Thread: Fishing during an algae bloom

Algae blooms are a natural part of the nutrient cycle, but they can make fishing tricky. During a bloom the dissolved oxygen level can swing wildly: by day the algae photosynthesise and add oxygen, but at night they respire and remove it. Fish will usually feed harder when the oxygen level is comfortable for them, often at dusk or through the night. When oxygen dips too low, it's kinder to leave them alone and alert the fishery so they can monitor DO levels. If you do fish, consider matching the hatch: switch to naturals like bloodworm or maggot hookers, or use small wafters/flavoured boilies to compete with the natural food. Setting up rigs that let you fish slightly off the bottom, like zigs or balanced pop-ups, can help when bloodworm beds are revealed. Above all, keep an eye on the fish – if you see them gasping or looking stressed, it's best to pack up and wait until conditions improve.
