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.

Provided is a micro-oxygenating long-distance transport method for indoor breeding of seedlings of coilia ectenes. The method is characterized in that from the mid-term of July to the mid-term of August each year, seedlings of coilia ectenes undergoing artificial breeding grow to 3-5 cm; a dragging net for fries cultured in an indoor cement pool for all kinds of breeding fields; one day before seedlings of coilia ectenes are dragged into the net and transported, seedlings take exercises by net dragging for 2-3 times; seedlings stop eating for 12 hours before transport; fries are counted in a water bucket with the volume of 10 liters; each bucket contains 50-100 fish fries which are then transferred to a transport water tank; the transport water tanks are inflated with air by oxygen bottles with pure oxygen nanotubes; after fish tries arrive at the destination, water temperature of the fish pond and water temperature of the water tanks are detected; after fish tries in the water tanks are stabilized for 10-15 minutes, a spoon with the 1L volume is utilized for scooping up fish fries to the water tanks with the volumes of 10 L; and each water tank can hold 30-50 fish fries and fish fries are taken to the fish pond with water.

The invention discloses a rhinogobio ventralis parent fish transporting method. The method includes: cultivating individual rhinogobio ventralis parent fish for 15 days, and stopping feeding the parent fish for 2 days before transportation; sleeving two plastic bags together to form a double-layer packing bag; using anesthetic and clear Yangtze River water to prepare packing water at the final concentration of 25ppm; placing the fish into the inner bag filled with the packing water, and allowing the inner bag with the fish to be filled with oxygen; horizontally placing the tied packing bag in an unbroken foam box; placing ice blocks in the foam box and sealing the foam box with tape; controlling the time from packing bag tying to arriving to destination to be within 24 hours; opening the packing bag to place the fish in cultivating water so as to awaken the fish, and sterilizing in the cultivating water with salt to complete the whole transporting process. The method has the advantages stress reaction of the rhinogobio ventralis parent fish during transportation is reduced, fish body damage is avoided, and transportation survival rate is increased.

The invention discloses a method for controlling temporary breeding and packing prepared for aquatic product transportation. According to the method, when fishes are put into a temporary breeding tank, the water temperature of the temporary breeding tank is controlled to be between 8 and 25 DEG C, and the temporary breeding time of the fishes in the temporary breeding tank is 20 to 30 hours; during temporary breeding, after the fishes are put into the temporary breeding tank for 4 hours, the water temperature is reduced for 0.15 to 0.3 DEG C each hour, and when the water temperature is reduced for 2 to 2.5 DEG C, the water temperature is kept unchanged; in the temporary breeding tank, the water is replaced continuously in a circular mode, the salinity of the water in the temporary breeding tank is 0.1 to 0.5 percent, the PH value of the water quality is 5 to 8, the ammonia nitrogen content in the water is less than 0.6 milligram / liter, and the nitrite content in the water is less than 0.2 milligram / liter; and during packing, the water temperature in a packing box is controlled to be between 4 and 19.5 DEG C, the salinity of the water in the packing box is 0.1 to 0.5 percent, the PH value of the water quality is 5 to 8, the ammonia nitrogen content in the water is less than 0.6 milligram / liter, the nitrite content in the water is less than 0.2 milligram / liter, and the dissolved oxygen in the water is more than 3 milligram / liter. Compared with the prior art, by the method, the transportation survival rate can be improved, and the viability of aquatic products is improved, so that the freshness and deliciousness of meat is kept.

The invention relates to a live saury storage and transportation device and a storage and transportation method thereof, relating to a device capable of long-distance transportation of a live saury and a storage and transportation method of the device. A living saury storage and transportation device has a circular storage and transportation barrel, and the inner wall of the storage and transportation barrel has a flexible buffer layer to prevent the saury from hitting the inner wall with its head under emergency conditions, causing injuries to the head and internal organs, and due to storage and transportation The barrel is round. Compared with rectangles or polygons, it has no corners, so that the saury will not gather at the corners during swimming, causing extrusion between multiple saury, thereby increasing stress; storage and transportation barrels The outer wall of the tank is covered with a sound-insulating layer to reduce external noise from being transmitted into the storage barrel and prevent the saury from being stressed. There is a lid on the top of the storage barrel, which is made of non-transparent material. During the process of transporting the saury, it is necessary to use the lid to buckle the storage barrel to reduce the impact of light on the saury; the lid is threaded or buckled. The storage barrel is tightly fixed.
