Fishing Research Library
Every PrimeBite rating starts with published fisheries research. These pages show the drivers behind each species' 1-to-5 bite rating, the open-access studies they rest on, and — just as important — what we deliberately leave out when the evidence isn't there. We publish the evidence and the reasoning; the exact calibration stays private.
Freshwater
When Do Walleye Bite? What the Research Shows
A low-light fish whose activity peaks at dusk and dawn, shaped by light, season and a small moon nudge.
When Do Largemouth Bass Bite?
Dawn/dusk peaks, warm water, wind and season — and why barometric pressure is left out.
What Water Temperature Do Smallmouth Bass Bite Best?
A water-temperature-led rating, with an honest note on what we deliberately leave out.
When Do Northern Pike Bite?
Dusk-led, with wind and moon — and why there's no hourly chart for this fish.
Muskie — research & methodology
How PrimeBite rates muskie, the research behind it, and where the evidence is honestly weak.
Do Solunar Tables Actually Work? An Evidence Review
An honest, cited look at moon-and-sun timing — used as the fallback for unlisted freshwater species.
Offshore
Do Yellowfin Tuna Bite on the Moon Phase?
The moon question, plus the ocean signals — SST, chlorophyll and fronts — behind the rating.
What Water Conditions Bring Mahi-Mahi?
Mahi-mahi follow warm, productive water: the sea-temperature and chlorophyll evidence behind the rating.
What Conditions Turn On Black Marlin?
The moon, season and sea-temperature evidence behind the black marlin rating.
What Conditions Turn On Blue Marlin?
Bite conditions by region: full-moon in the NW Atlantic, none in the SW, plus temperature and season.
