Problems solved by technology

The advantage of water truck oxygenation transportation is that the freight is relatively low, the oxygenation is sufficient, and it is convenient to observe the situation of fish at any time, but this method has great limitations
In the case of a small amount of live fish transported, the amount of water added and oxygenated by the water truck is basically the same as when transporting live fish in large quantities, and the cost cannot be reduced
In the case of a large demand for live fish, it cannot be guaranteed that the spotted trout will not suffocate due to lack of oxygen due to excessive density during transportation, resulting in low survival rate and affecting economic benefits

Embodiment 1

[0044] On a certain day in May 2014, the method of the present invention was used to transport 300 speckled trout with a specification of about 3 kg from the breeding base of the Breeding Research Center of Shandong Marine Biological Research Institute to Yantai, which lasted 4 hours. After arriving at the destination, 297 spotted trout survived and 3 died, with a survival rate of 99%. The specific steps are as follows:

[0045] 1. Stop eating spotted trout for transportation for 2 to 3 days.

[0046] Fill a reservoir of 5m×6m×0.4m with aquaculture water cooled to 2°C, leave floating ice on the water surface to keep the water temperature from rising, and use an air pump to increase oxygen to 10mg / L of dissolved oxygen in the water. Add 25mg / L eugenol to the water and stir well. Put the stopped and weighed spotted trout into a mixed water of ice and water containing eugenol. The fish is quickly cooled and anesthetized in the low temperature water mixed with eugenol. The cooling and...

Embodiment 2

[0050] On a certain day in April 2015, the method of the present invention was used to transport 50 speckled trout with a specification of about 4 kg from the breeding base of the Breeding Research Center of Shandong Marine Biology Research Institute to Jiaonan, which lasted 3.5 hours. After arriving at the destination, 50 spotted trout survived, 0 died, and the survival rate was 100%. The specific steps are as follows:

[0051] 1. Prepare a plastic foam incubator for transportation. The specifications are length: width: 58cm×45cm×15cm, bottom thickness 2.5cm, and wall thickness 2.0cm.

[0052] The packing bag is a double-layer plastic bag for transportation, the specification is length: width 65cm×45cm.

[0053] 2. Stop eating the speckled trout for transportation for 2 to 3 days.

[0054] 3. Fill a 1m×1m×2m reservoir with water for breeding that is cooled to 2°C, leave floating ice on the water surface to keep the water temperature from rising, and use an air pump to increase oxygen...

Abstract

The invention provides a hypothermic anesthesia transportation method for live Oncorhynchus mykiss, the method comprising following steps: 1) feed deprivation: food provisioning for Oncorhynchus mykiss is stopped for 2-3 days before transportation; 2) cooling and anesthesia treatment: water tanks are filled with cooled aquaculture water of 1-2 DEG C; the water temperature is maintained; anesthetic is added to the water and mixed well. The Oncorhynchus mykiss deprived of food is weighed and then put in the aquaculture water and quick cooling and anesthesia are performed. The Oncorhynchus mykiss is taken out of water surface when the activity ability of the fish is nearly exhausted. By this time, the fish bodies are in the state of hypothermic anesthesia and then they are to be encased. 3) the Oncorhynchus mykiss are transported by packing transportation or water track transportation. After arriving at a destination, The Oncorhynchus mykiss are brought back to life and the temperature of aquaculture water is gradually increased to normal level. The hypothermic anesthesia transportation method has following beneficial effects: no matter how much the transportation volume of live fish is, the transportation method can be performed with low cost, simple, flexible and easy operation; and the economic benefit can be guaranteed by high rate of survival of fish after transportation.

Description

Technical field [0001] The invention belongs to the field of live fish transportation, and specifically relates to a low-temperature anesthesia transportation method suitable for spotted trout live fish. Background technique [0002] Spotted trout (Oncorhynchus mykiss), commonly known as noble fish, is a species of salmonid (commonly known as salmon) fish, named for its speckled body. Spotted trout is a cold-water upstream migratory fish. It is a new artificially bred salmon species with excellent characteristics such as stress resistance, fast growth, high temperature resistance and wide salt. Due to the wide range of suitable temperature for this fish, the survival temperature is 0~23℃, the suitable water temperature is 8~21℃, the most suitable growth water temperature is 10~18℃, and the suitable salt range is wide. It can be cultured in fresh water and sea water, with salinity 0~ It can survive within 33 years; it has strong disease resistance and fast growth. The feed conver...
