Natural Light Mimicking LED Lighting Supports Sustainable Fishing

Adjustable LEDs that deliver light source similar to natural sun light not only help to improve human wellbeing but also enable sustainable fishing. Lighting supplier Signify announced that it is providing underwater LED lighting for the marine-based fish farms of Australis Seafoods in Chile. Australis chose Signify because of its commitment to a sustainable world, strongly supporting Australis’ objectives for responsible and efficient fish farming.

Signify’s underwater lights that reach up to 100,000 lumen, mimicking the summer sun, convert feed better aiding growth (better Feed Conversion Rate). As a result, less fish food is needed, leading to lower cost and cleaner water. The lights are submerged 5 meters deep, attracting the fish and dramatically reducing infections by sea lice who live closer to the surface.

Signify first installed its Philips aquaculture LED lighting in Australis’ Moraleda fish farm in Aysén, Chile. After achieving excellent results with them in terms of growth and Feed Conversion Rates (FCR), Australis asked Signify to upgrade the whole site. In addition, the site realized one of the best production results in Australis records and was named the best Skretting 2019 Fish farm in the XI region.

For several years, Signify has served in the Chilean salmon industry, providing its innovative photoperiod systems – that help to control the duration of light - to optimize salmon production. Atlantic salmon are very sensitive to changes in photoperiod - the period of daily illumination - in fresh and seawater, and particularly during the parr-smolt transformation (a series of physiological changes where juvenile fish adapt from living in fresh water to living in seawater).

Australis installed Signify’s photoperiod systems in most of its fish farms located in the XI Region of Aysén and is going to adapt the systems in the XII Region of Magallanes.

“Australis has always been open to try new things; technology, innovation, improvements. Especially in aspects related to production, we believe that they’re one step ahead, always showing interest, being analytical and making decisions based on real studies and tests. We believe that our mutual commitment to sustainable fish farming is very important to achieving a good collaboration. With Australis we’ve been developing as a single team, receiving excellent logistical and operational support in all areas and stages of the productive cycle,” said Bill Bien, Leader of Signify’s Agricultural Lighting Business.
