  Mr Isbister is awaiting confirmation from the relevant authorities of its possible record-breaking status.
  The fish is currently being kept in his mother's freezer. "It was a very big fight," he said.
  He said he would keep trying to catch an even larger fish.
  He told BBC Scotland: "Muckle Flugga is renowned for big fish.
  "It took about 20 or 30 minutes.
  "I knew it was a big fish but I didn't realise it was that size - I am 6ft 5in and it's as big as me."
  Mr Isbister added: "It's in my mum's freezer. We had to make room for it, it fills the whole freezer.
  "I am a local celebrity at the moment."
