Optimal range 75-89°F

Well supportedWater temperature governs a cold-blooded fish's metabolism, so it is the largest term in the model (Christie & Regier 1988). The figure is a thermal-lag estimate built from forecast air temperature and the time of year — not a sensor reading, and not this lake's actual measured water.

Has no measurable effect on feeding activity

Well supportedLow-light feeding windows are the strongest timing signal inside a single day. How much each window is worth is this species' own cited response, sourced in its model file, not a generic curve.

Not supported by testingPeer-reviewed testing of North American freshwater fisheries found no significant relationship between solunar values, lunar phase or lunar illumination and catch rates (SN Applied Sciences, 2023) — air temperature predicted catch better than any solunar table tested. It is shown because anglers expect it, and it is shown separately so you can discount it. Its weight is under owner review.

Modeled flat — no change from this fish's baseline

ContestedThe barometric effect is real to most anglers but small and contested in the literature — several of the species studies cited in this model report null results — so it carries one of the smallest weights here.

Modeled about 10% below this fish's baseline

Moderately supportedWind stacks forage on windward structure, but both the size and the direction of the effect depend on the species and the water, so it carries a modest weight.
