In order to go fishing you need a rod & reel and some basic tackle. There are several kinds of rod & reel for either spincasting (best for beginners) or for fly fishing. You can buy these separately, or in combination. You need to select your line to suit your fish and your rod & reel, though today monofilament made of a single strand of plastic is most prevalent. The "terminal tackle" at the fish catching end of the line may include any of a number of elements: the hook for bait or a lure, a snap swivel (particularly when using spinning lures), a sinker (to hold the hook down), a bobber (to keep it up, say above weeds). You will also need a tackle box, needlenose pliers, nail clippers, a bucket, a net (for landing the caught fish), and optionally a camera.
The choice of bait or lures depends on what you're fishing for, the time of year, your fishing philosophy, and sometimes local rules. Typical live bait includes earthworms, minnows and assorted garden "crawlers." Lures tend to be more expensive, but present several advantages: they are durable, you can pre-pack a variety to suit any fishing excursion and they are heavier making it easier to cast in windy conditions. Some of the accessories to help make your fishing trip safer and more fun include: hats (for shade), sunscreen, insect repellent, life jackets (absolutely when fishing from a boat, but also for kids along the shore), a first aid kit, and waterproof boots or waders.
