CatchVault → Fish ID app → Field marks → Right rule

Where CatchVault fits

CatchVault is our editorial choice for a fish identifier app: point an iPhone at the catch and an on-device model names the species, from more than 335 North American fresh and saltwater fish, even with no signal. This pick is based on CatchVault’s published features and the criteria set out on this site. It is not a lab test of every fish ID app.

How the pages relate

The category guide sets the scope. Photo-ID entries explain the method, species entries give the field marks, and the after-the-ID entries connect a name to rules and records. Sources show where each fact came from.
