Economic Analysis of Inland Fish Production in Northern Dry Zone of Karnataka

Indian fisheries and aquaculture is an important sector of food production, providing nutritional security to the food basket, contributing to the agricultural exports and engaging about 14 million people in different activities. The present study was aimed to analyze economic and financial feasibility of inland fish production in Vijayapur and Bagalkote districts of northern dry zone of Karnataka. Primary data required for the study was collected from 60 sample farmers, 30 from each district in the study area for the year 2018-19. Financial feasibility tools (Pay Back Period, Net Present Values, Internal Rate of Returns and Benefit-Cost Ratio) were used to fulfill the specific objective. The total capital investment in inland fish farming of per pond was Rs.73309. The total cost involved for fish production was highest in Vijayapur district Rs.46782.28/pond/year compared to Bagalkote district Rs.38794.6/pond/year. The inland fish farming was financially feasible in both the districts as evidenced by Pay Back Period which is less than two years, net present value Rs.264047.50 in Vijayapur and Rs.246991.9 in Bagalkote districts, B:C ratio (1.84) in Vijayapur district, (1.92) in Bagalkote district and internal rate of returns higher than the opportunity cost of capital with 43 per cent and 45 per cent in Vijayapur and Bagalkote districts respectively

Comparison of newly standardized ‘Latex milk agglutination test’, with ‘Indigenous milk ELISA’ for ‘on spot’ screening of domestic livestock against <i>Mycobacterium avium </i> subsp.<i> paratuberculosis</i> infection

511-517Mycobacterium avium subspecies paratuberculosis (MAP), the cause of Johne’s disease in animals, has also been associated with Crohn’s disease (CD), Inflammatory bowel disease (IBD) and auto-immune disorders of humans. Increased consumption of milk and milk products made from pasteurized milk led to the sharp rise in the cases of IBD/CD in India. Milk and milk products are the main source of transmission of MAP from animals to humans, since MAP is not inactivated during pasteurization. Lack of rapid and sensitive ‘field test’ is the major stumbling block in estimating bio-incidence of MAP and threat it poses to human population. In the present study, newly standardized ‘Latex milk agglutination test’ (LMAT) was compared with ‘Indigenous milk ELISA’ test. Of the 900 raw milk samples of domestic livestock screened, 36.4 and 51.4% were positive in milk ELISA and LMAT, respectively. In milk ELISA, 38.7, 71.4, 35.1 and 33.5% milk samples of goats, sheep, cattle and buffaloes were positive for MAP, respectively. Whereas in LMAT, 60.6, 90.4, 45.9 and 44.7% milk samples of goats, sheep, cattle and buffaloes were positive for MAP, respectively. LMAT had 70.5% overall rate of agreement with milk ELISA. LMAT had sensitivity and specificity of 80.1 and 65.0%, respectively on comparion with ‘Indigenous milk ELISA’ and Kappa value of 0.416. Strength of agreement between two tests was ‘fair’. Study showed that LMAT has potential to be developed as field based ‘spot test’ for the rapid screening of milk samples of lactating domestic livestock for the detection of MAP
