Abstract

The utility model relates to a vertical fish egg adherence bed for stick fish eggs, which comprises a bamboo pole (1), connection ropes (2), fish egg collectors (3) made of meshes, and sinkers (4); the vertical fish egg adherence bed is characterized in that the bamboo pole is made into a rectangular framework, the connection ropes are uniformly arranged on the bamboo pole, the connection ropes are respectively 35-45 cm and 20-30 cm in lengths, the long ropes and the short ropes are distributed at intervals, the lower ends of the connection ropes are connected with the sinkers wrapped by the meshes and the fish egg collectors cut and bonded by the polyethylene meshes, so as to form a vertical bed structure, the fish egg collectors are made by cutting the polyethylene meshes with 20-60 grid meshes, the meshes are cut into strip shapes with the width of 5-10cm and the length of 40-60cm, every 25-30 meshes form a bundle which is folded from the middle and tied so as to adhere more stick fish eggs. The vertical fish egg adherence bed has the benefits that the a great number of fish egg collectors are arranged on the adherence bed, the area for adhering the eggs is large, and the fish eggs can be produced in a centralized way in batches; the sources of the manufacture materials are wide, the cost is low, the adherence bed can be used repeatedly, and the incubation survival rate of fish fries is high.

Description

A kind of viscosity fish-egg solid attaches the ovum bed

Technical field

The utility model relates to fish reproduction and produces apparatus, and the viscosity fish-egg solid in especially a kind of fish production attaches the ovum bed.

Background technology

In traditional fishery breeding, for the fish that produce the viscosity fish-egg, generally adopt pasture and water, willow fibrous root, palm silk etc. as the fish-egg adherance, from result of use, that pasture and water exist is perishable, be not easy to sterilize, adhere to the many defectives of dirt, attaches the ovum weak effect; Though the willow fibrous root is comparatively durable, need through the specially treated measure, like boiling etc., and the fibrous root lazy weight, it is also relatively poor to attach the ovum effect, is not easy to large tracts of land use; Though it is better that the palm silk attaches the ovum effect, because in the form of sheets, need knit with connection cord, shape is unfixing, and it is difficult to make, and in transport process, is prone to friction and makes the ovum abscission, has reduced the adhesive rate and the incubation rate of fish-egg.Adhere to and the hatching of viscosity fish-egg becomes the key factor that viscosity fish-egg fish fry large-scale mass production is produced in restriction.

Summary of the invention

The purpose of the utility model is in order to overcome that existing fish nest is not suitable for the defective of large-scale production fry and a kind of viscosity fish-egg solid of providing attaches the ovum bed.

The utility model solves the technical scheme that its technical problem adopted: viscosity fish-egg solid is attached the ovum bed and comprises: fish nest, sinker that bamboo pole, connection cord, polythene net sheet are made; It is characterized in that bamboo pole rolls the rectangularity framework, some connection cords are set on the bamboo pole, the lower end of every connection cord is pricked and is tied up the fish nest that a polythene net sheet makes and the sinker of net sheet parcel.

4～6 on bamboo pole, diameter 2～5cm is divided into two kinds according to length, 2～4 long on bamboo pole, long 2～4m, 2 short on bamboo pole, long 1～1.5m, bamboo pole rolls horizontal " day " font, horizontal stroke " order " font or horizontal stroke " mouth " font rectangle.

Connection cord is the polyethylene material; Length has two kinds, and the distance of from the bamboo pole to the bundle, tiing up fish nest and sinker is respectively 35～45cm, 20～30cm, and the connection cord of different length is spaced apart on bamboo pole; In water body, form three-dimensional fish nest distribution, the spacing of connection cord on bamboo pole is 10～15cm.

The fish nest is that 20～60 order polyethylene cuttings are processed; Cutting becomes the strip of wide 5～10cm, long 40～60cm, and per 20～30 strip net sheets are a branch of, rectangular doubling; Bundle is tied up in the centre; Be connected with connection cord, utilize polythene net sheet self buoyancy in water, the two ends of strip net sheet are independently extended in the water body.

Tie up the bottom of netting sheet fish nest at each bundle, bundle is a sinker, and each sinker 40～60g can be cobblestone, the lead of polythene net sheet parcel, pricks and ties up in the lower end at fish nest jag position, through the gravity of sinker, makes the fish nest be suspended to water body.

The beneficial effect of the utility model is: the fish nest quantity that solid attaches the setting of ovum bed is many, and it is big to attach the ovum area, is fit to centralized production fry in enormous quantities; Making attaches the raw material of ovum bed originates extensively, and cost of manufacture is low; It is long service life to attach the ovum bed, can reuse after sterile-processed, practices thrift cost; Make simple in structurely, use easy to operate; It is big to attach ovum density, and the hatch fish roe rate is high.

Below in conjunction with accompanying drawing and specific embodiment invention is further specified.

Embodiment

Like Fig. 1, shown in Figure 2, the utility model viscosity fish-egg solid attaches fish nest (3), the sinker (4) that the ovum bed comprises that bamboo pole (1), connection cord (2), net sheet are made; Bamboo pole diameter 4cm, length is 3 of 2m, 2 of 1m, rolls horizontal " day " font rectangular frame; Evenly roll some connection cords on the bamboo pole, connection cord length is respectively 40cm and 25cm, and the length connection cord is spaced apart; The spacing of connection cord on bamboo pole is 10cm, and the lower end of every connection cord connects respectively at the fish nest of net sheet making and the sinker of net sheet parcel, and the fish nest is that bundle system forms 30 long strip net sheets of the wide 50cm of 5cm from the centre; Each sinker weight 40g; Make with net sheet parcel cobblestone, prick and tie up, attach the ovum bed and roll 75 in fish nest altogether in fish nest lower end.

As stated, adopt the bamboo pole of 4 long 3m, 2 long 1.5m, roll horizontal " order " font rectangular frame; Connection cord length is respectively 45cm, 30cm, fish nest netting length 60cm, connection cord spacing 15cm; Each sinker weight 60g attaches the ovum bed and rolls 90 in fish nest.
