This invention discloses a method for regulating the light environment to promote gonadal development in female Russian sturgeon, belonging to the field of aquaculture technology. By regulating light intensity and photoperiod during stages II and III of ovarian development in female Russian sturgeon, the gonadal development rate is accelerated; the daytime light intensity is 7.99±4.44 W / m². 2 / s, nighttime light intensity 4.42±0.95W / m 2 The light cycle is 18-24 hours of light followed by 0-6 hours of darkness, with artificial lighting for 4-6.3 hours, and a 24-hour cycle. By adjusting the intensity of natural daytime light and supplemental LED lighting at night, the light intensity and photocycle are modified to meet the light environment requirements of flow-through cultured female Russian sturgeon during gonadal development. This promotes the speed of gonadal development, increases the average egg diameter, reduces individual differences in gonadal development among female Russian sturgeon, and ultimately improves the productivity and economic benefits of aquaculture enterprises.

This invention relates to the field of lighting design technology, and in particular to a method, apparatus, equipment, and storage medium for energy-saving design of three-dimensional lighting. It constructs a digital twin model using spatial structure data and surface optical attribute data of a target scene. Target and constraint templates are matched according to scene type to meet complex lighting needs across multiple scenes, improving applicability. A multi-objective optimization model is constructed based on the digital twin model and target and constraint templates to optimize energy-saving solutions, minimizing energy consumption while ensuring light intensity, light quality, and light cycle. Customized optoelectronic device processing instructions are generated based on the optimal energy-saving solution, shortening the customization cycle. The actual illumination data of the target scene is compared with the simulation predictions of the digital twin model. The digital twin model is calibrated based on the comparison discrepancies. The three-dimensional lighting system undergoes full lifecycle operation and maintenance, achieving closed-loop management of the entire process from perception, design optimization, deployment, calibration to operation and maintenance, thus improving the level of intelligence.

The invention provides an anti-stress breeding method for Pseudosciaena crocea fries of the sal family, and belongs to the technical field of aquaculture. A bright light period in a light period is divided into three stages: in the first stage, the light intensity is set to be 200-300 lux, the color temperature is set to be 4800-5200 K, the water flow speed is set to be 0.09-0.12 m / s, and sound wave stimulation 1 is matched; in the second stage, the light intensity is reduced to 130-160 lux, the color temperature is reduced to 3800-4200 K, and the water flow speed is slowed down to 0.06-0.08 m / s; in the third stage, the light intensity is reduced to 80-110 lux, the color temperature is reduced to 3300-3600 K, the water flow speed is reduced to 0.05 m / s, and sound wave stimulation 2 is matched; in the dark light period, illumination, water flow and sound wave stimulation are closed, and a dark environment without light and sound is created. The method can effectively reduce the fry death rate in the initial breeding stage, improve the breeding success rate and promote healthy growth of the fry.
