Problems solved by technology

[0005] 1. The method of manual fishing and manual handling requires a lot of labor and many links, and the links cannot be smoothly connected, resulting in work interruptions, resulting in too long time
[0006] 2. The anesthetized dry method or the wet method with water during manual transportation will cause greater damage to the fish and form a greater stress response. For fry that have been transported for a long distance and are weaker, it is easy to aggravate the death
[0007] 3. Manual handling is more labor-intensive

Embodiment 1

[0043] (1) The live fish cart carries coho salmon fry with a weight of 30g, arrives at the workshop door of the farm, opens the lid of the fish tank, and uses a hand-held dissolved oxygen meter to measure the water temperature and dissolved oxygen in the fish tank. The water temperature is 10°C and the amount of dissolved oxygen in water 15mg / L, the fry swim normally, without turning over, floating head and other bad conditions; the live fish truck has its own pure oxygen aeration to keep working normally, and start unloading after ensuring that there is no abnormality.

[0044] (2) Use a submersible pump to draw water from the breeding pond and pump it into the fish tank. The water temperature in the breeding pond is 15°C, and then slowly open the bottom valve of the fish tank from small to large to drain water until the water body in the original tank is completely replaced; The water temperature difference between the incoming water and the fish tank is large (5°C), so set a...

Abstract

The invention provides a method for unloading fry into a pond. The method includes the following steps that 1, after a live fish transport vehicle arrives at the scene, the water temperature and dissolved oxygen concentration of one fish tank is measured, the state of the fry is observed, and unloading work starts; 2, water is extracted from an aquaculture pond into the fish tank, until water in the fish tank is completely changed by water in the aquaculture pond; 3, a drainage valve at the bottom of the fish tank is switched on, and 1 / 3 of the water is discharged; 4, fry conveying equipment is assembled and placed near the live fish transport vehicle; 5, a submersible pump is turned on, water is injected into a conical container, a hand-held fishing net is used for catching the fry and putting the fry in the conical container, and the fry then enters a fish pipe with the water flow and finally reaches the aquaculture pond; 6, with fry catching, water discharge continues until all fryare caught; 7, when the fish tank is unloaded, the water quality of the fish tank is determined and water is changed, and unloading work of all the fish tanks is completed in turn. The method adopts uninterrupted pipeline transportation, each link has strong coherence, and the time of unloading fry into the pond can be shortened.

Description

technical field [0001] The invention relates to a method for transporting fish fry, in particular to a method for transporting fish fry from a car into a pond. Background technique [0002] In aquaculture production, fry is the key means of production. Because most farms cannot breed fry by themselves, most of them need to be purchased, so the transportation of fry has become an indispensable production activity. For farms with a large demand for fry, live fish carts are generally used to transport fry. After arriving at the farm, the fry that have been transported for a long distance are weak. Due to production and epidemic prevention requirements, large-scale farms do not allow live fish carts to drive to the side of the pond, and the extension of the distance increases the difficulty of unloading the truck into the pond. Therefore, how to unload fish fry from the fish cart in a reasonable and scientific manner And complete the transportation into the pond. During this pe...
