Description

Technical Field

[0001] The present invention relates to the technical field of seahorse breeding, and more specifically, to a seahorse ecological breeding method. Background Art

[0002] Seahorse is a traditional precious Chinese medicine in my country and is known as animal ginseng. In the current clear water aquaculture method, even if the aquaculture water is properly treated, it is difficult to completely eliminate the Vibrio carried by live bait during the aquaculture process. It is also difficult to control the number of Vibrio in the water using probiotics. The incidence of enteritis is still very high, especially in the first 20 days of aquaculture. Seahorses have weak resistance and are prone to enteritis. Therefore, controlling the amount of Vibrio in the aquaculture environment below the pathogenic threshold is the key to controlling enteritis. Circulating water optional aquaculture is one of the methods, but the cost is high. Due to the feeding of live bait, the effect of controlling Vibrio is not ideal. In addition, the puffy seahorse, also known as the big-bellied seahorse, is native to the southwestern Pacific Ocean, Oceania, and the waters near New Zealand. It is one of the largest species of all known seahorses and lives in reef areas with a depth of up to 100m. At present, the artificial breeding of puff-bellied seahorses is gradually being carried out, but the artificial breeding technology is still immature. Most of the current breeding technologies involve the three-shift seahorse, the Japanese seahorse and the gray seahorse (lined seahorse). The healthy breeding technology of the puff-bellied seahorse is still imperfect. Moreover, due to different geographical environmental conditions and water quality differences, the technology of artificial breeding of puff-bellied seahorses is different from that of other types of seahorses. Artificial breeding of puff-bellied seahorses faces low survival rates and disease threats. Summary of the invention

[0003] 1. Technical issues to be solved

[0004] In view of the problems existing in the prior art, the present invention provides a seahorse ecological breeding method to solve the technical problems mentioned in the background technology.

[0005] (II) Technical solution

[0006] To achieve the above object, the present invention provides the following technical solution: a method for ecological breeding of seahorses, comprising the following steps:

[0007] Step 1: Select a farm pond, limit the quality of water used in the farm, treat the water, add it to the breeding container, add 3-5ppm hydrogen peroxide silver ion liquid, and then put in the newborn gray seahorse seedlings. In addition, the pond is equipped with nano-inflatable tubes and materials for seahorses to climb on, and there is no need to set up cages; in the southern summer where the daily temperature is above 26 degrees for a long time, it is necessary to build a shed to cover the whole pond with a black net, and the light transmittance of the black net reaches 10,000-12,000 l ux at noon on a sunny day; the shed area shall not exceed 2 mu, and the pool depth shall be 2.5-3.0 meters;

[0008] Step 2: Add goldfish and horse snails into the culture pond, and pour in the treated shrimp slices every day. When the water turns brown, add seahorses for cultivation. For the first 20 days of breeding, change the water by 10-15% every day, and add 3-5ppm hydrogen peroxide silver ion solution every 2 days. After 20 days, keep changing the water by 10-15% every day, and treat with 6-8ppm hydrogen peroxide silver ion solution every 4 days. Except for the day when hydrogen peroxide silver ion solution is used, add EM bacteria every day.

[0009] Step 3: During the breeding period, the minimum water temperature is above 18℃, the daily water temperature difference is below 2.5℃, the fish are killed after the pond is filled with water, the water is fertilized to cultivate algae, the copepods per milliliter should be maintained at more than 0.5, and the transparency of the pond water is not higher than 70 cm;

[0010] Step 4: continue to cultivate the seahorses in the above steps until they are 9-10 cm, wherein the cultivation temperature is 21-23°C, and only mysid shrimp is fed during the cultivation process. The cultivation time is 3-4 weeks, and the seahorses are cultivated to 10-11 cm, which is the best harvesting specification. The gray seahorses of this specification have the highest selenium content, which can increase the selenium content of the gray seahorses by more than 2 times, and the specific selenium content is 6.43±0.06 mg·kg-1;

[0011] Step 5: Supplement with 0.4-0.7 cm Artemia every day, with a feeding density of 1-2 / ml, and feed 4 times a day. In addition to monitoring the physical and chemical indicators of water quality, microbial indicators need to be closely monitored.

[0012] The present invention is further configured that in the step 1, the culture temperature is 21-30° C., only copepods are fed before the hippocampus is 3.5 cm high, and then 0.4-0.7 cm Artemia is supplemented every day. After the hippocampus is 6 cm high, copepods + adult Artemia, frozen mysid shrimp, or frozen mysid shrimp + adult Artemia are fed.

[0013] The present invention is further configured such that the breeding pond is equipped with nano-inflatable tubes as follows: one nano-tube inflation ring is set for every 20-30 square meters, with a diameter of 20 centimeters, and the inflation ring is set at a water depth of 1.5 meters; and inflation is performed regularly for 30-60 minutes at 5:00-6:00 and 12:00-13:00 every day.

[0014] The present invention is further configured such that the aquaculture water must be sand filtered and then treated with an ultraviolet lamp.

[0015] The present invention is further configured such that the salinity of the aquaculture water is 33-36‰, and when the salinity is higher than 36‰, fresh water is supplemented to reduce the salinity to below 33‰.

[0016] The present invention is further configured that in the step 5, the content of Vibrio in the water is controlled below 300 cfu; when the Vibrio exceeds 1000 cfu, 1 ppm hydrogen peroxide silver ion liquid is used for continuous treatment for 2-3 days.

[0017] The present invention is further configured such that when the aquaculture water temperature is stabilized below 27 degrees, the hydrogen peroxide silver ion liquid is stopped.

[0018] The present invention is further configured such that the mysid shrimp is frozen or alive.

[0019] The present invention is further configured such that if the seahorses are sexually differentiated, the males and females are cultured separately.

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the present invention provides a method for ecological breeding of seahorses, which has the following beneficial effects:

[0022] The biggest feature of the present invention is that it takes into account both growth and active ingredient content. All measures in the early stage of breeding are mainly aimed at promoting growth. Therefore, it is sufficient to maintain the temperature within the suitable growth temperature range (i.e., 21-30°C) to ensure growth; to achieve the best harvest specification, taking into account body height-weight and active substance content, 10-11 cm is the best harvest specification, because our research found that the selenium content of gray seahorses of 10-11 cm is the highest, and the selenium content of seahorses above or below this specification is low; in addition, when the seahorses grow from 9-10 cm to 10-11 cm, the weight gain of the seahorses is significant), it is adjusted to a temperature that is conducive to the accumulation of active substances and ensures a certain growth rate (i.e., 21-23°C, the seahorses can be harvested at a temperature of 10-21°C). The content of trace element selenium in seahorses is increased by more than 2 times, which improves the value of seahorses. As can be seen from Table 1, mysid shrimp is the best bait to increase the selenium content; when the temperature is higher than 23 degrees, the selenium content is greatly reduced. In addition, the breeding method provided by the present invention selects domesticated healthy seahorse individuals as stable parents to breed seahorses, improves the environmental adaptability of breeding seahorses, controls reasonable breeding density according to different specifications of breeding seahorses, and artificially prolongs the light cycle, simplifies the feeding method of bait (fresh bait only uses easily available rotifers and Artemia), strengthens the nutrition of bait (strengthening with enhancers), and cleans up feces in time (1.5 to 2 hours after feeding), thereby reducing the water pollution and disease incidence rate of the breeding environment.
