Description
Technical field
The present invention relates to aquaculture fields, and in particular to a kind of opening for bivalve shellfish seed intermediate rearing
Inflatable upper up-flow breeding apparatus and its breeding method.
Background technique
China possesses huge marine shellfish aquaculture industry, and shellfish culture is important a member of sea-farming industry, produces
The 80% of the China Liang Zhan sea-farming total output.Common the bivalve shellfish such as delicious flavours such as clam, oyster and scallop, nutrition is rich
Richness has important economic value.As artificial culture technology continues to develop, efficient industrial seedling rearing mode is by more
Attention, shellfish aquaculture become mariculture industry pith.
During bivalve shellfish industrial seedling rearing, the intermediate rearing of juvenile mollusk is a key technology.Studies have shown that shell is long
300-1000 μm of juvenile mollusk is lower than 10% in field cultivating survival rate, and the juvenile mollusk of the long 3mm of shell may be up in field cultivating survival rate
85% or more.Therefore, centre of the juvenile mollusk after metamorphosis to the survival rate and growth rate for growing to the 3mm stage to juvenile mollusk how is improved
Cultivation is of great significance.
The mode that traditional artificial breeding mostly uses greatly bottom of pond to educate without sand culture, juvenile mollusk accumulate in bottom of pond, this cultivation side
Formula has the shortcomings that slow growth, the death rate are high, bait utilization is low etc..With the development of technology in recent years, rises streaming system and open
Begin the intermediate rearing for being used for juvenile mollusk, flows through juvenile mollusk using vertical water flow from bottom to top, provides to juvenile mollusk endlessly new
Fresh seawater and bait substantially increase the survival rate and growth rate of juvenile mollusk, meanwhile, upper up-flow has easy to maintain, effective use
The advantages that breeding spaces, long service life and save the cost.Upper up-flow working principle such as Fig. 1 that the prior art uses, passes through
The high pressure of high water level enters water in tank, and water flow passes through juvenile mollusk from bottom to top, then directly exhausts, and reaches ascending water with this
Stream.Although the method can effectively improve juvenile mollusk survival rate and growth rate, but not recycling after water flow discharge, waste water significantly
Resource and food resource improve cultivation cost.
Chinese Patent Application No. CN2017207906095.4 discloses a kind of leech upper up-flow circulating water culture system, packet
Include pier and culture zone；Pier include in length and breadth intersect made of bracket, set on frame bottom buoyancy tank and be fixed on
The pedal of rack upper surface；Culture zone includes that rhone, plug-flow pump and several box for breeding, box for breeding are arranged on bracket, row
Sink is located between box for breeding, it is characterised in that: buoyancy tank is equipped with aeration aperture and gas bleeder valve；Box for breeding includes case side wall and metal
Netted bottom；The top of case side wall is equipped with first through hole；Corresponding with first through hole is offered on the side wall of rhone
Two through-holes are fixedly connected between first through hole and the second through-hole by outlet pipe；The lower part for draining groove sidewall is equipped with draining
Pipe is attached between drainpipe and plug-flow pump by threeway.This utility model is pumped using plug-flow so that external water automatically flows into
Into box for breeding, while the oxygen content being arranged in air pump increase water, although circulation that this system solves water flow in box for breeding are asked
Topic, makes the water flow moment in box for breeding be in flow regime, increases water oxygen level, but is promoted by plug-flow pump entire
The water of system recycles, and power consumption can then greatly increase.
In view of the above-mentioned problems of the prior art, the present invention provides a kind of for bivalve shellfish seed intermediate rearing
Open inflatable upper up-flow breeding apparatus and its breeding method are to overcome drawbacks described above.
Summary of the invention
