Description
Technical field
The utility model relates to arrive aquaculture field, and in particular to a kind of for bivalve shellfish seed intermediate rearing
Enclosed gas charging upper up-flow breeding apparatus.
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 can be high in field cultivating survival rate
Up to 85% or more.Therefore, how to improve juvenile mollusk after metamorphosis to the survival rate and growth rate for growing to the 3mm stage in juvenile mollusk
Between cultivate and be 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
