Humans have found a way to live almost anywhere. From ancient discoveries and early
innovations like fire and adaptable clothing to modern inventions like home HVAC
systems, our ‘technologies’ enhance our versatility. More importantly, we’re warm blooded—
meaning our bodies can physically adapt to varying climates.
Fish—like reptiles, amphibians, and insects—are cold-blooded. These animals can’t
regulate their own body temperature. Unlike us, they are unable to internally adapt to
environmental changes. Instead, they rely on movement and habitual adaptations.
FOOD & AIR
Despite our temperature differences, like us, fish need two things to survive: food and
air. As it relates to our fishing adventures, water temperature fluctuations affect these
core needs. In colder waters, fish slow down and need less food; in warmer waters, the
opposite is true.
The oxygen content of water also reflects the temperature. There is more dissolved
oxygen in colder waters and less in warmer waters. Let’s tie it all together—at a certain
point, as the temperature drops, fish won’t eat. And, at a certain point, as the
temperature rises, fish can’t breathe.
Now, we know the why of fish behavior. Let’s take a look at the how and when of our
on-water decision-making as anglers.
SEASONAL CHANGES
We can’t control seasonal changes, but we can know better what to expect. Here in
the Midwest, we’re fortunate enough to get all four seasons (and boy, do we get ‘em!)
In the spring, fish hang out closer to the surface—the lake’s equivalent of an orchard’s
‘low hanging fruit’. As the water warms up into summer, the fish need to regulate
during the hottest parts of the day (remember: they’re cold-blooded). So, at high sun,
the fish may move to deeper, cooler parts of the lake. Adjust accordingly. As we enter
fall, the fish instinctively know that a cold winter is right around the corner—potentially
triggering a frenzy of feeding. Take advantage!
EQUIPMENT SELECTION
We talked earlier about how the speed of fish changes with the temperature. Reflect
this in your lure selection. Slow moving lures like jigs and spoons are great for cold
water. Speedier lures like topwater and crank baits are better in warmer weather. Depth
matters too. The weight and color of lures are important considerations as fish control
their internal temperatures via the sun-soaked surface or the temperate abyss.
One last note, in warmer (or colder) than normal temperatures, the fish are already
stressed. Getting pulled from the water will only exacerbate their stress and likely kill
the fish. So, please remember to only catch what you intend to eat!
