Embodiment 2

[0046] Adopt the equipment of the present invention to transport the live body of irritable fish and transport the survival rate. During the transportation, the following control methods are adopted for water temperature, water flow, oxygen, light, water quality and salinity:

[0047] (1) Water temperature management: put the DC temperature control heating rod into the air lift pump pipe, turn on the heating rod when heating is required; add ice cubes to the upper layer of the filter bucket when the temperature needs to be lowered, and the ice water passes through the filter and is pumped by the air lift pump Flow into the box; before transportation, store the ice cubes in the foam box, put the ice cubes into the ice cube layer 4 when the temperature needs to be lowered, and control the water temperature within an appropriate range. Never add ice cubes directly to the transport fish box. In order not to cause scratches on the ice, or the local cooling of the ice will cause disc...

Abstract

The invention provides equipment for improving the live transportation survival rate of edgy fishes. The equipment comprises a tank (1), a plastic cover film (2) matched with the tank (1), and a water purifier (3). The water purifier (3) comprises a water distribution layer (4), an ice cube layer (5), a filter cotton layer (6), an active carbon layer (7), and a water storage layer (8), wherein the above layers are arranged from top to bottom. The lower part of the tank (1) is provided with a water inlet pipe (9) to be connected with the water distribution layer (4) via the water purifier. The upper part of the tank (1) is provided with a provided with a water outlet pipe (10) to be connected with the water storage layer (8) via the water purifier. The water outlet pipe (10) of the water purifier is provided with an airlift pump interface (11). According to the technical scheme of the invention, a water quality purification method for water in transportation facilities is provided for aquaculture practitioners during the transportation process based on the physiological characteristics of saury and shad. In this way, the collision injured risk of fishes when frightened is reduced, and the water quality of the transportation water is improved. Meanwhile, the metabolites of fishes are timely eliminated, so that the stress reactions of edgy fishes, such as saury and shad, are reduced. Moreover, the risk of mechanical traumas and the risk of physiological endogenous injuries during the transportation process are reduced. The live transportation survival rate of fishes is improved. Furthermore, the temporary-rearing or cultivation survival rate of fishes after the transportation process is improved.

Description

technical field [0001] The invention belongs to the field of breeding, and in particular relates to a device for improving the survival rate of irritable fish live transportation, and also relates to a method for improving the survival rate of irritable fish live transportation. Background technique [0002] Live transport of fast-tempered fish such as knifefish (Coiliaectenes) and American shad (Alosasapidissima) has long been a challenge for the aquaculture industry. On the one hand, both saury and shad are migratory fish, whose important behavioral and physiological characteristics are endless swimming, frightened irritability and poor tolerance to sewage. However, saury and shad are delicate and impatient. Entering a small water body transport container, the reaction is violent, swimming rapidly, sometimes colliding with the container wall, causing trauma, and even death immediately; on the other hand, because shad and saury have extremely strict requirements on water qu...
