CN106305534A - Culture method of single oysters - Google Patents

Abstract

The invention discloses a culture method of single oysters. The culture method comprises the following steps of selecting a culture site, and stocking; selecting young oysters with body length of 10 to 20mm, putting the young oysters into a net bag with meshes of 5mm, and culturing the young oysters in the culture site or a shrimp pond in a hanging manner; when the young oysters grow until the body lengths reach 40 to 50mm, obtaining single young oysters; then putting the single young oysters in scallop cages with the meshes of 10mm to obtain the single oysters. According to the culture method of the single oysters, the survival rate is high, the culture cost of the oysters is greatly reduced, and economic benefits are increased.

Description

Concha Ostreae monomer cultural method

Technical field

The present invention relates to technical field of aquaculture, especially, relate to a seed oyster monomer cultural method.

Background technology

Along 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 fishes, Penaeus seu panulirus, the consumption ratio of seashell products are heavily greatly increased.Due to demand not Breaking and increase, 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 the quality how improving culturing marine products is the technical problem that industry is worth research with yield.

Summary of the invention

Present invention aim at providing a seed oyster monomer 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 monomer cultural method, comprises the following steps:

Selecting farming site: selecting depth of water 15-20 rice, salinity is not less than 0.9%, temperature is minimum to be not less than 6 DEG C and the highest is less than 32 DEG C, pH value 7.6-8.4, dissolved oxygen ＞ 5 mg/litre, near have abundance freshet inject sea area as farming site；

Put in a suitable place to breed: using the spat of oyster of body long 10-20 millimeter, putting it into mesh is that 5 millimeters of mesh bag hanging cultures are farming site or shrimp In pond, when the spat of oyster grows to body long 40-50 millimeter, it is thus achieved that monomer oyster Seedling；Afterwards monomer oyster Seedling is put into mesh 10 milli The scallop of rice is raised in cages into；Before consumption Seedling body length 60 millimeters, cultivated the brackish water inner bay breeding environment in salinity 0.9%-1.5% In；When consumption Miao Tichang more than 60 millimeters after, be placed on bait enrich, salinity be 1.5%-2% brackish water environment in support Become；When consuming Miao Tichang and growing to more than 10 centimetres, transferring them to have bait and enrich, salinity is the high salt ring of 2.5%-3% Fattening in border, fattening time is 60 days.

Further, described spat of oyster body length is when the 10-20 millimeter stage, and each mesh bag puts 280 in a suitable place to breed；When spat of oyster body When body length grows to 40-50 millimeter, every layer of each scallop cage places 55；When spat of oyster body length grows to more than 10 centimetres, Every layer of each scallop cage places 10.

The method have the advantages that

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

Detailed description of the invention

Hereinafter embodiments of the invention are described in detail.

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

Selecting farming site: selecting depth of water 15-20 rice, salinity is not less than 0.9%, temperature is minimum to be not less than 6 DEG C and the highest is less than 32 DEG C, pH value 7.6-8.4, dissolved oxygen ＞ 5 mg/litre, near have abundance freshet inject sea area as farming site；

Put in a suitable place to breed: using the spat of oyster of body long 10-20 millimeter, putting it into mesh is that 5 millimeters of mesh bag hanging cultures are farming site or shrimp In pond, when the spat of oyster grows to body long 40-50 millimeter, it is thus achieved that monomer oyster Seedling；Afterwards monomer oyster Seedling is put into mesh 10 milli The scallop of rice is raised in cages into；Before consumption Seedling body length 60 millimeters, cultivated the brackish water inner bay breeding environment in salinity 0.9%-1.5% In；When consumption Miao Tichang more than 60 millimeters after, be placed on bait enrich, salinity be 1.5%-2% brackish water environment in support Become；When consuming Miao Tichang and growing to more than 10 centimetres, transferring them to have bait and enrich, salinity is the high salt ring of 2.5%-3% Fattening in border, fattening time is 60 days.

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

For ensure the spat of oyster normal growth, it is preferable that described spat of oyster body length when the 10-20 millimeter stage, each net Bag puts 280 in a suitable place to breed；When spat of oyster body body length grows to 40-50 millimeter, every layer of each scallop cage places 55；When spat of oyster body When length grows to more than 10 centimetres, every layer of each scallop cage places 10.

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, that is made any repaiies Change, equivalent, improvement etc., should be included within the scope of the present invention.

Claims (2)

1. a seed oyster monomer cultural method, it is characterised in that comprise the following steps:
