Description
Technical field
The utility model relates to a kind of fish and to lay eggs device, particularly relates to a kind of natural water area fish and to lay eggs device.
Background technology
Occurring in nature, fish lay eggs needs certain physico chemical factor (as veil, fish-egg attaching substratum etc.) and biotic factor (mainly referring to the food organisms needed for son, juvenile fish).But, in recent years because the reasons such as mankind's activity, climatic variation, engineering construction cause the fish spawning ground in natural water area to be all over the world seriously damaged, particularly outstanding is that natural water area Mesichthyes oviposition substrate is suffered to destroy and the decline of food organisms abundance, directly cause that fish population presents unification trend, diversity sharply declines, endangered species increases, directly have influence on waters fish population structure.In the face of this present situation, protection fish spawning ground, good device and the egg-laying environment of laying eggs is provided to seem particularly urgent for fish.At present, protection work in China fish spawning ground is only limitted to enter and avoid engineering construction to occupy the control measures such as fish spawning ground by the strict control polluted articles of environmental assessment.But the restoration and reconstruction aspect for impaired spawning ground yet there are no relevant report.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of natural water area fish and lays eggs device, can not only be fish, the fish particularly producing viscid egg provide lay eggs veil and fish-egg attaching substratum, and can increase this waters food organisms density, ensure the supply of newly hatched larvae bait.
The utility model solves technical scheme that its technical problem adopts and is to provide a kind of natural water area fish and lays eggs device, comprise casing, described casing is cuboid frame structure, described casing upper surface two relative edges are provided with some floating drums, article two, be provided with some supports be parallel to each other between relative edge, described casing lower surface is corresponding with upper surface is provided with some supports, on casing, the quantity of lower surface support is equal, position is corresponding, on described, lower carriage correspondence is fixed with some retainer rings, corresponding is upper, lower retainer ring connects the upper of fish-egg attaching substratum respectively, lower two ends, described casing upper surface four drift angle places are provided with anchor line.
Described floating drum is positioned on casing upper surface two relatively short sides.
Described casing and support are galvanized pipe or tube material.
Described casing is by directly welding or making by the mode of cross buckle fastening.
Described floating drum is cylinder, adopts foamed plastics to make.
Described retainer ring is metal ring.
Described support is with casing, be connected by the mode of welding between retainer ring with support.
Described fish-egg attaching substratum is palm sheet or the piece of sack.
Described fish-egg attaching substratum is contacted by rope and is connected with retainer ring.
Described anchor line adopts polyvinyl chloride to make, and length is more than the twice of waters maximum water depth.
Beneficial effect
The utility model is by arranging fish-egg attaching substratum simulation natural water area fish egg-laying environment at box house, lay eggs veil and fish-egg attaching substratum can not only be provided for fish, simultaneously, fish-egg attaching substratum also can provide habitat for numerous food organisms group, thus add the food organisms density in waters of laying eggs, ensure the bait supply of newly hatched larvae.This device is arranged on impaired native species to lay eggs waters, the object in restoration and reconstruction fish spawning ground can be reached.
Accompanying drawing explanation
Fig. 1 is schematic top plan view of the present utility model.
Fig. 2 is cross-sectional schematic of the present utility model.
Fig. 3 is conjuncted using state figure of the present utility model.
Embodiment
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
A kind of natural water area fish as depicted in figs. 1 and 2 lay eggs device, and comprise casing 1, floating drum 2, anchor line 3, support 4, retainer ring 5 and fish-egg attaching substratum 6, casing 1 is the frame structure of cuboid or square.
For a kind of rectangular box body 1, this casing 1 adopts diameter to be the galvanized pipe of 40-60mm or steel pipe by direct welding or makes by the mode of cross buckle fastening, and the height of casing 1 is advisable with 1.2-1.5m.
On two long limits that casing 1 upper surface is relative, cover has some floating drums 2, and quantity is advisable with 4-6, and floating drum 2 is cylindrical shape, adopts foamed plastics to make.
Two minor faces that casing 1 upper surface is relative with lower surface are fixed with some supports 4 be parallel to each other respectively, support 4 is parallel to the long limit of casing 1, upper surface is equal with support 4 quantity of lower surface and position is corresponding, support 4 adopts the galvanized pipe of diameter 20-30mm or steel pipe to make, be fixed on casing 1 by the mode of welding, the spacing of support 4 is 600-800mm.
Support 4 is fixed with some retainer rings 5, the position of the retainer ring 5 on upper and lower support 4 is corresponding, and retainer ring 5 is the metal ring of diameter about 10mm, is fixed on support 4 by the mode of welding.
Fish-egg attaching substratum 6 is palm sheet or the piece of sack, is contacted, and be connected on the retainer ring 5 of upper and lower corresponding by the PVC rope of diameter about 8mm.
Four drift angle places of casing 1 upper surface connect anchor line 3 respectively, and anchor line 3 is the PVC rope of diameter 16mm, and length is more than the twice of waters maximum water depth.
This natural water area fish device of laying eggs is installed and used as follows:
Device of laying eggs four is linked together by anchor line 3 in the mode of sphere of movements for the elephants shape, forms conjuncted case of laying eggs, as shown in Figure 3; Impaired waters, fish spawning ground is selected to throw in conjuncted case of laying eggs; Before conjuncted case of laying eggs is thrown in, first squeeze into conjuncted case of laying eggs with bamboo anchor and throw in 3 ~ 5m depths in the water-bed mud in waters, then by anchor line 3, conjuncted case of laying eggs is connected with bamboo anchor, plays the effect of fixing conjuncted case of laying eggs; Multiple conjuncted case space between each other of laying eggs is 5 ~ 8m, is beneficial to water body circulation and exchanges.
Due to more than 2 times that anchor line 3 length is the depth of water, conjuncted case of laying eggs fully can be waftd by the effect of floating drum 2 and float on the surface, and can with SEA LEVEL VARIATION automatic lifting.By dropping into the conjuncted case of laying eggs of many groups, can be fish and large-area habitat of laying eggs is provided, to lay eggs waters if this device to be arranged on impaired native species, the restoration and reconstruction in fish spawning ground can be realized.
