Spring temperatures gradually picked up, broodstock began feeding, do a good job nurturing management, can promote its recovery physique, enhance disease resistance, promote gonadal development, laying a good foundation for broodstock breeding. 1. sub-pool stocking for timely understanding of the growth of broodstock, easy to arrange for adulthood breeding, should be at a water temperature of about 10 ℃ when the original concentrated in Datang breeding broodstock, transferred to a small pond breeding. Sub-ponds should be done before the pond Qingtang disinfection work, per acre (1 mu = 667 square meters, the same below) available lime 100 kg of water, tea bran 60 kg, breaking the flooding 48 hours after the Quanchiposa. Sub-pool can be good growth and development of broodstock and growth and development of broodstock separated in general
