Description

Technical Field

[0001] The invention relates to the field of aquatic product breeding methods, and in particular to a breeding method for young sea cucumbers. Background Art

[0002] Sea cucumber (Apostichopus japonicus) belongs to the phylum Echinodermata, class Holothuria. Due to its high nutritional and medicinal value, it is highly favored in my country's aquaculture industry. However, in recent years, the market demand for sea cucumbers has continued to increase, resulting in overfishing of wild sea cucumbers. Since sea cucumbers are relatively fragile in the early growth stage and are easily affected by the surrounding environment, their wild resources are facing greater pressure. At present, many studies are committed to improving the breeding efficiency of sea cucumbers and thus increasing production, such as improving feed formulas, improving the breeding environment, and reducing environmental impacts during the breeding process. In the current breeding of juvenile sea cucumbers, light environment regulation lacks considerable attention and technical support, so establishing an effective light environment regulation technology is of great significance to promoting the growth of juvenile sea cucumbers.

[0003] On the other hand, light, as an important and complex ecological and environmental factor, has a significant impact on the growth, survival, reproduction, behavior and biological rhythm of aquatic organisms. However, in the underwater environment, the spectral composition changes. As the depth of the water layer increases, the light decays rapidly, and high-energy short-wavelength blue light dominates in deep water, while low-energy long-wavelength red light can only penetrate shallow water. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a method for cultivating young ginseng, which can effectively improve the growth rate.

[0005] In order to solve the technical problem of the present invention, the present invention provides a method for cultivating young ginseng, which comprises:

[0009] The light of the preset wavelength band is emitted by a light source device, and the peak wavelength of the light source device is 595-600 nm and / or 630-635 nm.

[0014] As an improvement of the above technical solution, in the step of putting the young sea cucumber into the aquaculture water body and starting aeration at the same time, the young sea cucumber is a young sea cucumber that is fertilized for 40 to 50 days, and the aeration volume is 20 to 50 L·m -3 ·h -1 .

[0015] As an improvement of the above technical solution, in the step of feeding the feed according to a preset cycle and irradiating the young sea cucumber with light of a preset wavelength, the feeding cycle adopted is 1 to 2 times / day, and the daily feeding amount is 2 to 5wt% of the body weight of the young sea cucumber;

[0016] The feed comprises the following components by weight: 40-60 parts of sea mud, 30-40 parts of large leaf vegetables, 10-20 parts of compound materials, 3-10 parts of Sargassum, and 3-10 parts of EM bacteria;

[0017] Wherein, the batch material comprises the following components in weight percentage:

[0018] Fish meal 20-45%, soybean meal 20-60%, spirulina 5-10%, corn flour 10-45%.

[0019] As an improvement of the above technical solution, the aquaculture water body includes a first aquaculture water body, a second aquaculture water body and a third aquaculture water body distributed in sequence from the bottom to the top of the aquaculture pond, and the first aquaculture water body, the second aquaculture water body and the third aquaculture water body have the same depth;

In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use scenarios of other materials.

[0033] The present invention provides a method for cultivating young ginseng, which specifically comprises:

[0034] (1) constructing a breeding pond containing breeding water;

[0035] (2) putting the young ginseng into the aquaculture water and starting aeration;

[0036] (3) feeding the fry according to a preset cycle and irradiating the fry with light of a preset wavelength;

[0037] The light of the preset wavelength is emitted by the light source device, and the peak wavelength of the light source device is 595-600nm and / or 630-635nm. Based on the irradiation of the light of the preset wavelength, a suitable light intensity can be formed in various parts of the aquaculture water body, thereby promoting the movement activity of the young sea cucumber, improving its growth and metabolism, and thus improving the growth rate of the young sea cucumber.

[0038] Specifically, in one embodiment, the aquaculture water body includes a first aquaculture water body, a second aquaculture water body and a third aquaculture water body distributed in sequence from the bottom to the top of the aquaculture pond, and the depths of the first aquaculture water body, the second aquaculture water body and the third aquaculture water body are the same.

[0039] The light intensity in the first aquaculture water body, the second aquaculture water body, and the third aquaculture water body conforms to the following relationship:

[0040]

[0041] Among them, I b is the average light intensity in the first aquaculture water body, I mis the average light intensity in the second aquaculture water body, I t is the average light intensity in the third aquaculture water body.

[0042] It should be noted that the attenuation degree of light of different wavelengths in natural seawater / artificial seawater is inconsistent. At the same time, the water condition and aeration amount during the breeding process will affect the distribution of light intensity. The inventors found that light of different light intensities has a greater impact on the growth rate of young sea cucumbers. After a large number of experiments, it was concluded that when the light intensity at different depths in the breeding water body is coordinated and controlled, the movement activity of young sea cucumbers can be effectively improved, and their growth and metabolism can be improved, thereby increasing the growth rate of young sea cucumbers.

[0043] Specifically, in step (1), the culture pond can be a PVC plastic culture barrel or a cement culture pond equipped with a net cage, but is not limited thereto. The culture pond contains a culture water body, which can be seawater or artificial seawater, but is not limited thereto.

[0044] Specifically, the temperature of the aquaculture water is 21-23°C, exemplarily 21.5°C, 22°C, 22.5°C or 22.8°C, but not limited thereto.

[0045] Specifically, in one embodiment, the depth of the aquaculture water body is 70-90% of the depth of the aquaculture pond, exemplarily 72%, 76%, 80%, 84% or 88%, but not limited thereto. More specifically, the depth of the aquaculture water body is 60-70 cm, exemplarily 62 cm, 64 cm, 66 cm or 68 cm, but not limited thereto.

[0046] Specifically, in one embodiment, the light source device is arranged at 90 to 100 cm above the aquaculture water body. By controlling the distance of the light source device, the distribution of light can be optimized, the uniformity of light can be improved, and the growth rate of young sea cucumbers can be improved.

[0047] Specifically, in step (2), the young sea cucumber is a young sea cucumber fertilized 40 to 90 days ago, preferably a young sea cucumber fertilized 40 to 50 days ago. The amount of young sea cucumbers input is 14 to 20 young sea cucumbers / 100L of aquaculture water.

[0048] Specifically, in step (2), the aeration volume is 10 to 80 L·m -3 ·h -1 When the aeration rate is too low, the juvenile ginseng has low activity and low growth rate. When the aeration rate is too high, it will affect the distribution of light intensity. For example, the aeration rate is 15L·m -3 ·h -1 、30L·m -3 ·h -1 、45L·m -3 ·h -1 、60L·m -3 ·h-1 or 75L·m -3 ·h -1 , but not limited to this. Preferably 20 to 50 L·m -3 ·h -1 .

[0049] Specifically, in step (3), the photoperiod used is: 10-16 hours of light / day, 8-14 hours of darkness / day. Exemplarily, it is 11 hours of light / day + 13 hours of darkness / day, 13 hours of light / day + 11 hours of darkness / day, or 15 hours of light / day + 9 hours of darkness / day, but not limited thereto. Preferably, the photoperiod is 14 hours of light / day, 10 hours of darkness / day.

[0050] Specifically, in step (3), the light intensity used is 5 to 20 μmol·m -2 ·s -1 , exemplarily 7 μmol·m -2 ·s -1 , 9 μmol·m -2 ·s -1 , 11 μmol·m -2 ·s -1 , 13 μmol·m -2 ·s -1 , 15 μmol·m -2 ·s -1 or 18 μmol·m -2 ·s -1 , but not limited thereto. Preferably, the light intensity is 9 μmol·m -2 ·s -1 It should be noted that the light intensity here refers to the average light intensity, that is, the average light intensity obtained by averaging the light intensity measured at different locations at different depths in the culture pond.

[0051] Specifically, in step (3), the feeding cycle is 1 to 2 times / day, preferably 1 time / day. The feeding amount of the feed is 2 to 5 wt% of the weight of the young sea cucumber, exemplarily 2.4 wt%, 2.8 wt%, 3.2 wt%, 3.6 wt%, 4 wt%, 4.4 wt% or 4.8 wt%, but not limited thereto.

[0052] Specifically, in step (3), the feed commonly used in the art can be used for feeding, but it is not limited thereto. Preferably, in one embodiment, the feed comprises the following components by weight: 40-60 parts of sea mud, 30-40 parts of large leaf vegetables, 10-20 parts of compound materials, 3-10 parts of Sargassum, and 3-10 parts of EM bacteria; wherein the compound materials comprise the following components by weight percentage: 20-45% of fish meal, 20-60% of soybean meal, 5-10% of spirulina, and 10-45% of corn flour.

[0053] In addition, during the breeding process, water is changed regularly to prevent water pollution from affecting the distribution of light intensity. Specifically, the water change cycle is 7 to 10 days, and the amount of water changed is 75 to 90% of the breeding water.

[0054] Specifically, in some embodiments of the present invention, in one example, young sea cucumbers with substantially the same body weight and average body length specifications (difference is less than or equal to 5%) are selected for breeding.

[0055] Preferably, in another embodiment, young sea cucumbers with certain differences in weight and average length can be selected for breeding together, specifically, the weight difference is ≤50%, and the more preferred weight difference is 20-40%. When breeding young sea cucumbers with certain differences, the light source device includes at least one orange LED and at least one red LED, the peak wavelength of the orange LED is 595-600nm, and the peak wavelength of the red LED is 630-635nm; the power ratio of the orange LED to the red LED is (3-5):1, so that the light intensity in the first breeding water body, the second breeding water body, and the third breeding water body meets the following relationship:

[0056]

[0057] Among them, I b is the average light intensity in the first aquaculture water body, I m is the average light intensity in the second aquaculture water body, I t is the average light intensity in the third aquaculture water body.

[0058] Based on the above-mentioned lighting scheme, young ginseng of different specifications can have a higher growth rate. It should be noted that, firstly, in the conventional breeding process, it often takes a lot of time to distinguish the cultured ginseng seedlings, and then breed them in grades. Secondly, the inventor unexpectedly discovered during the research process that the movement behaviors of different specifications under the irradiation of light with different light intensities and different peak wavelengths have great differences. For example, young ginseng of smaller specifications move more strongly under red light, while young ginseng of larger specifications move more strongly under orange light. Thirdly, in the upper and middle layers of the breeding water body where feed is relatively abundant, young ginseng of smaller specifications are often distributed more, while young ginseng of larger specifications are often in the middle and bottom layers. Based on the above research, the present application adopts a technical solution of lighting with a combination of orange LED and red LED, so that water layers of different depths have suitable light intensity, so that young ginseng of different specifications maintain a good state of movement and improve their growth rate.

[0059] The present invention is described below with specific embodiments:

[0060] The following examples and comparative examples were all conducted at the Aquaculture Facility and Equipment Engineering Technology Research Center of Dalian Ocean University. The breeding pond used was a PVC plastic barrel, which was cylindrical, 80 cm in diameter, 80 cm in height, 60-70 cm in depth, and the water temperature for young ginseng cultivation was 21-23°C. A light source device was suspended 100 cm above the aquaculture water body. Aeration was performed continuously during the breeding process, with an aeration volume of 45 L·m -3 ·h -1 Feed once a day, the feed formula is as follows: 45 parts of sea mud, 35 parts of large leaf vegetables, 10 parts of compound feed (32% fish meal, 30% soybean meal, 8% spirulina, 30% corn flour), 5 parts of Sargassum, 5 parts of EM bacteria.
