Lighting system and control for experimenting in aquaculture
A method of experimenting on aquatic life in an indoor facility and a lighting assembly for accomplishing the same. The lighting assembly includes a lighting device that emits light at a predetermined wavelength that provides a minimum water penetration depth and is positioned in a manner to provide uniform lighting at the air and water interface within a containment unit housing the aquatic life. The on and off functions are also controlled by the lighting assembly to provide a gradual turn on and turn off to prevent interference of effects of lighting with experimental results.
1. A method of experimenting on aquatic life in an indoor facility, comprising:
providing a containment unit for housing aquatic life;
providing a lighting system including a lighting assembly having a plurality of spaced directional light emitting diodes;
placing the lighting assembly above the containment unit to provide even lighting at an air and water interface within the containment unit and gradually increasing intensity of the light emitting diodes with a programmable dimming device over a predetermined period of time to reduce the effect of the light emitting diodes on the aquatic life.
2. The method of claim 1 wherein the predetermined period of time is two hours.
3. The method of claim 1 further comprising:
gradually decreasing intensity of the light emitting diodes over a second predetermined period of time.
4. The method of claim 3 wherein the second predetermined period of time is two hours.
5. The method of claim 1 wherein the plurality of spaced directional light emitting diodes emit light at a predetermined wavelength to reduce the penetration of light into the water in the containment unit.
6. The method of claim 5 wherein the predetermined wavelength is in a range between 630 NM and 750 NM .
