Fish activity tip

The fish activity algorithm is calculated based on solunar theory, tides and other factors. Tides create water movement that triggers feeding behavior, while solunar periods pinpoint optimal feeding times. Additionally, falling barometric pressure, signaling approaching weather changes, increases fish activity. Our fish activity algorithm combines these factors, assisting anglers in making informed decisions for more productive fishing trips.

"Minor" feeding times, occurring when the moon is at a 90-degree angle to the sun, also result in improved fish activity.
