Trout fishing requires so many different elements to be put in place to succeed in catching the fish. These elements are what fly to use, what rod, what bait, what the water conditions, weather conditions, etc.
One of these elements is trout fishing lures. There are so many different types of lures and they all have their own individual features, but choosing your lure comes down to how comfortable you are using it.
For example a spinner which is a lure imitates the movement of certain fish and act as prey for the trout you are after catching. Ideally you pick the spinner or lure that you feel will suit the water conditions and blend in well so it can help attract the trout.
Also you will need to think about the weight of the lure too. This helps with locating the fish during different seasons. For example if it was at the beginning of the season the trout would be near the bottom of the banks of the river due to just coming out of hibernation.
So ideally you are fishing at the beginning of the season you will need a heavier lure to help go nearer to the bottom so it will attract the trout's attention and hopefully get some takers.
What you should do is bring many different types of lures with you on your fishing trip, with different styles, weights etc. so you can swap and change when required to see what is working best for you.
At the end of the day you are there to catch trout, so you might as well find what is working best. Plus by swapping and changing and working out what is best for certain situations and circumstances, you will become a more experienced angler with a better catch record as you are working at what is best for you.
Another type of lure is a spoon, they are still a type of spinner but look like a spoon as the name poses. They move in a wobbling motion and they imitate small bait. They are a heavier type of spinner and are no more than an inch in size.
A popular lure being used is a rooster tail. They have attached to them a few pieces of animal hair which is meant to make them look similar to minnows when moving through the water, which is a prey that trout go for. The rooster tail will go to the bottom of the water and it will also stay at the top too, depending on where you want to fish. You need to fiddle with the rooster tail slightly to adjust the depth it works at. This kind of lure can be up to about 4 inches in size.
