Embodiment 1

[0032] A spray agent for long-distance transportation of crayfish. The components and contents in 500g spray agent are: 0.02g vitamin A, 0.50g vitamin E, 15.00g glucose, 120.00g potassium chloride, 50.00g corn α-starch, salt 314.48 g. The content of vitamin A used was 600,000 IU / g. The content of vitamin E used was 500 IU / g. Corn α-starch and glucose are both 99% pure. Salt and potassium chloride need to be finely crushed and passed through a 80-mesh sieve.

[0033] The spray preparation method is as follows:

[0034] (1) earlier, salt and potassium chloride were pulverized respectively, sieved, and then the raw materials were weighed according to the weight ratio, and set aside;

[0035] (2) Stir and mix the weighed salt, potassium chloride, and corn α-starch evenly; then add vitamin A and vitamin E, and mix well;

[0036] (3) Finally, add glucose and mix evenly to obtain a spray agent.

Embodiment 2

[0044] A spray agent for long-distance transportation of crayfish. The components and contents in 500g spray agent are: 0.03g vitamin A, 1.00g vitamin E, 20.00g glucose, 130.00g potassium chloride, 70.00g corn α-starch, salt 278.97g. The content of vitamin A used was 600,000 IU / g. The content of vitamin E used was 500 IU / g. Corn α-starch and glucose are both 99% pure. Salt and potassium chloride need to be finely crushed and passed through a 90-mesh sieve.

[0045] The spray preparation method is as follows:

[0046] (1) earlier, salt and potassium chloride were pulverized respectively, sieved, and then the raw materials were weighed according to the weight ratio, and set aside;

Embodiment 3

[0057] A spray agent for long-distance transportation of crayfish. The components and contents of 500g spray agent are: 0.03g vitamin A, 0.75g vitamin E, 17.00g glucose, 125.00g potassium chloride, 60.00g corn α-starch, salt 297.22g. The content of vitamin A used was 600,000 IU / g. The content of vitamin E used was 500 IU / g. Corn α-starch and glucose are both 99% pure. Salt and potassium chloride need to be finely crushed and passed through a 80-mesh sieve.

Abstract

The invention discloses a method for long-distance transportation of crayfish, which belongs to the technical field of modern fishery. The method for long-distance transportation of crayfish of the present invention comprises the following steps: (1) crayfish in a farm, select a strong, uninjured crayfish and put them into a shrimp cage for temporary cultivation, stop eating for more than 24 hours; (2) use a basket For crayfish, each basket contains 7-10kg crayfish, and the bottom of the basket is covered with aquatic plants in advance. The thickness of the aquatic plants is 0.1-1.0cm. Every 10 baskets are stacked into a stack, and a layer of moist aquatic plants is covered on the top basket; (3) the basket Transfer to the transport box and use the air conditioner to control the temperature at 14-15°C. The transportation method of the present invention cooperates with the use of the spraying agent, and at the same time is supplemented by the correct cooling and temperature control method, so that the survival rate of the crayfish can reach more than 90% within the transportation time of 30 hours, and the survival rate of the crayfish can reach more than 90% within the transportation time of 20 hours. Within 1 week, the survival rate of transportation can reach more than 95%, and there is basically no stress death within 1 week after being sent to the pond.

Description

technical field [0001] The invention belongs to the technical field of modern fishery, and in particular relates to a method for long-distance transportation of crayfish. Background technique [0002] Procambarus clarkii, commonly known as crayfish, has seen increasing consumption in recent years, rising market prices, and expanding breeding areas. It has gradually expanded from the original main producing areas of Hubei, Jiangsu, and Jiangxi to Guangxi, Guizhou, and Yunnan. At present, the broodstock and seedlings used in Guangxi are mainly imported from Hubei, Jiangsu and other places. They are usually transported dry with cooling and leaving water, and the transport time ranges from 20 to 30 hours. [0003] At present, the use of humidified low-temperature refrigerated vehicles for transportation can basically guarantee a survival rate of more than 95% when the quality of broodstock and seedlings is normal, but the transportation cost is relatively high. Therefore, the m...
