Abstract
The invention discloses a method for inducing body color change of young hippocampuserectus. In the method, the 20-day-old young hippocampuserectus is induced under physical environmental factors, so that the body color of the young hippocampuserectus is changed from black to yellow or saffron yellow, the color can be kept for a long term, and the survival rate of the young hippocampuserectus can also be remarkably improved. The body color of the young hippocampuserectus is subjected to induced change by using the method disclosed by the invention, thus the market value of the living hippocampuserectus can be increased, and the commercial culture efficiency of the hippocampuserectus is favorably improved.
Description
Technical field
The present invention relates to the technical field of hippocampus cultivation, be specifically related to a kind of method of inducing young strain line hippocampus body colour to change.
Background technology
At present, there is no in the world the patent report that hippocampus health color is changed; Based on the hippocampus biological property, utilize scientific method to become yellow or orange colour for hippocampus health color by black, strain line hippocampus single tail commodity price in the world will improve 3 ~ 5 times.But regrettably, most research remains for the research of the factors such as the screening of breeding environment, bait and aquaculture management on strain line hippocampus reproductive efficiency and survival rate impact, and the environmental factor comprehensive effect and the behavioral ecology research that affects the variation of hippocampus body colour rarely have report.
Summary of the invention
Thereby the object of the invention is to change the problem that affects its market value according to the body colour that exists in the existing hippocampus cultivation, provide a kind of and can change the abductive approach that young strain line hippocampus body colour changes.
Above-mentioned purpose of the present invention is achieved by the following technical programs:
A kind of method of inducing young strain line hippocampus body colour to change comprises the steps:
(1) 1 ~ 20 day young strain line hippocampus after the cultivation hatching, the aquaculture water temperature is 24 ~ 26 ℃, intensity of illumination 1300 ~ 1700 Lux, light dark period is 24:0, adds green pasture and water in the Cultivation container, pasture and water can be the plastics artificial aquatic weeds; The halogen worm of throwing something and feeding is satiated with food and throws something and feeds, and ight soil and residual bait siphon every day are clean;
(2) be that the breeding water body temperature of 21 ~ 40 days strain line hippocampus changes 28 ~ 30 ℃ into age in days, intensity of illumination 2800 ~ 3200 Lux, light dark period are 16:8, and the green pasture and water in the Cultivation container change redness, yellow and three kinds of pasture and water of green into; The halogen worm of throwing something and feeding is satiated with food and throws something and feeds, and ight soil and residual bait siphon every day are clean;
(3) be that the breeding water body temperature of 41 ~ 60 days strain line hippocampus changes 24 ~ 26 ℃ into age in days, intensity of illumination 1700 ~ 2300 Lux, light dark period are 14:10, and the pasture and water in the Cultivation container do not change; Throw something and feed halogen worm and oppossum shrimp are satiated with food and throw something and feed, and ight soil and residual bait siphon every day are clean;
(4) be that the cultivation intensity of illumination of the strain line hippocampus after 61 days changes 1000 ~ 1500 Lux into age in days, light dark period is 14:10, and the pasture and water color in the Cultivation container is any; The oppossum shrimp of throwing something and feeding is satiated with food and throws something and feeds, and ight soil and residual bait siphon every day are clean, obtains yellow or saffron strain line hippocampus.
As a kind of preferred version, in the above-mentioned abductive approach, water temperature is 24 ~ 26 ℃ described in the step (1), and intensity of illumination 1300 ~ 1700 Lux, light dark period are 24:0, and the height of green pasture and water * wide is 40cm * 8cm; Described halogen worm is the halogen worm of strengthening 5h with high unsaturated fatty acid, and the density of throwing something and feeding is 3 ~ 6/ml, throws something and feeds every day 6 times.
As a kind of preferred version, in the above-mentioned abductive approach, water temperature is 28 ~ 30 ℃ described in the step (2), intensity of illumination 2800 ~ 3200 Lux, light dark period is 16:8, the height of redness, the yellow and green three kinds of pasture and water * wide 40cm * 8cm that is, ratios red, yellow and three kinds of pasture and water of green are 4:2:1; Described halogen worm is to use chlorella
Chlorella sppStrengthen 8 days halogen worm, the density of throwing something and feeding is 2 ~ 4/ml, throws something and feeds every day 4 times.
As a kind of preferred version, in the above-mentioned abductive approach, water temperature is 24 ~ 26 ℃ described in the step (3), and intensity of illumination 1700 ~ 2300 Lux, light dark period are 14:10, and described halogen worm and oppossum shrimp were strengthened 15 days with flat algae and chlorella with horse, threw something and fed every day 3 times.
As a kind of preferred version, in the above-mentioned abductive approach, light dark period is 14:10 described in the step (4), and described oppossum shrimp is thrown something and fed 3 times every day.
As a kind of preferred version, in the above-mentioned abductive approach, the salinity of described breeding water body is 33 ± 1.0 ‰, and the pH value is 7.7 ± 0.4, and dissolved oxygen is 6.5 ± 0.5 mg/L.
By above-mentioned comprehensive adjustment to the factors such as temperature, intensity of illumination, photoperiod, bait and artificial aquatic weed color in the hippocampus breeding process, this directly application technology can be significantly the young hippocampus of black body surface be become yellow or orange colour body surface; Simultaneously, significantly improved the survival rate (improving more than 13%) of young hippocampus.
Compared with prior art, the present invention has following beneficial effect:
After the inventive method is induced young strain line hippocampus, the body surface color of 80% multi-thread line hippocampus children hippocampus becomes yellow (the young hippocampus about 5% becomes the orange colour body surface) by original black, and the survival rate of hippocampus is also brought up to more than 83% by original 70%, therefore, the price of hippocampus own and hippocampus culture benefit have greatly been improved.
The inventive method is easy to operate, and controllability is strong, is fit to large-scale commercialization hippocampus cultivation.
