Ideal Fish is proud to be the only US producer of branzino, otherwise known as sea bass and a niche product among American consumers, which Ideal Fish rears in a recirculating aquaculture system (RAS).
Ideal Fish was formed in 2013 with the aim of supplying US consumers with locally produced, fully sustainable, transparent, high quality fish free from hormones, antibiotics or chemicals, and eliminating the carbon footprint that is inevitably part of importing sea bass from Europe.
As fish grow and are transferred to larger volume tanks, the increased biomass inevitably results in a higher volume of waste, further increasing the loading of suspended solids and dissolved nutrients both in the tanks and in the general system itself.
Ideal Fish went to disinfection aquaculture experts at Evoqua for an efficient and economical disinfection solution to help remove the water impurity loadings and create a better more biological efficient system for the fish to grow in.
Ozone is a highly oxidizing gas that can remove farm water impurities such as organics, pesticides and nitrites, while reducing discoloration/tannins, enabling the fish to remain healthy throughout the farming process. The micro flocculation of fine solids created by ozone is also of importance in this application, as it will improve the farm’s particulate removal efficiency via their filtration process.
Ozone will also change the characteristics of dissolved organic compounds (DOC) by oxidation and precipitation, making it easier to remove DOC by biofiltration and sedimentation. Evoqua’s disinfection team provided one MNG8X34 Ozone Generator to meet the needs of Ideal Fish.
Using an exclusive smart ozone module chassis design, MNG series ozone generators deliver production rates to 1.4kg/hr with programmable operating modes in 70g/h increments, while maintaining full resolution control and automatically adjusting feed gas flow rates for full efficiency and ozone production optimisation. The MNG Series ozone generators also feature Powertron technology, a novel power supply design which provides a new method of control power for precision O3 output, using less energy. This innovative technology provides Ideal Fish with a quieter, stabler, and more efficient solution.
After some months of use, the Ideal Fish saw a definite increase in water clarity and fish performance, enabling them to further increase the growing and performance parameters with controlled and precise use of the Ozone facility.
“Ozone disinfection is a mission critical process in RAS aquaculture,” said Ideal Fish President and CEP Eric Pedersen.
“Water quality, bacterial load management and fish health are all highly dependent on a well-designed ozone generation and delivery system. Our Pacific Ozone system does all this for us while, by increasing our re-circulation rate, allowing our operations to be more environmentally sustainable.”
