I like to fish. I use many fishing tackles depending on what I am trying to catch.
I am intrigued.  What tackle would you use if you were fishing for brook trout?
Last time I fished for trout I used earthworms and crickets. They like those baits if I recall.
I suppose that is an excellent choice.  Earthworms are easily found in soil, and feed on dead or organic matter.
They are also pretty easy to grow for people who like to fish a lot. I usually just buy them at my local bait store.
You can grow them in your garden. Biturbation, or the reworking of soil was originated by Charles Darwin in his garden in the 1800's
