The invention relates to a technology for cultivating Yangtze river coiliaectenes fingerlings of the same year in a brackish water pond, which is characterized by comprising the following steps of: selecting a water pond in an estuary region, adding natural brackish water with a salinity of 5-15 percent, carrying out bait biological inoculation at a water temperature of 25-30 DEG C and putting the fingerlings after the biomass in the pond achieves 20-40 baits / L; carrying out salinity increasing transition before the fingerlings are put into the pond, so that a difference between the salinity of water in an indoor cement pond and the salinity of the water in the pond does not exceed 0.2 percent; turning on an aerator before the fingerlings are put into the pond and ensuring that the water temperature and the salinity in a fish fry oxygen bag are close to those in the pond when the fingerlings are put, the specification of each fingerling put is 5-7 cm in full length, and the stocking density is 1,500-20,000 fingerlings / mu; turning on the aerator in advance before opossum shrimps are inoculated, wherein the aerator is turned on for 1 hour at noon in a fine day and for 5-8 hours at night; replacing 1 / 3 of water semimonthly in summer and replacing 1 / 3 of water monthly in autumn; timely supplementing when the biological density is lower than 1 bait / L and catching at a water temperature of 6-8 DEG C in winter, wherein the weight of coiliaectenes is 2.5-3.5 g, and the full length is 10-12 cm.

The invention discloses a factory breeding method for Octopus variabilis. According to the method, females of Octopus are removed from a polyculture pond after parents of Octopus mate, thus mutual injuring of males and females of Octopus is prevented and the quantity of fertilized eggs is guaranteed; the females of Octopus and the fertilized eggs are separately cultured, thus the effect of the parents of Octopus upon the water environment is less and hatching rate influenced by frightening is avoided for the parents of Octopus. In addition, the young Octopus is traditionally considered to be fed only with opossum shrimps, adult Artemia, Monocorophium acherusicum and the like as initial feed, while, through long-term observations and experiments, the inventor finds that the young Octopus can also be initially fed with miscellaneous juvenile crabs lower than 0.1g in weight, and accordingly survival rate of the young Octopus can be increased. Therefore, the method having the advantages is especially suitable for popularization and application to the field and has very promising market prospect.

The invention relates to health care shrimp paste and a preparation method of the health care shrimp paste and belongs to the technical field of food processing. Health care shrimp paste is prepared from the following raw materials in parts by weight: 50-80 parts of opossum shrimp, 12-18 parts of table salt, 15-20 parts of colza oil, 5-8 parts of white sugar, 5-8 parts of sauce, 8-18 parts of liquor, 3-5 parts of ginger powder, 5-8 parts of fructus hippophae, 12-15 parts of wolfberry, 3-8 parts of fructus chaenomelis, 2-4 parts of rhodiola rosea, 1-3 parts of cuscuta chinensis, 1-5 parts of gorgon fruit, 2-5 parts of purslane, 2-4 parts of radix aucklandiae, 1-3 parts of myrobalan, 3-6 parts of astragalus mongholicus and 20-25 parts of white sesame seed. The health care shrimp paste has rich nutritive elements such as protein, calcium, ferrum, selenium and vitamin A; by addition of fruits rich in vitamin C and a part of traditional Chinese medicinal materials, synthesis of nitrite can be prevented; a nutrient content of the shrimp paste is increased; and the health care shrimp paste is suitable for people of all ages.
