The challenge
In pond aquaculture, dissolved oxygen and water quality set the limit on stocking density, fish health and survival. Low oxygen and a rising organic load cost fish.
Researchers at Auburn University's Department of Fisheries ran a blind, placebo-controlled study to measure whether treating the water improved oxygen, water quality and survival.
What we did
Treated and control ponds were run side by side under a blind, placebo-controlled design, with dissolved oxygen, organic load and fish harvest and survival measured across the season.
The result
More oxygen, more fish.
The study declared significance at its own stated threshold of P=0.1, rather than the more common P=0.05, which is worth reading alongside the survival figures.
The study was conducted at Auburn University under a blind, placebo-controlled design and peer-reviewed, an independent, high-grade validation.
Why it matters
For aquaculture and any operator managing pond or process water, dissolved oxygen and organic load are the levers that decide survival and capacity. This independent study shows both can be improved, lifting fish survival, with the P=0.1 caveat read alongside it.
