Hickory shad will show by the end of March and the white shad will get there mid April. The really good fishing is from mid April til mid May, you can't have more fun with an ultralight. You can't keep them but they are a blast to catch and if you hit it right you can catch 100+ in a morning or evening, I am sure you could catch 250 in a day but they will wear you and your fishing reels out. They fight like a tarpin does - out of the water as much as in it.
