Now here is a fellow that is very lively in the cold spring water and is very tasty but many ignore. Simple #6 hook and worm with a small split shot sinker. You will haul them in by the basket.
Avoid these fellows in the warm water though as the flesh is soft and often full of worms.
Have you ever tried them?
The do give a god fight in the cold water and are a great item for small children.
