Problems solved by technology

[0010] 1. Strong limitations, such as live water boat transporting shrimp is only suitable for river network areas, where the river water environment is required to be free from pollution and the temperature is low
[0011] 2. The transportation cost of oxygenation in nylon bags is relatively high, which is only suitable for the transportation of shrimp seedlings, broodstock or juvenile shrimps, and is not suitable for large-scale transportation of finished shrimps on the market
[0013] In order to improve the survival rate of fresh shrimp during transportation, some people have studied the long-distance transportation after anesthetizing the live shrimp by soaking in ethanol solution. intended purpose

Abstract

The invention relates to a method for improving the survival rate of commodity shrimps of macrobrachium rosenbergii during long-distance transportation. The method comprises the following steps of: adding vitamin C into water for transportation in a transportation box and a spare box, wherein 50-100g of the vitamin C is correspondingly added in each ton of the water for transportation; regulating the pH of the water for transportation to 7.0-7.5, and controlling the water temperature of the water for transportation at 12-18 DEG C; and immersing a shrimp collection box in the water for transportation in the transportation box, transporting, using an oxygen increasing device to increase oxygen in the water for transportation during transportation, controlling the oxygen content in the water for transportation at 5-7mg / L, and draining sewage at the box bottom of the transportation box and supplementing spare water for transportation from the spare box to the transportation box every 2-3 hours after the start of the transportation. According to the method disclosed by the invention, the survival rate of the commodity shrimps of the macrobrachium rosenbergii during the long-distance transportation can be greatly improved, the method is simple and easy to operate, and the macrobrachium rosenbergii after the transportation according to the method is harmless to a human body after being taken by a person.

Description

technical field [0001] The invention belongs to the technical field of fish farming, and in particular relates to a method for improving the survival rate of Macrobrachium rosenbergii commercial shrimp in long-distance transportation. Background technique [0002] Giant river prawn (Macrobrachium rosenbergii) is the largest freshwater prawn in the world. In some natural waters in Southeast Asia, the male shrimp is 40cm long and weighs 600g, and the female shrimp is 25cm long and weighs 200g. At present, in my country's artificial breeding for 5 months, the male shrimp can reach 13.15cm in body length and about 80g in body weight, and the female shrimp's body length is 10-12cm in length and about 40g in weight. Macrobrachium rosenbergii grows fast and has high yield. When the stocking density is 90×10 per hectare 4 ~120×10 4 At the end of the day, after 5 months of artificial breeding, its yield per unit area could reach 7 000 kg / ha. Macrobrachium rosenbergii has a wide d...
