Scientific aquaculture technology was demonstrated inPhailin-affected four adopted villages, namely Ambapur in Digapahandi Block;Daseipur in Sanakhemundi Block; Nuapada in Kukudakhandi Block andSujanasahi in Khallikote Block of Ganjam District, Odisha for enhanced fish production from ponds, and livelihood and nutritional security of tribal farmers of that area. Sixteen ponds with total water area of 11.6 ha and 186 beneficiaries were adopted by ICAR-Central Institute of Freshwater Aquaculture through the Department of Science and Technology, Government of India sponsored project. Fingerlings of Indian Major Carps (catla, Catla catla
49-64 mm & 1.97-2.68 g, rohu, Labeo rohita
38-52 mm & 0.9-2.54 g and mrigal, Cirrhinus mrigala
33-47 mm & 0.55-0.78 g) were stocked with density 5,000/ha and ratio catla: rohu: mrigal :: 1:2:1 in October, 2017. After a culture period of 6-8 months, the growth of C. catla
was 252-285 mm & 600-755 g, L. rohita
215-260 mm & 350-585 g and C. mrigala
195-250 mm & 380-530 g.
Fish harvests were done in different villages during April-May, 2018 and productions achieved were 1.8-2.9 t/ha/yr from a pre-adoption level of 0.6-1.1 t/ha/yr. Plankton productivity of ponds was increased from 0.8-1.8 to 1.8-2.4 ml/50 l of water with adoption of better management practices (BMP), which contributed to 2.53-3.18 times higher fish production from ponds. The present investigation revealed that the fish production can be increased from small seasonal village ponds through proper BMP and the rural economy can be strengthened through the development of small-scale fish culture enterprises.Pages: 336-341 | 395 Views 30 DownloadsDownload Full Article:
