From 2002 to 2004, the author used 10 greenhouses to use underground hot water as heat preservation energy, and carried out overwintering breeding of tilapia species for two consecutive winters. Under the unfavorable circumstances that the prices of production materials went up, through effective technical measures, The average output of 3200 kg / mu, the average profit of 8,000 yuan / mu, the average specifications of 75 ~ 135 g / tail results. Breeding techniques are summarized below. First, the winter breeding technology (
