Because What’s More Important Than Temperature?

How do you tell a plant has root rot? It’s leaves begin to wilt. Old leaves and new leaves both just droop and fall off. Removing the dead leaves, moving the plant so it gets more hours of sun, building it something to climb on… none of these will help. Treating the symptoms - the leaves - will not help. The problem has to be dealt with at the roots. Repotting in barely moist soil, for example, may save the plant if detected early enough.

Water temperature is one of the “roots” of a fish farm. So many symptoms can pop up if temperature is not correct. Often they pop up as growth not matching the rates predicted in the business plan. If water temperature falls, fish eat less and grow slower… and rates of return also slow down.

Almost every other part of the RAS is sized based on a specific temperature. If water can not be kept cool, some fish may be more prone to disease, or may eat more while converting less feed to growth. Costs go up, growth may not.

So, if your temperature is not where it should be every day of the year, you need to fix this root issue first. Stop looking at the “leaves” of MBBR aeration pattern or solids settling rate or ozone dosage. All of that equipment will perform differently once temperature is correct. Strike at the root first.

If you have challenges with temperature control or capacity, talk with the only aquaculture engineer in the world whose specialty is the heating and cooling of fish farms. Having spent many years tinkering with heating and cooling systems at land-based farms, APS CEO Philip Nickerson now designs, builds and troubleshoots temperature systems in aquaculture.
