Description
Technical field
The invention belongs to aquatic animal artificial fecundation to release field, be specifically related to a kind of fish fry artificial fecundation and release method.
Background technology
Along with the impact of the human factors such as overfishing, water pollution aggravation, water project construction increase, fishery resources fail year by year.In order to protect bio-diversity, improve the sustainable development of water area ecological environment and promotion fishery, fish stock increasing activity of releasing in recent years is more and more subject to the attention of relevant departments.
So-called enhancement releasing be exactly by manual type to ocean, rivers, the public waters such as lake release the activity of aquatile seed or parent; increase water area resource amount; its Natural Population recovered, is maintenance living aquatic resources, protect bio-diversity, improve water area ecological environment and promote effective measures of fisheries sustainable development.
China is from the eighties in 20th century, in order to recover natural water area fishery resources population quantity, first Chinese prawn enhancement releasing has been carried out in the yellow Bohai Sea, release at coastal, that inland waters have all carried out certain scale Fishery Resources Enhancement successively subsequently, propagation kind has Chinese prawn, japonicus, swimming crab, jellyfish, black porgy, black Jun, lefteye flounder, " four large Chinese carps ", carp, crucian carp, Sinensis eriocheir sinensis, mandarin sturgeon, mullet, giant salamander etc., and visible fish multiplication is released and occupied very large proportion wherein.
Traditional fish multiplication release method and the enhancement releasing such as Shrimp waste, jellyfish method basically identical, all adopt the mode of plastic sack oxygenation packing, due to the particularity of fish fry, oxygenation packing is wasted time and energy, for 3cm black porgy seedling of releasing, according to the packing instructions of 100 tail/bags, 1,000,000 tail fries of releasing need packing 10,000 bag, calculate according to everyone average 100 bags of making a call to per hour of experienced operator, 10 experienced operators need continuously uninterrupted packing 10 hours; To transport vehicle be loaded onto after on the other hand fry has played bag, then be transported to by transport vehicle harbour of releasing, then fry carrying is gone on board, go to sea afterwards and release, whole process operation flow process is complicated, the time is longer, comparatively large to fry damage, be unfavorable for surviving of fry; Meanwhile, labour intensity is large, and labour cost, fee of material, fare, fare etc. also bring no small financial burden to family of releasing.
Summary of the invention
The present invention is to traditional fish fry enhancement releasing method reform, whole process of releasing adopts the transport of running water car, without the need to oxygenation packing process, without the need to renting boats and ships, after running water car is transported to place of releasing, adopt defeated fish pipeline to receive on running water car water tank, directly by fry through defeated fish discharge of pipes to target marine site.The method operating procedure is simple, quick, efficiency is high, little to fry damage, survival rate is high, and labour intensity is low, saves a large amount of manpowers, financial resources, material resources.
A kind of fish fry artificial fecundation is released method, and step is:
1) prepare before releasing: select seed, release waterwheel or water tank and defeated fish pipeline of releasing;
2) fry entrucking: before fry entrucking, to releasing, waterwheel or water tank, defeated fish pipeline and other apparatus of releasing carry out disinfection; Control the release amount of water of waterwheel or water tank, oxygenation capacity and water temperature; Fry density is controlled during entrucking;
3) fry is released: be communicated with release waterwheel or water tank defeated fish pipeline one end, one end is put into target marine site of releasing and released.
Further, in described step 1), defeated fish pipeline employing diameter is the plastics wired hose of 50-75mm.
Further, release described in described step 1) waterwheel or water tank bottom are provided with bottom valve, and described defeated fish pipeline one end is provided with pvc adapter, and described defeated fish pipeline is communicated with release waterwheel or water tank bottom valve by pvc adapter.
Further, described step 2) in amount of water be apart from water tank within 10cm, dissolved oxygen is more than 6mg/L.
Further, described step 2) in water temperature control 2-3 DEG C under target marine site water temperature of releasing.
Further, in described step 3), fry is released and to carry out when flood tide or full sea.
Further, the length in target marine site of releasing put into by the defeated fish pipeline of described step 3) is 15-30m.
Further, when described step 3) is released, defeated fish water flow in pipeline speed is 0.6-1.2m
3/ 10 minutes.
Further, described step 2) in entrucking time fry density, 3cm black porgy seed 2-3 ten thousand tails/m
3, 5cm black Jun seed 1.5-2 ten thousand tails/m
3, 4cm perch seed 2-2.5 ten thousand tails/m
3.
Compared with prior art, advantage of the present invention and good effect are:
1) time of releasing is short, and efficiency is high: present invention eliminates oxygenation, packing, entrucking, unload, the complex process such as shipment, and packing and shipping compared with the method for releasing with traditional oxygenation saves time 70%, and efficiency is high.
2) fry damage is little, survival rate is high: whole process of releasing is minimum to fry damage, particularly put seedling process to fry almost not damaged by running water car by defeated fish pipeline, extend defeated fish pipeline distance in the seawater simultaneously, be conducive to fry to adapt to gradually to release the water temperature in marine site, be conducive to fry and survive.
3) labour intensity is low, save manpower, financial resources, material resources: present invention eliminates oxygenation, packing, entrucking, unload, the complex process such as shipment, after fry is transported to destination of releasing, by pipeline communication, greatly reduce labour intensity, save a large amount of manpowers, financial resources, material resources.
