Have you thought about going fishing lately? Why not try it yourself. You really dont have to be an expert if all you want to do is enjoy basking in the sun while holding your favorite fishing rod and waiting for your target specie of fish to tag your line. But you cant just go in the water and cast your line if you dont have the right knowledge, even just the basics of what you really need to do.
It is better to be safe at all times even if an activity means you will have a lot of fun doing it. Make an intensive research about fishing, the tools you need, the techniques in casting a line, fishing advices from fishing experts and experienced anglers and of course, learn the proper behavior while fishing. Consider yourself lucky if you are the only person who fishes an area of water, but chances are, you will be sharing it with another or two other anglers.
As for the different species of fish, they too need to be focused on especially when you are the type who really needs to know their exact location. You wouldnt want to waste your time waiting to catch a bluefish if you are fishing in an area full of flounders, would you? Know your preferences. Does salty water...
