Description
Technical field
The present invention relates to fish early stage the Study on Resources equipment technical field, i.e., after a kind of sampling for fish early stage resource
Filtering screening device.
Background technique
Fish early stage resource investigation is an important means for carrying out ecology of fishes and fishery biology research, as
A kind of independent resource investigation of fish method is ground by the investigation to the fish for being in the early life history stage in natural water area
Study carefully, can not only calculate the quantity of reproductive population, but also provide approach for the prediction of magnitude of recruitment.Meanwhile it being obtained in investigation
Related fish reproduction habit, fish early stage habitat distribution, the data such as environmental demand during early development, for fishery
The breeding, cultivation and protection of resources of new varieties have the function of positive in production.
For example, carrying out the studies of the life histories of early stage resource for the fish influenced by the various engineerings such as Three Gorges Projects, especially
It is the research of its early life history stage ecological demand, is conducive to that suitable region, such as breeding area, forage area is selected to establish
Protection zone, the method that artificial propagation can also be carried out using relevant knowledge increase population quantity.
In the prior art, the acquisition of early stage resource is generally first screened out thinner silt with the sieve of 40 mesh and 60 mesh, is stayed
Under the preservation of mixture formaldehyde take back laboratory, then cleaned with clear water and carry out the processing of sample, it is traditional to the sample adopted back
Processing is that sample is directly poured into pallet, and clear water is added, and the biggish impurity of volume is chosen rear with regard to directly carrying out larva and juvenile and fish-egg
Qualitative or quantitative processing work.
However, this direct processing method has many defects, for needing qualitative analysis when being suitable only for part
Acquisition object processing, firstly, since impurity is more, many larva and juveniles and fish-egg are all embedded in impurity and need to stir searching, in sample
Situation more than product quantity is found out and classifies extremely time-consuming if you need to do quantitative analysis, larva and juvenile all in disk；Secondly, by covering
It is embedded in and is difficult to find out in all samples in impurity, or even omit the more sample of number sometimes, to the system of number and type
It is larger to count error；Finally, the sample that this method screens is easy to make preservation and the later period of larva and juvenile and fish-egg with impurity
Analysis be affected.
Therefore, how will screen to the larva and juvenile in quantitative Treatment, and can reduce to the greatest extent again faster
The error of quantity and type statistics, improves working efficiency, becomes those skilled in the art's important technological problems to be solved.
Summary of the invention
The purpose of the present invention with provide it is a kind of for fish early stage resource sampling after filtering screening device, using the mistake
