The unutilized and unproductive lands in alkaline and waterlogged areas can be used for income and employment generation through fisheries activities. Apart from the income generation, the reclamation of the land is also possible if the scientific practices are followed. Karnataka is bestowed with vast variety of water resources for fisheries activities, saline, alkaline and waterlogged areas are also present is large extent in the state where the land is unused in majority of the affected areas. In this study, Krishna command area was selected for demonstration of composite fish culture using alkaline and waterlogged lands. Four beneficiaries were identified and empowered on using of these affected areas for fish culture. They were provided with quality carp seed and 2 tons of supplementary feed to each and scientific fish culture practices were demonstrated. Meanwhile, the water quality, fish survival, health and growth were monitored throughout the demonstration period. The pH of the water gradually decreased from 8.9 to 7.5, majorly due to addition of organic load to the pond. Other water quality parameters were scientifically monitored and they exhibited a decreasing trend with optimal limits favoring to fish culture. Catla, sliver carp, grass carp, common carp and amur carp showed a better growth rate with others being in moderate condition. The total mean fish production was found to be 3.8 t/acre from the demonstration sites and with the mean gross revenue of 4.25 lakhs. [ABSTRACT FROM AUTHOR] |
