Preparation method of fermented feed for mountain spring running water fish

Abstract

The invention discloses a preparation method of a fermented feed for mountain spring running water fish, and relates to the technical field of fishery breeding. A feed base material is prepared from the following raw materials in parts by weight of 15-20 parts of corn flour, 1-3 parts of fish meal, 2-5 parts of sweet potato powder, 1-2 parts of edible salt, 2-6 parts of soybean cake powder, 1.5-2.5 parts of fish oil, 2-4 parts of bran, 2-3.5 parts of hemocyte protein powder, 0.5-2 part of additive compositions, 2-5 parts of vitamin regulators, 25-35 parts of soybean oil, 1-3 parts of Chinese herbal medicine mixtures, 0.4-0.8 part of iron, 0.3-0.5 part of selenium, 0.5-0.8 part of copper, 0.3-0.8 part of zinc and 0.4-0.7 part of iodine. The feed can remarkably improve nutrition of fish, promote growth of the fish and reduce attack rate; Chinese herbal medicines are added into the fish feed, so that the survival rate can be increased, and the growth can be promoted; probiotics are concepts relative to antibiotics and are active microorganisms which can be directly fed to animals and can achieve the purposes of preventing diseases, promoting the growth of the animals and increasing the utilization rate of the feed through regulating gastrointestinal tract microecological balance of the animals, and the feed can effectively enable the fish to grow healthily and quickly.

Description

technical field [0001] The invention relates to the technical field of fish farming, in particular to a method for preparing fermented feed for mountain spring and running water fish. Background technique [0002] Spring water fish belongs to Cyprinidae, Cyprinidae, Dace subfamily, and a kind of fish in the genus of spring fish. Commonly known as: spring water fish, oil fish. Spring fish is a unique species in China. The body is long, the front is round, the back is slightly flattened, the front of the abdomen is relatively flat, and the back of the head is curved. The snout is round and blunt, the cleft is slightly triangular, the upper and lower lips are connected at the corner of the mouth, and there are many neatly arranged small horny protrusions on the lips; the lips are rolled into the mouth, and when the mouth is opened, the lips are turned outwards and expanded into a trumpet shape. This is adsorbed in other objects. The posterior lip groove is limited to the co...

Problems solved by technology

The currently produced fish feed can only provide fish with protein intake when fed to fish. However, fish are affected by various factors in the water, such as water quality problems, which lead to slow growth of fish, decreased body immunity, and tissue loss. Slow renewal, poor wound healing, susceptibility to disease, etc. may cause a large number of fish to die and cause irreparable losses
