Embodiment
Below in conjunction with preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
In one embodiment, a silver carp rearing method of growing fast, the step of the silver carp rearing method that described growth is fast comprises: (1) pond is selected: the area of fingerling pond is 4-8 mu, depth of water 1.5-2 rice, the ridge, pond is solid water-tight, answers organic fertilizer material to cultivate before putting in a suitable place to breed;
(2) fingerling stocking: pond water temperature stability is at 18 ℃, and fingerling is thrown in specification and is 100-200 grams/fish, and breeding density is 0.4-0.5 Wei/㎡;
(3) feeding and management: mainly take plankton as foodstuff, Chi Shui requires fertile, it is many that plankton amount is wanted, pond is removed and is put in a suitable place to breed outside front basal dressing, after putting in a suitable place to breed, also want green manuring and ripe muck, in conjunction with regularly noting new water, make water maintenance breen, during raising, artificial throwing is raised needs regularly, locates, determines matter, quantitative, improve the availability of bait, reduce feed coefficient;
(4) daily management: patrol the pool every morning once, protection pond health; Draw in the net to check the situations such as the growth of fish and fish disease, thereby rationally establish daily ration, feeding quantity and fish disease prevention and cure method, carry out anti-ly escape, antitheft and fish disease, harmful animal preventing and controlling;
(5) disease prevention and cure: with 0.4ppm trichlorphon full pool spilling head prevention parasite, monthly once adopt 30ppm quicklime or 1ppm bleaching powder full pool spilling head prevention bacteriosis the 4-10 month.
