Problems solved by technology

Sea bass sea cage culture often uses chilled fish as bait. Due to the limited source of fresh feed, the catch is obviously affected by the season, and it is easy to spoil and deteriorate. The uneaten chilled fish sinks to the bottom of the water, resulting in eutrophication of the water body. It has caused great damage to the fragile water environment, and sea bass often suffers from serious diseases. In recent years, artificial breeding of sea bass usually uses high-grade puffed materials as the staple food and uses a small amount of fish larvae. In order to improve the resistance of sea bass to diseases, The abuse of fish medicines has resulted in a decline in the quality of perch aquatic products and damage to the ecological balance of the water body, forming a vicious circle
Therefore, there is an urgent need for a perch feed that can improve the resistance of perch to diseases, and has solved the problems of the abuse of fish medicines, resulting in the decline of the quality of perch aquatic products and the destruction of the ecological balance of water bodies

Abstract

The invention provides a perch feed and a preparation method thereof. The perch feed comprises the following raw materials: a traditional Chinese medicine extract, wherein the traditional Chinese medicine extract comprises zaocys dhumnade. Zaocys dhumnade included in the traditional Chinese medicine extracts in the raw materials of the perch feed has good anti-inflammatory and analgesic effects; intermediate components such as various amino acids, fatty acids, trace elements and nucleosides are contained to different extents and have multiple functions of resisting bacteria, resisting oxidation, enhancing body immunity, reducing animal stress, regulating glycometabolism and the like so that the components have remarkable effects of improving the disease resistance of perches, increasing the survival rate, improving the fish quality, increasing the growth rate and the like after being added into perch feed.

Description

technical field [0001] The invention belongs to the technical field of fish feed, and in particular relates to a perch feed and a preparation method thereof. Background technique [0002] Perch is also known as flower perch, Zhaihua, perch board, seven-star perch, four-rib fish, etc., commonly known as perch, and belongs to Perciformes and Fataceae in taxonomy. Fish" one. The meat of self-bass is white and tender, fragrant, without fishy smell, and the meat is in the shape of garlic cloves. It is most suitable for steaming, braised in soy sauce or stewed soup. The fishing season is spring and autumn, and October-November is the peak fishing season, especially at the end of autumn and early winter. The mature perch is particularly plump, and the nutrients accumulated in the fish are also the most abundant, so it is the best to eat perch season. Perch likes to live in brackish and fresh water in estuaries, and can also live in fresh water. It is distributed in the western P...
