Hi, I'm new to the site and am seeking some info regarding the mackeral species. I caught some last night off looe and when I gutted them their stomach cavities were full of tiny white worms that looked like they were living off the guts of the fish. I've decided to use them as bait rather then eat them. Basically I was just wondering if this is common and is nothing to worry about as I do enjoy a good mackeral on the barby! Cheers.
