Integrated fish diversion system, and lighting device used therein
Described are various embodiments of an integrated fish diversion system, and lighting device used therein. One embodiment provides a system for diverting approaching fish from a predominant water flow path and toward a bypass. The system comprises a structural diversion assembly to be disposed across the predominant water flow path to guide the approaching fish along the structural diversion assembly to the bypass, while allowing passage of water through the structural diversion assembly along the predominant water flow path. The system further comprises one or more lighting devices to be cooperatively disposed in relation to the structural diversion assembly to further guide the approaching fish toward the bypass; and a controller operatively coupleable to the one or more lighting devices and operable to select an output spectrum thereof to optimize fish guidance thereby.
1. A lighting system for triggering different behavioral responses in fish, the system comprising:
one or more lighting devices each comprising one or more lighting elements and associated drivers operable to output light having a variable visible output spectrum and a variable output intensity in response to operational parameters communicated thereto;
said operation parameters being provided so as to selectively influence said behavioral responses of one more species of fish within a given environment;
each one of said lighting devices comprising a water submersible housing for housing said one or more lighting elements and associated drivers and for providing a water submersible communication interface; and
a control interface operatively coupleable to said water submersible communication interface and operable to receive as input, and communicate said operational parameters to said lighting devices.
2. The lighting system of claim 1 , wherein said lighting elements comprise LEDs.
3. The lighting system of claim 1 , further comprising a computer-implementable graphical user interface (GUI) for setting said operational parameters and communicating same via said control interface, wherein said GUI comprises a scheduling interface for scheduling designated changes to said operational parameters over time.
4. The lighting system of claim 1 , said control interface further operatively coupleable to one or more environmental sensors integrated or associated with each of said lighting devices to receive one or more of water temperature and water turbidity readings therefrom, and further operable to automatically adjust said operational parameters as a function of said readings.
5. The lighting system of claim 1 , wherein said one or more lighting devices comprise two or more lighting devices, and wherein said control interface is operable to select, for at least two of said two or more lighting devices, at least one of distinct output spectra and distinct output intensities.
6. The lighting system of claim 1 , further comprising a water monitor for monitoring one or more of water temperature and turbidity, said control interface further operable to adjust an intensity of said one or more lighting devices as a function of one or more of said water temperature and turbidity.
7. The lighting system of claim 1 , wherein said control interface is further programmable to automatically select at least one of different output spectra and output intensities over time as a function of a designated schedule.
8. The lighting system of claim 7 , wherein said designated schedule is designated as a function of one or more of a time of day, a season and known species-dependent responses for species anticipated to approach the system in different time periods.
9. The lighting system of claim 1 , wherein said behavioural response is a phototactic response.
