientific orientation (70.67 per cent), risk orientation (72.66 per cent), mass media exposure (77.33 per cent), information seeking behaviour (68.67 per cent), innovativeness (65.33 per cent), decision making behaviour (80.00 per cent) and knowledge level (58.00 per cent) where reported at medium level. Better results were observed in respect of adoption of individual practices. Most of the respondents were found to have fully adopted three practices viz., water quality management (100.00 per cent), feed management (100.00 per cent), and shrimp health management (100.00 per cent). In the case of few practices viz., waste water management (53.33 per cent), Biosecurity measures (48.00 per cent) and farm hygiene management (27.33 per cent), a majority of the respondent reported as partial adoption. Further, it has been found that a few of the respondent have not adopted some of the practices viz., biosecurity measures (16.67 per cent), seed selection and stocking (16.00 per cent), farm hygiene management (14.67 per cent), waste water management (12.00 per cent). The majority (79.33 per cent) of the shrimp farmers felt poor quality seeds as reason for failure crop in shrimp culture as a main constraints in adoption of Vannamei farming followed by high tariff for electricity (75.33 per cent), high cost of chemicals and fertilizers (68.00 per cent), high feed cost (65.33 per cent), price fluctuations (64.67 per cent), prevalence of disease outbreak (60.00 per cent), running mortality (51.3 per cent), lack of cold storage facilities (46.00 per cent), short supply of water (43.33 per cent), high labour cost for harvesting (26.00 per cent), low net returns (25.33 per cent), lack of scientific knowledge (20.67 per cent) and non-availability of skilled labor (12.66 per cent). Out of the 19 independent variables, only 15 of the independent variables had positive relationship with dependent variable and remaining 4 variables exhibited negative relationship. Among 15 variables that exhibited positive relationship to the adoption, five independent variables viz., farming experience, farm implements, social participation, extension agency contact, mass media exposure and innovativeness had significant relationship at one per cent level. While economic motivation, risk orientation, credit orientation and knowledge had significant relation with adoption at 5 per cent levels. Six independent variables viz., shrimp farm size, annual income, annual expenditure, decision making behavior, scientific orientation, information seeking behavior had non-significant relationship with the dependent variable. Among 4 variables that exhibited negative relationship to extent of adoption that two dependent variables viz., occupational status and credit orientation had non-significant relationship with the dependent variable. Independent variables namely age had significant at 1 per cent level while educational status had significant at 5 per cent levels. Lack of good quality seed, high cost of chemicals and drugs, high cost of feed, price fluctuations, prevalence of disease outbreak, high electricity tariff, non -availability of skilled labor and lack of scientific knowledge were the important constrains for the non-adoption of different practices of vannamei farming. Shrimp farmers suggested that adequate credit facilitates, insurance coverage, extension of training period, adequate subsidy facilities, extension education effort and technical guidance would increase the adoption level of vannamei farming. The study was carried out to identify constrains for adopting the better management practices of vannamei farming and to draw suitable strategy to overcome or remove the barriers. This findings can be used to increase the adoption level of different better management practices of vannamei farming.en_US
