I got a question about catching Large Mouth Bass on a fly.  I have on fly rod that I originally bought for trout.  All I know about it is it is a berkley it is 7'9'' and it says line number 5-6.  Not sure what that means but maybe someone else will know.  What I am wondering is what kind of flies or lures can i use with this rod to catch bass?  I hear people talk about bass bugs.... what are they?

Bass bugs are in many cases larger versions of the same lures one uses for trout and panfish. I had (and lost) lures my dad had, a large palmer tied red an white fly and a large "bee". I still have most of his old "'Poppers". Goggle up "bass bugs" and you will get tons of links. Your rod might be considered light for bass but try Muddler Minnows- wet or dry, Wooley Buggers, streamers and so forth, all sized to your rod, probobly up to #4's. Heavier leaders than use for stream trout are probobly appropriate.

A 5/6 weight rod would be fine for sunfish, but for bass I wouldn't go lighter than a 7 weight, some people go as high as 10 weight. I use a 5/6 for sunfish and a 7 for bass.

I disagree. A 5/6wt should be fine for bass. Unless you'll be catching 5+lber's, you'll be all good. I've caught 2-3lber's on a 4wt without any problems. The smaller weight will limit the size of flies you'll throw, but you can still catch nice bass on smaller bugs.
A "bass bug" can be anything from a mid to large sized popper to a spun hair bug. With your 5/6wt you should be able to throw a wide range of bass flies. Aws AZAllen said, Google "bass bugs" or "bass flies" and you will get a good idea of what you can use.

Okay thank you very much. So the 5-6 is the weight of my rod but what does that actually tell me?

Flyrods are determined by weight of line, like a spin rod is determined by power (ultra light, light, medium...).
You wouldn't want to go fishing for pike on a ultra light spin rod(or you might). Just like you wouldn't go after pike with a 2wt flyrod.

Your 5/6 fly rod is rated for 5 or 6 weight fly line. The rod and line must match up to cast properly. It is possible to go up or down one weight in line for the rod rating, but casting will suffer to a degree. Best to stick to the correct line rating for the rod. You need heavier rated lines ( rods) for casting larger, and heavier, flies. Most bass bugs, poppers, Klauser minnows, etc. are too heavy to cast with a 5/6 weight. Sure you can catch bass on smaller flies, but you will get mainly sunfish as they are insect feeders ( which the small flies imitate) . Bass prefer larger forage such as small fishes, crayfish, frogs, mice, etc. which the larger bass flies, bugs, poppers, and Klauser minnows imitate. For flies of this size and weight you will need at least 7 weight.

Okay I Understand thanks a lot for the info.

The size of lure you can use is based on what your line will turn over, I guessed at #4 size flies like muddlers and wooly buggers as sizes that you might be able to handle. I would say try the rod you have now and then perhaps upgrade to a 7/8 if/when you feel that it is appropriate. Go back in the thread and look for other links, the book the rod tosser suggests is probobly very good, I hae been impressed with the links he has provided in the past.

there are a ton of flies you can use . think what do bass eat . Leaches , frogs, mice, other fish , craws, then try to imitate it with a fly .
some good fish imitations would be , Clouser minnows , muddler minnows ,
some frog imitation may be poppers and dahlburg divers .

a woolly bugger could be a bug, fish, craw, leach , they are just a darn good pattern .
