Description
Technical Field
The invention relates to a freshwater fish culture technology, in particular to a fry transportation method.
Background
When the fry is transported for a long distance, because the placing density of the fry in the transport container is large, the probability of mutual scratching between the fish bodies is large, and the fish bodies are inevitably damaged in the long-time transportation process. The death rate of the fries after the fries are put into the pond is high.
Wherein the time when the fries are most easily scratched mutually is when the transport means moves at a variable speed, the water flow in the transport container is disturbed, and the fries do not have a reaction time, so that the fries are caused to be scratched mutually by collision.
Disclosure of Invention
The invention aims to solve the problem that fry collide with each other in the transportation process, and provides a fry transportation method which enables the fry to have advanced reaction time and avoids collision.
The basic scheme provided by the invention is as follows: the fry transportation method comprises the following steps of 1, pretreatment of transportation water: well water or tap water is selected as transport water, and aeration is carried out on the well water and the tap water for 1 to 2 days; and 2, injecting into a transport container: detecting the water temperature, wherein the temperature difference between the transportation water temperature and the fry original pool water temperature cannot exceed 3 ℃; step 3, injecting the fry: injecting the fry into a transport container, wherein more than one third of oxygen is injected into the transport container; and 4, transporting: transferring the transport container to a transport vehicle for transfer; step 5, feeding in the way: feeding every 6-12 hours during transportation; step 6, changing water on the way: removing the transportation water in the transportation container of 1/4-1/3 every 3-4 hours, and then supplementing new transportation water; step 7, discharging the pond: eliminating the temperature difference between the transport water and the local water temperature, and putting the fry into a fishpond of a breeding area; step 4, in the transportation process, when the acceleration of the transportation tool is forward, the rear end of the transportation container is lifted; the front end of the transport container is lifted when the vehicle is accelerated backwards, the right end of the transport container is lifted when the vehicle turns left, and the left end of the transport container is lifted when the vehicle turns right.
In the step 1, well water and tap water have less impurities, but need to be fully solarized, so that the water has the effects of sterilizing and dispersing gas in water on one hand, and the oxygen content of the water is increased after solarization on the other hand. In the step 2, because the fry is weak in physique, the fry can die due to overlarge temperature difference between two water temperatures during transfer. And 3, injecting oxygen into the transport container to enhance the dissolved oxygen in the transport water and improve the survival rate of the fry. And 5, in the long-distance transportation process, in order to prevent the fish from eating too small due to hunger, putting food such as egg white and cake dregs into the transportation container for the fry to eat. Step 6, after the food is eaten, the water quality will deteriorate, the oxygen content is reduced, and new transportation water is injected to keep the activity of the water. And 7, the water temperature difference between the transport water and the culture land is eliminated, so that the survival rate of the fry is improved.
In the transportation process, when the acceleration of the transportation tool advances or the acceleration retreats, turbulence can be formed in the transportation container, so that mutual collision and injury of the fries are caused, and therefore in the step 4 in the method, when the acceleration of the transportation tool advances, the rear end of the transportation container is lifted, and the transportation water at the rear end of the transportation container has certain gravitational potential energy, so that the pushing of the transportation container to the transportation water is offset, the transportation water in the transportation container can be relatively stable, and the fries are prevented from being damaged due to mutual collision. When the transport vehicle moves backwards, rightwards or leftwards under the acceleration, the principle of the transport vehicle is the same as that of the transport vehicle moving forwards under the acceleration, and one end of the transport container is lifted to offset the pushing of the transport container to transport water by utilizing gravitational potential energy.
Compared with the prior art, the scheme has the advantages that:
1. the problem of fry in the transport container collide because of the rivers disorder is solved.
2. The problems of temperature, water-soluble oxygen and food are fully considered in the transportation process, and the survival rate of the fry in the transportation process is improved.

The impact on the transport container during the liquid flow causes a change in pressure within the transport container, so that the triggering mechanism can determine the degree of jacking by the pressure change.
The third scheme is as follows: for the second option, the transportation water in step 1 is prepared into 0.2% saline. Has the advantages that: a certain amount of saline can inhibit the growth of bacteria and parasites, and the fry can live normally in 0.2% saline.

Has the advantages that: the fry can be collided and injured inevitably, and the penicillin can inhibit the inflammation of the wound after the fry is injured, so that the fry can be quickly self-healed, and the death rate of the fry is reduced.
And a fifth scheme: and (4) preferably, the fries transported back between the step 6 and the step 7 are put in a surrounding box of a breeding place for breeding for 1 to 2 days. Has the advantages that: the fry can adapt to local environmental temperature in a relatively closed environment after being cultured in the enclosure for 1-2 days, and the impact of environmental change on the fry is relieved.
