Abstract

The invention relates to a mussel artificial culturing method and belongs to the technical field of aquatic culturing methods. The mussel artificial culturing method comprises the following steps of (1) collecting and culturing mussel seedlings, (2) culturing the mussel seedlings in a deep water buoyant raft with a water depth of 2.5 to 5 m, and (3) harvesting and processing. When mussel seedlings grow to more than 10cm, a cable on the buoyant raft can be untied and the mussel seedlings can be directly harvested. In regarding to mussel growth features, an umbrella type seedling collection way and a deep water buoyant raft culturing method are employed, so commercial mussel harvesting rate can be improved and economic benefit is higher than general culturing methods.

Description

A kind of mussel artificial cultivating method

Technical field

The present invention relates to a kind of mussel artificial cultivating method, belong to aquaculture method and technology field.

Background technology

Mussel is worldwide cultivated shellfish, is the cultivation object that economic worth is higher, and be also the principal item of development mariculture, China coast has more than 30 kind of mussel, and the mussel propagated artificially at present mainly contains Mytilus galloprovincialis, Trachyostracous mussel and Perna viridis etc.Mussel is slightly raw easily to be supported, and delicious meat is nutritious, quite by consumers.Cultivation and the quality becoming the cultivation of shellfish to be directly connected to mussel of mussel seedling, artificial culture goes out physique stalwartness, resistance against diseases seed that is strong, fast growth can improve the success rate of mussel culture greatly, the nutrition being supplied to mussel seedling then directly affects the growth of mussel, the poor growth of currently used cultural method mussel, affects culturing economic income.

Summary of the invention

The object of the invention is to the deficiency solving the existence of above-mentioned prior art, a kind of scientific and reasonable mussel artificial cultivating method is provided.

The present invention is achieved through the following technical solutions:

A kind of mussel artificial cultivating method, its special feature is to comprise the following steps:

1) spat collection and Cultivating techniques: naturally collect seedling in sea area, fishes for the young by plankton tulle fixed point, selects the long spat for 380-400 micron of shell;

To collect seedling method: umbrella type is collected seedling, and namely use insertion seabed, a wood one end, the other end fastens many cables, scatters radially to surrounding, and the cable other end ties up on the timber of wood surrounding, cable requires to be uniformly distributed, and will strain simultaneously, is convenient to spat attachment;

2) form method: through the spat of 50-80 days apposition growths, general body reaches 0.5-1 centimetre, namely enters the cultivation stage of commodity shellfish.Method of forming adopts deep water suspended longline farming, and select depth of water 2.5-5 rice, trend is unimpeded, and flow velocity is slow, and stormy waves is less, and sea water specific gravity, in the sea area of 1.010-1.025, carries out hanging culture at time of low water erection buoyant raft, floating mat.Hanging culture district General Requirements water quality is more fertile, and plankton is enriched, and substrate mud is rocky few, and harmful organisms is less.Be barricaded as row's (or raft) with bamboo and wood, row's (raft) corner Plastic Drum makes float, is fixed with hawser and timber, so under the hawser that existing seedling adheres to is moved and is hung in buoyant raft or floating mat, each floating platform (raft) spacing is 5-7 rice, makes every effort to neat specification;

Mussel is formed in process, and one will carry out the work such as typhoon protection, anti-salinity adaptability, anti-red tide, waterproof pollution, and sea area tidewater be kept unimpeded, and seawater is not contaminated, reduces red tide and occurs; Two is that place periphery bamboo branch or old fishing net impale, and prevents conger pile, extra large , red crab etc. from entering in field, eats or endanger spat in case strive with spat; Three is prevent the little shellfish harm such as barnacle, in order to avoid contention hapteron and growing space, main method grasps seeding collecting season, avoids adhering to the Sheng phase with barnacle as far as possible and meet.Once generation red tide, preferably transplant seedlings and support his ground temporarily, if reached listing specification, gather in the crops listing.

3) results and processing: when mussel body reaches more than 10 centimetres, shellfish meat grossness, gathers in the crops when between May in annual December to next year, weather is felt nice and cool, and buoyant raft floating mat can Directly solution hawser results.

This method is the growth characteristic for mussel, and adopt umbrella type to collect seedling, deep water suspended longline farming mode, commodity shellfish utilization percent is higher, and the more general cultural method of income is high.

Embodiment

Below provide the specific embodiment of the present invention, be used for being further described formation of the present invention.

Embodiment 1

The mussel artificial cultivating method of the present embodiment, comprises the following steps:

1) spat collection and Cultivating techniques: naturally collect seedling in sea area, fishes for the young by plankton tulle fixed point, selects the long spat for 380-400 micron of shell;

To collect seedling method: umbrella type is collected seedling, and namely use insertion seabed, a wood one end, the other end fastens many cables, scatters radially to surrounding, and the cable other end ties up on the timber of wood surrounding, cable requires to be uniformly distributed, and will strain simultaneously, is convenient to spat attachment;

2) form method: through the spat of 50-80 days apposition growths, general body reaches 0.5-1 centimetre, namely enters the cultivation stage of commodity shellfish.Method of forming adopts deep water suspended longline farming, and select depth of water 2.5-5 rice, trend is unimpeded, and flow velocity is slow, and stormy waves is less, and sea water specific gravity, in the sea area of 1.010-1.025, carries out hanging culture at time of low water erection buoyant raft, floating mat.Hanging culture district General Requirements water quality is more fertile, and plankton is enriched, and substrate mud is rocky few, and harmful organisms is less.Be barricaded as row's (or raft) with bamboo and wood, row's (raft) corner Plastic Drum makes float, is fixed with hawser and timber, so under the hawser that existing seedling adheres to is moved and is hung in buoyant raft or floating mat, each floating platform (raft) spacing is 5-7 rice, makes every effort to neat specification;

Mussel is formed in process, and one will carry out the work such as typhoon protection, anti-salinity adaptability, anti-red tide, waterproof pollution, and sea area tidewater be kept unimpeded, and seawater is not contaminated, reduces red tide and occurs; Two is that place periphery bamboo branch or old fishing net impale, and prevents conger pile, extra large , red crab etc. from entering in field, eats or endanger spat in case strive with spat; Three is prevent the little shellfish harm such as barnacle, in order to avoid contention hapteron and growing space, main method grasps seeding collecting season, avoids adhering to the Sheng phase with barnacle as far as possible and meet.Once generation red tide, preferably transplant seedlings and support his ground temporarily, if reached listing specification, gather in the crops listing.
