Abstract

The invention discloses a pile type oyster breeding method which comprises the following steps: selecting a breeding field, inserting piles, namely, sharpening one end of a wood rod which is 3-4m long as a wood pile, wrapping the surface of the wood pile with plastic, winding with seedling clusters of 2-3.5m long, and finally, inserting the wood pile in a breeding area in a grid manner; breeding the oyster freely, namely, attaching 20-30 oyster seedlings of 10-20mm to each attachment piece; fixing attachment pieces to the long seedling clusters, and breeding the oyster in the density that 100-110 attachment pieces are fixed in each square meter of the breeding area, and harvesting the oyster. By adopting the pile type oyster breeding method, the survival rate can be high, the oyster breeding cost can be greatly lowered, and the economic benefits can be increased.

Description

Oyster stake formula cultural method

Technical field

The present invention relates to technical field of aquaculture, especially, it is related to a seed oyster stake formula cultural method.

Background technology

With developing rapidly of Chinese national economy and steadily improving of living standards of the people, consumer's dietary structure occurs Great variety, for seafood products, such as ocean fish, sea shrimp, the consumption ratio of seashell products greatly increase again.Due to demand not Disconnected growth, the demand that cannot meet daily life is fished in traditional fishery, and therefore, the cultivation of marine product has huge warp Ji benefit, then how to improve the quality of culturing marine products and yield is the technical problem that industry is worth studying.

Content of the invention

Present invention aim at providing a seed oyster stake formula cultural method, to improve quality and the yield of oyster culture, fall Low aquaculture cost.

For achieving the above object, the present invention provides a seed oyster stake formula cultural method, comprises the following steps:

Select farming site: select depth of water 1-5 rice, salinity is not less than 0.9%, temperature is minimum to be not less than 6 DEG C and not more than 32 DEG C, ph value 7.6-8.4, dissolved oxygen ＞ 5 mg/litre, the sea area of freshet injection nearby having abundance is as farming site；

Pitching pile: fined away as timber, timber Surface coating plastics using 3-4 rice long rod one end, be wound around the upper long seedling of 2-3.5 rice afterwards Timber is finally inserted in culturing area by string in latticed；

Put in a suitable place to breed: select the oyster seed of size 10-20 millimeter, in each attachment flaps, 20-30 oysterseed of attachment is individual；Attachment Piece is fixed on long seedling string, puts in a suitable place to breed by the density of the fixing 100-110 bar attachment flaps of every square metre of culturing area；When juvenile mollusk grows to During 5-10 millimeter, cultivated and enriched in bait, in the brackish water inner bay breeding environment of salinity 0.9%-1.5%, until juvenile mollusk life Length is to 50-55 millimeter；After the growth of young shellfish is more than 55 millimeters, it is placed on bait and enriches, salinity is the brackish water of 2%-2.5% Form in environment；When young shellfish grows to more than 10 centimetres, transfer them to and enrich with bait, salinity is the height of 2.5%-3% Fattened in salt environment, the time is 30-90 days；

Harvest: when average shell is up to more than 10 centimetres, when gross weight is more than 150 grams, harvested.

Further, the spacing between described two adjacent timbers is 100 centimetres.

The method have the advantages that

This oyster culture method large batch of can carry out oyster culture, and oyster turnover rate is few, and survival rate is high, substantially reduces oyster Aquaculture cost, increase economic efficiency.

Specific embodiment

Hereinafter embodiments of the invention are described in detail.

The preferred embodiments of the present invention provide a seed oyster stake formula cultural method, comprise the following steps:

Select farming site: select depth of water 1-5 rice, salinity is not less than 0.9%, temperature is minimum to be not less than 6 DEG C and not more than 32 DEG C, ph value 7.6-8.4, dissolved oxygen ＞ 5 mg/litre, the sea area of freshet injection nearby having abundance is as farming site；

Pitching pile: fined away as timber, timber Surface coating plastics using 3-4 rice long rod one end, be wound around the upper long seedling of 2-3.5 rice afterwards Timber is finally inserted in culturing area by string in latticed；

Put in a suitable place to breed: select the oyster seed of size 10-20 millimeter, in each attachment flaps, 20-30 oysterseed of attachment is individual；Attachment Piece is fixed on long seedling string, puts in a suitable place to breed by the density of the fixing 100-110 bar attachment flaps of every square metre of culturing area；When juvenile mollusk grows to During 5-10 millimeter, cultivated and enriched in bait, in the brackish water inner bay breeding environment of salinity 0.9%-1.5%, until juvenile mollusk life Length is to 50-55 millimeter；After the growth of young shellfish is more than 55 millimeters, it is placed on bait and enriches, salinity is the brackish water of 2%-2.5% Form in environment；When young shellfish grows to more than 10 centimetres, transfer them to and enrich with bait, salinity is the height of 2.5%-3% Fattened in salt environment, the time is 30-90 days；

Harvest: when average shell is up to more than 10 centimetres, when gross weight is more than 150 grams, harvested.

This oyster culture method large batch of can carry out oyster culture, and oyster turnover rate is few, and survival rate is high, substantially reduces The aquaculture cost of oyster, increases economic efficiency.

Preferably, the spacing between described two adjacent timbers is 100 centimetres.

The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention；Skill for this area For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, made any repair Change, equivalent, improvement etc., should be included within the scope of the present invention.
