Abstract
The invention provides an artemia cyst shelling method. The method comprises the following steps that 1, commercial artemia cysts are soaked with fresh water so that the cysts can sufficiently absorb water and swell; 2, the artemia cysts are separated and placed in a shelling solution containing trypsin, and the mixture is slowly stirred; 3, when it is observed that the color of the cysts gradually changes from brown to orange red, a terminating agent is added; 4, standing is carried out after inflation and stirring, and shelled cysts are separated out, simply washed with sea water and then can be used for hatching or direct feeding. The shelling method is a biological shelling method, adopted raw materials are all natural products, no chemical pollution is caused to the shelled cysts, no adverse influence is imposed on direct feeding or subsequent hatching, and the effect is stable.
Description
Technical field
The invention belongs to artemia cysts applied technical field, be specifically related to a kind of method of shelling of artemia cysts.
Background technology
Artemia is named again fairy shrimp, is universal small-sized shell-fish, moves in salt lake, the contour saltwater in saltern.Artemia cysts is the aquatic fry growing bait of high-quality, has important function in culture fishery.Artemia chorion is iron content lipoprotein, and fish and shrimp seedling cannot digest, therefore it is generally required to first hatch artemia larvae, then again using germling as bait feeding.Chorion and germling after hatching are not easily completely separated, easily cause part hatched germling outwell with chorion and loss or chorion searched for food together with germling and cause fish and shrimp seedling intestinal obstruction dead.Artemia cysts can directly be thrown something and fed after shelling, it is also possible to hatches germling.Owing to there is no chorion, it is possible to reduce energy expenditure during germling broken shell, be conducive to retaining more nutrition.In fish and shrimp nursery, the expense of artemia cysts often accounts for nursery 50%-70% cost.By the method shelled, it is possible to improve incubation rate and make artemia larvae retain more nutrition, the low-quality ovum that a large amount of incubation rate is low can also be utilized, reducing seedling cost simultaneously, nursery is significant.
Current artemia cysts shells and adopts chemical method more, namely dissolves chorion with sodium hypochlorite and sodium hydroxide solution, and after shelling, reaction cannot terminate immediately, it is necessary to the ovum that will shell is pulled cleaning out and removed chlorine residue, and in this process, the chlorine residue of solution continues, to shelling ovum effect, to damage bigger;In the process of shelling, solution temperature easily raises simultaneously, affects incubation rate, it is necessary to take cooling measure;Operating process is very big on incubation rate impact, and technique is unstable;And the chlorine residue of ovum surface is difficult to thorough removal, there is chlorine distinctive smell to affect aquatic seedling when throwing something and feeding and search for food, also tend to need to add phagostimulant.
Summary of the invention
The invention provides the technical scheme that a kind of artemia cysts bioanalysis shells, it is therefore intended that solve above-mentioned chemical method shell exist deficiency.
1., by commodity artemia cysts freshwater soaking 2-4 hour, air agitation, make the abundant imbibition of ovum;
2. isolate artemia cysts, be placed on 10 times of weight and shell in liquid, 60r/min stirring at temperature 30 DEG C;
3. shelling 0.5-5 hour time, the color observing ovum is gradually become orange red by brown, adds terminator;
4. air agitation 10 minutes, stand, and separate the ovum that shells after being layered, with namely can be used for hatching after seawater flushing or directly throwing something and feeding.
If fresh water used is tap water in said process, need to dechlorinate in advance, alleviate the damage to ovum.
The described liquid composition that shells is: trypsin 0.1%-2%, EDTA0.02%, all the other are fresh water.
Described terminator composition is: Semen sojae atricolor that trypsin weight is 10 times and raw soya-bean milk prepared by the water of 5 times of Semen sojae atricolor weight.
In order to obtain effect of better shelling, in step 3, the time of shelling is preferably 2-3 hour, and the artemia of different sources time of shelling is different;Trypsin amount in liquid of shelling is preferably 0.5%-1.2%.
Lipoprotein agent structure in shell is hydrolyzed and removes by trypsin, other a small amount of remaining insoluble component in violent air agitation process by the shear action of liquid from egg membrane sur-face peeling.Containing trypsin inhibitor in Semen sojae atricolor; including Kunitz class inhibitor and BowmanBirk class inhibitor, it is possible to tryptic activity in the liquid that suppresses rapidly to shell, protection egg membrane is not damaged; use with the form of raw soya-bean milk, not only simple can also reduce cost.
Compared with prior art, beneficial effects of the present invention:
The invention belongs to bioanalysis to shell, raw materials used be natural product, do not introduce chemical raw material, to the ovum that shells without chemical contamination, follow-up hatching or directly throw something and feed is had no adverse effects, reduce operation easier, and the effect stability that shells.
Detailed description of the invention
By the examples below the present invention is described in further detail, but the present invention is not limited to following embodiment.
Embodiment 1:
1., by 500 grams of artemia cysts freshwater soaking 3 hours, air agitation, make the abundant imbibition of ovum.If fresh water used is tap water, need to dechlorinate in advance, alleviate the damage to the ovum that shells.
2. isolate artemia cysts, be placed on 5 liters and shell in liquid, 60r/min stirring at temperature 30 DEG C.The liquid composition that shells is: trypsin 0.8%, EDTA0.02%.
3. shell time 2 h, when the color of ovum is gradually become orange red by brown, adds terminator.Terminator composition is: raw soya-bean milk prepared by 400 grams of Semen sojae atricolor and 2 kg of water, and soybean trypsin inhibitor therein can effectively suppress tryptic activity, stops its destruction to egg membrane.
4. being placed in bottom solution by pneumatic head, it is tumbling state that charge flow rate reaches solution, air agitation 10 minutes, stands, and after solution is layered, the ovum that will shell is separated, and namely can be used for hatching or directly throw something and feed after simply rinsing with sea water.It is suppressed activity because of pancreatin, and the calcium ions and magnesium ions in sea water also can suppress its activity, egg membrane cannot be caused damage after diluting then through sea water, artemia larvae and fish and shrimp seedling is all harmless, save the time being largely used to repeatedly clean and artificial.
Embodiment 2: difference is shelled the method impact on artemia ovum hatching
The artemia cysts adopting the place of production to be same batch of Shandong, in natural light irradiation, salinity 30 ‰, temperature 28 DEG C, brooding time 24h, and other consistent when, take two kinds of methods incubation rate at shelling rate corresponding to different disposal time and the ovum that shells accordingly, contrasting the method for the shelling two kinds different impact on artemia ovum hatching, result is as shown in table 1.Wherein: matched group is normal incubation, does not shell;Chemical method is sodium hypochlorite and sodium hydroxide coupling;The incubation rate of two kinds of methods of shelling is the egg hatching rate that shells.
The impact on artemia ovum hatching of the table 1 different disposal method
Using chemical method to shell in process, the incubation rate of the ovum that shells becomes negative correlation with shelling rate, and the time of shelling, more long then shelling rate was more high, and incubation rate is more low.Although the egg hatching rate that shells when shelling rate is low is higher than matched group, but substantial portion of ovum is now also had not shell, so the overall incubation rate of ovum improves less;When shelling completely, overall incubation rate is lower than normal incubation on the contrary.Employing the inventive method is shelled, action temperature and, to ovum damage little, the egg hatching rate that shells when shelling rate height is still higher, makes the overall incubation rate of ovum improve a lot, and directly throw something and feed or for hatching all suitable.
