What Are Flatfish, Anyway?

Before we dive into the Halibut vs Flounder duel, let’s talk flatfish. Flatfish are, well, flat! They have both eyes on one side of their head, which sounds like a joke Mother Nature played but is actually a brilliant adaptation for life on the ocean floor. Imagine lying on your side all day and still being able to keep an eye on your surroundings!


Halibut: The Heavyweight Champ

Halibut are the Arnold Schwarzeneggers of the flatfish world. These bad boys can weigh up to 500 pounds and span a whopping 9 feet. Their size makes them a favorite among anglers and Instagrammers looking for that perfect “big catch” photo.

They are protected in some areas and have to be a minimum size before you can catch them.

Culinary Profile

When it comes to taste, halibut is like the Rolls Royce of flatfish. It has a sweet, delicate flavor and a firm texture that holds up well to grilling, frying, and baking. The meat is white and flaky, almost begging to be seasoned and savored. Have you ever tried a delicious halibut steak with lemon-butter sauce? If not, let me tell you, you’re missing out on a life-altering experience.

Fishing for Halibut: How to Reel in the Big One 

  1. Deep Waters: Halibut love the deep, so aim for waters that are at least 100 to 400 feet deep.

  2. Heavy Gear: Due to their massive size, halibut require strong, heavy-duty fishing gear. We’re talking high-capacity reels, strong fishing lines, and large, sharp hooks.

  3. Bait: Halibut aren’t picky eaters. Salmon heads, octopus, and large jigs can all make effective bait.

  4. Timing: Early morning or late afternoon are often cited as the best times to fish for halibut.

  5. Technique: Drop your line to the bottom and then reel it up a few feet to ensure your bait is visible. Periodic jigging can attract attention.

  6. Safety: Halibut are strong and can weigh hundreds of pounds. Always use caution when reeling one in and consider using a harpoon to secure your catch.

Fishing for Flounder: Mastering the Art of Subtlety

  1. Shallow Waters: Unlike halibut, flounder are found in shallower waters, often between 10 and 50 feet deep.

  2. Light Gear: Light to medium tackle is usually sufficient for flounder. Look for gear specifically designed for flatfish.

  3. Bait: Live bait like shrimp or minnows tend to work best, although artificial lures can also be effective.

  4. Timing: Flounder can be caught throughout the day, but many anglers swear by the hours surrounding the changing tides.

  5. Technique: Cast your bait and let it sink to the bottom. Slow, steady retrieves work well. Some anglers like to use a “tap and pause” technique to mimic natural prey.

  6. Patience: Flounder bites can be subtle, almost like a gentle tug. Be patient and wait for the fish to fully take the bait before setting the hook.
