Economic Impact of Periphyton-Based Stunted Fingerling Production in Arunachal Pradesh, India

Non availability of right type quality seed at right time in required quantity is major bottleneck for the growth of aquaculture in Arunachal and major portion of seed are being import from other nearby state especially Assam in particular. To make availability of good quality seed at right time having a regional acclimation for a longer duration in far flung areas of the state, the present investigation was conducted on low cost Periphyton (grown on paddy straw) based stunted yearling production technology to improve the survival and health of stocked material and their economic impact on the fish farmers of district West Kameng during 2018-2021. The average values of pond water quality parameters were observed to vary between both the culture ponds with a significant seasonal differences at all the sites and there were found a greater difference in average survival rate of both the commodities i.e. table size fish as well as stunted yearling during whole culture period. The involved cost of cultivation was recorded higher Rs. 4,70,000 / ha in stunted yearling culture in comparison to Rs.424,940/ha in thetable size carp culture while average gross benefit was just opposite, recorded higher Rs. 6,90,000/ ha in stunted yearling culture in comparison to Rs.199,960/ ha in table size carp culture with the same trend in BCR i.e. 2.46 for stunted fingerling production and 1.47 in the production of table size fishes respectively.
