State-of-the-art land-based salmon production facilities naturally require state-of-the-art lighting. That means lighting that supports fish throughout the growth cycle, via light recipes that optimize light levels, spectra, uniformity, and duration. The right lighting regime is crucial to indoor aquaculture. It promotes healthy feeding habits, establishes steady circadian rhythms, improves feed conversion rates, supports growth and more. The long photoperiod suppresses the trigger to mature. This is necessary as mature fish in nature return to fresh water and spawn, negatively influencing taste and cutting harvest weights because the salmon is no longer edible.
“Lighting hardware needs to withstand damp and otherwise challenging conditions. It also needs to be designed so as not to encumber the free circulation of fish - even as it illuminates the entirety of the tank, no matter how many fish that tank contains or how turbid its waters may be,” said Roar Ristesund, key account manager aquaculture lighting at Signify. “With the possibility to upgrade the control system through the intuitive interface, the tank- and site-specific lighting commissioning and scheduling services can be managed easily.”
Supporting food availability through aquaculture LEDs illustrates our commitment to supporting good health and wellbeing (SDG3). This is key to our commitment to doubling the percentage of our revenues for brighter lives, which benefit society, to 32%. This is part of our Brighter Lives, Better World 2025 program, which we launched in September 2020.
