How to Fillet Sea Bass Complete Guide
Learning how to butcher and fillet whole sea bass

Learning How to Fillet Sea Bass Complete Guide is one of the most rewarding skills in classical seafood preparation. Purchasing whole fish and fabricating them in your kitchen saves money, guarantees freshness, and yields delicate skin-on fillets as well as flavor-packed carcasses for stock.

For beginners, sea bass is the ideal round fish subject for learning fish butchery. Sea bass feature a sturdy central spine, large accessible rib cages, and firm white muscle tissue that resists tearing during filleting. Round fish yield two distinct, symmetrical side fillets that are straightforward to isolate with a flexible blade.

This comprehensive step-by-step guide is written specifically for beginners. You will learn about the specific sea bass species this guide applies to, understand species-specific butchering modifications, evaluate whole fish freshness, scale cleanly without making a mess, gut the cavity safely, execute the classic three-cut filleting method, pull pin bones with precision, skin fillets smoothly, simmer a light French fish fumet (stock), and pan-sear sea bass for perfectly crisp skin.

Wine Drop Cookery focuses on connecting quality ingredients with precise culinary execution. Mastering whole fish butchery eliminates seafood waste, builds blade control, and elevates home fish dinners to classical restaurant standards.

Whole Fish Principle: Responsible seafood butchery means using every clean section of the fish, from prime center-cut fillets and crispy skin to collagen-rich frames for delicate white fish stocks and sauces.

Beginner Fundamentals: Understanding Sea Bass Fabrication

Before picking up a knife, beginners must understand the specific species of sea bass available in retail fish markets and the anatomical orientation of round fish.

1. Types of Sea Bass Covered in This Guide

The term sea bass broadly encompasses over 475 different species across the Serranidae family and related marine fish families worldwide. While over 475 species exist globally, this guide covers just a few of the most common primary culinary species available in retail seafood markets:

  • Black Sea Bass (Centropristis striata): Native to the Western Atlantic and North American East Coast. Typically sold whole between 1.5 and 4 lbs. Features dark scales, white delicate flesh, and sweet flavor.
  • European Sea Bass / Mediterranean Branzino (Dicentrarchus labrax): The premier culinary round fish of the Mediterranean and Atlantic. Widely sold whole in markets weighing 1 to 3 lbs. Known for silver skin and flaky white meat.
  • Striped Bass (Morone saxatilis): Found in Atlantic coastal waters, estuaries, and aquaculture facilities. Ranging from 3 to 8 lbs whole, featuring dark lateral stripes and firm, rich flesh.
  • White Sea Bass (Atractoscion nobilis): Native to the Pacific Coast and California waters. A larger croaker/bass species yielding thick, firm white fillets.

Note on Chilean Sea Bass: Chilean Sea Bass (Patagonian Toothfish) is a massive deep-water Antarctic species weighing 20 to 100+ lbs. It is almost always sold pre-fabricated into large commercial subprimal steaks or loins rather than whole round fish.

2. Round Fish Anatomy: Why Sea Bass Is Ideal for Beginners

Round fish feature an oval body shape with a central vertebral column running down the middle, flanked by two thick side muscle slabs (fillets). The rib cage curves outward from the spine to protect the internal organ cavity. Because the bone map of sea bass is symmetrical and substantial, finding the skeleton with your knife tip is easy and predictable.

3. The 4 Golden Rules for Beginner Fish Butchery

  • Keep Fish Icy Cold (32-34F): Warm fish flesh is soft, fragile, and tears easily under blade pressure. Cold fish flesh remains firm, allowing clean, smooth cuts.
  • Let the Bones Guide Your Blade: Never force or chop through fish bones. Keep the flat side of your filleting blade pressed firmly against the backbone so you feel the blade ride along the rib structure.
  • Use a Razor-Sharp Flexible Blade: A dull knife crushes delicate fish muscle cells and tears skin. A sharp, flexible filleting knife bends slightly to match the contour of the bones.
  • Wipe Your Work Surface Continuously: Fish scales and protective surface slime reduce cutting board friction. Keep damp paper towels nearby to wipe your board and knife clean between steps.

4. Realistic Yield Expectations: Whole Fish vs. Fillet Weight

Whole fish yield varies depending on head size, gut fullness, and bone density. A whole 2.5 lb round sea bass typically yields roughly 40% to 45% boneless skin-on fillet weight (approximately 1.0 to 1.1 lbs of pure fillet meat). The remaining 55% to 60% consists of the head, backbone, tail, and viscera. Saving the head and frame for fish stock ensures that almost 80% of the total fish weight provides valuable culinary use.

Species-Specific Butchering Variations Across Sea Bass Types

Species-specific butchering variations across sea bass types

While the core three-cut filleting method applies to all round fish, different sea bass species feature distinct structural variations that require subtle knife adjustments during fabrication.

1. Black Sea Bass: Managing Sharp Spines and Firm Fillets

  • Fin Trimming Caution: Black Sea Bass feature exceptionally rigid, needle-sharp dorsal and anal fin spines. Snip off all fin spines with heavy kitchen shears prior to scaling to prevent painful puncture wounds.
  • Thick Scaling Required: Scales on Black Sea Bass are thick and deeply embedded. Rake your scaler underwater using short, forceful strokes, paying special attention to the collar and belly seams.
  • Firm Flesh Resilience: Muscle tissue on Black Sea Bass is firm and forgiving, making it an excellent choice for beginners practicing smooth single-pass knife cuts.

2. European Sea Bass / Branzino: Handling Delicate Ribs and Thin Skin

  • Light Blade Pressure: Branzino feature delicate rib cage bones and tender muscle fibers. Apply lighter downward pressure with your filleting knife when riding over the rib cage to avoid slicing through rib bones into the fillet.
  • Preserving Thin Skin: Branzino skin is thin, delicate, and highly prized for pan-searing. Keep skin intact during scaling to prevent tearing the paper-thin skin layer.
  • Pin Bone Size: Pin bones in Branzino are thin and flexible. Pull them with pin bone pliers using a gentle, steady motion to prevent snapping the bone tips inside the flesh.

3. Striped Bass: Navigating Heavy Bones and Lateral Blood Lines

  • Stiffer Blade Selection: Large Striped Bass (4 to 8+ lbs) possess thick, rigid backbones and sturdy rib cages. Use a slightly stiffer 7 or 8-inch filleting knife rather than a thin flexible blade to maintain cutting control against heavy bones.
  • Lateral Blood Line Removal: Striped Bass develop a prominent dark red blood line running along the central lateral line of each fillet. This dark muscle contains strong oil reserves. V-cut or trim away the dark red blood line with your boning knife to ensure a mild, clean flavor profile.
  • Thick Collar Extraction: Striped Bass feature large, meaty collars (jowls) behind the gills. Cut out the collar section whole for high-heat grilling or broiling.

4. White Sea Bass: Processing Large Pacific Primals

  • Belly Membrane Trimming: Pacific White Sea Bass feature thick belly flaps with dense membrane lining. Trim the lower 1 inch of thin belly flap off the fillet and reserve for ceviche or tacos.
  • Large Pin Bone Extraction: Pin bones in White Sea Bass are larger and firmer. Grasp bones securely near the root with heavy-duty pliers and pull firmly in the direction of the head.

5. Chilean Sea Bass: Subprimal Loin Portioning Techniques

Whole Chilean sea bass
  • Subprimal Loin Fabrication: Because Chilean Sea Bass (Patagonian Toothfish) arrive as large, deheaded, and gutted loins or subprimal slabs (weighing 10 to 30 lbs), filleting from a whole backbone is not required.
  • Thick Cross-Cutting: Place the subprimal loin on your board skin-side down. Use a long slicing blade to cut crosswise into thick 1.5 to 2-inch portion steaks. A 13.5-inch flexible Damascus fillet knife reaches across a large loin in one stroke, which is what keeps the cut face clean.
  • High Oil Content Handling: Chilean Sea Bass contains high natural omega-3 oil reserves. Keep loins near freezing (32-34F) during slicing to keep fat firm and prevent portion distortion.

Essential Seafood Safety, Freshness Indicators, and Sanitation

Seafood freshness is paramount. Delicate fish proteins spoil rapidly if kept above freezing temperatures.

1. How to Identify Ultra-Fresh Whole Sea Bass

When purchasing whole sea bass at fish markets, evaluate these five key freshness markers:

  • Eyes: Clear, bright, shiny, and bulging. Avoid fish with cloudy, sunken, or red-tinted eyes.
  • Gills: Vibrant deep red or pink color with clean wet surfaces. Avoid brown, grey, or slimy gills.
  • Flesh Elasticity: Firm and springy to the touch. When pressed gently with a gloved finger, the flesh should bounce back immediately without leaving an indentation.
  • Skin and Scales: Shiny, iridescent skin with scales firmly attached. A healthy protective clear coat of slime is natural, but thick, milky, sticky slime indicates age.
  • Scent: Clean, fresh, ocean-salty aroma. Avoid fish with harsh ammonia or sour odors.

2. Ice Management: The 32F (0C) Cold Chain Standard

Store fresh whole sea bass directly on crushed ice inside the refrigerator (32-34F / 0-1C) prior to processing. Ensure drainage holes or perforated pans allow melting ice water to drain away, as sitting in standing freshwater softens fish skin and degrades muscle texture.

3. Workplace Sanitation and Fish Slime Management

Rinse whole sea bass under cold running water before placing them on your cutting board. Scrub boards with hot soapy water and sanitize surfaces with a food-safe solution after handling raw fish.

4. Safe Internal Cooking Temperatures for Sea Bass

The FDA recommends cooking finfish to an internal temperature of 145F (63C), where the flesh becomes opaque and flakes easily with a fork. (Note: Many culinary chefs pull sea bass at 135-140F to serve moist, tender fillets.) That gap is narrow enough that guessing costs you the fillet, so use a digital thermometer with a long probe rather than judging by eye.

Beginner Equipment Checklist: Tools for Fish Fabrication

Filleting knife, shears, scaler, and pin bone pliers laid out for fish fabrication

Having the proper specialized tools makes scaling, gutting, and filleting sea bass effortless.

1. The Core Cutlery Tools: Filleting Knife and Shears

  • 6 or 7-inch Flexible Filleting Knife: Featuring a thin, narrow blade with flexible spring steel that bends around backbone curves. On a 2 lb branzino a shorter blade gives you far more control than a long one. Our 8-inch Damascus fillet knife with a blue resin handle ($159) is the closest fit for fish this size, and the 11-inch curved fillet knife with a rosewood handle ($120) suits larger striped bass and white sea bass.
  • A Stiffer Blade for Big Fish: Striped bass over 4 lbs have heavy backbones. The Scandinavian fillet knife with leather sheath ($179) carries more spine than a thin flexing blade, which is what you want when the frame fights back.
  • Heavy-Duty Kitchen Shears: Essential for snipping off sharp spiny dorsal fins, pelvic fins, and tail tips safely.
  • A Heavy Blade for Frames: Chopping a head and spine into stock-sized pieces is not fillet knife work. A 14-inch high carbon steel butcher cleaver ($199) goes through frame bone in one stroke instead of three.
  • A Sharpener: A dull edge is the single most common cause of torn fish. An electric knife sharpener ($37.99) resets an edge in under a minute.

The full range is in our professional knife collection, all hand forged and full tang.

2. Fish Scalers, Pin Bone Pliers, and Cutting Boards

Use a commercial metal fish scaler (or the back of a butter knife) to lift scales efficiently. Keep bevel-tipped stainless steel pin bone pliers on hand to extract thin lateral intramuscular bones smoothly. Work on a smooth non-porous board that will not absorb fish oils, such as our two-tone XL cutting board ($29.99) at 18 by 12 inches, which holds a whole 4 lb bass without the tail hanging off the edge.

3. Storage Gear: Vacuum Sealers and Parchment Paper

If freezing fillets, use parchment paper sheets to separate individual fillets before placing them into heavy 4-mil vacuum sealer bags. Finished fumet keeps well in Le Parfait glass preserving jars, which seal as the stock cools.

Step-by-Step Guide: Scaling, Gilling, and Gutting Whole Sea Bass

Proper preparation before filleting ensures clean, scale-free fillets and a tidy workspace.

Step 1: Scaling the Fish Without Making a Mess

  1. Submerge the whole sea bass in a large sink filled with cold water, or place inside a deep plastic tote. Scaling fish under water prevents loose scales from flying across your kitchen.
  2. Grasp the fish firmly by the tail with your non-dominant hand.
  3. Rake your fish scaler firmly against the grain of the scales, moving from tail to head in short, firm strokes.
  4. Pay close attention to scaling thoroughly around the belly, collar, and base of the dorsal fin. Rinse under cold water and feel with your fingers to ensure all scales are removed.

Step 2: Trimming Sharp Fins with Kitchen Shears

Sea bass feature very sharp, rigid dorsal and anal fin spines that can puncture hands easily during processing. Use heavy kitchen shears to snip off the sharp dorsal fin along the top back, the pectoral fins behind the gills, the pelvic fins on the belly, and the anal fin near the tail.

Step 3: Opening the Abdominal Cavity and Removing Viscera

  1. Insert the tip of your filleting knife into the small vent (anal opening) located on the lower belly near the tail.
  2. Slice the belly skin upward toward the throat, keeping the blade tip shallow to avoid puncturing internal digestive organs.
  3. Open the belly cavity with your gloved fingers, reach in near the throat collar, and pull out the internal organs (viscera) in a single backward pulling motion. Discard viscera.

Step 4: Removing Gills and Washing the Blood Line

  1. Lift the hard gill covers (operculum) on both sides of the head. Snip the gill attachments at the top and bottom with kitchen shears and pull out the red feather-like gills completely. (Gills impart bitter flavors to stock.)
  2. Locate the dark red blood line running along the exposed interior spine inside the cavity.
  3. Scrape the blood line with the edge of a spoon or your thumbnail under cold running water until the cavity is clean and white. Pat the fish thoroughly dry with paper towels inside and out.

Step-by-Step Guide: Filleting Whole Sea Bass (Three-Cut Method)

The classic round fish filleting method uses three clean blade passes to release pristine, boneless side fillets.

Step 1: The Diagonal Collar Cut Behind the Gills

  1. Lay the sea bass flat on its side with the head pointing toward your non-dominant hand and the back spine facing away from you.
  2. Lift the pectoral fin behind the head to expose the natural diagonal seam line.
  3. Make a diagonal cut behind the gill cover, angling your blade at a 45-degree angle toward the head until your knife blade touches the hard backbone. Do not cut through the backbone.

Step 2: Tracing the Spine Along the Back Fin

  1. Insert the tip of your flexible filleting knife lightly into the top back skin, starting at the head collar cut and running all the way down to the tail along the base of the dorsal fin.
  2. Make a second, deeper pass along this same line, pressing the flat side of your blade smoothly against the top of the rib cage bones. You will hear and feel a light clicking sound as the knife glides over the rib joints.
  3. Continue cutting inward along the spine until you reach the central backbone column from head to tail.

Step 3: Gliding Over the Rib Cage to Release the Top Fillet

  1. Lift the freed top edge of the fillet with your non-dominant hand to create visibility.
  2. Angle your knife blade slightly downward, following the natural downward arch of the rib cage bones.
  3. Use smooth, long sweeping strokes to slice the fillet away from the curved rib cage toward the belly flap.
  4. Slice through the skin connection at the tail to free the first complete side fillet cleanly. Set aside on a cold tray.

Step 4: Flipping and Removing the Second Fillet

  1. Flip the fish carcass over so the un-filleted side is facing upward.
  2. Make a diagonal collar cut behind the gill on this side.
  3. Insert your knife blade at the tail end this time, tracing along the spine toward the head.
  4. Glide your blade over the top of the rib cage bones in smooth sweeping strokes until the second fillet releases completely from the carcass frame.

Step-by-Step Guide: Trimming, Skinning, and Pin Bone Removal

Once fillets are separated from the frame, fine knife work turns raw fillets into restaurant-ready portions.

Step 1: Trimming Rib Membranes and Fat Belly Flaps

Lay each fillet skin-side down. Slip your filleting knife blade flat underneath any thin rib bones remaining on the belly section, slicing smoothly upward to trim away the thin rib cage membrane and ragged belly fat.

Step 2: Locating and Pulling Pin Bones with Pliers

Sea bass feature a single row of tiny, needle-like intramuscular bones called pin bones running along the centerline from the collar cut to halfway down the fillet. Run your fingertips lightly along the thick center of the fillet from head to tail to locate the buried tips of the pin bones. Grasp each pin bone firmly with stainless steel pin bone pliers and pull gently forward in the natural direction the bone points (toward the head) to extract them cleanly without tearing muscle flesh.

Step 3: The Master Technique for Skinning Fillets Smoothly

If your recipe calls for skinless sea bass, use this classic skinning technique:

  1. Lay the fillet skin-side down on your cutting board with the narrow tail end pointing toward your dominant hand.
  2. Make a small cut through the flesh down to the skin about 1/2 inch from the tail tip, without cutting through the skin itself.
  3. Grasp the loose 1/2-inch skin tab firmly with a paper towel using your non-dominant hand.
  4. Angle your filleting knife blade flat against the skin surface, tilted very slightly downward toward the board.
  5. Pull the skin tab taut with your non-dominant hand while wiggling the skin back and forth against the stationary knife blade. The blade will slide smoothly between flesh and skin, releasing a clean skinless fillet.

Step 4: Portioning Uniform Center-Cut Fillet Portions

Trim uneven, thin edge pieces. Slice thick center fillets crosswise into uniform 6 to 8-ounce portions for even cooking times in the pan.

Step-by-Step Guide: Making Classic French Fish Stock (Fumet)

Classic French fish stock simmering with bones and aromatics

Sea bass skeletons produce delicate, aromatic, collagen-rich white fish stock (fumet) perfect for classic butter sauces, risottos, and chowders.

Step 1: Cleaning Carcass Bones and Removing Gills/Blood

Chop the sea bass head and spine frame into 3 or 4 manageable pieces using a heavy blade. Soak bones in a bowl of ice-cold water for 15 minutes. Scrub away all remaining traces of blood along the spine and ensure all red gills are removed from the head. Blood and gills make fish stock cloudy and bitter.

Step 2: The 20-Minute Simmer Method for Delicate Fumet

Place clean fish bones in a stockpot with 1 tablespoon of butter, sliced white onions, leeks, mushroom stems, and celery (avoid carrots, which discolor white stock). Saute gently for 3 minutes without browning. Add cold water to cover, a splash of dry white wine, a bay leaf, and fresh parsley stems. Bring to a bare simmer over low heat. Simmer gently for strictly 20 to 25 minutes (simmering fish bones past 25 minutes breaks down calcium, making stock bitter and cloudy). Strain through a cheesecloth-lined sieve.

A heavy pot holds a bare simmer without the hot spots that tip a delicate fumet into a boil. See our pots, pans and cookware.

Packaging and Seafood Cold Storage Mastery

Seafood freshness degrades quickly if exposed to warm air, excess surface moisture, or freezer oxidation.

1. Fresh Refrigeration Limits and Ice Bed Storage

Store fresh, raw sea bass fillets inside the refrigerator (34-36F / 1-2C) wrapped gently in parchment paper and placed inside an airtight container set on top of an ice pack. Cook fresh fillets within 1 to 2 days of fabrication.

2. Vacuum Sealing and Freezing Fish Without Crushing Flesh

Delicate fish fillets can be crushed by intense vacuum pressure. To freeze properly, place sea bass fillets on a parchment-lined baking sheet and flash-freeze in the freezer for 45 minutes until firm. Transfer firm frozen fillets into 4-mil vacuum bags and seal tightly. Vacuum-sealed sea bass maintains excellent quality for up to 6 months at 0F (-18C).

Beginner Culinary Guide: Cooking Sea Bass Perfectly

Sea bass features delicate white flakes and moist, rich flesh that pairs naturally with butter, citrus, wine reductions, and fresh herbs.

1. Crispy-Skin Pan-Searing (The Press and Baste Technique)

Score the skin side of a skin-on sea bass fillet with 3 shallow diagonal knife cuts to prevent the fillet from curling during searing. Pat skin thoroughly dry with paper towels and season with kosher salt. Heat a heavy skillet over high heat until smoking, add 1 tablespoon of oil, and lay the fillet skin-side down. Press down firmly on the fillet with a fish spatula for 10 seconds to hold the skin flat against the hot metal. Cook skin-side down for 3 to 4 minutes until the skin is golden brown and crispy. Flip gently, add 1 tablespoon of cold butter, lemon juice, and fresh thyme, and baste the flesh for 1 minute until an instant-read thermometer reads 135-140F. Rest 2 minutes before serving.

The pan does half the work here. A heavy stainless steel frying pan holds its temperature when cold fish hits the surface, which is the exact moment a thin pan drops and the skin steams instead of crisping.

2. Gentle Poaching, En Papillote, and Salt-Crust Baking

For skinless sea bass portions, place fillets inside folded parchment paper pouches (en papillote) with sliced fennel, white wine, butter, and cherry tomatoes. Bake at 375F (190C) for 12 to 14 minutes. Trapped steam cooks the fish gently in its own juices, yielding delicate, moist flakes.

10 Common Beginner Fish Butchering Mistakes to Avoid

  1. Using a Rigid or Dull Knife: Heavy stiff knives hack through delicate flesh. Always use a thin, sharp, flexible filleting knife.
  2. Scaling Dry Fish in the Open Air: Scaling dry fish scatters scales across kitchen walls. Scale under cold water or inside a deep tote bag.
  3. Cutting Through Rib Bones With Force: Hacking through rib bones leaves bone splinters in fillets. Glide your flexible blade gently over the top of the curve.
  4. Leaving Gills in Fish Frames for Stock: Bitter red gills ruin fish fumet. Snip and discard gills completely before simmering stock.
  5. Simmering Fish Stock Too Long: Simmering fish bones past 25 minutes releases bitter compounds and turns stock cloudy. Keep stock simmers short.
  6. Pulling Pin Bones Sideways: Yanking pin bones sideways tears muscle flesh apart. Always pull pin bones forward in the direction they naturally point.
  7. Tearing Flesh During Skinning: Angle your knife flat against the board and wiggle the skin tab, keeping the blade stationary to avoid slicing through skin.
  8. Leaving Blood Lines on the Frame: Dark kidney blood along the spine imparts sour flavors. Scrape and rinse blood lines completely clean.
  9. Cooking Wet Fish Skin: Searing wet skin results in soggy, steamed skin. Pat skin completely dry before adding to hot oil.
  10. Thawing Frozen Fish in Warm Water: Warm water thaws fish unevenly and breeds bacteria. Thaw frozen fillets slowly inside the refrigerator overnight.

Frequently Asked Questions for Beginner Fish Butchers

How long does it take a beginner to fillet a whole sea bass?
A beginner processing their first whole sea bass should expect to spend roughly 10 to 15 minutes scaling, gutting, and filleting. With practice, filleting a round fish takes less than 2 minutes.

Do I need to remove the skin from sea bass fillets?
No. Sea bass skin is delicious, thin, and crisps up beautifully when pan-seared. Skin also protects delicate flesh from drying out during cooking. Skinning is only necessary for poaching or delicate ceviche preparations.

Why is my sea bass fillet curling up in the pan?
Fish skin contracts rapidly when it contacts hot oil. Making 2 or 3 shallow diagonal cuts through the skin with a sharp knife and pressing the fillet flat with a spatula during the first 10 seconds prevents curling.

What size knife do I need for sea bass?
A blade between 6 and 8 inches handles branzino and black sea bass, which are the sizes most markets sell whole. Move up to a longer blade only for striped bass or white sea bass over 4 lbs. Flex matters more than length, because the blade has to follow the rib cage rather than cut through it.

Is branzino the same thing as sea bass?
Branzino is European sea bass, Dicentrarchus labrax. It is one species within a very broad group. The three-cut method on this page works on all of them; what changes is blade pressure, since branzino ribs are far more delicate than a striped bass frame.

Can I cook sea bass whole instead of filleting it?
Yes, and for a 1 to 2 lb branzino it is often the better choice. Scale it, gut it, score the skin, and roast or grill it whole. Cooking on the bone keeps the flesh moist. You still want the gills out, since they turn bitter with heat.

What do I do with the frame and head?
Make fumet. A sea bass frame gives you a delicate white stock in 25 minutes, and it is the base for the butter sauces that suit this fish. Between the fillets and the frame you use close to 80% of the fish.

How long do the fillets keep?
One to two days refrigerated at 34 to 36F. Flash-frozen and vacuum-sealed at 0F, quality holds for about 6 months.

Sea bass needs less equipment than most butchery. These are the pieces that matter.

Free US shipping on orders over $50.

Cook what you just fabricated. Sea bass is a butter-sauce fish. The fumet you made from the frame is the base for veloute, and a crisp-skinned fillet is the classic partner for beurre blanc. The Five Mother Sauces guide explains how each one is built and where fish stock fits.

Next learning step. The three-cut method transfers directly to other round fish. Try snapper next, then whole salmon, which adds pin bone extraction at scale and the collar and belly work. When you are ready for flatfish and its different four-fillet method, go to halibut. For the largest pelagic work, see swordfish.
