Ignore the conventional combo in pic.
I'm not the best explainer or most knowledge fisherman here, but I'll try my best and hopefully I'm correct with the information. Both spinning rods and (bait)casting rods are for bait fishing. Your spinning/casting rods will use a wide array of lures, rigs, baits, etc., to try and catch a fish. Fly fishing has it's own rods/reels that you buy that are totally different from spinning/casting rods.
There's 4 types of rods/reels you'll be seeing people fish with. >Spincast
Cheap and easy to use, but I don't think anyone that's not a child really uses them. I'm sure someone here does and will proceed to educate me on it's application, though. >Spinning
Extremely common reel/rod that anywhere from entry-pro level anglers are going to be using. It's super easy to use and cast so I recommend using it as a beginner to see if you actually like fishing. You should be able to find a cheap combo in Euroland to use for your river. You can do practically anything with it and should have no problems doing so. Whether you just want to worm fish or try using things like crankbaits. >Baitcast
A more difficult means of casting that's supposed to allow you to cast farther and more precisely. They'll be more expensive and difficult ot cast. They also have a slightly different rod structure from the other two since the eyes are on top of the blank instead of underneath. Basically if you want to try and enjoy fishing as a beginner, don't use a baitcaster.>Fly
Complete different rod used from the other 3 listed. I say completely because I have absolutely zero knowledge or experience with fly fishing beyond it appearing way more hands on than bait fishing. >>1905702
Do what this Anon said and figure out the type of mullet. Maybe ask some of the other fishermen in the area if they'll tell you. Make sure you let them know you're a beginner angler.
