Description
Technical field
The utility model relates to a kind of viscid egg artificial fish nest that is applicable to Three Gorges Reservoir.
Background technology
After the retaining of Three Gorges, the two sides, reservoir area form large-area falling zone.Multiple pollutant in the falling zone enters water body when going up by rainwash or reservoir level, make each section of Three Gorges Reservoir, tributary body eutrophication in various degree occur, cause Measures of Algae in Water Body content sharply to rise, and water plants quantity sharply reduces, and then makes in the reservoir area take carp, crucian carp, sticks up mouth Culter, yellow cartfish etc. as the spawning place wretched insufficiency of main product viscid egg fish.Simultaneously, because the spawning season reservoir water level constantly descends, phytal zone pasture and water few in number are constantly surfaced, and have more aggravated this present situation, and the reproduction rate and the population quantity that cause producing the viscid egg fish are on a declining curve.Throw in artificial fish nest and can effectively improve this situation, yet the adhering substrate of artificial fish nest in the past all adopts chemical synthetic material, is unfavorable for environmental protection, can not solve the problem of laying eggs of fish of laying eggs of nesting such as yellow cartfish simultaneously.Therefore in order to improve the egg-laying environment of various product viscid egg fish in the reservoir area; enlarge population breeding scale; recover the fish natural resources; preserve the ecological environment simultaneously; now propose a kind of be applicable to Three Gorges Reservoir, natural plants as main, do not introduced the difficult degradation material, is taken into account the floating type artificial fish nest of fish of laying eggs of nesting simultaneously in the reservoir area.There is no at present this type of artificial fish nest.
Summary of the invention
The utility model purpose is for water body appearance eutrophication in various degree in Three Gorges Reservoir, produce the serious deficient present situation in spawning place of viscid egg fish, provide a kind of cheap, nonpollution material, the viscid egg artificial fish nest that can fluctuate with SEA LEVEL VARIATION.
The utility model for achieving the above object, adopt following technical scheme: described a kind of viscid egg artificial fish nest that is applicable to Three Gorges Reservoir comprises floating frame and spud pile, floating frame is fixed on spud pile by hawser, be with many group adhering substrates below floating frame, it is characterized in that: every group of adhering substrate is comprised of static line and the multi beam adhering substrate that is fixed on static line, every group of adhering substrate is fixed on the floating frame below by static line, fixes bottom an opened type that adhering substrate and water the is housed container of nesting at every static line.
The further technical scheme of the utility model: the every bundle adhering substrate on described static line is to be tied up by many strains reservoir area of Three Gorges dominant plant Bermuda grass to form, and the place's of tying up diameter of every bundle adhering substrate is 15-25cm, and two ends are puffy; Adhering substrate in the described container of nesting is to be formed by many strains reservoir area of Three Gorges dominant plant Bermuda grass tiling.
The further technical scheme of the utility model: described floating frame is to be tied up by many mao bamboons to form, the every long 5-10m of mao bamboon, three one rows, every spacing 1m, be that 6 groups of adhering substrates are arranged on every mao bamboon, two groups of adjacent adhering substrates be spaced apart 1m, every group of adhering substrate has two bundles, it is spaced apart 30-50cm.
Optimal technical solution of the present utility model: the described container of nesting is the jar of the wide-mouth of high 45-55cm, and its altar mouth diameter is 20-25cm, and the distance on nest container and static line between a branch of adhering substrate of foot is 30-50cm.
Optimal technical solution of the present utility model: the adhering substrate that is fixed on the top on every static line of described floating frame does not have the height of upstream face fully.
the utility model in the reservoir area of Three Gorges dominant plant Bermuda grass as adhesion material, replaced artificial difficult degradation material, draw materials conveniently, cheap, not perishable, nontoxic pollution-free, and should grass also have no by grass carp and take food, the jar that hangs over the bottom has the fish of the habit of nesting that the spawning place is provided for yellow cartfish etc., and has an effect of sinker, artificial fish nest described in the utility model is simple in structure, can fluctuate with SEA LEVEL VARIATION and can be carp in the reservoir area of Three Gorges, crucian carp effectively provides a large amount of spawning places with fish such as sticking up mouth Culter, can adhere to a large amount of fertilized eggs on the egg-laying period adhering substrate, help to protect and recover fishery resources in the reservoir area of Three Gorges, its effect is remarkable.
