..."When keen young angler Josh Boyle felt a pull on his rod, he was expecting the usual roach or Rudd."
Read on a bit further and it says...
..."landed his catch with just a spinner on his rod"
Now Josh sounds like a kid that knows what he's doing so I doubt he made the first comment to the mail. He probably told them the complete opposite and that he was expecting a pike of perch to take his spinner.
Reads to me like the Mail writer is the one that knows very little about angling and as you say Paul they like to spice it up a little.
