Shad limit?

[Billfish715]

I just read the saltwater compendium and noticed the possession limits for American Shad. If I read it correctly, a person may only possess 3 shad from the Delaware River and its tributaries and 6 anywhere else. The freshwater compendium regulations also indicate a limit of 3 but state that no other shad can be taken from anywhere but the Delaware. I guess that applies to the Raritan. The excuse for poor shad returns years ago was the pollution block in the lower river. What's the reason for such poor returns now?
