Description
Technical field
The invention belongs to field of aquaculture, the collection device of more particularly, to a kind of monocyclic thorn seed and method.
Technical background
Monocyclic thorn is commonly called as " Urechis uniconctus ", is Yellow Sea of China, the frequent species in Sea And Bohai Sea Coast benthon population, monocyclic thorn
Individual loose, meat flavour deliciousness, body wall flesh rich in proteins and multiple essential amino acid, in China, Japan and Korea S
Coastal all by as famous and precious seafood, have higher economic worth.Because catching intensity was excessive in recent years, monocyclic thorn
Stock number drastically decline, its artificial breeding, aquaculture work start to be taken seriously.
Although by research of technique in recent years, monocyclic thorn artificial breeding and cultural technique achieve a certain degree of prominent
Broken, but also there are other problemses, due to needing aborning to mat formation, sand bed perches substrate as seed, and sand bed uses one simultaneously
Nigrescence, smelly phenomenon occur, Seedling growth is suppressed, and now must be collected seed and move in new pond after the section time
Continue to cultivate.But seed collection work difficulty is big, Seedling damages seriously, leads to survival rate to reduce, and governs Seedling production and supports
Grow the large-scale development of production.When at present with regard to solving monocyclic thorn indoor culture, the labor intensity leading to because collecting seed
Greatly, the problems such as Seedling is impaired serious, is not reported both at home and abroad.
Content of the invention
Present invention aims to deficiency of the prior art, provide one kind can solve to collect process in seed
In, the impaired serious collection device of high labor intensive, seed and method.
For solving above-mentioned technical problem, the technical scheme is that：
A kind of collection device of monocyclic thorn seed, includes water inlet pipe 1, supervisor 2, athwartship leg 3, oblique nozzle 4, horizontal
Nozzle 5, valve 6, oblique arm 8；Water inlet pipe 1 one end is connected with flexible pipe 7 by valve 6, the other end and supervisor the vertical phase of 2 side walls
Logical；2 one end are vertical communicates with supervisor for athwartship leg 3, and are vertically installed with multiple horizontal nozzles 5 on athwartship leg 3 side wall, main
At least one oblique arm 8 is arranged on pipe 2 side wall, and each oblique arm 8 top is separately installed with oblique nozzle 4.

Preferably, 6 oblique nozzles of setting, 2 horizontal nozzles, oblique arm in device（8）Number and oblique nozzle
（4）Number consistent.
Preferably, oblique nozzle, horizontal nozzle are the flat shape of the mouth as one speaks.
The present invention also provides a kind of collection method of monocyclic thorn seed, and the collection device being provided using the present invention, by list
The collection device that ring pierces seed is placed in the culture pond 9 with drain pipe 12, and athwartship leg 3 is in culture pond away from row
The inwall of water pipe, drainage pipe end is provided with receipts Seedling bag 13, and the water inlet of collection device is connected with water pump simultaneously, and collection device can
To move freely, specifically used step is：
Step 1, first time draining：Open drain pipe, when in culture pond water level decreasing to sand bed 11 in culture pond on
When at portion 10cm, close drain pipe；
Step 2, sand surfing and second draining：Open water pump, be again turned on drain pipe, collection device is from culture pond away from row
One end of water pipe starts sand surfing；
Step 3, flow rate regulation：During carrying out step 2, control valve 6, adjust sand surfing current size it is ensured that rushing
Husky current can penetrate sand bed, so that Seedling is fully floated；
Step 4, seed are collected：By the effect of current, Seedling is separated from loosening sand bed, to drain pipe direction
Mobile, and enter receipts Seedling bag 13 with water drain stream through drain pipe 12.
Preferably, in step 2, the horizontal nozzle 5 of collection device is towards the sand surfing of drain pipe direction, oblique nozzle 4 and sand
The Shamian Island of bed be in 45 ° oblique put in sand bed, and keep oblique and gradually move forward.
The present invention is compared with prior art advantageously：Collection device provided by the present invention and collection method,
Change monocyclic thorn seed at present and collect commonly used sieve sand, elutriation mode, adopt with the method for water pump sand surfing, by spy
The sand surfing device of system is arranged on water pump water outlet pipe end, so that sand is stirred and will float out in Miao Congsha, relends and help current
Effect is allowed to the concentration that separates with sand and conflux, and finally collects Seedling.As support, with brand-new fry collection device with
Collection method, faster and better can collect out by perching the monocyclic thorn seed in sand bed, reduce because sand bed black, smelly
The impact that Seedling growth is caused, seed gathering speed can be improved 2-3 times by the method, and Seedling damage ratio reduces by more than 50%.
