Special-purpose feed for juvenile fishes of Matsue perches, and preparation method thereof

Abstract

The invention discloses a special-purpose feed for juvenile fishes of Matsue perches. The feed is prepared from the following components in parts by weight: 50-70 parts of clams, 10-15 parts of fish meal, 20-30 parts of sesame seed meal, 5-10 parts of purslane, 5-10 parts of garlic, 6-12 parts of wild chrysanthemums, 2-4 parts of pomegranate rind, 3-5 parts of Chinese scholartree leaves, 8-16 parts of Chinese dates, 1-5 parts of pomelo peel, and 4-8 parts of onions. The preparation technology is simple and the operability is high. The content of crude proteins in the feed can be increased through fermentation treatment, the traditional Chinese medicine plants are added, so that the feed can play the action of disease and pest resistance, and virus resistance, and the feed has the effects of preventing and treating dermatomycosis, bacterial gill-rot diseases and the like. The Chinese dates are added in the feed, so that the immunity of the juvenile fishes is convenient to improve; the pomelo peel and the onions, which are added, can effectively improve the tastiness of the feed. The particle feed disclosed by the invention has the advantages that the stability of the feed in water is good, breed water is not easy to pollute, the survival rate of the juvenile fishes of the Matsue perches is increased, the feed coefficient is reduced, and the feed conversion rate is increased.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a special feed for juvenile Songjiang perch and a preparation method thereof. Background technique [0002] Songjiang perch is also called four-gill perch, flower drum fish, etc. The adult fish has a body length of 5-17cm, a long spindle-shaped body, a flat front, a nearly cylindrical rear, and gradually becomes smaller and sharper in the rear, with a large, wide and flat head. , the head and face are covered with skin. Songjiang perch is widely distributed in fresh water and shallow seas in my country. It is distributed in the Bohai Sea, the East China Sea, the Yellow Sea coast and the rivers and lakes connected to the sea. However, the Yangtze River Delta is the main distribution area. It has the habit of reproductive migration and lays eggs every autumn and winter. It enters the sea from fresh water at the end of November, and ends in early February of the following ...

Problems solved by technology

[0003]In recent years, due to the development of water conservancy construction, rivers and lakes have been isolated, causing Songjiang perch to lose a place to grow and develop. The impact of environmental pollution caused by the widespread use of pesticides and chemical fertilizers has severely depleted the natural resources of Songjiang perch, and the market is in short supply, prompting the rapid development of artificial breeding of Songjiang perch. At present, the cultivation of juvenile Songjiang perch is very important. It is related to the various body properties of adult fish. During the breeding process, juvenile fish are mostly fed fresh and live bait, such as small fish and shrimp, etc. Fresh and live bait has problems of high cost and low utilization rate, and it is easy to pollute water quality. Caused many diseases of Songjiang perch, resulting in low survival rate of juvenile fish, but the current research on Songjiang perch is mostly focused on the breeding technology of broodstock, and there is very little research on the feed of Songjiang perch
