Shad larger than 6 pounds caught in the Delaware are 2nd run fish .

Fish we see yearly are approximately 5 years old .
Fish that are larger are 7 to 8 years old making a second spawning run .

IMO the river is so much cleaner now the fish run further , and most don’t make it back to the ocean to return again 2 years later ..
