Please note that when temperatures are high, we advise
No Salmon fishing when the water temperature is above 19.0°C
No Trout or Pike fishing when the water temperature is above 20.0°C
No Coarse fishing when the water temperature above 25.0°C
As the temperature rises the amount of oxygen water can hold decreases. This affects the ability of fish to recover from being caught. Above the temperatures listed above mortality rates post capture increase exponentially. This is why at these temperatures it is always worth taking a thermometer with you when fishing
