Fresh-keeping material for crabs and usage method thereof

Abstract

The invention discloses a fresh-keeping material for crabs and a usage method thereof. The fresh-keeping material for crabs comprises the following components in parts by weight: 3-8 parts of sodium chloride, 8-20 parts of opal, 14-26 parts of tourmalinite, 13-20 parts of vermiculite, 9-18 parts of algae, 15-25 parts of Epipremnum aureum, 2-9 parts of lotus leaves and 2-7 parts of pine needles. The fresh-keeping material for crabs can generate negative ions and oxygen, and provides a good living environment for crabs; the structure with multilayer arrangement can effectively avoid mutual squeezing and compressing of crabs, avoid consumption of oxygen and physical power due to creeping of crabs, and increase survival rate of crabs in transport process.

Description

technical field

[0001] The invention relates to a fresh-keeping material for crabs used in the technical field of fresh-keeping and a method for using the same. Background technique

[0002] Crab meat is delicious and nutritious, and has been generally recognized as one of the delicacies at home and abroad. The market demand for crabs is increasing year by year, but during the transportation of crabs, due to improper means and methods of transportation, it is easy to cause a large number of crabs to die during transportation, which brings economic losses to farmers. Traditional fresh-keeping methods use air-permeable straw bags, air-permeable cartons, or water-filled containers. These fresh-keeping methods will still accumulate crabs, and the crabs can crawl freely, increasing the consumption of oxygen and physical strength, which not only increases transportation costs, but also may lead to obesity. further death.
