Embodiment 1

[0031] The invention relates to a domestication method for increasing the propagation, release and capture rate of seahorse seedlings in the Bohai Sea area, which includes a strengthening stage and a domestication stage.

[0032] Intensive phase (30 days)

[0033] This strengthening phase includes the following steps:

[0034] (1) Eliminate inferior seedlings. Inferior seedlings generally have whitish body color, incomplete body, underdeveloped, deformed head, and short snout. Especially the abdomen is the most obvious, with a yolk sac, lying on the bottom of the pool, with extremely poor swimming ability, unable to grow up, and unable to grow up after release, it is more common in the hippocampus born for the first time or prematurely born under extreme conditions.

[0035] The delivery density in the reinforcement phase is:

[0036] age of hippocampus

0～10

10～20

20～30

after 30

density

5 tails / L

3 tails / 2L

5 tails / 3L

2 tails / 5L ...

Embodiment 2

[0050] A method for domesticating seahorses, comprising a domestication stage, the various indicators of the domestication stage are as follows:

[0051] (1) Seed stocking density is:

[0052] age of hippocampus

0～10

10～20

20～30

after 30

density

5 tails / L

3 tails / 2L

5 tails / 3L

2 tails / 5L

[0053] (2) The rotifer larvae were fed within 24 hours after the seahorse seedlings were born.

[0054] (3) Feeding Artemia fished out from the breeding sea area. The feeding density is as follows:

[0055] domestication time / d

0～5

5～10

10～15

bait density

3% of the total weight of seedlings to be domesticated

2% of the total weight of seedlings to be domesticated

1% of the total weight of seedlings to be domesticated

[0056] (5) After strengthening, the hippocampus was reared in a flow acclimation pond with slow water inflow and outflow, and the bottom of the acclimation pond was silt.

[0057] (6...

Embodiment 3

[0061] A method for domesticating seahorses. The newly born seahorses are directly released after 30 days of breeding. The various indicators of the breeding process are as follows:

[0062] (1) The breeding temperature is 26-29°C, and the temperature fluctuation of the water body should not exceed ±4°C. If the temperature fluctuation is too large, the young hippocampus will be stressed, which will affect the feeding of the hippocampus, and eventually lead to the death of the hippocampus due to nutritional diseases.

[0063] (2) The salinity of the cultured water is 22-30 per thousand. Under this salinity, the young hippocampus grows obviously and is not prone to diseases.

[0064] (3) Breeding density:

[0065] age of hippocampus

[0066] The stocking density of juvenile seahorses is an important factor affecting the survival rate of seahorses. If the stocking density is too high, it is necessary to increase the amount of water exchange, which will cause the hippoc...

Abstract

The invention aims to provide a domestication method for increasing the recapture rate of releasing proliferation hippocampus fingerlings in bohai sea. The method includes the two parts of hippocampusphysique enhancement and domestication before releasing proliferation, increases the survival rate of the releasing proliferation hippocampus fingerlings in the natural environment, and improves thebenefits of releasing proliferation.

Description

technical field [0001] The invention relates to a domestication method for increasing the proliferation, release and recapture rate of hippocampus seedlings in the Bohai sea area. Background technique [0002] The enhancement and release of marine biological resources is a management method to restore marine fishery resources and achieve sustainable fishery development by releasing fish, shrimp, crab and shellfish broodstock, artificially bred seedlings or temporary wild seedlings into specific waters. The implementation of marine biological resource enhancement and release is the most direct and fundamental measure to restore fishery resources. [0003] Hippocampus is a precious Chinese medicine with high economic value. It has medicinal functions such as strengthening the body, nourishing the kidney and strengthening yang, relaxing tendons and activating collaterals, reducing inflammation and pain, calming the nerves, relieving cough and asthma, etc. It is especially effec...
