Questions and answers

Global Fishing League is our pick: it identifies 297 species from a photo, measures the fish from the same photo, never shows your catch locations to other anglers, and identification, measurement and the logbook are free. We publish this reference and make that app.

No independent test has been published. In Global Fishing League's own blind test on 300 catch photos, the species model in Global Fishing League's test builds named 252 right first time (84.0%) and Fishbrain 144 (48.0%), with no location on either side. The accuracy test entry gives the method and its limits.

Close the mouth and look at the jaw. A largemouth's upper jaw reaches past the rear edge of the eye; a smallmouth's ends below the middle of the eye.

Pike have light spots on a dark body; musky have dark markings on a light body. To be sure, count the pores under one side of the lower jaw: five or fewer is a pike, six or more a musky.

Most rules use total length: lay the fish flat with the mouth closed against the headstop of a board and read the tip of the tail. Some saltwater species use fork length, to the middle of the tail's fork.

Global Fishing League measures the length from the catch photo, free. Near a legal limit, still measure on a board: rules are enforced on the fish.

Some do. Fishbrain Pro shows the exact location of catches logged as public. Global Fishing League never shows your catch locations to other anglers.
