Problems solved by technology

However, along with the expansion of aquaculture area and the improvement of aquaculture output, phenomena such as high morbidity rate, small market size and low commodity rate of prawns have occurred, which have affected the benefits of farmers, and most of the nutrients in the feed are not very reasonable. Not only Affect the environment, and the survival rate and quality of the shrimp have not been significantly improved

Embodiment 1

[0019] A method for cultivating basal shrimp rich in DHA, wherein the basal shrimp is fed with a feed formulated with the following raw materials in parts by weight: 25 parts of peanut powder, 15 parts of soybean meal, 5 parts of earthworm powder, 5 parts of schizochytrium fungus powder, and 5 parts of schizotroph 15 parts of bacteria waste residue, 3 parts of Bacillus natto, 0.4 part of yeast extract, 15 parts of corn germ oil, and 3 parts of Houttuynia cordata extract;

[0020] The preparation method of the feed comprises the following steps: 1) mixing peanut powder and soybean meal according to parts by weight and performing primary crushing and superfine crushing, so that the fineness of the raw materials reaches 500 meshes, and is ready for use; After mixing and pulverizing the bacteria powder and Schizochytrium waste residue, add Bacillus natto, yeast extract and water, mix and ferment for 8 hours; 3) Mix the materials treated in steps 1) and 2) evenly, then add corn germ...

Embodiment 2

[0022] A method for cultivating shrimps rich in DHA, the same as in Example 1, the difference is that the preparation method of the feed comprises the following steps: 1) mixing peanut powder and soybean meal by weight and performing primary grinding and superfine grinding, Make the fineness of the raw material reach 300 meshes, and wait for use; 2) After mixing and pulverizing the Schizochytrium powder and the Schizochytrium waste residue by weight, add Bacillus natto, yeast extract and water and mix and ferment for 10 hours; 3 ) Mix the materials treated in steps 1) and 2) evenly, add corn germ oil and water, mix well, and then granulate; 4) Dry the granulated feed granules in step 3) at 100°C, and the fish The extract of Houttuynia cordata is uniformly sprayed on the surface of the feed granules; (5) the grading sieve is used to remove the powder, and the qualified packaging is inspected. Step 2) Fermentation conditions: temperature 25° C., shaker fermentation at 500 r / min....

Embodiment 3

[0024] A method for cultivating shrimps rich in DHA, the same as in Example 1, the difference is that the preparation method of the feed comprises the following steps: 1) mixing peanut powder and soybean meal by weight and performing primary grinding and superfine grinding, Make the raw material fineness reach 450 meshes, stand-by; 2) After mixing and pulverizing the Schizochytrium powder and the Schizochytrium waste residue by weight, add Bacillus natto, yeast extract and water and mix and ferment for 5 hours; 3 ) Mix the materials treated in steps 1) and 2) evenly, add corn germ oil and water, mix well, and then granulate; 4) Dry the granulated feed granules in step 3) at 80°C, and the fish The Herba Houttuyniae extract is evenly sprayed onto the surface of the feed granules; (5) the grading sieve is used to remove the powder, and the qualified packaging is inspected. Step 2) Fermentation conditions: temperature 32° C., shaker fermentation at 300 r / min.

Abstract

The invention discloses a culture method for DHA-rich Metapenaeus ensis. The Metapenaeus ensis is fed with a feedstuff prepared from the following raw materials in parts by weight: 20-30 parts of peanut powder, 10-25 parts of bean pulp, 2-5 parts of earthworm powder, 0-10 parts of Schizochytrium limacinum powder, 10-25 parts of Schizochytrium limacinum waste residue, 1-5 parts of Bacillus natto, 0.2-0.5 part of yeast extract, 10-25 parts of maize germ oil and 1-5 parts of herba houttuyniae extracting solution. The culture method disclosed by the invention is low in cost, safe and reliable, and causes no pollution; the Metapenaeus ensis is fed with the feedstuff using the Schizochytrium limacinum and the waste residue thereof as the raw materials, thereby increasing the DHA and EPA contents in the prawn meat, enhancing the immunity of the Metapenaeus ensis, and promoting the growth and development of the Metapenaeus ensis. The culture method is applicable to large-scale culture of DHA-rich safe and functional Metapenaeus ensis products.

Description

technical field [0001] The invention belongs to the field of basilisk shrimp cultivation, and in particular relates to a cultivation method of basophila prawns rich in DHA. Background technique [0002] Modern food nutrition research shows that the content of polyunsaturated fatty acids in the diet is closely related to the health of the human body, and the role of n-3 polyunsaturated fatty acids is particularly prominent. Increase the intake of n-3 polyunsaturated fatty acids in the diet It helps to maintain the physiological functions of cells, reduce blood lipids and cholesterol levels in blood, reduce blood viscosity, increase the activity of brain cells, thereby reducing the incidence of cardiovascular and cerebrovascular diseases. In particular, EPA and DHA in n-3 polyunsaturated fatty acids have important physiological effects on the human body. EPA has good functional effects on promoting the metabolism of saturated fatty acids in the body, preventing fat deposition...
