RYNAN Smart LED

The RYNAN® Smart LED system provides controlled photobiological stimulation in shrimp ponds during night hours.

Using optimized blue and green light spectrums, the system influences shrimp behavior by increasing nighttime feeding activity and supporting natural molting processes. This extends active feeding time beyond daylight hours and improves metabolic performance in intensive shrimp farming systems.

Shrimp naturally reduce feeding activity at night and may switch to individual foraging or cannibalistic behavior.

The RYNAN LED lighting system helps:

• Increase nighttime feeding activity

• Improve feed utilization efficiency

• Support better Feed Conversion Ratio (FCR)

• Accelerate growth rate

Under optimized farm conditions, growth rate improvements of up to 15–20% may shorten cultivation cycles, potentially increasing annual production cycles.

Results depend on biomass density, feeding strategy, and overall pond management.

The LED system typically operates for 4–6 hours during late-night periods (e.g., 1:00 AM to 6:00 AM), when dissolved oxygen and feeding patterns are critical.

The schedule can be programmed through the TOMGOXY® App, allowing gradual light intensity adjustments to simulate natural sunrise patterns.

Blue and green wavelengths trigger different physiological responses in shrimp:

• Blue light stimulates activity and feeding behavior

• Green light supports molting cycles and sustained movement

The combined spectrum optimizes nighttime feeding efficiency while maintaining environmental balance.
