I’ve found that most high lakes containing copepods have 2 things… big fish, and very picky fish. It seems like the fish aren’t as eager to take a fly or lure because they’re already super well-fed and not as hungry? I was curious if anyone has had any more successful tactics in lakes where these tiny red nutrient balls are present. I’ve still managed to trick some fish with a variety of flies, but it’s usually way more challenging than other high lakes with no copepods present. And the copepods themselves are so tiny, it doesn’t even seem worth it to try and tie a fly that small. I haven’t even seen a midge that small.
Anyway, figured it was worth asking since there’s such a good wealth of knowledge here!
