Abstract
The invention discloses a method for preventing exposure and desiccation of Babylonia aerolata seedlings. The phenomenon of death of a large number of Babylonia aerolata seedlings caused by exposure and desiccation can be easily caused in a seedling production period, the death often happens in a stage during which the seedlings are transferred to bottom dwelling in the later period of seedling cultivation and the body length reaches about 3mm, and the death phenomenon brings great harm to the production of Babylonia aerolata seedlings. The method disclosed by the invention mainly comprises the following steps: 1, preparing a seedling cultivation pond; 2, laying an exposure and desiccation prevention isolation zone for the seedlings; 3, putting the seedlings into the pond; 4, carrying out cultivation management. Due to the adoption of the means, the problem of exposure and desiccation of the seedlings of Babylonia aerolata during an artificial seedling cultivation period is effectively solved; the method disclosed by the invention has inventiveness and advancement and also has very high practical value. The method disclosed by the invention is high in targeting property, is applied after multiple practices, dispenses with occupying extra resources, and is low in use cost, simple to operate and good in using effect.
Description
Technical field
The present invention relates to a kind of Babylonia areolata (Lamarck) seedling and prevent dry dew method, belong to marine aquaculture technical field.
Background technology
Babylonia areolata (Lamarck) (
babylonia areolata) being commonly called as " Neptunea cumingi ", " flower spiral shell ", classification belonging to Gastropoda, Caenogastropoda, E Luoke, is the seashells that a kind of edible economic worth is higher.This spiral shell delicious flavour, be of high nutritive value, be one of south China marine site Main Economic shellfish, at present, market price is many at 100 yuan/more than kg, and supply falls short of demand for product.Babylonia areolata (Lamarck) growth cycle is short, economic worth is high, has the features such as small investment instant effect, in recent years this kind artificial breeding and cultivation in the ascendant in south China each province, but correlation technique level is uneven, the farming disease harms in this kind artificial breeding process is caused to take place frequently.Find in the production practices of nearly 2 years; Babylonia areolata (Lamarck) often there will be a large amount of seedling dry dew phenomena of mortality at nursery production period; the dead later stage seedling generally occurring in nursery proceeds to the end and dwells; body reaches this stage of about 3 millimeters, and this phenomenon is produced to Babylonia areolata (Lamarck) nursery and brought very large harm.Therefore seek that a kind of to solve the method that Babylonia areolata (Lamarck) seedling does dew dead be highly significant.
Summary of the invention
Technical problem to be solved by this invention is in Babylonia areolata (Lamarck) room heat source process at present, seedling is the protrusion phenomenon of death due to dry dew, a kind of Babylonia areolata (Lamarck) seedling is provided to prevent dry dew method, overcome the nursery failure that current Babylonia areolata (Lamarck) artificial breeding causes because seedling does dew death, improve the survival rate of Babylonia areolata (Lamarck) room heat source, thus reduction seedling cost, increase economic efficiency.
Take following technical scheme to solve the problems of the technologies described above, a kind of Babylonia areolata (Lamarck) seedling prevents that dry dew method mainly comprises the following steps:
1, the preparation of nursery pond: Babylonia areolata (Lamarck) nursery pond 3.8m × 4.5m, the dark 1.3m in pond, be equipped with oxygenation facility and culvert system, at the bottom of pond, four limits are provided with discharge outlet, special-purpose aqueous environmental protection paint is produced in nursery pool wall and pond basal surface swabbing, nursery pond pool wall becomes the gradient with at the bottom of pond, and gradient horizontal range is 0.03-0.1m;
2, the anti-dry dew isolation strip of seedling is laid: according to nursery height of water level, a stickup line contour with nursery water level is drawn at nursery pond inwall, get isolation strip and paste a circle along pasting line, article two, do not stay gap between isolation strip, described isolation strip is prepared by sponge, and specification is the strip of 100-240cm × 3-8cm × 1-2cm;
3, seedling enters pond: before Babylonia areolata (Lamarck) seedling enters pond, with 20ppm liquor potassic permanganate, full pond is carried out disinfection, add fresh sand filtration seawater the previous day putting seedling, water lev el control is higher than more than 1cm bottom isolation strip, be drawn in collection seedling bag with the siphonage Babylonia areolata (Lamarck) being developed to abnormal early stage swum seedling, rinse well gently with sand filtration seawater, then be put in nursery pond and cultivate, control at 0.2 ~ 0.5/ml;
4, cultivating and managing: every day thoroughly changes water twice, Micro Algae bait of throwing something and feeding for 1-2 time every day, feeding volume is 30-50 × 10
4cell/ml, successfully animal bait is changed into from feeding plant bait in order to enable Babylonia areolata (Lamarck) seedling, also need to add except throwing single-cell algae and throw spirulina powder and fairy shrimp nauplius, every day throws something and feeds 1-3 time, to throw something and feed 30-50g/100 ten thousand seedlings at every turn, spirulina and fairy shrimp ratio are 0.1-0.2:1, Babylonia areolata (Lamarck) seedling is abnormal for dwelling life at the end from life of swimming through the cultivation of 3-5 days, the EDTA solution of a nurturing period full pool spilling head 3-5 ppm is to promote neat metamorphosis, firm abnormal seedling swashes to isolation strip along pool wall and namely can fall at the bottom of Hui Chi, period will notice that the suitable seawater of seedling as do not climbed out of in time embedded individually in sponge hole, isolation strip sprinkles, after Babylonia areolata (Lamarck) seedling body reaches 5mm, along with the increase of weight own, a large amount of dry dew phenomena of mortality can not be there are again, now indoor seedling is bred as ripe,
Described nursery height of water level is 0.8m-1.2m;
Described sand filtration seawater refers to the seawater through three grades of sand filtrations extracted from natural waters, water temperature 22 DEG C ~ 32 DEG C, salinity 28 ‰ ~ 35 ‰, pH value 8.0 ~ 8.5, dissolved oxygen is greater than 4mg/l, and biochemical oxygen demand is less than 1.0 mg/l, ammonia nitrogen is less than 0.6 mg/l, salinity 25 ‰ ~ 35 ‰, pH value 7.6 ~ 8.3;
Described Micro Algae bait refers to by introducing a fine variety, after conservation artificial expand cultivate gather marine green alga, chlorella, Isochrysis galbana, Dicrateria inornata or Chaetoceros muelleri a kind of or any combination containing algae liquid.
The present invention by arranging isolation strip in nursery pond, and a series of nursing measures during cultivating and managing, and the effective seedling solved during Babylonia areolata (Lamarck) artificial breeding does dew problem, and method has originality and advance, has very high practical value.The property of the present invention is directed to is strong, and is applied by repeatedly putting into practice, and without the need to taking extra resource, use cost is cheap, simple to operate, and result of use is good.
