Fish feed for rice field fish culture and preparation method thereof

Abstract

The invention discloses a fish feed for rice field fish culture. The fish feed comprises the following raw materials: bean pulp, cotton pulp, wormcast, cobalt blue pigments, microbial yeast, brewer's grains, table salt, lard oil, mint, 1-10mm ramie, 50% choline chloride, liquid vitamin C and a traditional Chinese medicine additive. The traditional Chinese medicine additive comprises the following raw materials: Chinese yarn, fresh ginger, isatis roots, endothelium corneum gigeriae galli, lysimachia christinae hance, chrysanthemum, honeysuckle, gallnuts, houttuynia cordata and oriental arborvitae. The fish feed disclosed by the invention has a same anti-disease effect on almost freshwater fishes, is balanced in nutrient and can be suitable for growing conditions of almost freshwater fishes; by adding the traditional Chinese medicine component additive, the fish feed improves the anti-disease ability of fishes, is safe and pollution-free and comprehensively increases the economical benefit of rice field cultivation; and in addition, the preparation method of the fish feed is simple, and large-scale production is conveniently realized.

Description

technical field [0001] The invention relates to the technical field of aquaculture feed, in particular to a paddy field fish feed and a preparation method thereof. Background technique [0002] Fish meat is tender and nutritious. It contains a large amount of protein and trace elements, vitamins, lecithin, etc. needed by the human body. The Qi-replenishing and health-preserving food is also the most important source of protein food for our people. [0003] In the prior art, in order to lower the cost of building fish farming ponds and expand the profit margin of fish farming, a large number of researchers have begun to establish fish farming as a three-dimensional farming method, which has attracted widespread attention; this year there are also A large number of successful reports of using rice fields to raise fish, such as only using the water surface of rice fields to raise fish, that is, simply using rice fields instead of ponds for original stocking; but due to the lac...

Problems solved by technology

[0003] In the prior art, in order to lower the cost of building fish farming ponds and expand the profit margin of fish farming, a large number of researchers have begun to establish fish farming as a three-dimensional farming method, which has attracted widespread attention; this year there are also A large number of successful reports of using rice fields to raise fish, such as only using the water surface of rice fields to raise fish, that is, simply using rice fields instead of ponds for original stocking; but due to the lack of scientific and reasonable management and feeding materials in this farming method, fish Poor survival rate and disease resistance, resulting in lower yield and even affecting fish meat quality

In addition, in rice field fish farming, multiple species of fish may be raised at one time. For example, grass carp, crucian carp, and bream are raised in the same rice field at the same time. These fish have different growth rates and disease resistance. The fish feed on the market is generally only a nutritious feed designed for a certain type of fish, so a certain fish grows faster, while other fish grow slower, and their disease resistance is also quite different. Once one fish gets sick, other fish will also be infected, which greatly reduces economic benefits

[0004] In order to improve the disease resistance of fish in rice field fish farming, feed manufacturers often add additives to fish feed to improve the disease resistance of rice field fish, but the current additives mostly use antibiotics, compounds, trace elements or hormones, etc., these Additives are easy to cause residues, and may cause cancer, deformity, and mutations. Humans will affect their health after eating them. Feed additives play an important role in freshwater aquaculture. Therefore, seeking efficient and harmless feed is the key to improving fish growth performance and key to disease resistance
