High-density fish keep-alive transportation box and transportation method

Abstract

The invention relates to the field of fish keep-alive transportation, and specifically relates to a high-density fish keep-alive transportation box and a specific transportation method for transporting live fishes through the transportation box. The transportation box comprises a transportation box body and a transportation box cover, and the transportation box body is divided into a fish transportation area and a transportation water circulation area; the transportation box cover and the transportation box body of the live fish transportation area are connected through a rotating shaft, a splash-proof exhaust hole is formed in the transportation box cover, and sealant is arranged at the joint of the transportation box cover and the transportation box body; the transportation water circulation area is arranged on the right side of the inner side of the transportation box body and specifically comprises a water quality purification system, a refrigerating machine and an aeration system; and the water quality purification system is composed of a primary filtration area, a secondary filtration area, an activated carbon filtration area and an ultraviolet sterilization area. According to the technical scheme, water quality deterioration can be effectively delayed, and the live fish transportation survival rate is increased.

Description

technical field [0001] The invention relates to the field of fish preservation transportation, in particular to a transportation box and transportation method which delay the deterioration of transportation water quality and are suitable for high-density long-distance transportation of fish. Background technique [0002] At present, the long-distance transportation of fish generally adopts the following method: put the fish into a PE bag filled with a certain volume of water, then flush the oxygen into the water body, tie the PE bag tightly, and finally place it in a container filled with ice cubes. Transport in foam boxes or incubators. [0003] However, this mode of transportation has the following disadvantages: first, the direct contact between the ice cubes and the fish is easy to cause injuries, and the ice cubes are easy to melt, and the cold storage time is short, which will increase the mortality of fish after the temperature rises; second, keep alive transportation...

Problems solved by technology

[0003] However, this mode of transportation has the following disadvantages: first, the direct contact between the ice cubes and the fish is easy to cause injuries, and the ice cubes are easy to melt, and the cold storage time is short, which will increase the mortality of fish after the temperature rises; second, keep alive transportation With the consumption of oxygen by fish, the oxygen-filled packaging cannot maintain the dissolved oxygen level in the water for a long time, which may easily lead to the death of fish due to hypoxia; third, the oxygen-filled packaging cannot perform water circulation and filtration, which accelerates the deterioration of water quality. The accumulation of toxic and harmful substances in the water body (such as the increase in the level of substances such as ammonia nitrogen and nitrite; the acidic water quality caused by the decrease in pH value, etc.;) can easily lead to fish poisoning and death
