Abstract

The utility model discloses a river snail breeding device. The river snail breeding device is characterized in that a plastic foam floating ball is arranged above the breeding device, the lower portion of the plastic foam floating ball is connected with a supporting rod with the length of 30 cm, the lower portion of the supporting rod is inserted in a round wood fixation disc, and the diameter of the fixation disc is 20 cm; battens divergent all around are respectively nailed to the bottom of the fixation disc, the number of the battens is 6-12, the length of each batten is 60 cm-100 cm, straws are bundled outside each batten by a circle through a bundling rope, the ends of the straws are scattered outside the bundling ropes by 10 cm-20 cm, and a sinker manufactured by putting cobblestones in a polyethylene net bag is hung on the lower portion of the fixation disc. The river snail breeding device is floated on the upper portion of a water body due to the buoyancy force of the plastic foam floating ball, river snails adhere to the straws for breeding, small newly born river snails adhere to the straws for living, the defect that the river snails can not breed because the water level is too deep is overcome, the breeding amount of the river snails in a water area is increased, and the breeding range of the river nails is broadened.

Description

A kind of spiral shell multiplier (-icator)

Technical field

The utility model relates to fishery field, specifically a kind of spiral shell multiplier (-icator).

Background technology

Spiral shell is a kind of important zoobenthos in freshwater, not only there is edibility, or the feed of the aquatic livestocks such as black carp, river crab, leech is biological, because spiral shell breeding generally need to be bred in water bottom, in the darker waters of water level, water bottom environment is not suitable for spiral shell breeding, and the multiplication nursery of spiral shell is limited to.

Summary of the invention

For overcoming above-mentioned defect, the utility model has designed a kind of spiral shell multiplier (-icator).

Concrete scheme of the present utility model is, a kind of spiral shell multiplier (-icator), it is characterized in that, multiplier (-icator) top is plastic foam ball float, plastic foam ball float below connects a long support bar of 30 centimetres, wooden fixation disk is inserted in support bar below, fixation disk is circular, 20 centimetres of diameters, the fixation disk bottom batten that nail system is scattered to surrounding respectively, batten quantity 6-12 props up, every long 60-100 centimetre of batten, batten external application tie string is pricked a upper circle straw, straw end stays 10-20 centimetres to be dispersed in outside tie string, the sinker that the hanging of fixation disk bottom is made of the packed stone of polythene net.

Beneficial effect, use the utility model spiral shell multiplier (-icator), by the buoyancy of plastic foam ball float, make multiplier (-icator) float on water body top, spiral shell invests on straw and breeds, and new born little spiral shell invests on straw lives, and has avoided because water level is crossed the irreproducible drawback of the spiral shell of taking an advanced study, improve large waters spiral shell propagation quantity, expanded the scope of spiral shell propagation.

Accompanying drawing explanation

Fig. 1 is the utility model structure chart.

In figure: 1 plastic foam ball float, 2 support bars, 3 fixation disks, 4 straw, 5 battens, 6 tie strings, 7 sinkers.

Embodiment

Accompanying drawings the utility model, a kind of spiral shell multiplier (-icator), it is characterized in that, multiplier (-icator) top is plastic foam ball float 1, plastic foam ball float 1 below connects a long support bar of 30 centimetres 2, wooden fixation disk 3 is inserted in support bar 2 belows, fixation disk 3 is circular, 20 centimetres of diameters, the batten 5 that the fixation disk 3 bottoms system of following closely is respectively scattered to surrounding, batten 5 quantity 6-12 prop up, every long 60-100 centimetre of batten 5, batten 5 external application tie strings 6 are pricked a upper circle straw 4, straw 4 ends stay 10-20 centimetres to be dispersed in outside tie string 6, the sinker 7 that fixation disk 4 bottom hangings are made of the packed stone of polythene net, use the utility model spiral shell multiplier (-icator), by the buoyancy of plastic foam ball float 1, make multiplier (-icator) float on water body top, spiral shell invests on straw 4 and breeds, new born little spiral shell invests life on straw 4, avoided because water level is crossed the irreproducible drawback of the spiral shell of taking an advanced study, improved large waters spiral shell propagation quantity, expanded the scope of spiral shell propagation.

Claims

1. a spiral shell multiplier (-icator), it is characterized in that, multiplier (-icator) top is plastic foam ball float, plastic foam ball float below connects a long support bar of 30 centimetres, wooden fixation disk is inserted in support bar below, fixation disk is circular, 20 centimetres of diameters, the fixation disk bottom batten that nail system is scattered to surrounding respectively, batten quantity 6-12 props up, every long 60-100 centimetre of batten, and batten external application tie string is pricked a upper circle straw, straw end stays 10-20 centimetres to be dispersed in outside tie string, the sinker that the hanging of fixation disk bottom is made of the packed stone of polythene net.
