Fish Sticks Stream Fishing In Yosemite?

Fishing in yosemite? - fish sticks stream

i dont think i need a license, because I am under 18, but I need advice on fishing. I'll be camping in Yosemite and finally stream / fishing is in flux. I have a rod ugly stick fishing tackle some random, but I need something to guarantee that the catch. is open (I forgot what their names are, but the strings are not included.) I have an experience in fishing for mackerel in saltwater.

In the current next week (July) and really need advice on bait to buy, etc. .. i dont care what i catch fish, if I can get something (I can not go fishing all day) thank you!
