Abstract
A cynoglossus semilaevis early-phase sex determination device comprises a box body with an upward opening and is characterized in that waterproof illumination lamp tubes are paved at the bottom of the box body, a glass flat plate for separating the lamp tubes and water in the box body is arranged above the lamp tubes, a screen structure is paved above the glass flat plate, a plurality of supporting columns are arranged under the box body, and a water inlet and a water outlet are formed in the box body. By means of the cynoglossus semilaevis early-phase sex determination device, through observation of morphological characteristics and sexual gland shapes of cynoglossus semilaevis on the premise of not damaging cynoglossus semilaevis bodies, the sex of the cynoglossus semilaevis can be determined as early as possible.
Description
Technical field
The utility model relates to a kind of device of distinguishing fish sex, is specifically related to the device that a kind of Cynoglossus semilaevis early sex is identified, belongs to technical field of aquaculture.
Background technology
Cynoglossus semilaevis (Cynoglossus semilaevis Gunther) belongs to Pleuronectiformes, Cynoglossidae, tongue sole genus, a kind of large-scale demersal fishes in coastal waters of warm warm nature, the characteristics of the wide temperature of tool, wide salt and adaptation changeable environment condition, 14 ℃～24 ℃ of optimum water temperatures, suitable salt scope 14～33.Along with the obtained breakthrough of Cynoglossus semilaevis artificial breeding in recent years, it grows seedlings ripe with cultural technique, and has carried out the batch production cultivating large area, is also first artificial breed variety of China's sole class.Cynoglossus semilaevis has become the high-grade aquatic products on China's dining table, because its delicious flavour, mouthfeel are smooth, high, nutritious without fishy smell and peculiar smell, protein content, and is subject to liking of consumers in general.For aquaculture enterprise, the economic worth of Cynoglossus semilaevis is high, on market, can sell for the price of 320 yuan/kilogram.Success cultivates the Cynoglossus semilaevis of 10,000 1 kilogram of left and right, can realize more than 300 ten thousand yuan of the output values.And, under current industrial aquaculture condition, through the cultivation of 2 years, more than the body of Cynoglossus semilaevis length just can reach 50cm, body weight can reach more than 1 kilogram, economic benefit is very high.
But propagate process artificially current, even under same breeding environment and raising condition, female Cynoglossus semilaevis individuality is all will be far superior to male aspect growth rate or Individual Size.Some male Cynoglossus semilaevis individualities also can only have very little increase aspect body length and body weight after the cultivation of a year, and the increase that this has just caused aquaculture cost, reduced raiser's economic benefit.
Therefore, how in the breeding process of Cynoglossus semilaevis, as early as possible male to be screened and to reject out, increasing as early as possible the ratio of female Cynoglossus semilaevis in breeding process, for the benefit that improves cultivation, seeming very important.
Summary of the invention
The device that provides a kind of Cynoglossus semilaevis early sex to identify is provided the utility model purpose, to overcome the deficiencies in the prior art.
The device that a kind of Cynoglossus semilaevis early sex is identified comprises and it is characterized in that the box body of a upper opening being equipped with the waterproof, illuminating fluorescent tube above the box body bottom that the fluorescent tube top is provided with for sealing the glass plate of fluorescent tube.
Consider and place Cynoglossus semilaevis for the identification of early stage individual male and female sex, be equipped with screen structure above glass plate.
Consider easy to usely and for whole device provides effective support, above-mentioned box body below also is provided with a plurality of pillars.
Consider front water filling easy to use and use effective draining afterwards, above-mentioned box body also is provided with inlet opening and apopore.
In order to reduce the cost loss in the cynoglossus semilaevis cultivation process, the male and female of more early identifying Cynoglossus semilaevis are better, but when considering too early, the feature difference of male and female sex character and sexual gland is not obvious, determines when Cynoglossus semilaevis average weight 35～40 gram and tentatively selects.While selecting, adopt device of the present invention to carry out.During use, at first from inlet opening, in device, be filled with seawater, the seawater liquid level surpasses screen structure.The switch opens of fluorescent tube is controlled in the handle assembly below, after Cynoglossus semilaevis being pulled out from breeding water body come, is placed on screen structure.With a collection of Cynoglossus semilaevis, can distinguish by seeing size and length, from the external shape of fish, the health of raun is wide short, and the health of milter is long narrow, and the raun of same size is slightly wide shorter than milter.Through the irradiation of waterproof, illuminating fluorescent tube, by the sexual gland feature distinguish the differentiation male and female, what sexual gland was more elongated is male, the sexual gland tubbiness be female.
Utilize device of the present utility model to carry out the evaluation of Cynoglossus semilaevis male and female sex, by add seawater in device, Cynoglossus semilaevis can be put into to seawater and test, can not damage Cynoglossus semilaevis.The glass of illuminating lamp tube top can completely cut off seawater, makes the waterproof, illuminating fluorescent tube avoid seawater corrosion, and the phenomenon of electric leakage can not occur.After seawater is put in the space of glass top, for Cynoglossus semilaevis provides movable space, avoid it to come to harm because of dried up.Cynoglossus semilaevis is placed on the set screen structure in glass top, is convenient to effectively differentiate its male and female.Under the irradiation of illuminating lamp tube, be more conducive to observe the form of Cynoglossus semilaevis, also be convenient to by observing its sexual gland characterized male and female sex.The application of this device can in the situation that do not cause fish body damage, by observing morphological feature and the sexual gland shape of Cynoglossus semilaevis, be identified the sex of Cynoglossus semilaevis as early as possible.
