At this point the full length of the fish is 12-28mm, weight 70-250mg, larvae of fish culture is the most difficult part of the fostering process, often lower survival rate, at about 60%. In order to increase its survival rate, technical management should be strengthened during this incubation period. 1, nurturing pool Nurturing pool to rectangular cement pool as well, located in the water
