Abstract
Carp is concentrated in advance and lays eggs and gathering unit, be provided with some fish-egg collectors in the net cage that it has, each fish-egg collector has the framework of an annular, framework is furnished with some fish nests, the below of framework is provided with and connects ovum mesh sheet, connects ovum mesh sheet and is connected by cotton rope with between framework.The carp provided by the utility model concentrates lay eggs morning and gathering unit is placed in Cultivated water, parent population can be placed in net cage and carry out laying eggs and collecting.Compared with laying eggs in net cage to lay eggs with in former pond with batch parent population, lay eggs and can shift to an earlier date, parent population is in framework or when laying eggs in framework side, and the chance that ovum is attached on fish nest increases than conventional rod fish nest; The ovum do not adhered on fish nest can be fallen and connect in ovum mesh sheet or in net cage; Parent population is when net cage periphery is laid eggs, and ovum can be attached to net cage side or fall at the bottom of case.Therefore, the ovum collecting produced can reach close to all collecting.In addition, in net cage, the Gunther parent fish spawning time concentrates, and after Gunther parent fish spawning, transhipment is convenient, and injury rate is little.
Description
Technical field
The utility model relates to aquaculture device, and specifically a kind of carp is concentrated in advance and lays eggs and gathering unit.
Background technology
At present, the mode of the collection fish-egg adopted mating season carp is: use fish nest to collect, fish nest is that polyethylene is without joint mesh sheet, about 1.5 meters of long thin bamboos evenly fix several fish nests, according to temperature, water temperature and carp gonad development situation, when estimating to be about to lay eggs, in advance fish nest is put in parent population pond, during Gunther parent fish spawning, ovum is produced on fish nest.This tradition shortcoming that collection mode exists of laying eggs is: the Gunther parent fish spawning time is more late, and egg-laying time span is large, and lay eggs and do not concentrate, cause seedling-growing time disunity, seed size is irregular; Except on fish nest, ovum can be collected, the ovum dropped in water cannot be collected, and ovum collecting rate is very low, collection rate only about 30%; Parent population harvesting transfer difficulty is large.
Utility model content
The purpose of this utility model is to provide a kind of carp to concentrate in advance to lay eggs and gathering unit, and the parent population that this is laid eggs and gathering unit can realize the natural spawning such as carp, crucian is concentrated in advance and lays eggs, and fish-egg height can be made to collect.
For achieving the above object, the utility model adopts following scheme: carp is concentrated in advance and lays eggs and gathering unit, this device has a net cage, some fish-egg collectors are provided with in net cage, each fish-egg collector has the framework of an annular, on framework interval be furnished with some fish nests, the below of framework is provided with and connects ovum mesh sheet, connects ovum mesh sheet and is connected by cotton rope with between framework.
The carp provided by the utility model concentrates lay eggs morning and gathering unit is placed in Cultivated water, surfaced certain altitude in net cage top, framework swims on the water surface, connects the bottom that ovum mesh sheet is laid in net cage, parent population can be placed in net cage and carry out laying eggs and collecting.In net cage, parent population owing to being subject to the stimulation of new equipment, compared with laying eggs in net cage to lay eggs with in former pond with batch parent population, lay eggs and can shift to an earlier date 10-15 days, when parent population lays eggs in framework, ovum is shed to surrounding, and the chance that ovum is attached on fish nest increases by 75% than conventional rod fish nest; Parent population when laying eggs in framework side, the ovum do not adhered on fish nest can fall bottom connect in ovum mesh sheet or in net cage; Parent population does not lay eggs near framework and when net cage periphery is laid eggs, ovum can be attached to net cage side or fall at the bottom of case.Therefore, the ovum produced can all be collected.In addition, the Gunther parent fish spawning time in net cage concentrates, and after Gunther parent fish spawning, transhipment is convenient, and injury rate is little.
The utility model is rational in infrastructure, easy to use, and it can make the egg-laying time of parent population in advance, and collection rate and the egg-laying time that greatly can improve again fish-egg are concentrated, and it is applicable to the fish of the natural spawning such as carp, crucian.
Accompanying drawing explanation
The structural representation of Fig. 1 the utility model one embodiment and using state schematic diagram;
The vertical view of Fig. 2 Fig. 1.
Embodiment
The utility model is further illustrated below in conjunction with embodiment and use-case.
See Fig. 1, Fig. 2
The carp that the utility model provides is concentrated in advance and to lay eggs and gathering unit has a net cage 1, and be provided with some fish-egg collectors in net cage 1, fish-egg collector includes framework 3, fish nest 4 and connects ovum mesh sheet 6.The basic structure of fish-egg collector is: each fish-egg collector has the framework 3 of an annular, on the frame 3 interval be furnished with some fish nests 4, the below of framework is provided with and connects ovum mesh sheet 6, connects between ovum mesh sheet 6 with framework 3 and is connected by cotton rope 5.
In the present embodiment, net cage 1 is hexahedron, its surrounding and bottom lock, open topped.
In the present embodiment, framework 3 is circular, is fixed with float 2 on the frame 3, and fish nest 4 is flexible mesh sheet, and middle part and the framework 3 of fish nest 4 are fixed.
In the present embodiment, connect ovum mesh sheet 6 and be made up of the skeleton 6a of screen cloth 6b and rectangle, the periphery of screen cloth 6b is fixed on skeleton 6a.
The material of above-mentioned net cage 1 adopts common nylon to sieve beautiful net, mesh specification 30 order.Before use, net cage 1 soaks 15 days in advance, scratches to prevent fish-egg; In use, net cage 1 is fixed on the position of pond surrounding convenient operation.The material of said frame 3 adopts the pvc pipe of diameter 20 millimeters.The material of above-mentioned fish nest 4 be polyethylene without joint net, mesh specification 5 millimeters, shape is good with square.Above-mentioned skeleton 6a material therefor is the reinforcing bar of 6 millimeters.Above-mentioned screen cloth 6b material therefor is identical with net cage.
As a preferably embodiment of the present utility model, the length and width of net cage 1 is 5 meters, dark 2 meters; The external diameter of annular framework is 700 millimeters; Fish nest 4 is square, the length of side 600 millimeters; Connect ovum mesh sheet 6 for square, the length of side 1.2 meters.In net cage 1, the interior fish-egg collector 1 of placing of the scope of about 2 square metres overlaps.
From Fig. 1, Fig. 2, the carp that the utility model provides is concentrated and to lay eggs and gathering unit is placed in Cultivated water in use, and framework 3 swims on the water surface, connects the bottom that ovum mesh sheet 6 is laid in net cage 1.
