Background technology
In recent years, due to influences such as mankind's activity, water pollution and engineering constructions, the Changjiang river Estuary Waters aquatile is rely life
The habitat deposited gradually is lost, and the spawning ground of aquatile is seriously damaged, and causes the supplement of fishery resources by serious shadow
It rings.Currently, in order to change this situation, the research work of multinomial restoration of the ecosystem is gradually carried out, wherein being exactly the most directly
Repair and reconstruction fish spawning ground, for fish provide it is good inhabit, ingest and spawning place, and provide for fertilized eggs good
Attaching substratum, while further the larva and juvenile to hatch provides sheltered situation.In addition, in the repair process of spawning ground, need pair
The effect that attaching substratum adheres to fertilized eggs carries out periodic sampling assessment.But spawning ground is being carried out to open waters such as entrances of Changjiang River at present
When reparation, being suitable for tidal fluctuations and be conducive to operator to be sampled assessment to the adhesiving effect of fertilized eggs there are no a kind of
Attaching substratum fixing device and the method for sampling.In previous fish-egg attachment device, one end of attaching substratum is free, is dissociated
End often swims in the surface of water body, and the effect of reparation is not achieved；When especially in entrance of Changjiang River, open water encounters stormy waves, attachment base
The free-end of matter can lose its repairing effect completely by the upper surface of stormy waves piping and druming to water float body.Adhere in other fish-eggs
In device, floating body is cubical frame structure, and the both ends of attaching substratum are fixed, and when ebb tide, entire frame structure can be exposed
The water surface, attaching substratum are also ineffective therewith.
Invention content
Technical problem to be solved by the invention is to provide a kind of tidal waters fish-egg attaching substratum fixing device, attachment bases
Matter can be floated on steadily in water body, and attaching substratum is avoided to be exposed to the water surface or more.
It is solid that the technical solution adopted by the present invention to solve the technical problems is to provide a kind of tidal waters fish-egg attaching substratum
Determine device, including floating body, several floating drums, steel pipe, several fixed rings, rope and attaching substratum, the floating body is that self-floating is rectangular
Shape slab construction, the floating body surrounding are fixed using steel pipe framework, and several floating drums are fixed on above floating body, the steel pipe pair
It should be set to the underface of steel pipe framework, several fixed ring correspondences are fixed on steel pipe and steel pipe framework, and the rope is worn
Cross up and down corresponding two fixed rings, turn back to form cyclic structure up and down, the rope upper and lower corresponding two fixed rings it
Between full extension, extra epimere tie up in fixed ring, one of two sections of ropes between corresponding two fixed rings up and down
It is fixed with several attaching substratums.
As a kind of preferred embodiment of the present invention, the floating body is made of bamboo chip, mesh sheet and water plant root system
Floating bed structure, surrounding fixed by steel pipe framework.
As another preferred embodiment of the present invention, several floating drums are four, are individually fixed in the four of floating body
Angle Position.
As another preferred embodiment of the present invention, the floating drum is made of cylinder foam.
As another preferred embodiment of the present invention, two corresponding sides that the steel pipe corresponds to steel pipe framework are set as
Parallel two.
As another preferred embodiment of the present invention, the fixed ring is round steel loop, solid by welding
It is scheduled on steel pipe and steel pipe framework.
As another preferred embodiment of the present invention, the floating body is square slab construction.
Another technical problem to be solved by this invention is to provide a kind of tidal waters fish-egg attaching substratum fixing device
The method of sampling, easy to operate, sampling efficiency is high.
The present invention solves technical solution used by this technical problem and is to provide a kind of tidal waters fish-egg attaching substratum
The method of sampling of fixing device, includes the following steps：
(1) the extra epimere of rope is unlocked from upper fixed ring；
(2) side of attaching substratum is fixed with by lifting rope rope on the extra epimere of rope, it is another by the cycle of rope
Side declines therewith；
(3) after attaching substratum is suggested, the adherency fertilized eggs on attaching substratum are sampled；
(4) backward haulage rope, attaching substratum come back in water, and the position for adjusting attaching substratum is above and below
Between pairs of fixed ring；
(5) rope and upper fixed ring are fastened again.
Advantageous effect
The floating body of attaching substratum fixing device of the present invention is self-floating slab construction, and swimming on the water surface can carry for fish
For inhabiting and sheltered situation, fish is contributed to lay eggs herein；The buoyancy that the floating drum and floating body itself installed on floating body generate is just
The good gravity with lower square steel tube balances each other, to keep balance of the attaching substratum in whole device；Attaching substratum passes through rope
Upper end is connect with the steel pipe framework of floating body surrounding, lower end and fastener for connection, can be avoided at the incoming tide by the effect of steel pipe gravity
The lower end of attaching substratum is excessively free and drifts with the tide, and ensures vertical stretching of the attaching substratum in water body, when ebb tide floating body with
The water surface declines, and attaching substratum is continually maintained in the bending of rope in water body, is exposed to water body so as to avoid attaching substratum
Except and fail.
The rope of this fixing device is to turn back to form cyclic structure up and down, and upper end passes through free segment there are one section of free segment
Quickly and easily the fertilized eggs on attaching substratum can be acquired, therefore the method for sampling of the present invention is easy to operate, favorably
In raising sampling efficiency.
