Analysis of Propagation Characteristics of LED Light Source in Aquaculture Water

Light is an important environmental factor affecting the growth and development of aquatic animals,and its propagation characteristics in aquaculture waters are still unclear.In this experiment,five light emitting diode(LED)light sources were selected:red(peak at 645 nm),green(510 nm),blue(445 nm),U...

Summary:Light is an important environmental factor affecting the growth and development of aquatic animals,and its propagation characteristics in aquaculture waters are still unclear.In this experiment,five light emitting diode(LED)light sources were selected:red(peak at 645 nm),green(510 nm),blue(445 nm),UVA(355 nm),and full spectrum(the wavelength of white light emitted by blue light excited silicate phosphor can reach~l400~800 nm).The radiation irradiance was adjusted to 60 W/m2,and the propagation law of irradiance was studied under different breeding water quality environments to provide references in order to meet the photobiological requirements of indoor factory aquaculture and the standardization control of aquaculture environment.The experimental results showed that the transmittance of five different LED light sources decreases with the increase in water depth.The variation trends of different light sources were different.When the water depth was 10 cm,the green light showed the largest transmittance(46.01
