Water sets the situation. Species behavior explains it. Presentation follows from that relationship. It isn't a product ranking.
How this works
You get the reading first. The app may then ask one high-value follow-up only if changing that answer can materially change the result.
1 · Target
What are you fishing for?
2 · Water
What kind of water are you on?
Geography helps with context and regulation checks. It never silently assigns a population profile.
3 · When · optional
When are you fishing?
Season is set from 2026-09-16. Change it if that doesn’t match the water.
4 · Water temperature · optional
What do you actually know?
Pick a species and the kind of water you're on to start.
Choose how much of the chain you want to work
Water →Species→ Season → Holding water → Forage → Presentation → Tackle
Your pathway changes how much is shown, not the biology. None of them adds a bite score or a hotspot. This app doesn't have those.
Decision map
Every recommendation has to survive the chain
The analyst does not jump from a fish name to a lure. Each link constrains the next one. Unknowns stay unknown, and a downstream recommendation cannot quietly repair a missing upstream fact.
How each declared input changes the decision
Declared input
What it is allowed to change
If you do not know it
Water type
Which holding-water vocabulary and current/tide logic are valid.
The analyst will not invent river, lake, surf or offshore geometry.
Season + temperature
Species position, thermal context and whether a presentation assumption needs caution.
Season can remain open; temperature can be exact, a range, or unknown.
Holding water
Depth, current relationship, cover and the delivery geometry a presentation must solve.
The result exposes the missing observation instead of turning it into a score.
Forage
Prey mode, profile and the presentation families that can plausibly imitate it.
Reviewed diet remains evidence, but observed forage is never fabricated.
Light, clarity, flow / tide
Tie-breakers inside an already plausible family: visibility, pace, depth control and angle.
An undeclared condition contributes no weight.
Presentation family
The tackle and connection requirements needed to deliver it cleanly.
The app offers the next defensible family rather than a product recommendation.
This is a map of the engine's evidence flow, not a promise that every declared fact will change the answer. A fact only matters when the reviewed species record and presentation model give it something defensible to change.
Field school · reviewed video
See the mechanics, then come back and make the decision
These are supplemental demonstrations from established instructional channels. They teach water-reading and presentation mechanics; they do not override the sourced species record, current regulations, or the analyst's uncertainty language.
Popularity counts are a review-time quality signal, not a permanent score. They are dated so the next content review can re-check the link, channel, usefulness and audience response instead of pretending a video recommendation never ages.
