Moringa oleifera fish feed and preparation method of moringa oleifera fish feed as well as culturing method of fish

Abstract

The invention discloses a moringa oleifera fish feed and a preparation method of the moringa oleifera fish feed as well as a culturing method of the fish. The feed is prepared from moringa oleifera, flour, lactic acid bacteria, saccharose and water. The preparation method comprises the following steps: during preparation, injecting aerated water into a fermenting tank for standing; then adding the lactic acid bacteria and the saccharose and uniformly stirring; fermenting for one day, uniformly mixing a fermented mixture with segmented moringa oleifera with tree age of two or above and the flour according to proportions; soaking the mixture in the fermenting tank for 30 minutes for fully adhering the lactic acid bacteria onto the moringa oleifera for feeding. According to the moringa oleifera feed and the preparation method of the moringa oleifera fish feed as well as the culturing method of the fish disclosed by the invention, the moringa oleifera feed is fermented and then fed, so that intestinal micropopulations are optimized, digestive absorption of grass carp is promoted and a traditional method of single feed or forage feeding is improved; the commercial adult fish is comprehensive in nutrition and the composition of amino acid is balanced; the meat quality and mouthfeel are improved, and the immunity of the grass carp is also improved.

Description

technical field [0001] The invention relates to a fish feed, in particular to a feed for grass carp for bulk freshwater fish cultivation, a preparation method of the feed, and a fish breeding method when the feed is used. Background technique [0002] Grass carp is one of the four major fish in my country, commonly known as grass carp, oil carp, grass carp, white carp, etc., and its English name: Grasscarp. Distributed in major water systems in my country, it is very popular in domestic and foreign markets. Grass carp can completely feed on aquatic higher plants when its body length is more than 10 cm. It is a typical herbivorous fish. The types of plants it eats also change with the status of food resources in the living environment. At present, grass carp is mostly fed with feed. The abuse of various antibiotics during the feeding process, and the impact of residual bait on the water quality of the culture, etc., can lead to a significant decline in grass carp meat qualit...
