Description
Technical field
The invention belongs to field of aquaculture, particularly relate to gathering unit and the method for a kind of Urechis uniconctus seed.
Technical background
Urechis uniconctus is commonly called as " extra large intestines ", it is the frequent species in Yellow Sea of China, Sea And Bohai Sea Coast benthon population, Urechis uniconctus is individual loose, meat flavour is delicious, body wall flesh is rich in protein and multiple essential amino acid, coastal all by as famous and precious seafood in China, Japan and Korea S, there is higher economic worth.Because catching intensity was excessive in recent years, the stock number of Urechis uniconctus sharply declines, and its artificial breeding, aquaculture work start to come into one's own.
Although by research of technique in recent years, Urechis uniconctus artificial breeding and cultural technique achieve breakthrough to a certain degree, but also there is other problems simultaneously, owing to needing aborning to mat formation, husky bed perches matrix as seed, and husky bed there will be blackout, smelly phenomenon after using a period of time, the growth of Yi seedling is suppressed, and now seed must be collected and move in new pond and continue to cultivate.But seed collection work difficulty is large, the damage of Yi seedling is serious, causes survival rate to reduce, governs the large-scale development of Seedling production and breeding production.Time at present about solution Urechis uniconctus indoor culture, the labour intensity caused because collecting seed is large, the impaired problem such as seriously of Yi seedling, is not reported both at home and abroad.
Summary of the invention
The object of the invention is to for deficiency of the prior art, provide one can solve in seed collection process, labour intensity is large, the impaired serious gathering unit of seed and method.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A gathering unit for Urechis uniconctus seed, comprises 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, and the other end communicates with supervisor's 2 sidewalls orthogonal; 2 one end are vertical communicates for athwartship leg 3 and supervisor, and athwartship leg 3 sidewall is vertically installed with multiple horizontal nozzle 5, be responsible on 2 sidewalls and arrange at least one oblique arm 8, and each oblique arm 8 top is separately installed with oblique nozzle 4.
Preferably, be parallel to each other between oblique arm 8, each oblique arm 8 respectively and athwartship leg 3 and to be responsible for the plane formed between 2 be 45 ° of angles.
Preferably, arrange 6 oblique nozzles in device, 2 horizontal nozzles, the number of oblique arm (8) is consistent with the number of oblique nozzle (4).
Preferably, oblique nozzle, horizontal nozzle are the flat shape of the mouth as one speaks.
The present invention also provides the collection method of a kind of Urechis uniconctus seed, adopt gathering unit provided by the invention, the gathering unit of Urechis uniconctus seed is placed in the cultivation pond 9 with drainpipe 12, athwartship leg 3 is near the inwall cultivated away from drainpipe in pond, drainage pipe end is provided with receives seedling bag 13, the water inlet of gathering unit is connected with water pump simultaneously, and gathering unit can move freely, and the concrete step that uses is:
Step 1, first time draining: open drainpipe, when cultivating pool inner water position and dropping to husky 10cm place, bed 11 top in distance cultivation pond, close drainpipe;
Step 2, sand surfing and second time draining: open water pump, again open drainpipe, gathering unit from cultivate pond away from drainpipe one end sand surfing;
Step 3, velocity of flow adjust: in the process of carrying out step 2, by-pass valve control 6, regulates sand surfing current size, ensures that sand surfing water flow energy penetrates husky bed, Yi seedling is fully floated;
Step 4, seed are collected: by the effect of current, and Yi seedling is separated from the husky bed loosened, and moves to drainpipe direction, and flow through drainpipe 12 with water drain and enter and receive seedling bag 13.
Preferably, in step 2, the horizontal nozzle 5 of gathering unit is towards the sand surfing of drainpipe direction, and oblique nozzle 4 and the Shamian Island of husky bed are 45 ° and obliquely put in husky bed, and keeps oblique and move gradually forward.
The present invention is compared with prior art advantageously: gathering unit provided by the present invention and collection method, change current Urechis uniconctus seed and collect the sieve sand, the elutriation mode that generally adopt, adopt with the method for water pump sand surfing, special sand surfing device is arranged on pumping line end, sand is stirred and Yi seedling is out floating from sand, relend and help the effect of current to make it be separated with sand and conflux concentrated, finally Yi seedling is collected.As support, with brand-new fry collection device and collection method, the Urechis uniconctus seed perched in husky bed can be collected out faster and better, reduce because of husky bed blackout, smellyly Yi seedling grown to the impact caused, seed gathering speed can be improved 2-3 doubly by the method, and Yi seedling damage ratio reduces by more than 50%.
