Description

Technical Field

[0001] The invention relates to the field of animal breeding equipment, and in particular to a light source device for breeding young sea cucumbers. Background Art

[0002] Light is one of the important environmental factors that regulate the growth, development, energy metabolism and reproduction of aquatic animals. It includes three elements: light intensity, spectrum and photoperiod. Its changes directly or indirectly affect the feeding, growth, development, survival and reproduction of aquatic animals. During the breeding process, different species and stages of sea cucumbers require different light conditions for growth and development.

[0003] The physiological and behavioral characteristics of most marine organisms are the result of long-term adaptation to the environment in which they live. Sea cucumbers live in a dark environment in nature, and studies have shown that the growth performance of sea cucumbers is improved under light conditions. Different spectra and light intensities have different effects on the growth and development of sea cucumbers at different growth stages.

[0004] Sea cucumber (Apostichopus japonicus) belongs to the phylum Echinodermata, class Holothuria. 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 devoted 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 young 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 young sea cucumbers.

[0035] See also Figure 1 One embodiment of the present invention provides a light source device for juvenile sea cucumber farming, which includes: a light source module 11 and a modulation module 12. The light source module 11 includes at least one orange light LED and / or at least one red light LED. The peak wavelength of the orange light LED is 595 to 600 nm, exemplarily 596 nm, 597 nm, 598 nm or 599 nm, but not limited thereto. The peak wavelength of the red light LED is 630 to 635 nm, exemplarily 631 nm, 632 nm, 633 nm or 634 nm, but not limited thereto. When irradiated with light based on the above-mentioned preset wavelength band, a suitable light intensity can be formed in various parts of the farming water body, thereby promoting the movement activity of the juvenile sea cucumber, improving its growth and metabolism, and thereby improving the growth rate of the juvenile sea cucumber.

[0036] The modulation module 12 is connected to the light source module 11, and is used to adjust the driving electric energy value of the light source module 11 so that the aquaculture water in the aquaculture pond receives light of a preset light intensity. Specifically, the driving electric energy value may be current or voltage, but is not limited thereto; preferably, it is current. Specifically, in one embodiment of the present invention, the modulation module 12 may adjust each LED individually. In another embodiment of the present invention, the modulation module 12 may adjust the light source module 11 as a whole, but is not limited thereto.

[0037] Preferably, in one embodiment, after being adjusted by the modulation module 12, the preset light intensity 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 preset light intensity is 9 μmol·m -2 ·s -1 It should be noted that the preset light intensity here refers to the average light intensity, that is, the average light intensity obtained after measuring at different positions at different depths in the breeding pond.

[0038] More preferably, 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 sequentially 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;

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

[0040]

[0041] 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.

[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. For this reason, the present invention is based on a large number of experiments and concluded that when the light intensity at different depths in the breeding water 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] Preferably, see Figure 2In one embodiment of the present invention, the light source equipment for juvenile sea cucumber farming also includes a timing module 13, which is connected to the light source module 11, and can turn on or off the light source module 11 according to a preset light cycle. Specifically, the preset light cycle is: 10 to 16 hours of light / day, 8 to 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 to this. Preferably, the preset light cycle is 14 hours of light / day, 10 hours of darkness / day.

[0044] Preferably, in one embodiment of the present invention, the light source module 11 includes at least one orange LED and at least one red LED, and the light emitted by the orange LED and the red LED is mixed to form light of other colors, further improving the growth rate of young ginseng. Figure 3 , based on this embodiment, the light source device further includes a light quality module 14, which is used to control the driving power values ​​of the orange light LED and the red light LED respectively to obtain light of a preset wavelength band. Specifically, the light quality module 14 is connected to the light source module 11, and can control the driving power values ​​of the orange light LED and the red light LED respectively to obtain a preset illumination spectrum. Specifically, the driving power value can be current or voltage, but is not limited thereto; preferably, it is current. Specifically, by controlling the driving power value, some of the multiple LEDs can be turned off and others can be turned on; or multiple LEDs can be turned on, but the driving power values ​​are different, so that different colors of light can be mixed in a preset proportion to obtain light of a preset wavelength band required for illumination. Preferably, in one embodiment of the present invention, the light quality module 14 adjusts the power ratio of the orange light LED and the red light LED to (3 to 5): 1. Exemplarily, it is 3.3:1, 3.6:1, 3.9:1, 4.2:1, 4.5:1 or 4.8:1, but is not limited thereto.

[0045] More preferably, based on this embodiment, the light intensity in the first aquaculture water body, the second aquaculture water body, and the third aquaculture water body meets the following relationship:

[0046]

[0047] 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.

[0048] 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, this embodiment 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.

[0049] The present invention is described below with specific embodiments:
