Description
Technical field
The present invention relates to fresh water bivalves artificial breeding systems technology field, present invention relates especially to a kind of fresh water bivalves hook
The artificial screening system of Jie's larva host symptoms.
Background technology
Fresh water bivalves refers to Mollusca, Bivalvia, freshwater mussel purpose species, and they are most of with the special history of life：
In breeding period, male freshwater mussel drains into sperm in water body, and female freshwater mussel is delivered to sperm in suprabranchial chamber by drainage, and female freshwater mussel is again by mature egg
Son is also entered in suprabranchial chamber and is fertilized, and embryonated egg develops the hook Jie larva for maturation on the gill filament, and it is suitable that larva needs are colonized in
On the host symptoms gill filament, fin ray or skin, through of short duration Parasitic metamorphosis development into young freshwater mussel, so as to complete nature procreation.Mussel
Class can be divided into two kinds of main Types by hook Jie larva to the selective difference of host symptoms：The first kind is popularity parasitism type, such as
The species of Anodonta, anodonta woodiana pacifica can be colonized in including completing metamorphosis in multiple common fish bodies such as carp, bighead, grass carp
Development, but there is significant difference in the parasitic metamorphosis rate in different fish bodies；Equations of The Second Kind is obligatory parasitism type, only selectively colonizes in
In certain several or specific fish body, such as hydriopsis cumingii hook Jie larva can colonize in Pelteobagrus fulvidraco, grass carp etc., and carp, crucian are non-host
Fish；Cristaria plicata hook Jie larva can colonize in bighead, and carp, Pelteobagrus fulvidraco are non-host symptoms；And purple black wing freshwater mussel be have now been found that right
The selective bivalves the most single-minded of host symptoms, it can only colonize in.Additionally, host symptoms
Specification also has material impact to the parasitic metamorphosis rate of larva.
About 840 kinds of existing fresh water bivalves, in addition to Antarctic region, each area of the world is distributed, and is currently known host symptoms
The species 1/4 of information less than.Since nearly half a century, the mankind's activity such as construction of overfishing, power station, rivers is changed its course, is dug
Husky mining, chemical pollution, Alien species etc. cause heavy damage, whole world bivalves natural resources to the habitat of bivalves
There is decline by a relatively large margin, some species have become extinct or in imminent danger.
In IUCN endangered species Red Lists in 2015（www.redlist.org）In the 517 kinds of fresh water bivalves that lists,
There are 161 kinds in nearly danger or threatened level, account for the 31.1% of sum, there are 31 kinds to become extinct, still there are 89 kinds without statistics.China
Be the centre of origin of Asia Non-marine Bivalvess, have many endemic species and rareness species, it has been reported that fresh water bivalves have 42 kinds.Light
Water bivalves not only has important economic worth, plays an important role in aquatic ecosystem is stable.At present, to jib
The artificial breeding research of main several economic bivalves such as freshwater mussel, cristaria plicata, Lamprotula leai is more, and posts needed for most bivalves
Main fish information is still almost blank.The Changjiang river and Pearl River Delta bivalves Natural Population and genetic diversity are remarkably decreased, some species
Even endangered species, such as Fo Erli freshwater mussels, solenaia oliveivora, keel razor clam freshwater mussel and pearl oyster pearl freshwater mussel etc. are become.
It is to realize the crucial skill of fresh water bivalves artificial breeding and propagation protection to filter out suitable host symptoms species and specification
One of art.Existing screening technique mainly using siphonage daily from parasitic fish temporarily support bottom portion suction out hook Jie larva for coming off and
Abnormal young freshwater mussel, wastes time and energy, and due to causing larger stress reaction in operation to parasitic fish, and cultivation water is difficult to protect
Card, the parasitic fish death rate are high, and cause the screening effect of host symptoms with extremely inefficient.
Content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, there is provided a kind of simple structure, can collect automatically and post
