This is the story of fish farmer Azim, who overwintered carp fry on his farm and benefited economically. Farmers often underutilize their ponds in the winter. However, as fry do not eat much food or grow because of the low temperature, the pond can be stocked at a high density. When the temperature rises, the fry grow faster to make up the gap and can be sold to the producers of full-sized carp. In addition to economic benefits, this technology brings fish to the market earlier in the year than is typically the case, and overall yield increases as the fish have a longer grow-out period. Azim heard about the technology from Ali, a local service provider trained by WorldFish. Azim also told his neighbors about the technology to help them get more out of aquaculture.
