Uncommon Knowledge, Part 2

Part 1 presented some info on physical trout features, size, age, visual abilities, and some ways we might capitalize. Part 2 discusses body temperature, the language of motion, migration and spawning,

Trout Temperature

Like most other fish, trout cannot regulate their body temperature. Water temperature is vital to metabolism. Temperature tolerance ranges run between a couple of degrees above freezing up to around 77°F as an outside max. A realistic max of 65°F is generally accepted as the high stress threshold. So seeking the point in a river or lake where the forces of nature conspire to bring temperatures near optimal for your target species (mid- to high 50’s for rainbows, high 50’s to low 60’s for browns) can yield strike-rich results. They know where to go to find their optimal, hour by hour and day by day, and we should follow their lead.

Trout Language

In rivers, trout are very territorial; eating is the game, and all feeding stations are not created equal. Trout will often chase away others from their feeding lies and bolt holes. In lakes, by contrast, where there is no localized “preferred area” to defend, trout are less aggressive toward each other.
