Description

Technical Field

[0001] The present invention relates to the technical field of seahorse breeding, and in particular to an intensive seahorse breeding method. Background Art

[0002] The seahorse (Hippocampus sp.) is both a seafood and a valuable traditional Chinese medicinal herb, known as the "ginseng of the South." It also holds considerable ornamental value. It is generally found in tropical and subtropical regions, along my country's coastal areas. The main cultivated seahorse species in my country are the spotted seahorse (Hippocampus trimaculatus Leach), the large seahorse (H. kudableeker), and the lined seahorse (H. kelloggi Jorden et Snyder). Although the seahorse's appearance differs significantly from commonly encountered fish, its physiological structure clearly shares fish characteristics: it breathes with gills, possesses a backbone, and possesses dorsal, pectoral, and anal fins. Therefore, biologists classify the seahorse within the class Pisces, family Syngnathidae, and genus Hippocampus. Currently, seahorses enjoy a broad market both domestically and internationally, but a significant imbalance between supply and demand has led to a sharp decline in natural seahorse resources. Some areas once abundant with seahorses are now depleted of them. Consequently, the seahorse has been designated a key "Southern Medicinal Herb" for development by the Chinese government.

[0003] Seahorses have poor immunity and are extremely susceptible to disease when the external environment is harsh or changes greatly. At present, there are few reports on disease prevention and control in farmed seahorses at home and abroad. Common diseases in the farming process include bubble disease, swim bladder disease, gastrointestinal disease, skin disease, egg dinoflagellation, trichodiniasis, and blindness caused by insufficient light. Disease prevention and control should adhere to the principle of "prevention first, prevention and treatment combined".

[0004] Therefore, it is of great significance to establish a breeding method that can effectively prevent seahorse infection in intensive breeding. Summary of the Invention

[0005] In view of this, the main purpose of the present invention is to provide an intensive seahorse farming method, which reduces environmental pathogens, significantly improves the disease resistance, growth rate and farming efficiency of seahorses, and reduces overall costs through graded disinfection, feed feeding optimization, trace element supplementation and self-preparation technology of highly active bacterial agents.

[0006] To achieve the above object, the technical solution of the present invention is as follows:

[0007] An intensive seahorse breeding method comprises the following steps:

[0008] (1) Disinfection management:

[0009] Use hypochlorous acid to disinfect the aquaculture pond walls, bottom, oxygen pipes and feeding tools;

[0010] Carry out graded disinfection of water bodies:

[0011] a. After water inlet or water change, when there is a reservoir, the final concentration of hypochlorous acid is 15-25ppm (preferably 20ppm) to disinfect the reservoir, and when there is no reservoir, the hypochlorous acid is directly disinfected at 50-200ppm (preferably 150ppm) in the breeding pond;

[0012] b. After one week of water replacement, disinfect the water in the aquaculture pond with hypochlorous acid. Add hypochlorous acid at a final concentration of 150-250 ppm each time, with an interval of no more than 7 days.

[0013] c. Every 3 to 7 days, add Q life water (in the present invention, the pool is 30m) at a final concentration of 60 to 70ppm (preferably 67ppm) 3 , preferably add 2L of Q life water to increase the mineral content in the water quality and improve the survival rate of cultured seahorses);

[0014] Before entering the pond, the seahorse parents are placed in a container as a whole, soaked in hypochlorous acid with a concentration of 400-600ppm (preferably 500ppm) for 2-5 minutes, and then poured into the breeding pond;

[0015] Before the seahorse seedlings are placed in the pond, they are placed in a container and soaked in hypochlorous acid with a concentration of 150-250ppm (preferably 200ppm) for 2-5 minutes before being poured into the breeding pond;

[0016] (2) Bait treatment: Bait treatment: Live bait (artemia, copepods), frozen bait (mysid shrimp, artemia) or artificial compound feed can be fed. Before each feeding of frozen bait and live bait, thaw the frozen bait or concentrate the live bait and add 3-6ppm (preferably 5ppm) hypochlorous acid to disinfect the bait; this step can be skipped if artificial compound feed is used;

[0017] (3) Feeding:

[0018] The daily feeding rate is adjusted dynamically according to the growth stage of the seahorse: in the juvenile stage, the feeding rate is 8%-12%, and the hatching artemia is fed; in the middle stage, the feeding rate is 5%-8%, and the copepods are fed; in the adult stage, the feeding rate is 3%-5%, and the mysid shrimp is fed;

[0019] Among them, when the weight is less than 1.0g / tail, it is the foal stage; when the weight is 1.0-3.5g / tail, it is the middle horse stage; when the weight is greater than 3.5g / tail, it is the adult horse stage; seahorses are sampled weekly and the weight is adjusted dynamically according to the measurement results;

[0020] (4) Preparation and administration of microbial agents:

[0021] Using peptone, yeast extract powder and compound nutrient elements as raw materials, Bacillus-lactic acid bacteria agent is fermented and prepared;

[0022] Add Bacillus-Lactic Acid Bacteria compound agent at 8-12ppm after feeding the bait every day.

[0023] Furthermore, in step (1), the hippocampal transport parameters are:

[0024] Use a double-layer pure oxygen bag with a size of 30cm×30cm×75cm, and fill it with water to 1 / 4 of the bag capacity;

[0025] Each bag transports 3,000 seahorse fry or 60-80 seahorse parents, the water temperature is 16-20℃, and the transportation time is ≤20 hours;

[0026] The temperature difference between transportation water and aquaculture pond water is <3℃, and the salinity difference is <3‰.

[0027] Furthermore, step (3) also includes feeding and regulating according to the seahorse species, temperature and the amount of residual bait on the feeding table;

[0028] Among them, according to the seahorse species and temperature control, it specifically includes:

[0029] If the seahorse is a distended seahorse and the water temperature is <16°C or >19°C; if the seahorse is a lineated seahorse and the water temperature is <26°C or >29°C; or if the seahorse is a large seahorse and the water temperature is <24°C or >32°C; reduce the feeding rate by 20%-30%;

[0030] When the amount of residual bait on the feed table is >5%, the feeding rate will be reduced by 5%-10%; when all the bait is eaten, the feeding rate will be increased by 5%-10%.

[0031] Furthermore, step (3) also includes trace element supplementation, specifically: adding Q life water, a product of German AQUA ELECTRA company, to the culture pond at 10 ppm every 3-7 days.

[0032] Furthermore, in step (4), the mixing mass ratio of peptone, yeast extract powder and composite nutrient elements is 3-5:1-2:0.1-1;

[0033] The composite nutrient elements include ferric phosphate, magnesium sulfate, potassium sulfate and zinc sulfate, with a mass ratio of 90% ferric phosphate, 3.3% magnesium sulfate, 3.3% potassium sulfate and 3.3% zinc sulfate;

[0034] In the composite bacterial agent, the mixing mass ratio of Bacillus to lactic acid bacteria is 1:0.8-1.2, preferably 1:1.

[0035] Furthermore, the Q life water includes sodium, potassium, calcium, magnesium ions, sulfate, carbonate and bicarbonate, etc.

[0036] Furthermore, the hypochlorous acid comes from Shanghai Yishu Technology Co., Ltd., and Q life water comes from AQUAELECTRA, Germany.

[0037] Furthermore, the intensive seahorse breeding method of the present invention comprises the following steps:

[0038] 1. Disinfection management

[0039] Disinfection of tools and facilities: During the breeding preparation period, use hypochlorous acid from Shanghai Yishu Technology Co., Ltd. to spray the breeding pond walls, pond bottom, oxygen tubes and feeding tools according to the concentration in the instructions;

[0040] Disinfection of water bodies by stages: After water intake or water change, disinfect the water reservoir with a final concentration of 20ppm hypochlorous acid if there is a reservoir, and directly disinfect the breeding pond with 50-200ppm hypochlorous acid if there is no reservoir; one week after the water change, disinfect with hypochlorous acid (final concentration of 200ppm, interval no more than 7 days); before the seahorse parents are put into the pond, place them in a container as required, soak them in 500ppm hypochlorous acid for 2-5 minutes, and then pour them into the breeding pond;

[0041] Before placing seahorse seedlings into the pond, place them in a container as required, soak them in 200ppm hypochlorous acid for 2-5 minutes, and then pour them into the breeding pond;

[0042] Disinfection of seahorses: Before the seahorse parents are put into the pond, they should be placed in a container as required, soaked in 500ppm hypochlorous acid for 2-5 minutes, and then poured into the breeding pond; before the seahorse seedlings are put into the pond, they should be placed in a container as required, soaked in 200ppm hypochlorous acid for 2-5 minutes, and then poured into the breeding pond;

[0043] 2. Trace element supplementation

[0044] Qlife water from the German company AQUA ELECTRA is added to the aquaculture pond at a rate of 10ppm every 3-7 days. Qlife water contains sodium, potassium, calcium, magnesium ions, sulfates, carbonates, and bicarbonates.

[0045] 3. Feeding

[0046] Dynamic feeding rate: The daily feeding rate is adjusted dynamically according to the growth stage of the seahorse: in the juvenile stage (<1.0g / tail), feed with hatched Artemia, with a feeding rate of 8%-12%; in the middle stage (1.0-3.5g / tail), feed with copepods, with a feeding rate of 5%-8%; in the adult stage (>3.5g / tail), feed with mysid shrimp, with a feeding rate of 3%-5%;

[0047] Feeding control:

[0048] For seahorses with puffy belly: when the water temperature is <16°C or >19°C; for seahorses with lined hair: when the water temperature is <26°C or >29°C; for large seahorses: when the water temperature is <24°C or >32°C, reduce the feeding rate by 20%-30%. Adjustments will be made based on the amount of residual bait on the feed table (reduce the amount by 5%-10% when the residual bait is >5%, and increase the amount by 5%-10% when the bait is completely eaten) and weekly sampling weight measurements.

[0049] 4. Preparation and administration of microbial agents

[0050] Self-preparation of microbial agents: using peptone, yeast extract powder and compound nutrient elements (mass ratio 3-5:1-2:0.1-1) as raw materials, fermentation produces Bacillus and lactic acid bacteria microbial agents;

[0051] Bacterial agent administration: After feeding twice a day, 10 ppm of Bacillus-Lactic acid bacteria compound preparation was administered, wherein the mixed mass ratio of Bacillus:Lactic acid bacteria was 1:1.

[0052] That is, the invention relates to an intensive seahorse breeding method with high efficiency and profit, focusing on solving the problems of incomplete disinfection, diseased bait and insufficient activity of microbial agents in traditional breeding. The technical solution includes: Disinfection management: using hypochlorous acid from Shanghai Yishu Technology Co., Ltd. for disinfection, and conducting graded disinfection of breeding ponds, tools, water bodies, seahorse stallions and seedlings. The seahorse parents are instantly disinfected with hypochlorous acid before entering the pond (500ppm, 2 minutes), and the water tank and water change are precisely controlled at a concentration of 20-200ppm to reduce the risk of pathogens. Bait optimization: dynamically adjust the feeding rate according to the growth stage of the seahorse, and disinfect the bait before feeding. And add Bacillus-Lactic acid bacteria composite preparations in batches to achieve synergistic effects on intestinal health, immune enhancement and parasite prevention and control. At the same time, the microbial agent is self-prepared: highly active Bacillus and lactic acid bacteria are produced by fermentation of peptone, yeast extract powder and composite nutrients. The cost is only 10% of the commercial preparation, and there is no contamination by miscellaneous bacteria. The present invention significantly improves the survival rate (survival rate ≥ 90%), growth efficiency and disease resistance of seahorses through multi-link coordinated control, while reducing breeding costs, and is suitable for large-scale seahorse breeding.

[0053] The beneficial effects of the present invention include at least:

[0054] (1) The disinfection scheme of the present invention is efficient and safe: the hypochlorous acid disinfection system reduces pathogen resistance, instant disinfection of seahorses reduces the risk of infection when entering the pool, and regular disinfection prevents seahorse disease;

[0055] (2) Trace element regulation: After adding trace elements daily, the shrimp's immunity and energy are improved, and the molting is strong and rapid;

[0056] (3) The solution of the present invention can improve growth efficiency: dynamic feeding rate combined with microbial agent and live knot liquid feeding in batches can increase feed utilization rate by 15%-22%;

[0057] (4) The solution of the present invention significantly reduces breeding costs: the activity of the self-fermentation bacterial agent is 2-3 times that of the commercial preparation, and the cost is less than 1 / 10 of it;

[0058] (5) The scheme of the present invention has outstanding comprehensive benefits: the survival rate of seahorse parents and seedlings during transportation can be ≥90%, the breeding cycle is shortened by 10%-15%, and the disease incidence rate is reduced by more than 50%. DETAILED DESCRIPTION

[0059] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0060] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0061] The solution proposed by the present invention is described in detail below through specific embodiments:

[0062] Example 1

[0063] 1. Disinfection management

[0064] Disinfection of tools and facilities: After the aquaculture pond is cleaned, use 50-200ppm concentration of hypochlorous acid to spray the aquaculture pond wall, pond bottom, oxygen tube and feeding tools. Hypochlorous acid is purchased from Shanghai Yishu Technology Co., Ltd. (product effective chlorine concentration 500ppm).

[0065] Three hours before the water enters the reservoir, disinfect the reservoir with 20ppm hypochlorous acid.

[0066] After one week of water change, hypochlorous acid was used to disinfect the water body at a final concentration of 200ppm, with an interval of no more than 7 days (purchased from Shanghai Yishu Technology Co., Ltd.); Qlife water was added every 3 to 7 days at a final concentration of 67ppm. 3 , add 2L of Q life water (purchased from AQUA ELECTRA, Germany) to increase the mineral content in the water and improve the survival rate of cultured seahorses.

[0067] 2. Seahorse transportation and disinfection

[0068] Transport of seahorses: Use double-layer pure oxygen-filled bags (30cm×30cm×75cm), with the water volume being 1 / 4 of the bag capacity; each bag transports 3,000 seahorse fry or 60-80 seahorse parents, the water temperature is 16-20℃, and the transport time is ≤20 hours; the temperature difference between the transport water and the breeding pond water is <3℃, and the salinity difference is <3‰.

[0069] Disinfection of seahorses: Before the seahorse parents are put into the pond, they should be placed in a container as required, soaked in 500ppm hypochlorous acid for 2-5 minutes, and then poured into the breeding pond; before the seahorse seedlings are put into the pond, they should be placed in a container as required, soaked in 200ppm hypochlorous acid for 2-5 minutes, and then poured into the breeding pond;

[0070] 3. Bait processing

[0071] Feeding can consist of live bait (artemia and copepods), frozen bait (mysid shrimp, artemia), or artificial compound feed. Before each feeding of frozen and live bait, thaw the frozen bait or concentrate the live bait and disinfect it with 3-6 ppm hypochlorous acid. This step can be skipped if using artificial compound feed.

[0072] 4. Feeding

[0073] Dynamic feeding rate: The daily feeding rate is adjusted dynamically according to the growth stage of the seahorse: in the juvenile stage (<1.0g / tail), feed with hatched Artemia, based on 8%-12% of the total weight of the seahorse; in the middle stage (1.0-3.5g / tail), feed with copepods, based on 5%-8% of the total weight of the seahorse; in the adult stage (>3.5g / tail), feed with mysid shrimp, based on 3%-5% of the total weight of the seahorse;

[0074] Feeding control:

[0075] Seahorse with puffed belly: When the water temperature is <16℃ or >19℃, adjust the amount dynamically based on the amount of residual bait on the feed table (reduce the amount by 5%-10% when the residual bait is >5%, and increase the amount by 5%-10% when the bait is completely eaten) and the weekly sampling weight measurement results;

[0076] Trace element supplementation

[0077] Q life water (purchased from AQUA ELECTRA, Germany) is added to the aquaculture ponds at a concentration of 10 ppm every 3-7 days to maintain the ecological balance of the water. Q life water contains sodium, potassium, calcium, magnesium ions, sulfates, carbonates, and bicarbonates.

[0078] 5. Preparation and feeding of microbial agents

[0079] Inoculum preparation: Using peptone, yeast extract, and a complex nutrient element (mass ratio of 4:1.5:0.1) as raw materials, ferment for 8 hours to produce Bacillus and lactic acid bacteria inoculum. The complex nutrient element composition includes 90% by weight of ferric phosphate, 3.3% by weight of magnesium sulfate, 3.3% by weight of potassium sulfate, and 3.3% by weight of zinc sulfate.

[0080] Bacterial agent feeding: After feeding the bait twice a day, add 10ppm Bacillus-Lactic acid bacteria compound preparation, and the mass ratio of Bacillus:Lactic acid bacteria in the compound preparation is 1:1.

[0081] In this embodiment, the feed coefficient of the Artemia stage is 6.5, and the feed coefficient of the frozen copepod and mysid stage is 4.3. After 290 days of culture, the average weight of the seahorses reaches more than 3g, and the survival rate is 90%.

[0082] Comparative Example 1

[0083] Traditional breeding methods

[0084] Traditional breeding methods used disinfection equipment to sterilize the aquaculture water, but did not use probiotics or Qlifewater. After 290 days of culture using this method, the average weight of seahorses raised using this method was 2.6g, with a survival rate of 76%. Example 1 showed a 15% increase in weight compared to seahorses raised using traditional breeding methods over the same period. This faster growth rate also shortened the breeding period, and the survival rate increased by 18%.

[0085] Comparative Example 2

[0086] This example differs from Example 1 in that, during disinfection, hypochlorous acid was replaced with sodium hypochlorite, and bacterial preparations were used to regulate the seahorse intestinal tract and the water environment. Because sodium hypochlorite is highly irritating to cultured organisms, it cannot be used in aquaculture ponds containing cultured organisms. Due to the lack of regular disinfection of the aquaculture water, the incidence rate increased significantly, and by the end of the aquaculture cycle, less than one-third of the seedlings from the batch remained.

[0087] After 290 days of culture, the average weight of the seahorses in this example was 2.1 g, and the survival rate was 30%. Compared with Example 1, the weight at the end of culture was 30% lighter, and the survival rate was 60% lower.

[0088] Comparative Example 3

[0089] The difference between this embodiment and embodiment 1 is that no bacterial preparations and Q life water were used during the breeding period. Bacillus can reduce ammonia nitrogen, nitrite, and hydrogen sulfide in the breeding water, improve the bottom water environment of the breeding water, and produce protease, lipase, and amylase to promote the digestion and absorption of nutrients and feed by the seahorse, thereby increasing the utilization rate of feed. Lactic acid bacteria can colonize the seahorse's intestines and compete with harmful bacteria for the ecological environment, secrete vitamins, lactic acid, and other amino acids, and promote digestion and absorption. Both bacteria can enhance the immunity of the seahorse, and their combined use can regulate water quality, promote digestion and absorption, enhance disease resistance, and reduce stress.

[0090] After 290 days of culture, the average weight of seahorses in this example was 2.9g, with a survival rate of 86%. The feed conversion ratio during the Artemia stage was 8.1, while the feed conversion ratio during the frozen copepod and mysid stage was 5.5. Compared to Example 1, the final weight was slightly less by 3%, and the feed conversion ratios during the two stages were 1.25 and 1.28 times higher, respectively. This demonstrates that Example 1 achieved higher feed utilization, increasing feed conversion ratios by 20% and 22%, respectively, compared to this culture method.

[0091] Comparative Example 4

[0092] This embodiment differs from Example 1 in that traditional disinfection equipment is used to disinfect the aquaculture water, rather than regularly adding Q life water to the aquaculture pond. Traditional aquaculture equipment disinfects incoming water and then allows it to rest. This lacks the flexibility of hypochlorous acid disinfection and is incapable of disinfecting the aquaculture pond water during the aquaculture period. It is impossible to accurately disinfect the aquacultured seahorses, and the disinfection effect is unstable due to factors such as aging equipment. Without Q life water feeding during the aquaculture period, the seahorses cannot be replenished with the minerals and elements necessary for growth, which affects their growth rate.

[0093] After 290 days of culture, the average weight of the seahorses in this example was 2.0 g, and the survival rate was 20%. Compared with Example 1, the weight at the end of culture was 33% lighter, and the survival rate was 80% lower.
