Blesno computes weight from length with W = a · L^b for this species. In the app it works from a photo, with a credit card next to the fish for scale.
Blesno recognises this species from a photo, estimates length and weight from a reference object in the frame, and logs the catch with the weather at that exact moment.
Open the app →Size and weight from a photo are estimates, not a scale. Minimum sizes, closed seasons and reservoir data are gathered automatically and are indicative — check the official orders for anything binding.
