When im using a texas rig with a artificial worm, after i catch a fish will the worm be reusable or no?

yes more than one bass should be able to be caught with just one worm because usually after a bass is caught the worm will just slide on the hook either up or down

It mainly depends on how aggressive the fish are being. Sometimes I can catch several fish on a single worm, while other times, I'll go through 15+ in a single day of fishing. Some worms are more durable than others as well. I personally mainly use Culprit and YUM branded plastics, and they are both pretty durable; although, there are days when fish will simply tear them apart in not time at all. I do highly advise staying away from the YUM Dingers, though. They catch fish, but they get tore up very easily. Strike King has a great, durable stick worm that catches just as many fish and by far outlasts the Dingers.

Yes, and then if it's torn you can fix it with a lighter and a butter knife. Just hold the butter knife over the flame until its hot enough to melt the plastic, then melt the plastic on the inside of the tear and hold it together until the plastic hardens. That's what I do, saves me alot of money.

Yes. You can usually catch multiple fish on a single worm before having to replace it.

yes it will be fine to use
