摘要

The aquatic fern Azolla (Azolla caroliniana) can be easily grown organically in North Eastern India due to favorable climatic conditions. This fern was fed to the grass carp, Ctenopharyngodon idella (Val.) as a step towards producing organic fish. In the study, Azolla was found to be a preferred feed by the grass carp and mean daily growth increment was recorded. The statistically paired t-test indicated that the final weight gain of grass carp in Azolla fed ponds were significantly higher (tcal=4.85***; df=13) than that of the control pond. The net profit for production of organic grass carp was calculated as 0.12 $/m2. It was concluded that the utilization of organic Azolla through grass carp is one of the best options for production of fish biomass from the aquatic habitat. This would also pave way for producing organic fish and help in bridging the gap between production and demand of organic fish in the country.
