Embodiment 1

[0035] The influence of embodiment 1 temperature on growth, survival and reproduction of hippocampus broodstock inflated abdomen

[0036] Set up a breeding pond with a salinity of 30, a pH value of 8.0, a daily water change of 100%, a dissolved oxygen of 8mg / L, and an illumination of 2500lx. Set up nursery ponds, water temperature 17.0, salinity 30, pH value 8.0, daily water change 50%, dissolved oxygen 10mg / L, illuminance 1500lx.

[0037] The experiment set up 4 experimental groups with different breeding pond water temperature of 13°C, 16°C, 19°C, and 22°C. Tail males (20 pairs) were stocked in 0.5t plastic tanks; when the natural water temperature was lower than the water temperature required for the experiment, an electric heating rod was used to heat it, and when the natural water temperature was higher than the experimental water temperature, a refrigerator was used to cool it down.

[0038] The bait for broodstock is mainly frozen mysis shrimp, with a small amount of l...

Embodiment 2

[0050] Example 2 Effects of pairing methods and the number of broodstock on the reproduction of the hippocampus inflated

[0051] In the experiment, the ratio of the number of males and females was 1:1, 1.5:1, 2:1, 1:1.5, 1:2 and other 5 matching methods. The number of parent fish in each pairing method was different, and the 1:1 pairing method was set as 1 6 experimental groups such as ♀+1♂, 2♀+2♂, 4♀+4♂, 6♀+8♂, 10♀+10♂; 1.5:1 pairing mode set 3♀+2♂, 6♀+4 5 experimental groups such as ♂, 9♀+6♂, 12♀+8♂, 15♀+10♂; the 2:1 pairing method is set to 2♀+1♂, 4♀+2♂, 8♀+4♂, 12 6 experimental groups such as ♀+6♂, 16♀+8♂, 20♀+10♂; 1:1.5 pairing method set 2♀+3♂, 4♀+6♂, 6♀+9♂, 8♀+12 ♂, 10♀+15♂ and other 5 experimental groups; 1:2 pairing method set 1♀+2♂, 2♀+4♂, 4♀+8♂, 6♀+12♂, 8♀+16♂, 10 6 experimental groups such as ♀+20♂, each experimental group was set up with 3 parallels. The experimental fish were randomly distributed in the experimental tank according to the proportion and quanti...

Embodiment 3

[0061] Effects of Breeding Density on the Growth and Survival of Hippocampus inflated Seedlings

[0062] In the experiment, there were 7 different density groups of 0.125 tails / L, 0.25 tails / L, 0.5 tails / L, 1 tail / L, 1.5 tails / L, 2 tails / L and 2.5 tails / L, and 3 parallel groups were set for each group. The 1-day-old experimental hippocampus seedlings were randomly stocked in each experimental tank according to the number.

[0063] Seedlings were cultivated in natural seawater with sand filtration and micro-flow water. During the experiment, the natural water temperature was 17.25±2.97°C, and the daily water change was 50-100%. The number of deaths was checked and registered every day; the experiment period was 60 days.

[0064] Other operations are the same as in Example 1.

[0065] On the 30th day and the 60th day, 20 seahorses were randomly selected in parallel, the total length and body mass indicators were measured, and the number of fry was counted to calculate the survi...

Abstract

The invention provides a breeding and seedling raising method for hippocampus abdominalis which comprises the following steps: S1, a breeding pond and a seedling raising pond are arranged, and according to the breeding pond, the water temperature is 13.0-20.2 DEG C, the salinity is 30-32, the pH value is 7.8-8.4, the daily water change amount is 100%-300%, the dissolved oxygen is 5-10 mg/L, and the illuminance is 1000-5000 lx; according to the seedling raising pond, the water temperature is 14.0-20.2 DEG C, the salinity is 30-32, the pH value is 7.8-8.4, the daily water change amount is 50-100%, the dissolved oxygen is 5-10 mg/L, and the illuminance is 1000-5000 lx; S2, parent fishes are put into the breeding pond, wherein the female-male ratio is (1.5: 1)-(1: 1.5); opossum shrimps are fed once in the morning and afternoon every day, and living copepods are fed after the opossum shrimps are fed in the afternoon every day; S3, after the parent fishes lay fry, the fry are fished out and put into the seedling raising pond, and the breeding density is 0.125-0.5 per L; before the full length of the fry is 5 cm, live copepods are fed four times a day; the overall length of the fry is 5-8 cm, live copepods and frozen copepods are fed, and feeding is conducted three times a day; and after the total length is 8 cm, frozen opossum shrimps are fed twice a day. The method is high in hippocampus abdominalis breeding rate, high in fry breeding survival rate and high in fry growth speed.

Description

technical field [0001] The invention relates to a method for propagating and raising seedlings of an inflated hippocampus, belonging to the technical field of inflated hippocampus propagation. Background technique [0002] As an important traditional Chinese medicine, hippocampus has the title of "Southern Ginseng" in our country. With the development of experimental technology and industry, more and more detection methods have been used in scientific research, and some medicinal effects of hippocampus have been confirmed. In recent years, the changes in the marine ecological environment, the intensification of offshore pollution and the overfishing of humans have caused serious damage to the feeding, habitat and reproduction of seahorse populations. At present, the wild population of seahorses is endangered. The World Biological Conservation Organization has listed all known seahorses in Appendix II of the Convention on International Trade in Endangered Species of Wild Fau...
