Description
Technical field
The invention belongs to technical field of aquaculture, and in particular to it is a kind of suitable for algae fish mixed breeding combined artificial reef and its
Application method.
Background technique
The sea-farming in China is achieving very big development nearly ten years, is that cultured output is more than fishery output in the world
Unique country.Ecological fishery can realize the breeding production of specific aquatile in specific fisheries water environment, and real
The producer, consumer in existing The Ecosystem of Fishery and the layered multi-stage energy conversion between analyst and substance circulation, are one
Lasting, stable, the efficient fish production mode of kind.In recent years, the theory and mode of ecological fishery have been obtained improving and constantly sent out
Exhibition, for aquaculture model, higher requirements are also raised.
Under different types of ecological fishery cultivating mode, on the one hand requires producing upper quality and quantity promotion, provide
Stable, healthy output；On the other hand it requires to be reduced as far as cultivation adverse effect caused by environment, realize sustainable
Development.The cultural technique of single kind relative maturity, wherein economical alga such as kelp, asparagus etc. fits surface dependency in China
Cultured area constantly expands, and is made that tremendous contribution for the remittance of China's carbon；(Xu Shi is flat for economic seawater fish such as Larimichthys crocea, snakeheaded fish
Rockfish), the specific gravity in China's mariculture industry such as yellow croaker (greenling) increasingly increases, and is the development of China's mariculture industry
Provide very high economic output.But in current breeding process, the case where single variety is excessively stored up, is generally existing how
Ecologic breeding is carried out by means of the different ecological position between multi items, sea-farming industry in China's is supported to be turned from scalar type to mass type
It is turned into the task of top priority.
Ecological functions of the algae in the ecosystem are powerful, are capable of providing stable primary productivity, while mentioning for fish
For sanctuary, sanctuary, spawning place, algae and fish raising together with high ecological significance in open water.Multi items,
Three-dimensional Eco-breeding pattern has exploration and is tasted during the sea-farmings such as pond culture, cage culture, raft culture
Examination.203040415 U of utility model patent CN discloses a kind of proliferation reefs raised together suitable for fish, ginseng, Bao Duoyuan.The sea
Treasure proliferation reefs includes reefs shell and the Bao ginseng proliferation reef for being loaded into reefs inner chamber bottom, and reefs shell is by terrace with edge frame-type
Pedestal and frame type reefs shell composition, are poured by armored concrete, and Bao ginseng proliferation reef is to be loaded into entire reefs inner chamber
The stone of bottom or other small-sized proliferation reefs.After entire precious marine product proliferation reefs is launched specified sea area smooth bottom, to reef
The seed for launching stichopus japonicus and Bao in vivo loves reef fish by natural luring, realizes the polynary aquaculture of algae Bao ginseng.This is practical new
Type reefs facility can be used for the polynary integrated cultures such as fish ginseng Bao, improves product yield and quality, is advantageously implemented habitat rehabilitation
With the comprehensive utilization in sea area.The patent carries out aquaculture mainly for the animalities precious marine product such as fish, Bao, ginseng, lacks to region sea
Marine algae resource required for foreign system stable equilibrium carries out resource supplement, exists and generates the hidden danger acutely disturbed to natural environment,
Especially Bao is violent to the intensity of feeding of marine algae resource, is easy to cause environmental degradation, the ecosystem unbalance, can not embody completely
The profound connotation of ecological aquaculture.
In the wind sheltering region on island periphery, general water body is tranquiler, smaller by wave disturbance, is conducive to nutrients
Matter accumulation provides material base for algal grown, while providing excellent protection place for love reef fish, simultaneously because lonely
Hang it is marine, it is less by the effect of human activity, become ecological fishery development quality region, development prospect is wide, but simultaneously
Requirements at the higher level are proposed to the support of core technology.Carry out at present based on fish, algae fish mixed breeding work it is less, especially exist
Increased in natural sea area with natural resources and ecological fishery development based on protecting is even more very little, main reason is that algae
Scientific transplant transplantation technique there are technology and facility difficult point, be badly in need of research and development the relevant technologies and solved with facility.
