It is imperative to know how the meters work and that they are properly calibrated. A periodic check of DO levels is cheap insurance. Optimal DO for bass is typically in the 8-9 parts per million – levels below five parts per million can cause physiological duress.
In the absence of meters – making observations on fish behavior is an easy to way to get an idea of conditions in the livewell. If fish are lethargic, beginning to turn over and behave in a lackluster way then DO levels may be below optimal levels and precautions need to be taken.
DENSITY
Fish density and size are also factors. Maybe you can handle five solid fish no problem – but you are fishing a pro-am event and both anglers have separate five- fish limits or you have a team event with seven-fish limits.
This goes back to knowing your system and being observant of the conditions. If you know you might face one of those situations – and perhaps have large fish taking up considerable space, you need to be prepared in advance to regulate conditions in your livewell.
ADDITIVES
There are a variety of livewell additives out there; note, not all are the same and each have specific benefits. If you elect to use any livewell additives such as Rejuvenade, Fish Life, Sure Life, Fish Protector, PolyAqua, etc. etc. – it is good to understand what they are intended to do and not do.
For example, some formulas are specifically designed to removes nitrates, ammonia, chlorine, chloramines, and heavy metals, all while adding essential electrolytes.
Other formulations can include natural sedatives to calm and ease stress (I have mixed feelings about any sedatives). Others form a multi-layered protective slime coating on fishes’ skin, protecting fishes during handling and minimizing infection. The coating works as an effective healing aid for fishes with bruises, missing scales, or frayed fins. Having used a variety of formulations – I favor products that prioritize protection of the slime coat and remove toxins from water.
None of these products are a substitute for temperature, DO or fish density management; however, in my experience as a tournament angler and biologist, I have observed marked improvements in fish condition with use of certain commercial additives.
Remember – our goal is to keep fish as healthy as possible, and injury is not necessarily physically observed. Often most trauma is a result of physiological stress; thus, the more steps we can take to reduce any physiological stress, the better chance captured and released fish will have against any latent issues.
CLEANING
Lastly – it is important to regularly clean your livewells. Whether you are using a homemade concoction or specially formulated cleaner, it is a great idea to keep your livewell clean.
Residual chemicals, organics and other materials can affect the chemistry, function, and longevity of your components.
To ensure all perform optimally, it is best to clean and service them regularly. I recommend rinsing after each use and cleaning out any visual debris. Then periodically using a cleanser – there are several available on the market, just make sure they are non-toxic and they are used according to manufacturer instructions. •
