Or is it Gerrick?!
Garfish, not the most common species of fish landed on the market at Newlyn! Garfish are found in the top twenty metres of water and can be caught off harbour walls, rocks and boats. They are often found swimming in shoals of mackerel.
They have a long thin eel like body with a beak (a bit like a swordfish). Oddly, when you go to fillet one you will find that they have green bones under their bluey back and silver belly. They are a good eating fish but the bones remain green after cooking which is off-putting but harmless!
Very often, anglers fishing from the North Pier in Newlyn find they have a fighting garfish on the end of their line when fishing for mackerel!
