I work at a hotel in Pondoland near the Wild Coast in South Africa, which is a couple of
minutes walk away from the beach and we are fortunate enough to have a ready supply of
fresh fish from the local fisherman.
This is the tale of me turning a whole fish ( a 5kg Steenbras) into fillets which where then cut into
220g portions to be grilled and served at supper to our guests that night.
(Unfortunately my brain works in metric, hence the measurements)
Step 1: Slicing Behind the Gill Plate
spinal column and the through the belly.
Step 2: Starting to Loosen the Fillet
then on the upper side of the fin from the tail to the body cavity, all the way to the spinal column
Step 3: Loosen the Fillet (part Two)
Following the top fish, slice from the "neck" cut, along the bone till the tail.
When you get to the ribs (second picture) you'll need to cut through them to free the fillet
I either use a knife, as in the third picture, or on larger fish, a pair of pruning shears I keep
specifically for this purpose ( if it cuts through 20mm diameter branches, it will happily go through thinnish bone)
Step 4: Now What?
or flip it over and remove the other fillet and then remove the bones.
Step 5: Final Result and Other Stuff
with meat on.
I normally boil the carcass with onions, carrots and bay leaves until it cooked and have one of
my staff strip off the meat for soup (use the stock you cooked it in) but thats a story for another day.
For the inquisitive, I get about a fifty five percent yield of fillet off a fish, and then about fifty percent
of the carcass ends as cooked meat so its pretty economical to do this.
