Method for keeping large number of freshwater fishes alive without water

Abstract

The invention discloses a method for keeping a large number of freshwater fishes alive without water. The method comprises the simple steps that bream are temporarily kept for 1-9 d in a fasting mode before keeping alive without water, water temperature is reduced to 0 DEG C to 8 DEG C from 10 DEG C to 20 DEG C at the speed of 0 DEG C / h to 10 DEG C / h before the bream are kept alive without water, and the bream are temporarily kept for 0-8 h at the temperature of 0 DEG C to 8 DEG C; the bream are put in a foam box with wood bits, the 10-20 bream are placed in the foam box with pelvic fins above dorsal fins, the bream are completely covered with the wood bits, the adopted wood bits need to be soaked in water of 0 DEG C to 10 DEG C for 0-8 h, and then water drainage is carried out for 0-2 h; then the foam box is sealed after being packaged with common PE bags and inflated with oxygen, the bream are kept alive at the temperature of 0 DEG C to 6 DEG C, the bream are moved to the water environment of 4 DEG C to 15 DEG C for 0-5 h after being kept alive without water, then the bream are moved to the water temperature of 10 DEG C to 20 DEG C, and the bream are restored to a normal state. The method is safe, efficient, high in survival rate and capable of being applied to transporting living bodies of aquatic products, transportation cost is greatly reduced, and the health condition of the aquatic products is not influenced.

Description

technical field [0001] The invention relates to the field of keeping alive aquatic products, in particular to a method for keeping alive aquatic products without water, especially a method for keeping alive bream without water. Background technique [0002] The bulk of freshwater fish refers to herring, grass carp, silver carp, bighead carp, carp, crucian carp and bream. As a high-protein, low-fat, nutritious food, they are one of the main sources of protein in the food composition of our people. Moreover, people only agree with live fish when they buy large quantities of freshwater fish, and their economic value basically loses after the fish dies. Due to the large geographical span of production and sales, immature preservation technology and imperfect transportation equipment configuration, etc., the transportation cost of aquatic products is high, and the loss rate of long-distance transportation is high (more than 10%), which greatly restricts the development of the fre...

Problems solved by technology

Due to the large geographical span of production and sales, immature preservation technology and imperfect transportation equipment configuration, etc., the transportation cost of aquatic products is high, and the loss rate of long-distance transportation is high (over 10%), which greatly restricts the development of the freshwater fish sales market.
