Tips for Choosing the Right Size
When it comes to choosing the right size hook for rainbow trout, there is no one definitive answer. Instead, you’ll want to experiment with different sizes to see what works best for your particular fishing situation.
For example, if you’re targeting smaller rainbows near brushy cover, a smaller hook may be more effective than a larger one. Conversely, a larger hook may be preferable if you’re targeting larger rainbows in open water. The key is to experiment and find what size hook consistently catches the most fish in your area.
- First, take into account the type of fishing you plan on doing. If you intend on playing it safe by using a crankbait or worm, then go with a smaller hook. Conversely, if you’re looking for an aggressive fight with bigger lures, go with a larger hook.
- Use a chart to determine your fish’s weight and size. Check the dimensions of different hooks to see which one will fit your trout spinning rod comfortably.
What is the best bait for rainbow trout fishing?
There is a lot of debate on what the best bait for rainbow trout fishing is. Some believe that live baits are the best, while others feel that artificial lures are better. It all comes down to personal preference and what you think will work best for catching these fish.
Some good options for live bait include worms, small frogs or crayfish, and even small pieces of chicken or turkey. Artificial lures can be made from simple jigs to crazy-looking spinners and deep diving spoons. The key thing to remember is to find something that looks like something the trout would eat and that you can put in some subtle movements, so it seems alive.
I also recommend you do some research on the different types of lures available and figure out what is best for you.
Best Hook Size for Trout with Worm
Size 8 to 14 is the best hook for using a worm in trout fishing. A baitholder hook with two barbs on the shank is suitable for worms. It is helpful for live bait so it can move while staying on the hooks.
Trout Hooks for Powerbait
Powerbait is adequate to catch stocked trout. Most stocked trout are small in size, and you can use both single and treble hooks for Powerbait.
#8 to #12 size hook is best for the single hook. For treble hook, the range is #12 to #16. Use a smaller treble hook as trout’s mouth is small so that they can devour the bait.
Is a Size 2 Hook too Big for Trout?
Using the correct hook size improves bait presentation. Some larger hook size is 1/0,2/0,3/0, and 8/0. When using a bigger hook, a smallmouth trout won’t bait it because the hook is too big for them.
Also, a more significant hook can only be used for bigger bait. A size two hook is too big for the trout and will give a poor presentation in the water.
Different Types of Hooks for Trout Fishing
Single hooks are best for trout fishing. Some experienced anglers use special hooks for a specific type of bait. Some hooks are treble hooks, octopus hooks, circle hooks, etc. Double hooks can also use, but it is not that common.

Treble hooks can keep the Powerbait long time in the water. Also, you won’t lose the bait during the fight. Octopus and circle hooks are suitable for the short shank. And single hook can use for another type of bait.
The best octopus hooks size for trout is 8 to 12, and 10 to 12 is suitable for circle hooks. For treble hook, 10 to 14 size is better for trout fishing. Sometimes size 16 is essential when fishing trout in the creeks and streams. Barbless hooks can also use in trout fishing.
Best Hook Size in Clear Water
The hook size depends on water clarity. Like 6 or 8-size hooks, bigger hooks are suitable for dirty water as trout won’t see the visible hook. The smaller hook is best for clear water as trout can see it, so the hook must be concealed in the bait.
A 10 to 14-size hook is better. Suppose the current is slow, use 10 to 12 sizes. Use bigger sizes in faster current as they will be less likely to see the hook. A 6-size hook is suitable for faster water.
