Abstract
The invention discloses a three-dimensional artificial fish nest with a floating frame for adhesive eggs. The three-dimensional artificial fish nest is characterized by comprising fixed piles and the floating frame, wherein the floating frame is fixed on the fixed piles via fixing cables, a plurality of cables suspended with sinkers are arranged below the floating frame, and a plurality of adhesion matrixes are uniformly bound on each cable. The three-dimensional artificial fish nest disclosed by the invention can imitate the roots of aquatic plants or trees needing to be well adhered by fertilized eggs, and provide an omni-directional and three-dimensional type batch development place for the fertilized eggs of fishes laying adhesive eggs. The three-dimensional artificial fish nest is simple in structure, as well as convenient to throw and detach; a floating-type structure is not easy to be influenced by the change of a water surface; the adhesion area of the fish eggs is larger, and the three-dimensional space of a water body is adequately utilized; and large-scale propagation conditions can be provided for artificial breeding for fishes laying adhesive eggs living in different water layers and resource enhancement for natural populations. The three-dimensional artificial fish nest is especially suitable for artificial breeding for fishes living in the middle layer and the low layer of the water body.
Description
Technical field
The present invention relates to the three-dimensional artificial fish nest of a kind of floating frame formula viscid egg.
Background technology
Inland waters in our rivers, lakes and reservoirs in the community structure of resident fishes usually dominate the lakes this advantage is more significant, producing sticky fish eggs and fish in the settlement of the majority, which Representative species are carp, crucian carp, alburnus so on.This type fish inhabit the different water layers of water body usually, and fertilized egg need adhere on the corings of water plants or trees and accomplish embryo development procedure during breeding.Along with the Chinese society rapid economic development; The injection of a large amount of xenobiotic pollutantss makes most inland lakes eutrophication in various degree occur; Algae content sharply rises in the water body; The lake is tending towards the algae typeization gradually, produces the sharply decline of water plants amount that the viscid egg fish are relied in the water body, and the breeding of relevant fish receives direct influence.In order to improve the breeding condition of producing the viscid egg fish fast; Enlarge population breeding scale; Increase the juvenile fish generating capacity, the natural resources of the relevant fish of protection propose a kind of three-dimensional artificial fish nest making of floating frame formula viscid egg, put-on method that is applicable to shallow lake, pond and small reservoir at present.Still there is not this type of artificial fish nest at present.
Summary of the invention
The present invention seeks to the algae typeization generally to occur to present China inland lake, the present situation that the water plants storage sharply descends in the water body, providing a kind of can provide comprehensive, three-dimensional batch to grow the artificial fish nest in place for the fertilized egg of producing the viscid egg fish.
The present invention adopts following technical scheme for realizing above-mentioned purpose:
The three-dimensional artificial fish nest of a kind of floating frame formula viscid egg, it is characterized in that: it comprises spud pile, floating frame; Said floating frame is fixed on the said spud pile through fixing hawser, and said floating frame below is provided with the hawser that many bobs have sinker, on the said every hawser evenly tying-up a plurality of adhering substrates are arranged.
It is further characterized in that: said floating frame is square RPUF framework, length, width, highly is respectively 10m, 10m, 0.2m, and the length of each sash and width are 1m on the framework, and the frame wall thickness is 5cm; Each unit framework comprises the square sash of 100 1m * 1m altogether, and it is the waterproof metal suspension ring of 3cm that each below, sash crosspoint embeds diameter, and each unit framework comprises 121 suspension ring altogether; 1 bob of each suspension ring suspension has the hawser of sinker, and cable length is that 10cm is as the criterion with distance of the dried up end of sinker.
Further: said adhering substrate uses soft nylon wire to tie up; Mesh is not more than 1cm; Every fluffy adhering substrate Breadth Maximum 50cm, maximum height 35cm keeps certain gap long-pending and prevent that fish-egg from interacting to increase adhesive surface as far as possible between the net sheet of every fluffy matrix.
The present invention can be good at imitating water plants that fertilized egg need adhere to or the coring of trees, grows the place for the fertilized egg of producing the viscid egg fish provides comprehensive, three-dimensional batch.Simple in structure; It is convenient to throw in, remove, and floating structure is difficult for being influenced by the water surface changes, and the fish-egg adhered area is bigger; And make full use of the water body solid space, can scale breeding condition be provided for artificial breeding and the natural population stock enhancement of the product viscid egg fish that inhabit different water layers.The Technique in Fishes that is particularly useful for inhabiting the middle lower floor of water body is bred.

Among the figure, 1, mao bamboon; 2, floating frame; 3, suspension ring; 4, adhering substrate; 5, sinker.
Embodiment
Like Fig. 1, the three-dimensional artificial fish nest of a kind of floating frame formula viscid egg shown in 2.
(1) release time:
Settled fishes was generally in the lake before April before mating season, and water temperature is no more than 15 ℃;
(2) throw in the zone:
The depth of water is between 1.0-3.0m, and water quality is better, and transparency is greater than 40cm;
(3) fish nest structure:
The fish nest is by 4 fixing four jiaos mao bamboon 1, fixedly hawser and floating frame 2 are formed; Mao bamboon 1 length is 4-6 rice; 4 mao bamboons 1 are 5m with the distance of floating frame 2 corners; Cable length should be slightly larger than the distance (5.5m) of mao bamboon 1 and floating frame 2 corners, to guarantee that floating frame 2 can fluctuate with the water surface when the water surface change, is unlikely to make adhering substrate 4 surface (Fig. 1);
(4) frame structure:
RPUF lengths of frame, width, highly be respectively 10m, 10m, 0.2m, the length of each sash and width are 1m on the framework, and the frame wall thickness is 5cm.Each unit framework comprises the square sash of 100 1m * 1m altogether, and it is the waterproof metal suspension ring 3 of 3cm that each below, sash crosspoint embeds diameter, and each unit framework comprises 121 suspension ring 3 altogether.1 bob of each suspension ring 3 suspension has the hawser of sinker 5, and cable length is that 10cm is as the criterion with the 5 dried up end of sinker distance.The even tying-up adhering substrate 4 that uses soft nylon wire to tie up to form on the hawser begins every 50cm tying-up one fluffy adhering substrate 4 (Fig. 2) from the water surface in vertical direction;
(5) adhering substrate structure:
The soft nylon wire of use as shown in Figure 3 is tied up, and mesh is not more than 1cm, every fluffy adhering substrate 4 Breadth Maximum 50cm, and maximum height 35cm should keep certain gap long-pending and prevent that fish-egg from interacting to increase adhesive surface as far as possible between the net sheet of every fluffy matrix.Calculate with the dark water body of 2.5m, but tying-up 5 fluffy adhering substrates on every hawser, and each frame-type fish nest altogether can tying-up 605 fluffy adhering substrates.
