Kessil's Tuna Blue Helps Grow Bluefin Tuna

November 11, 2014

Something lurks in our oceans. Weighing in over 1,000 pounds at over 6 feet in length, this creature is a true leviathan. With its massive, streamlined body, it torpedoes through the open ocean at a top speed of over 40 miles per hour. This is the bluefin tuna. Its reputation on land is no less impressive; it is a prized delicacy that can fetch over one million US dollars for a single fish. It is so sought after and over fished that the entire species is now threatened.

Yet, this controversial giant starts, as great things often do, from humble beginnings. Smaller than the width of a fingernail, the bluefin tuna starts its life as an awkward bug-eyed larva. One team, led by Dr. Yonathan Zohar, has taken on the challenge to raise these helpless larval bluefin tuna. Their basement lab at the University of Maryland Baltimore County is full of huge cylindrical tanks filled with translucent hatchings. Utilizing extensive aquaculture experience in everything from blue crabs to salmon, Dr.Zohar's group is the first team of US scientists to successfully raise these delicate larvae under lab conditions.

To achieve these results, the scientists must meticulously replicate a natural ocean environment. The water condition, the food supply, and the lighting – everything has to be perfect. When it came to the lighting, Jorge Gomezjurado, a scientist on Zohar's team, immediately turned to Kessil. He knew that the spectrum and the shimmer would most closely mimic the natural sunlight on the open ocean. With the color tunability and intensity adjustment, they would be able to further refine the full spectrum light. Linked together with a Spectral Controller, the set up proved to be simple and cost effective.

The path to discovery is long and difficult, but overcoming those challenges can create something truly priceless. As a technology company on the forefront of innovation, we recognize Dr. Zohar's effort in pioneering bluefin tuna aquaculture. We are deeply honored that we were chosen to participate in this groundbreaking project to help save the magnificent bluefin tuna.

About Kessil ®

Kessil Lighting designs and manufactures innovative LED lighting products for the horticulture and aquarium industries. Kessil is a business division of DiCon Fiberoptics, Inc., a leading technology company for over 25 years in the photonics industry. Using DiCon's patented high power Dense Matrix LED™ platform, Kessil's products emit a powerful, penetrating beam of light. Each LED chip produces one wavelength, allowing various spectrums to be created by grouping different types of LED chips together. As a result, Kessil can populate chips with specific wavelengths onto DiCon's array. For this purpose, Kessil's research team continues to rigorously search for different spectrum recipes to enhance coral and plant growth. With this constant quest for the best spectrums, Kessil is leading The Spectral Revolution®.
