Description
Technical field
The invention belongs to technical field of aquaculture, it is related to avoiding causing fish body when squama fish is cherished in a kind of fishing pond culture
The method of injury.
Background technique
Hilsa herring and hairtail are domestic most rare breed varieties, are " cherishing squama fish ".The two has very much like physiology
And behavioural characteristic: their bodies are delicate, edgy, and scale is slim soft, easy to fall off；When stress reaction, scale is easily de-
It falls.Since the two is migration fishes, scale is not only important body surface protective layer, and the epidermis on scale is even more osmotic pressure tune
One of vitals of section.After scale falls off, osmotic pressure functional disturbance may finally lead to death.
Hilsa herring and hairtail have similar cluster to move about behavior: under normal circumstances, they, can be along in breeding water body
The travelling of cluster forward that pool side carries out marshalling in one direction, not stopping, will not original place it is static or turn to travelling.When by
To when frightening, gathers rapidly, moved about along fixed direction with faster speed cluster；It will not reverse end for end, cause when encountering dead angle
It is badly battered；It is poor to the suffertibility of sewage to cherish squama fish, when being caught, stress reaction is strong, hits mesh sheet or mutually collides pole
It easily causes that scale falls off or head is congested, leads to death.So the scale that squama fish is cherished in protection is very important when fishing.
When cherishing squama fish of pond culture is caught with traditional pulling method, difficulty is bigger, not only can cause to damage because of shock,
And can be because of the bed mud that seine inevitably stirs, slurry sewage can choke fish, or because the hauling current political situation to death in seconds
Portion's anoxic leads to death by suffocation, badly wounded by the fish of seine, can not continue to cultivate.By taking hilsa herring pond culture as an example, fishing
Effect depends on the experience of worker, generallys use local seine, the method caught all in one draft, fish that has escape the net will certainly die undoubtedly.Due to drawing
Net, that is, dead, pond culture hilsa herring and hairtail, can not capture live fish, can not use the cultural method of multiple stocking and multiple fishing.So can only
At cultivation initial stage, sufficient seed is disposably put, to cause the waste in pond space；Moreover, scale falls off or body surface is impaired
It causes to be marred by a scar, etc., especially the hilsa herring to cuisines scale, more seriously affects sale and price, cause biggish economic loss.It is " hilsa herring
Fish and hairtail pond culture are not easy, and fishing risk is bigger ", " seine is i.e. dead ", which has become, influences hilsa herring and hairtail pond culture industry
One of problem of development.
Cherish the most important physiological characteristic of squama fish first is that edgy, and behavior is fierce and tough, and the threshold value of stress reaction is lower.
In the case that stress, to dissolved oxygen demand double, thus to fishing constitute fatal challenge.Many physiology of fishes men think,
Hilsa herring and hairtail are because caused by its gill portion structure feature to dissolved oxygen and environmental ecology condition stress reaction extremely sensitivity.With other
Fish is compared, and the gill portion tissue surface product of the two is smaller, they need to be by the way that constantly travelling generates " punching press breathing " forward
Mode obtains enough dissolved oxygens.When cherish squama fish encounter seine etc. stress factors threaten when, since stress reaction is excessive, to dissolved oxygen
Requirement multiplication easily causes death by suffocation in addition the aggravating circumstances such as slime water that seine stirs are easy the very thin gill portion of damage
It dies, we term it " irritability anoxics ".It is newest to hilsa herring irritability anoxia phenomenon studies have shown that when temperature is more than 24 DEG C
When, when receiving net with seine fishing hilsa herring, although dissolved oxygen, in 6ppm or more, hilsa herring can be all dead in 8 minutes in seine；This
It is because in a smaller space, they can not move about, and lose " punching press breathing " function, and anoxic exacerbates stress reaction and life
Oxygen deficit is managed, hilsa herring and hairtail more insanely collide mesh sheet, and mutually collide, and cause a large amount of scales to fall off, in addition seine stirs
Slime water damaged gill portion, reduce gill portion obtain dissolved oxygen function, eventually lead to irritability anoxic, death by suffocation.
For this purpose, the present invention according to cherish the current research of the biological property of squama fish, physilogical characteristics and behavior specificity at
Fruit is taken measures to meet its travelling behavior and psychological need, the corner of the one end in pond is arranged in using magnetic force side enabling net cage,
The shoal of fish is driven in into the enabling of net cage rear enclosed side with blocking and driving stick without section, can effectively avoid death by suffocation caused by irritability anoxic
It dies, to realize that not damaged interception is fished with relatively simple method.
