As our over-heated Summer slips by into a hopefully cooling down Autumn (El Nino permitting, I must add), we enter a period that traditionally has become known in fishing folklore as the “big fish” months.
Why this is so should not be problematical to understand, even though conventional fishing wisdom has it that during periods of changing weather patterns fishing can be not good at all as fish adapt to different day and night temperatures and periods of sunshine. But in practice Autumn has delivered many PB’s to a great many anglers. After all, as fishery biologists will tell you, the bigger fish hive off into the deep where temperatures tend to be more stable than in the shallows where there are significant differences between day and night temperatures. This is a truism for just about all freshwater species. So it happens that the small fish become less active while the big ones must maintain their food intake.
