Problems solved by technology

The transfer method of fish suction pump, fish divider and live fish boat used abroad for this kind of fish mainly adopts the large-scale cage culture mode. During the implementation process, it needs to consume a lot of water, which is obviously not suitable for domestic ponds and industrialized farming. model

Embodiment 1

[0020] This embodiment adopts the inventive method, Atlantic salmon is made of 3 # Workshop transfer to 11 # workshop, the distance between the two workshops is 1.5km, and the specific pool transfer method includes the following steps:

[0021] 1) Preparation before anesthesia

[0022] Add fresh seawater to an anesthesia box with a length of 150cm, a width of 70cm, and a height of 55cm. The inner wall is equipped with an elastic material (foam board) anesthesia box, to a water depth of 30cm, aerated and oxygenated, and MS-222 is added to a final concentration of 60ppm. 3 times.

[0023] 2) Administer anesthesia

[0024] About 40 Atlantic salmon with an average weight of 2000g were collected and placed in an anesthesia box. They were not disturbed until the Atlantic salmon turned over; There is no response to external force disturbance, and the anesthesia period is about 8 minutes.

[0025] 3) Graded transfer

[0026] Put the anesthetized Atlantic salmon into transfer box...

Embodiment 2

[0030] Will speckled trout by 9 # Workshop transfer to 6 # workshop, the distance between the two workshops is 0.5km, and the specific pool transfer method includes the following steps:

[0031] 1) Preparation before anesthesia

[0032] Add fresh seawater to an anesthesia box with a length of 180cm, a width of 60cm, and a height of 50cm. The inner wall is equipped with an elastic material (foam board) to a depth of 30cm, aerated and oxygenated, and MS-222 is added to a final concentration of 50ppm. 3 times.

[0033] 2) Administer anesthesia

[0034] Collect about 40 spotted trout with an average weight of 2500g and put them into the anesthesia box, and do not disturb them until the spotted trout rolls over; Mobility, no response to external force disturbance, anesthesia period of about 10min.

[0035] 3) Graded transfer

[0036] Put the anesthetized spotted trout into transfer boxes (foam boxes) according to production requirements and complete the grading; then use a tr...

Abstract

The invention belongs to fish culture management technology and particularly provides a pool classifying method of swimming fishes. The swimming fishes in a culture system are moved into an anesthesia box, the swimming fishes can lose capacity of action completely by adjusting anesthetic concentration in the anesthesia box and anesthesia time of the fishes, the swimming fishes after being anesthetized are classified according to sizes and transported to other culture systems in an out-of-water mode, and then the swimming fishes are revived so that the purposes of lowering density and breeding in a classification mode can be achieved. The pool classifying method can achieve the fact that the large fishes such as Atlantic salmon of 800-3000g can be safely transported in an out-of-water mode through a classifying pool in no less than 15 minutes, and remarkably lowers a death rate within 0.2%.

Description

technical field [0001] The invention belongs to a fish breeding management technology, in particular to a pool division method for swimming fish. Background technique [0002] Salmon is the most successful farmed fish in the world, with high economic value and wide market demand. In recent years, the salmon farming industry represented by Atlantic salmon, spotted trout and rainbow trout has entered a rapid development period. [0003] In the process of aquaculture production, with the growth of fish, the aquaculture density continues to increase, and excessive aquaculture density will lead to deterioration of aquaculture water, reduce bait efficiency, inhibit fish growth, and increase the risk of fish disease outbreaks. Pool division is a technology that can quickly reduce the breeding density and realize graded stocking. Through scientific pool division, the growth of fish can be promoted, the risk of production management can be reduced, so that production resources can ...
