Feed Less, Grow More: What Better Fish Lighting Can Do

Written by Kiril Stoimenov | Oct 15, 2025 11:26:25 AM

You’re constantly trying to optimise feed usage, reduce waste, and keep your fish growing consistently.

What if we told you that
lighting could help with all three? 

Let’s break down how. 

The Problem: Feed Waste and Uneven Growth 

Feeding is one of the most expensive aspects of fish farming. But poor lighting can lead to: 

  • Missed pellets due to low visibility 
  • Fish crowding in dark areas 
  • Uneven access to food, leading to size variation 
  • Higher aggression and stress during feeding 


That’s wasted money and wasted potential. 

The Cause: Inconsistent Lighting Conditions 

Without a controlled lighting plan, your fish experience unnatural day-night patterns, random shadows, and abrupt light changes. This leads to unpredictable behaviour, stress responses, and inefficient feeding. 

The Solution: Lighting That Guides Natural Behaviour 

HATO Aqua systems help restore a natural rhythm. Here's how: 

  • Uniform light distribution encourages fish to stay evenly spread 
  • Gradual light transitions simulate sunrise and sunset 
  • Spectrum-tuned LEDs help fish see feed clearly, boosting feeding confidence 
  • Better visibility = fewer wasted pellets = better FCR 

The Result: More Growth, Less Feed 

Field trials show FCR improvements of over 9% when smart lighting is used. Multiply that by your feed volume, and it adds up to significant cost savings. 

Lighting isn’t just another piece of equipment; it’s a smart way to move your business forward.
