Abstract
The invention discloses a large-scale cultivation method for Tapes dorsatus spats. The method comprises 1. inducing parent Tapes dorsatuses to ovulate/ ejaculate through drying in shade or ammonia stimulation, hatching oosperms in an indoor cement pond; 2. cultivating spats without water exchange; 3. taking a net box made form a 120-mesh bolting sieve as a substratum when the spats grow to a metamorphosis setting stage; 4. cleaning and disinfecting a pond before the spats are moved to the pond to be cultivated; and 5. collecting the spats in the net box and transporting to the pond to be cultivating. By adopting the large-scale cultivation method, defects of complex operation and frequent pond changeover of conventional indoor cement pond spats cultivation can be overcome, and problems those spats may be damaged, the survival rate of the spats is influenced and the spats cannot be cultivated in a large-scale industrial mode caused by the defects can be solved, the invention provides a large-scale cultivation method for spats, and the spats can be cultivated in a large scale. The large-scale cultivation method for Tapes dorsatus spat establishes an important spat guarantee base for development of Tapes dorsatus aquaculture industry, so the large-scale cultivation method has a significant impact on promotion shellfish cultivation and new species exploitation and application.
Description
Technical field
The present invention relates to shellfish seedling large-scale cultivation field, relate to a kind of seedling method for massively culturing of Tapes dorsatus particularly.
Background technology
Tapes dorsatus (Tapesdorsatus) is commonly called as sand hill, belonging to Mollusca (Mollusca), lamellibranchiata (Lamellibranchia), curtain clam order (Veneroida), Veneridae (Veneridae), is a kind of large-scale torrid zone, subtropics marine commercial molluscs.Tapes dorsatus is mainly distributed in PSW, as South China Sea, the Japanese Ryukyu Islands, Philippine, India (Bombay and Le Denaji in), Indonesia (Moluccas), Australia (Brisbane, angle, York and Tasmania) and New Zealand (Stewart Island) etc.Be common in the East Sea, South China Sea and TaiWan, China island in China littoral, wherein ALONG GUANGXI COAST has certain wild Tapes dorsatus resource.Tapes dorsatus mainly inhabits in intertidal zone, low tidal region in the silt substrate of subtidal zone and shallow sea 3 ~ 15cm, life of dwelling is buried by battalion, also perches in bottom, intertidal zone coral block and rubble silt.It has the advantages such as individuality is large, growth is fast, product are of fine quality, wide adaptability, and existing market price reaches 30 ~ 60 yuan/kg, is the marine shellfish that a kind of economic worth is higher.
Current China mariculture gross yield 80% from shellfish, shellfish culture has developed into industry national economy being had to material impact.Along with the raising of people's living standard, presenting of consumption demand diversification situation, consumer no longer contents just to the consumption demand to popularity seafoods such as traditional economy shellfishes, and more and more focuses on the pursuit to delicious flavour, nutritious undeveloped edibility shellfish.Therefore, new shellfish culture kind is developed imperative.ALONG COASTAL FUJIAN oceanic area is vast, and the long complications in coastline, define many natural harbors, and sandy beach area is broad, for Tapes dorsatus cultivation provides advantageous condition.Eighties of last century ALONG COASTAL FUJIAN has the distribution of a small amount of Tapes dorsatus wild resource, almost disappeares so far.Tapes dorsatus, as a kind of new breed variety, has higher economic worth and cultivation development prospect.Therefore, carry out the technical research of Tapes dorsatus seedling large-scale cultivation, realize seedling large-scale production, established important seedling for the development of its aquaculture industry and ensured basis.It is for promotion China's shellfish culture new varieties and apply significant.
Summary of the invention
The object of the present invention is to provide a kind of seedling method for massively culturing of Tapes dorsatus.
Technical scheme provided by the invention is as follows:
A seedling method for massively culturing for Tapes dorsatus, it comprises the steps:
1) close shellfish is hastened parturition: adopt the induced spawning method drying in the shade and stimulate in conjunction with ammoniacal liquor, and close shellfish is dried in the shade 0.5-3 hour, ammonia concn 100-150ml/m
3, stimulate close shellfish to be stretched out by water pipe external and after starting to discharge smart ovum on a small quantity, closeer shellfish moved into 10-20m
2discharge smart ovum in nursery pond, support in close shellfish immigration storage pond, holding pond temporarily until discharge after smart ovum terminates;
2) larvae cultivation: adopt during whole floating larvae and do not change water method and carry out larvae cultivation, strict control larvae cultivation density (4-5/ml), bait (based on chlorella) feeding volume increases to 5-6 ten thousand cells/ml gradually by 1-2 ten thousand cells/ml, appropriate interpolation EDTA and photosynthetic bacteria regulating water quality; Water temperature 22-25 DEG C during larvae cultivation, salinity 25-30, pH value 8.0-8.5, about need 5-7 days from D type larvae cultivation to Creeping larva;
3) abnormal attachment: when larval growth is to the long 220-250 μm of shell, start to throw in adherance when foot is stretched out external exploration by the larva of more than 50%; Adherance adopts 100-150 mesh sieve thin,tough silk to make net cage and puts into nursery pond, then the Creeping larva of collection is put into net cage attachment;
4) Tu Chi levels: before juvenile mollusk moves into Tu Chi (1-10 mu) cultivation, and reply Tu Chi levels; Tu Chishui is drained, removes mud, tan by the sun 1-2 week, spread the following fine sand 4-5cm of φ 0.8mm at native pond bottom even; Seawater is through 200 mesh sieve tulle filtered water inlets, and the water yield is as the criterion to flood at the bottom of pond; With bleaching powder 10-15kg/ mu full pool spilling head, drain Chi Shui after 2 days, then intake, repeatedly secondary; Throw in the last week at juvenile mollusk, Tu Chi is intake 35-45cm, and apply urea 3-5ppm, sodium dihydrogen phosphate 0.3-0.5ppm is to cultivate biological feed;
5) juvenile mollusk Tu Chi cultivates: the juvenile mollusk collecting long more than the 1mm of net cage mesochite, moves to Tu Chi and cultivates; The harmful organisms such as regular removing fish, crab, snail; Water temperature 22-32 DEG C, under the condition of salinity 25-30, the Tu Chi through 2-3 month cultivates, and juvenile mollusk grows to the long 1-2cm of shell;
Wherein, step 1) in, close shellfish is preferably dried in the shade 0.5-1.5 hour, ammonia concn 120ml/m
3.
Wherein, step 2) in, adopt the larvae cultivation method of not changing water, when water temperature 22-25 DEG C, D shape larva was cultivated through 5-7 days, and larva can reach 220-250um, entered the abnormal setting stage.
Wherein, step 3) in, preferably adopt 120 mesh sieve thin,tough silk to make the adherance of net cage as larva.
Wherein, step 5) in, at water temperature 22-32 DEG C, long more than the 1mm juvenile mollusk of shell is cultivated through 2-3 month Tu Chi, and juvenile mollusk can grow to the long 1-2cm of shell.
Seen from the above description; the invention discloses a kind of seedling method for massively culturing of Tapes dorsatus; it includes the step such as indoor water mud sump larvae cultivation and the extensive seedling fostering of outdoor earth pond of Tapes dorsatus; to overcome in conventional chamber cement pit juvenile mollusk cultivate complex operation, need frequent fall pond, cause seedling to damage, impact kind of shoot survival percent and cannot the shortcoming such as large-scale industrialized production; establish seedling method for massively culturing, achieve seedling large-scale production.
