KEEN angler Kerry Foster caught one of the biggest bream he has ever landed in the Eli Waters canal.
He reckoned it would have tipped the scales at well over one kilogram.
The problem was part of the weight belonged to a sizeable growth just behind the gills.
"I was disappointed but I didn't want to eat him with that on him," Mr Foster said.
A representative for Hervey Bay Vet Surgery said there was no reason for alarm.
"Fish get tumours and cancer from time to time just like cats, dogs and people," the representative said.
"It could also be an abscess from something like a hook."
