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
The invention belongs to a kind of fish culture administrative skill, specifically a kind of minute pond method of swimming property fish.
Background technology
Salmon (Salmon) is the most successful in the world cultured fishes, have very high economic worth and the market demand widely. in recent years, stepped into fast-developing period in China take Atlantic salmon and spot trout salmon, rainbow trout as the salmon aquaculture industry of representative.
In the breeding production process, along with the growth of fish, cultivation density constantly increases, and the too high meeting of cultivation density causes breeding water body to worsen, reduce bait efficient, suppresses fish growth, also can increase the risk of fish disease outburst simultaneously.Minute pond be a kind of can the fast reducing cultivation density, realize the technology that classification is put in a suitable place to breed.Minute pond by science can promote fish growth, reduces production management risk, thereby reasonably plans as a whole to distribute the resources of production, enhances productivity.
At present, the traditional fish of China divide the pond method more coarse, multiplex plastic crate, basin, bucket transhipment, this method cause fish stress be seriously, easily injured, lethality is high.Salmon belongs to swimming property fish, and feeding habits are violent, are subject to and stress injure.The transporting mode that the fishpump that abroad adopts for this type of fish adds fish grader and live fish carrier mainly uses large-scale cage culture pattern, in implementation process, needs to consume a large amount of water, obviously is not suitable for domestic pond and industrialized aquaculture pattern.Therefore, need a kind of tallying with the national condition of research and development badly, and be applicable to minute pond method take Atlantic salmon and spot trout salmon as the swimming fish of representative.
Gavaculine ethyl ester mesylate (MS-222) is through the U.S. FDA authentication, can be applicable to the anaesthetic of fish.It is good that this product has an anaesthetic effect, long action time, and recovery is fast, and the noresidue advantage such as have no side effect is widely used in transportation of live fish, parent population and adopts in the production such as ovum, inoculation and live body surgical procedure and scientific experimentation operation.
Summary of the invention
A kind of minute pond method that the purpose of this invention is to provide swimming property fish.
For achieving the above object, the technical solution used in the present invention is:
A kind of minute pond method of swimming property fish, cultivating system went swimming fish are moved to the anesthesia case, anaesthetize anaesthetic concentration in case and make swimming property fish can lose mobility fully to the anesthesia durations of fish by adjustment, and the dried up time is greater than 15min safely, swimming property fish size fractionation after anaesthetizing subsequently, and dried up being transported in other cultivating system, then recover to realize to reduce the purpose that density and classification are put in a suitable place to breed.
Described swimming fish are that body weight is Atlantic salmon or the spot trout salmon of 800-3000g.
Described anesthesia case is the casing that inwall is provided with elastomeric material, and the dark 30-40cm of water body in the anesthesia case.
Described anesthesia case is long 150-200cm, wide 60-70cm, and high 50-60cm inwall is provided with the casing of elastomeric material.
Described anaesthetic is gavaculine ethyl ester mesylate (MS-222); Anaesthetic concentration is 40-70ppm, and anesthesia duration is 7-15min.
When will realize holonarcosis to swimming property fish, it is carried out classification and fish for, then utilize trailer or fork truck to carry out dried up transportation to anaesthetizing Atlantic salmon.
In the culturing pool of described recovery swimming property fish, Nutrient solution is 120-200%, and water velocity is 18-25cm/s.
The present invention has advantages of:
Anaesthetic MS-222 of the present invention is safe, and anaesthetic effect is good.To can realize simultaneously minute pond and classification purpose after fish anesthesia, reduce transport process and stress injure Atlantic salmon, significantly reduce in lethality to 0.2%.
The present invention is in conjunction with Atlantic salmon and spot trout salmon biological property, plan as a whole the relation of anaesthetic concentration, anesthesia duration and Atlantic salmon anaesthetic effect by optimization, can effectively avoid excessively anaesthetizing phenomenon and occur, and can realize larger specification Atlantic salmon and spot trout salmon (800-3000g) are no less than the safety pond transhipment in dried up minute of 15min.To ensure fish welfare to improving breeding production efficient, realize that healthy aquaculture has great importance.
Embodiment
In the following examples, the present invention is further elaborated, but the invention is not restricted to this.
Embodiment 1
This embodiment adopts the inventive method, with Atlantic salmon by 3
#The workshop is transported to 11
#The workshop, two workshops are at a distance of 1.5km, and specifically a minute pond conveyer method comprises the following steps:
1) prepare before anesthesia
Fresh seawater is added long 150cm, and wide 70cm, high 55cm, inwall are provided with (cystosepiment) anesthesia case of elastomeric material, and to depth of water 30cm, aeration aerating adds MS-222 to final concentration 60ppm, and the anesthesia water body must not reuse over 3 times.
2) implement anesthesia
The about 40 tail average weights Atlantic salmon that is 2000g is concentrated to fish for put into the anesthesia case, occur refusing disturbance before the rollover phenomenon to Atlantic salmon; After rollover occurring, the interval certain hour carries out artificial disturbance, until Atlantic salmon loses mobility fully, externally force-disturbance is reactionless, and the anesthesia cycle is 8min approximately.
3) classification transhipment
Divide different size to put into respectively transport box (bubble chamber) by Production requirement the Atlantic salmon of implementing to anaesthetize, complete classification; Utilize subsequently fork truck with it from 3
#The workshop is dried up is transported to 11
#The workshop.Put into transport box to being transported to 11 from the Atlantic salmon that will implement to anaesthetize
#The workshop culturing pool approximately 15min that takes time altogether.
4) recovery
It is 150% that transport box central Atlantic salmon is put into Nutrient solution, and water velocity is the culturing pool of 20cm/s, and the recovery time is 15min approximately; Approximately the 6h Atlantic salmon recovers active, and dissolved oxygen level in culturing pool is adjusted to daily breeding production state.Dead 3 tails in this embodiment Atlantic salmon 2500 tails that cotransport, 6h, dead 3 tails altogether in 24 hours, lethality is lower than 0.2%.
