Problems solved by technology

At present, although there are mud crab compound feeds that are produced and sold according to the formula of river crabs and other crustaceans, due to insufficient research on the nutritional requirements of mud crabs, no compound feeds that are really suitable for mud crabs have been developed.

Embodiment 1

[0021] A method for preparing compound feed for three-dimensional cultivation of blue crabs in industrialized circulating water:

[0022] Take the production of diameter 3mm, length 6mm hard pellet feed 100kg for pseudo-cave blue crabs as an example. Fish meal 35kg, soybean meal 18kg, shrimp shell powder 7.5kg, corn starch 26kg, squid meal 2kg, choline 0.7kg, lecithin 2kg, cholesterol 0.8kg, carboxymethylcellulose sodium 1kg, sodium alginate 2kg, multivitamin 1kg of the premixture and 1kg of calcium dihydrogen phosphate are respectively pulverized with a pulverizer, passed through a 60-mesh sieve, weighed according to the stated ratio, and then placed in a feed mixer, adding 3kg of fish oil to gradually expand and stir evenly, using a 3mm granulating abrasive, extruding Pressed into 6mm long hard pellet feed. The prepared feed was dried in a constant temperature drying oven at 60°C for 18 hours, and stored in a refrigerator at 0°C.

Embodiment 2

[0025] A method for preparing compound feed for three-dimensional cultivation of blue crabs in industrialized circulating water:

[0026] Take the production of diameter 3mm, length 8mm hard pellet feed 100kg as an example. Fish meal 31kg, soybean meal 25kg, shrimp shell powder 7.5kg, corn starch 23kg, squid meal 2kg, choline 0.7kg, lecithin 2kg, cholesterol 0.8kg, carboxymethylcellulose sodium 1kg, sodium alginate 2kg, multivitamin 1kg of the premixture and 1kg of calcium dihydrogen phosphate are respectively pulverized with a pulverizer, passed through a 100-mesh sieve, weighed according to the stated ratio, and placed in a feed mixer, adding 3kg of fish oil to gradually expand and evenly stir, using a 3mm granulating abrasive tool, extruding Pressed into 8mm long hard pellet feed. The prepared feed was dried at 60°C for 18 hours and stored in a refrigerator at 0°C.

Abstract

The invention discloses a compounded feed for factory circulating-water three-dimensional culture of scylla paramamosain and belongs to the technical field of aquaculture. The feed for the scylla paramamosain, disclosed by the invention, contains the following raw materials in parts by weight: 250-350 parts of fish meal, 150-250 parts of soybean meal, 50-100 parts of shrimp shell meal, 200-300 parts of corn starch, 20-30 parts of squid meal, 20-30 parts of fish oil, 5-10 parts of choline, 10-20 parts of lecithin, 5-10 parts of cholesterol, 5-10 parts of sodium carboxymethyl cellulose, 10-20 parts of sodium alginate, 10-20 parts of multi-dimensional multi-mineral premix and 5-10 parts of calcium dihydrogen phosphate. According to the feed disclosed by the invention, the formula is scientific and reasonable, the preparation method is simple, convenient and quick, the processing cost is low, the performance is good, the food calling performance is high, the growth and shelling of the scylla paramamosain can be effectively promoted, the survival rate is increased, and the pollution to environments caused by culture excrements is alleviated.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a compound feed for three-dimensional cultivation of blue crabs in industrialized circulating water. Background technique [0002] Pseudomonas blue crab, commonly known as sturgeon, has the characteristics of wide diet, fast growth, strong adaptability and disease resistance, long drying time, and easy transportation. It is an excellent species for artificial breeding. In recent years, mud crab farming has flourished in the eastern coastal areas and southern provinces of China, with an annual output of about 15.19×10 4 t. Among them, the annual output of Guangdong Province is about 5.50×10 4 t, ranking first in the country, the annual output of Fujian Province is about 3.51 ×10 4 t, ranking second in the country (China Fishery Statistical Yearbook, 2018). In the past, it was believed that there was only one species of Scylla serrata in China, but later it was...
