Abstract
The invention discloses a high-yield mudflat cultivation method of Sipunculus nudus. The cultivation method of Sipunculus nudus is simple, low in investment and less risky; traditional cultivation in cultivation sea areas is basically a management-free or low-yield cultivation method. Years of efficient mudflat cultivation tests are performed according to physiological living habits of Sipunculus nudus, the steps such as selecting farm conditions, treating farms, selecting fry sources and specifications, raising fry, managing development and harvesting are taken, intensive high-yield mudflat cultivation of Sipunculus nudus is achieved, the cultivation period is a year and half, yield per mu is 280.0-320.3kg, mudflat cultivation yield per mu of Sipunculus nudus is increased greatly, and mudflat resources are fully utilized. The high-yield mudflat cultivation method of Sipunculus nudus is scientific and reasonable in process and highly operable; high-yield cultivation of Sipunculus nudus is achieved by reasonable and efficient use of mudflats.
Description
Technical field
What the present invention relates to is a kind of nude Sipunculus nudus beach high-yield cultivation method
,be applicable to the cultivation of coastal areas of southern China beach Sipunculus nudus, belong to technical field of aquaculture.
Background technology
Nude Sipunculus nudus
(Sipunculus nudus)claim again Sipunculus nudus, be commonly called as sandworm, be under the jurisdiction of sipunculan door
(Sipucunla),genus Sipunculus
(Sipunculus), shape, the spitting image of intestines, is long tubular, and body is about 10-20 centimetre, nude without hair, body wall clathrate decorative pattern.Nude Sipunculus nudus is coastally on the south distribution on global kind ，Yu China Qingdao all to have a distribution, wherein with Fujian and Guangdong and Guangxi Provinces coastal resources compared with horn of plenty, be one of famous marine products treasure, because welcoming in its delicious flavour, the nutritious domestic and international market that is deeply subject to.It is food that this kind be take beach organic debris and benthic algae, and food chain level is time low, strong stress resistance, and breeding ecological is very suitable for large area and propagates artificially.At present with the industrialized development of nude Sipunculus nudus artificial breeding, mudflat aquaculture area rapid growth.But because nude Sipunculus nudus breeding way is relatively simple, investment is little, and risk is little, and the cultivation of mariculture area belongs to the breeding way without management or low yield substantially.According to the output of nude Sipunculus nudus cultivation place, investigate and consult pertinent literature, learn: pond high-density breeding can be realized the high yield of Sipunculus nudus, but it is high that pond culture basic condition requires, the area that is applicable to high-density breeding is few, and mudflat aquaculture is the major way that current nude Sipunculus nudus is propagated artificially, according to this traditional breeding way, cultivate well and all produce as 100-120kg/ mu, overwhelming majority culturing area output is 30-50kg/ mu, this just makes large-scale beach be difficult to realize efficient utilization, the state that extra large Tidal Flat Resources is not fully utilized.Therefore, physiology, life habit according to nude Sipunculus nudus, and through the efficient culture experiment of beach for many years, provide a kind of for nude Sipunculus nudus beach high-yield cultivation method, for making full use of of extra large Tidal Flat Resources, excavating the growth potential of the nude Sipunculus nudus of cultivation, increase economic efficiency, is very significant.
Summary of the invention
The object of this invention is to provide a kind of nude Sipunculus nudus beach high-yield cultivation method, present situation for nude Sipunculus nudus high-density breeding method blank, carry out deep research, overcoming traditional Sipunculus nudus breeding way is the deficiency that nature is put in a suitable place to breed, carry out scientific management, rationally close growing, and then raising beach availability, increases cultivation income.
For achieving the above object, the present invention has taked following technical scheme, and a kind of nude Sipunculus nudus beach high-yield cultivation method, comprises following concrete technical step:
(1) cultivation site condition
Region, Tideland resources middle and upper part is selected in place, has the place of the nude Sipunculus nudus of natural distribution, and silt content is greater than 70%, easy the raw benthic diatom class in surface, avoids having after beach ebbs tide the region of water route process, seawater salinity 14-33, without greasy dirt and away from sanitary sewage, prohibit and throw in all poisonous insect medicines;
(2) plant ground is processed
Culturing area is made marks to insert rod, every 200m
2zone marker surrounds square region, removes part in region husky, makes culturing area a little less than beach face around, and region adopts dash article closely to form a circle along mark around, keeps culturing area to have water, dry revealing, depth of water 1-5cm after ebb;
(3) seed source and specification
Buying artificial breeding seed, select size evenly, not damaged, body colour meet oxygen pale red, press tight strong, the individuality that burrowing ability is strong of body, the specification of forming input seed is 0.1g-0.2g/ bar, and the seed that specification is less can be thrown in by marine intermediate rearing after forming input seed size again;
(4) put seedling
After beach ebb, seed is evenly sowed in culturing area, put seedling density 40-50 bar/m
2;
(5) form management
Put seedling after 1 month, cultivation density is lower than 40/m
2time, fill the gaps with seedlings to cultivation density be 40-50 bar/m
2, repair in time the broken dash article that lack, keep water, remove harmful organisms and foreign material in culturing area, after ebb in 1-2 month with the husky top layer of rake scarifying culturing area;
(6) results
Culturing time 18 months or weight reach 12-14g can be gathered in the crops, and adopts the full plane of trench-hoe to dig, and dug out according to its passage vestige during results;
Described dash article refer to facility or the article that can keep culturing area water, can adopt and put sandbag, use woven bag to fill on the spot husky rear encapsulation;
Described poisonous insect medicine refers to desinsection class agricultural chemicals, tea bran etc.;
Described sea area intermediate rearing refers to: in culture zone, put before seedling, according to cultivation, put seedling amount, taking area is 1-100 m
2square or irregularly shaped sand pit, degree of depth 8-12cm, then cover 100 object nylon mesh tulles and make spacer screen, on spacer screen, fill out sand, throw in seed 2000-3000 bar/m of Individual Quality <0.1g
2, rear covering 40 order nylon mesh tulles are made cover net, and sew up with spacer screen edge, adopt supporting construction to keep cover net and Shamian Island to leave space more than 5cm, and through 20 days intermediate rearings, seed weight reached 0.1g-0.2g, took and was invested in cultivation place;
Described harmful organisms refers to predacious fish, crab class etc.
Take the present invention of above-mentioned measure, by the selection of seed, processing and cultivation place sand are shown to the micro-processing of physics, utilize nude Sipunculus nudus life habit, make nude Sipunculus nudus adapt to cultivation place environment, greatly reduce its cultivation escapement ratio, be also beneficial to the production of cultivation place benthic diatom class simultaneously, supplement nude Sipunculus nudus bait, realized that nude Sipunculus nudus beach is intensive, high yielding culture, approximately 1 year half cultivation phase, per mu yield 280.0-320.3kg.Technological process of the present invention is scientific and reasonable; method of operating is simple, understandable; material and seed are easy to get; realize nude Sipunculus nudus beach high density, high yielding culture; the present invention propagates industrialized development artificially to nude Sipunculus nudus and has great facilitation; creative and higher practical value, and to protection and exploitation marine resources, bring about a prosperous economy, enrich seawater breed variety structure and implement the strategy of sustainable development all significant.
