Citizen science data at a scale and quality most research programs can’t produce themselves.
Anglers log simply by using their voice — on the water, at the dock, or on the drive home. Conditions are recorded automatically. Every opted-in trip contributes to the record.
Most fishing databases are one-sided — anglers only log success. That makes it nearly impossible to compute catch-per-unit-effort, the standard metric for tracking fish populations over time. The Ledger captures effort data including zero-catch days, because what didn’t bite is as scientifically meaningful as what did.

Bonefish & Tarpon Trust
Founding Conservation Partner
BTT is a leading organization dedicated to the protection and restoration of bonefish, tarpon, and permit and their habitats. Anglers who opt into the Ledger are contributing trip-level data — including zero-catch trips — that complements BTT's existing research programs.
We’re building conservation partnerships across the U.S. If your organization works to protect fisheries, we’d like to talk.
Partnership data access is provided at no cost to conservation organizations.
