(2) input of fry, in annual mid or late May, when the water temperature stability in pond is more than 18 DEG C, during for suitably throwing in
Between, throwing in density for Hypophthalmichthys molitrix is 60%, and Ctenopharyngodon idellus are 35%, more suitably puts into 5% Carassius auratuss, selects the Fish that specification size is consistent,
Generally 100-200g mono-, every mu of input 5000-8000 bar；
(3) feed for nursing, fry has just entered 2-3 days of pond mainly based on filter food zooplankton, also allows fry adapt to the water in pond
Matter, starts feeding Semen Allii Tuberosi slag and bean dregs for 3 days later, or pellet, soybean cake or Chara fragilis Desv., and the special herbivore of Fish,
Daily number of times of feeding is 4 times, and ratio of feeding every time is morning 30%, noon 30%, at dusk 20%, night 20%；
(4) Fish sterilization, was first embathed 5 10 minutes with 3.0% saline and carries out disinfection before fry is thrown and supports, and entered after the pool again
Periodically sterilized using formalin；
(5) pond cleaning, when in autumn, pond should keep water level at 2.5 meters about, periodically drags for the hay in pond
Fall.
In a preferred embodiment of the present invention, spend 5 days after sterilization in step (1) and again water is put to 70% deeply.
