When using a fish finder to identify fish, look for arches or fish symbols on the screen. Fish arches are typically displayed as curved lines that represent fish passing through the sonar beam. To distinguish fish from other objects, pay attention to the size, shape, and movement of the signals. Larger arches usually indicate bigger fish, while smaller ones may be smaller fish or baitfish. Fish symbols, if available on your fish finder, can make it easier to identify fish as they directly represent the presence of fish. Additionally, consider the depth at which the fish are located, their behavior patterns, and the surrounding underwater structure to make informed guesses about the type of fish you are marking.
