Description
Technical field
The invention belongs to the technical field that fish spawning ground is repaired, particularly relate to a kind of tidal waters fish-egg attaching substratum fixture and the method for sampling.
Background technology
In recent years, due to impacts such as mankind's activity, water pollution and engineering constructions, the habitat that waters, entrance of Changjiang River aquatile depends on for existence is lost gradually, and hydrobiological spawning ground is seriously damaged, and causes the supplementary of fishery resources to be had a strong impact on.At present, in order to change this situation, carry out the research work of multinomial restoration of the ecosystem gradually, it is exactly the most directly wherein repair and reconstruction fish spawning ground, perch for fish provide good, ingest and spawning place, and provide good attaching substratum for fertilized egg, simultaneously further for the larva and juvenile of hatching provides sheltered situation.In addition, in the repair process of spawning ground, effect attaching substratum being adhered to fertilized egg is needed to carry out periodic sampling assessment.But at present when carrying out spawning ground to open waters such as entrances of Changjiang River and repairing, also do not have a kind ofly to be suitable for tidal fluctuations and to be conducive to operator carrying out sampling the attaching substratum fixture of assessment and the method for sampling to the adhesiving effect of fertilized egg.In fish-egg attaching device in the past, one end of attaching substratum is free, and free-end often swims in the surface of water body, does not reach the effect of reparation; Especially, when entrance of Changjiang River open water runs into stormy waves, the free-end of attaching substratum can be blown and beaten above water float body by stormy waves, loses its repairing effect completely.In other fish-egg attaching devices, buoyancy aid is cubical frame structure, and the two ends of attaching substratum are all fixed, and during ebb tide, whole frame structure can surface, and attaching substratum is also thereupon ineffective.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of tidal waters fish-egg attaching substratum fixture, and attaching substratum can stably float in water body, avoids attaching substratum to be exposed to more than the water surface.
The technical solution adopted for the present invention to solve the technical problems is to provide a kind of tidal waters fish-egg attaching substratum fixture, comprise buoyancy aid, some floating drums, steel pipe, some retainer rings, rope and attaching substratum, described buoyancy aid is self-floating rectangular flat plate structure, described buoyancy aid surrounding adopts steel framework to fix, described some floating drums are fixed on above buoyancy aid, described steel pipe correspondence is arranged at immediately below steel framework, described some retainer ring correspondences are fixed on steel pipe and steel framework, described rope is through two corresponding up and down retainer rings, to turn back up and down formation circulus, described rope full extension between two corresponding up and down retainer rings, unnecessary epimere ties up on retainer ring, one of two sections of ropes between two retainer rings of described upper and lower correspondence are fixed with some attaching substratums.
As one of the present invention preferred embodiment, the floating bed structure that described buoyancy aid is made up of bamboo chip, mesh sheet and water plants root system, surrounding is fixed by steel framework.
As another preferred embodiment of the present invention, described some floating drums are four, are individually fixed in the corner location of buoyancy aid.
As another preferred embodiment of the present invention, described floating drum adopts cylinder foam to make.
As another preferred embodiment of the present invention, two corresponding sides of the corresponding steel framework of described steel pipe are set to parallel two.
As another preferred embodiment of the present invention, described retainer ring is circular steel loop, is fixed on steel pipe and steel framework by the mode of welding.
As another preferred embodiment of the present invention, described buoyancy aid is square plate structure.
Another technical problem to be solved by this invention is to provide a kind of method of sampling of tidal waters fish-egg attaching substratum fixture, and simple to operate, sampling efficiency is high.
The present invention solves the method for sampling that technical scheme that this technical problem adopts is to provide a kind of tidal waters fish-egg attaching substratum fixture, comprises the following steps:
(1) the unnecessary epimere of rope is untied from upper retainer ring;
(2) be fixed with the side of attaching substratum by rope rope on the unnecessary epimere of rope, by the circulation of rope, opposite side declines thereupon;
(3), after attaching substratum is suggested, the adhesion fertilized egg on attaching substratum is sampled;
(4) backward haulage rope, attaching substratum comes back in water, regulates the position of attaching substratum to make it be between upper and lower paired retainer ring;
(5) rope and upper retainer ring are fastened again.
Beneficial effect
The buoyancy aid of attaching substratum fixture of the present invention is self-floating slab construction, swims on the water surface and can perch and sheltered situation for fish provide, contribute to fish and lay eggs at this; The buoyancy that the floating drum that buoyancy aid is installed and buoyancy aid self produce just in time balances each other with the gravity of lower square steel tube, thus keeps the balance of attaching substratum in whole device; Attaching substratum is connected with the steel framework of buoyancy aid surrounding by rope upper end, lower end and fastener for connection, at the incoming tide can by the effect of steel pipe gravity, avoid the lower end of attaching substratum too free and drift with the tide, ensure the vertical stretching of attaching substratum in water body, during ebb tide, buoyancy aid declines with the water surface, and attaching substratum remains in water body along with bending continuation of rope, thus avoids attaching substratum and be exposed to outside water body and lost efficacy.
The rope of this fixture is formation circulus of turning back up and down, there is one section of free segment in upper end, can be gathered the fertilized egg on attaching substratum quickly and easily by free segment, therefore the method for sampling of the present invention is simple to operate, is conducive to improving sampling efficiency.
