Dissolved Gas Management in Fish Hatcheries: A Case Study
The VAL™ continuously removes undesirable dissolved gases from hatchery water through fine bubble gas exchange and vacuum extraction. If left in the water stream these gases dramatically decrease the survivability of the fish hatchlings and fingerlings. By injecting oxygen into the processed water stream, the dissolved oxygen level is raised to the level needed to ensure healthy and energetic fish fry.
A VAL 600™ recently installed at a western US fish hatchery achieved the following dissolved gas results:

After installing the VAL™, the hatchery reported that the survival rate of their triploid walleye hatchlings increased by a factor of 5.3 and the survival rate of their diploid walleye hatchlings increased by a factor of 2.6. The hatchery coordinator noted that “This will make a huge difference in our sterile walleye program."
