Preparation method of cow-dung fish feed

Abstract

The invention discloses a preparation method of a cow-dung fish feed. The preparation method of the cow-dung fish feed comprises the following steps of pouring 1 kilogram of the Baiyibao feed fermentation agent into 50 kilograms of water so as to carry out dilution by performing uniform stirring; putting cow dung and a feed together into a blender, and mixing the cow dung and the feed by carryingout stirring-mixing for 2 minutes; and then, adding a strain dilution, and carrying out stirring for 6 minutes. When no blender is available, the preparation of the cow-dung fish feed is carried by performing stirring by using a shovel according to a less-to-more principal, namely pouring the strain dilution into a small amount of the feed and the cow dung, and carrying out uniform stirring untilno mass exists; pouring the small amount of raw material to be fermented into the remaining feed and cow dung, and carrying out uniform stirring until no mass exists; putting the mixed raw material tobe fermented into a plastic container or a cement pond or a pit lined with a plastic sheeting until the plastic container or the cement pond or the pit lined with the plastic sheeting is fully filledwith the mixed raw material to be fermented after bing tightly pressed; and then, exhausting air, carrying out sealing by using a plastic sheeting until the plastic container or the cement pond or the pit lined with the plastic sheeting is completely sealed, carrying out fermentation at an appropriate temperature of 25-35 DEG C for 5-10 days until no odor is produced and a smell of alcohol emerges so that the fermentation is successfully done. By fermenting the prepared cow dung and feed, the cow-dung fish feed is capable of improving water quality, as well reducing mortality of fry.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for making cow dung fish feed. Background technique [0002] At present, most aquaculture in my country uses existing feed to feed fish, or uses existing bait and earthworms, but feed and bait will have side effects on fish, such as polluting water quality, increasing germs in water, causing fish It grows slowly, suffers from skin diseases, lack of oxygen, and increases the number of deaths. However, it can increase the water quality and reduce the mortality of fry through the fermentation of cow dung and feed. Contents of the invention [0003] The object of the present invention is to provide a kind of cow dung fish feed preparation method, to increase water quality, reduce the mortality rate of fry. [0004] In order to solve the problems of the technologies described above, the present invention provides the following technical solutions: [0005] The invention provides...
