In an artificial environment you could control the flow of a saltwater stream that only dies down during the optimal times for their equivalent of the parasympathetic nervous system. You could probably control short term and long term fluctuations and experiment to see when they need breaks to feel hunger and breed. Breeding season is often associated with an influx of new, clean, alkaline water (rainfall or glacial melt), warmer temperatures, and sexually maturing younger specimens.
