Abstract
The utility model discloses a finless eel offspring seed selecting box. The finless eel offspring seed selecting box is mainly composed of a box body, a first elastic ring shaft type gauze element, a first pulling rope and a flashboard, wherein a water outlet is formed in the bottom of the box body; the first elastic ring shaft type gauze element is fixed on the inner side wall of the box body; a hole is formed in one side of the side wall of the box body, which is relative to the first elastic ring shaft type gauze element; one end of the first pulling rope and the free end are fixed outside the first elastic ring shaft type gauze element and the other end of the first pulling rope penetrates through the hole in the side wall of the box body to be located outside the box body. The finless eel offspring seed selecting box has the advantages that high-quality finless eels have strong physiques and are sunk in a water bottom layer; inferior finless eels have weak physiques and have no power to fight with the strong finless eels for a bottom layer hidden field so as to be enforced to float on a water surface layer; finless eel offspring seeds with different grades and weights are selected; the selection speed is fast, the selection accuracy is high and the manpower labor intensity is low; the finless eel offspring seed selecting box is good for normal and rapid development of a finless eel culture industry.
Description
Technical field
The utility model relates to the technical field of cultivation with instrument, more particularly relates to the technical field of culturing rice field eel with instrument.
Background technology
Swamp eel is commonly called as yellow eel, the life fish that dwell at the bottom of the fresh water for warm band, and its fine and tender taste, nutritious, can make multiple delicacies delicious food, as Fried eel in brown sauce sheet, oil slip the hall such as eel sheet, oily halogen eel pine and yellow eel chafing dish dish, welcome by the masses! The artificial propagation of swamp eel at present still can not get effective solution, and the swamp eel seed still relies on field to collect now, then by propagating the rear sale of growing up artificially.But, at present by artificial field, collect the swamp eel seed that returns for various reasons, the swamp eel seed of part exists certain internal injury or wound, both common said bad seeds of people, the phenomena of mortality just easily appear in this seed inferior in propagating process artificially, and if the swamp eel after death is not cleared the normal growth that will badly influence other swamp eel in time, therefore, must strictly pick out swamp eel seed inferior when being propagated artificially swamp eel, current selection method is mainly to rely on manually to select by rule of thumb, not only select speed slow, and can't accurately pick out real bad seed, thereby badly influenced the normal fast development of culture of swamp eel industry.
The utility model content
The purpose of this utility model provides a kind of speed of selecting fast in order to solve above-mentioned deficiency exactly, selects accuracy high, and hand labor intensity is low, is beneficial to the normal fast-developing swamp eel seed of culture of swamp eel industry and selects case.
The technical solution that the utility model adopts in order to solve the problems of the technologies described above is as follows:
The swamp eel seed selects case, it is mainly by casing, the first elastic ring shaft type gauze, the first pull rope and flashboard form, described casing is uncovered shape, bottom at this casing offers delivery port, be provided with the flashboard stopper slot at this water outlet, described flashboard is plugged in this flashboard stopper slot, described the first elastic ring shaft type gauze is fixed on the madial wall of casing, with on the wall box of the relative side of this first elastic ring shaft type gauze, offer porose, the outer free end of one end of described the first pull rope and the first elastic ring shaft type gauze fixes, the other end is positioned at outside casing through the hole on wall box.
It also includes the second elastic ring shaft type gauze and the second pull rope, described the second elastic ring shaft type gauze is fixedly mounted on the madial wall of casing, and be positioned at the downside of the first elastic ring shaft type gauze, with on the wall box of the relative side of this second elastic ring shaft type gauze, offer porose, the outer free end of one end of described the second pull rope and the second elastic ring shaft type gauze fixes, and the other end is positioned at outside casing through the hole on wall box.
Be provided with airtight and watertight padding in hole on described wall box.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: utilize the strong bottom layer that is sunken to of high-quality swamp eel physique, a little less than swamp eel physique inferior, swamp eel unable and strong shape fights for the bottom sheltered situation, and be forced to float on the characteristic of layer waterborne, first the swamp eel seed is poured in the casing of filling water, Deng about 20 minutes time, after the activity of swamp eel seed is stable, by pull rope, elastic ring shaft type gauze is extended, two-layer up and down by being divided in casing, upper strata is swamp eel seed inferior, lower floor is high-quality swamp eel seed, finally extract flashboard out, allow the high-quality swamp eel seed of lower floor flow out with water, the upper strata leached swamp eel seed inferior can use the same method again and carry out the work of selecting that primary screening can finally complete the swamp eel seed, it is the swamp eel seed needs of selecting different stage and quality in order to adapt to that the utility model arranges two-layer elastic ring shaft type gauze, select speed fast, select accuracy high, hand labor intensity is low, be beneficial to the culture of swamp eel industry normally fast-developing.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
