A method for long-distance transportation of fresh and live cold-water fish

Abstract

The invention relates to a long-distance transport method for fresh cold water fishes. The long-distance transport method is characterized by comprising the following steps of putting the cold water fishes in a fish bag filled with water which is 1 / 5-1 / 4 of the weight of the fishes; fully inflating the fish bag with oxygen, and then, sealing; keeping the fish bag water-tight and air-tight; putting the fish bag in a transport case, and putting 1-2 ice bags in the transport case so as to enable the water temperature in the fish bag to be kept to be 0-18 DEG C during a whole transport process. The fish bag is made of a water-tight and air-tight soft material; the water used in the fish bag is clean spring water or clean river water of which the water temperature is 0-18 DEG C. The long-distance transport method for the fresh cold water fishes provided by the invention is suitable for keep-alive transport of the cold water fishes, such as Chinese sturgeon, Polyodonspathala, salmon, rainbow trout, golden trout, giant salamander (megalobatrachus) and the like, and also suitable for the keep-alive transport of other non-cold water fishes.

Description

technical field [0001] The invention relates to a method for long-distance transportation of fresh and live cold-water fish. Background technique [0002] Cold-water fish is a type of fish. It has high requirements for the living environment, especially the water temperature. If the water temperature is higher than 20 degrees, it cannot survive, so it is called cold-water fish. Common species of cold-water fish include salmon, golden trout, rainbow trout, sturgeon, squid, spotted cucumber fish (stone fish), naked cucumber fish (stone fish), silver croaker (yellow croaker), Ili hip scale fish (big head), Baikal pike (small white strip), black-spotted loach (pike), black-backed pike (pike), jelly salmon, northern pike, yarrow, wudaohei, black fish, pike perch, Eastern European Bream, gibel crucian carp, willow root fish, Huazi fish, etc. [0003] The breeds of cold-water fish are salmon trout and sturgeon. Their original living environments are mountain streams and rivers re...

For this reason, the market prospects of artificially farmed salmon and trout are good, and the supply of products is in short supply. However, due to the influence of natural environments such as climate and water quality, the scale of farming in my country cannot meet the needs of consumers. Taking salmon as an example, more than 2 / 3 of the demand import

[0008] Cold-water fish not only has high requirements on the natural environment for breeding, but also has great difficulties in long-distance transportation of live fish. If it is higher than 18°C, it will die quickly, the meat will rot, lose its commercial value, and even be inedible. For this reason, some Aquaculture companies have tried their best, such as adding short-term preservatives, salt or sea crystals to the water, but they can only keep the Chinese sturgeon alive for 13 hours during transportation, and the fry can only keep alive for about 38 hours.
