[0003] Spotted grouper (Epinephelus coioids) is commonly known as "green spot" in Fujian, Guangdong, Taiwan and other places. Due to its good meat quality, fast growth, and easy transportation of live animals, it has become an important new species of mariculture in the southeast coast of my country in recent years. , but there are no relevant reports on the nutritional needs of grouper in China, and there is no special feed for grouper. Nutritional diseases occur from time to time, and if things go on like this, the culture of spotted grouper will inevitably develop towards an unhealthy state

Embodiment 1
[0021] Embodiment 1: This special feed for grouper includes nutrients such as protein, lipid, sugar, vitamins and minerals.
[0022] Among them, 56% protein, 8% sugar, 10% lipid, 0.5% vitamin, 4% mineral, and 1% binder. The specific formula is as follows:
[0027] The preparation method of special feed for grouper comprises the following steps:
[0028] 1) Material preparation: Prepare various feed materials and premixes according to the above formula ingredients and ratios, and choose dry materials with normal smell and color as much as possible. If the feed material is wet, it needs to be dried to a certain extent. After a period of storage of trace materials with strong water absorption in the premix, such as CuSO 4 , ZnSO 4 , FeSO 4 Wait to be dried.
[0029] 2) ...
example 2
[0034] Use example 2: Tianjin Lida Seawater Resources Co., Ltd. raises grouper with premix of the present invention, and simultaneously with other seawater fish feed as contrast, puts 45 seedlings per cubic meter, through 121 days of cultivation, every The output per cubic meter was 32.20 kg, and the feed coefficient was 1.47; the output of the control group was 27.40 kg / m3, and the feed coefficient was 1.90. The yield increased by 4.80 kg per cubic meter (14.91% increase rate), and the feed coefficient decreased by 0.43 (29.3%).

Abstract
The invention relates to a special feedstuff for E.malabaricus, which comprises nutritive substances such as protein, lipid, saccharide, vitamin, mineral, and the like, wherein the protein is between 52 and 56 percent, the saccharide is between 10 and 14 percent, the vitamin is 0.5 percent, the mineral is 4 percent, and an adhesive is 1 percent. The formulation specifically comprises the following components: 55 percent of fish meal, 10 percent of bean pulp, 4 percent of shrimp skin, 4 percent of yeast, 10 percent of casein, 2.68 percent of fish oil, 1.32 percent of bean oil, 6.5 percent of starch, 1 percent of choline, 0.5 percent of vitamin B complex, 4 percent of complex mineral, and 1 percent of algin. The special feedstuff determines the mixture ratios of the raw materials and the content of a few kinds of nutritive materials of various feedstuffs suitable for the growth of the E.malabaricus, and a method for processing and preparing the feedstuff, thus the special feedstuff is applicable to breeding the E.malabaricus in an industrial breeding mode. The special feedstuff is developed on the basis of studying the nutrition physiology of the E.malabaricus by referencing to the nutrient content contained in muscle and using the relative weight increase rate as a constant index. The special feedstuff can improve the yield of the E.malabaricus in a cubic water body by about 15 percent, reduce the bait coefficient to less than 1.5, and improve the utilization rate of baits.
Description
technical field [0001] The invention relates to the formula and simple processing of special feed for grouper, starting from the main nutritional components and nutritional physiological characteristics in the muscle of grouper, and relates to a feed formula suitable for its growth and development, grouper The special feed formula includes protein, fat, and crude fiber. The raw materials used include fish meal, soybean meal, shrimp skin, starch, peptone, etc. This feed formula can be applied to the factory farming model. Background technique [0002] Grouper is a general term for fishes of the order Perciformes, Percoidei, Serranidae, and Epinephelus. The common ones are Epinephelus akaara, bluestone Grouper (E.awoara), grouper (E.malabaricus), giant grouper (E.tauvina), salmon grouper (E.fario), cloud grouper (E.moara), Seven-banded grouper (E.septemfasciatus), salmon-shaped grouper (E.salmonoides), brown-spotted grouper (E.fuscoguttatus), small-toothed grouper (E.microdon...
