Preparing to Clean a Fish

The first lesson is that the fresher the fish, the better the meat is going to be. Feel free to freeze prepared fish, but it begins losing taste as the meat dries and hardens. And your freezer can end up smelling like fish meat. That's a hard scent to get out.

Cleaning a fish is a bloody business, so try to utilize a park cleaning station. If not, try to find an outdoor table outside. Do the right thing and set down a liberal layer (or three) of newspaper under your prep station. Make sure you have access to a tap as you want to rinse the fish down before cleaning. And you’ll want to have clean, rinsed hands throughout the process.

Step 1: Rinse the oily coating off the fish as best you can.

Step 2: After you rinse the fish, use paper towels to pat it dry. You don’t want to be handling a lubricated body that you’re slicing with a sharp knife.

How to Scale a Fish

Running the fish under fresh, cold water will help to loosen its scales. After you’ve patted the fish down, lay the fish on top of several sheets of newspaper, which will assist in an easier cleanup.

Step 1: Take firm grasp of the tail and, using either a descaling tool or the blunt edge of a butter knife, run your tool from tail to head, scraping away its scales. After several runs, the torso should begin to feel smooth.

Step 2: Rinse the descaled fish side under running water to get rid of the residue and remaining scales.

Step 3: Carefully, run a finger against the grain of the fish to feel for any missed sections, watching out for sharp fins.

Step 4: Flip the fish over and repeat.


How to Gut a Fish

Step 1: Wrap up and toss out the scraped scales. Lay out another layer of newspaper and set the cutting board on top and your fish on its side. d to cook.

Step 2: Insert the knife tip into the fish's belly near the anal opening and move the blade up along this midsection, cutting to the head. Be careful to keep the knife blade shallow. Punctured intestines will ruin the meat.

Step 3: Spread the body open and scoop out the entrails. Find the fish's anus and slice in a "V" or notch shape. Make sure you remove the kidney as well. If the fish has one, the kidney will be higher up, near the backbone. Scrape it out with a spoon.

Step 4: Hose or water down the now cleared cavity out until you’re left with white or pink meat. Watch out for a dark tissue lining the abdominal cavity. Scour this out to avoid an overpowering oil in the meat. It’s your choice whether or not to cut off the head from behind the gills. Many game fish (trout in particular) are cooked with the head on. And if you can get to it, some of the fish’s most tender meat is behind its gills.

Step 5: Follow proper health protocols and clean your cleaning area. Collect and wraps the guts, heads, and scales in the newspaper, and toss them in a garbage can.

Now comes the fun part: your clean fish is ready to be dressed

How to Fillet a Fish

Now that you’ve got a clean fish, it’s time to slice it up into edible cuts. Fish fillets are one of the more versatile ways to fire up fresh fish.

Step 1: Place the fish with the dorsal fin facing you. Grab a sharp, flexible fillet knife to pierce behind the gills and pectoral fin.

Step 2: Cut down to the spine, but don’t sever it. Once the knife reaches the backbone, turn the knife flat and cut along and down the spine. This should create a flap extending from the fish’s head to its tail.

Step 3: Lift the flap with your non-dominant hand and continue to slice the fillet along the fish body, keeping your blade as close to the backbone as you can to maximize the meat. Be aware, but don’t freak if you cut into the ribcage — you can always remove rib bones later.

Step 4: When the cut is completely removed, place fillets down, skin first. Fried or grilled fish skin is a tasty snack or addition to your meal, so feel free to leave this on. If you’re so motivated, however, you can separate the fillet and the skin simply by sawing between the skin and the meat.

Step 5: Rinse with cold water, pat dry with a paper towel, flip and repeat.

How to Steak a Fish

Big game fish like tuna, salmon, or mahi-mahi deserve a beefier preparation. Steaking your fish not only gives you meatier portions, but you also get to skip what can be tedious filleting.

Step 1: Take your scaled and gutted fish back down and make a series of cuts perpendicular to the spine.

Step 2: Work from head to tail, chopping one-half and one-inch thick steaks.

Step 3: Trim away bones and fat from each cut, but leave the skin and backbone intact.

Step 4: Chop your catch into beef steaks, sear those puppies on the grill, and enjoy.

Tips And Warnings

Unfortunately, the human impact upon fish habitats makes learning about the environment where you’re fishing requisite.

  • Make sure that the fish you’re catching are safe to eat as mercury and heavy metal poisoning are common. State agencies and outdoor organizations are good places to research before tossing a line in the water.
  • Fish have natural protection as well. Watch out for sharp teeth, fins, spikes, barbs, and other appendages that can cause severe punctures or scrapes.

Thanks to your knife work, you've carved out a blank canvas from which to add any number of herbs, spices, zests, or marinades. Look to The Manual for ideas on how to dress and cook your quarry.
