Re: Chub rule of thumb?
Chubs enjoy warm water, trout do not....During the colder time of year they co-hab, but when the water temp rise trout seek cooler water and chub live it up in the warmer water.
Other key info is chubs spawn in the early spring and trout cruze the spawing beds to catch a free egg meal.
I find that fish species tend to rotate in a spot. Fish in the AM and catch one species. Fish in the afternoon and catch another, fish in the evening and catch yet another kind of fish species....
