List of 100 Different Types of Fish

If you’re anything like me, one of the best parts of fishing is discovering the sheer variety of fish out there. Knowing the different types of fish can make your fishing trips even more exciting. From freshwater favorites to deep-sea giants, this bio diversity is fascinating.

When it comes to enjoying a delicious meal, few things rival the taste of fresh fish. Whether grilled, baked, or fried, the right fish can elevate any dining experience. But with so many options available, you might wonder which types are the best to eat.

From the flaky and mild white fish like cod and halibut to the rich and flavorful salmon, there's a perfect fish for every palate. Not only are these fish tasty, but they also offer a wealth of nutritional benefits, making them a healthy choice for any meal. Let's dive into some of the best fish to eat and explore their unique flavors and culinary possibilities!

Common Types of Freshwater Fish

Freshwater fish are the kind you’ll find in rivers, lakes, and ponds. These guys are pretty common, especially in North America. Some of the most recognizable species include the largemouth bass, trout, and catfish. I remember the first time I caught a largemouth bass; it was so big I thought I’d need a bigger boat!

According to the U.S. Fish and Wildlife Service, about 40% of all fish species are freshwater fish, and there are more than 10,000 species of freshwater fish worldwide! That’s a lot of fish to keep track of, right? But don’t sweat it. The best way to get to know them is by paying attention to their specific body features, colors, and habitats.

Many freshwater fish have a rounder body compared to saltwater fish, and their scales tend to be smaller. Their colors are often more muted—think browns, greens, and subtle blues. Have you ever noticed that the clearer the water, the more vibrant the fish? I swear, it’s like they’re showing off.

What are Popular Freshwater Fish for Fishing?

If you’re angling to catch some tasty freshwater fish, you’re in luck. I personally love catching walleye, bass, trout and catfish. They’re not only fun to reel in, but they also make for a pretty tasty dinner.

Fun fact: the rainbow trout is one of the most sought-after freshwater fish. They’re super colorful with bright pink and silver hues, and they put up a great fight on the line.

And don’t get me started on catfish. These slippery, bottom-dwelling creatures are almost like the ninjas of the fish world. They’ve got whiskers, and they love hiding in the mud. Plus, if you’ve never tried fried catfish, trust me—you’re missing out.

Varieties of Saltwater Fish

Moving on from lakes and rivers, let’s talk saltwater fish. If you’re lucky enough to fish off a coast or in the ocean, you’ve probably encountered some pretty wild fish species. My all-time favorite is the red snapper. Not only do they look cool with their fiery red color, but they also taste amazing grilled with a bit of lemon out of the sea.

Some other notable saltwater fish include tuna, marlin, and mackerel. Marlin are especially impressive to catch because they’re so massive. I mean, have you seen those pictures of anglers standing next to one of these fish? It’s like trying to hold a small whale!

Which Saltwater Fish is Favorite for Sport Fishing?

For sport fishing, you can’t beat swordfish and tuna. These fish are the heavy hitters in the ocean, and they’re known for their speed and strength. Swordfish can weigh up to 1,400 pounds, and believe me, you’ll know when you’ve hooked one. It’s like a workout and a fishing trip all in one.

Interestingly, according to the National Oceanic and Atmospheric Administration (NOAA), recreational saltwater fishing contributed $72 billion to the U.S. economy in 2018. If that doesn't make you want to grab your rod and head to the coast, I don’t know what will.

Colorful Species of Tropical Fish

If you’re a fan of aquariums or ever gone snorkeling in a coral reef, you’ve seen the incredible diversity of tropical fish. These fish are like the rainbow of the ocean, with colors that will blow your mind. I once swam with clownfish, and yes, they do remind you of "Finding Nemo." These little guys love darting in and out of sea anemones, and they’re just as playful as they look.

Another dazzling species is the angelfish. Their unique shape and bright colors make them one of the most recognized fish among tropical waters. These fish thrive in warm, clear water, making tropical islands the ideal spot to find them. Ever thought of taking a vacation and fishing in tropical waters? Now’s the perfect excuse!

What are the Top Tropical Fish for Your Aquarium?

If you’re not heading out to the tropics anytime soon, no worries. You can bring the tropical fish world into your home with an aquarium. The betta fish and guppy are two of the easiest tropical fish to care for at home. Plus, they’re colorful, easy to find at pet stores, and fun to watch swim around.

I’ve had my share of aquarium disasters, though. One time, I accidentally overfed my fish and ended up with cloudy water and some very unhappy swimmers. But after a little trial and error, I figured it out, and now my betta fish, Blue, is living his best life.

Discover the Mystery of Deep-Sea Fish

Deep-sea fish are the stuff of legends. These guys live way down where the sun doesn’t shine—literally! If you’ve ever seen an anglerfish, with that creepy glowing lure, you know what I’m talking about. These fish have adapted to extreme conditions, and they’re fascinating to learn about, even if we won’t be catching them anytime soon.

The deepest parts of the ocean are still largely unexplored, but scientists estimate that there are more than 2,000 species of deep-sea fish. And get this, some can withstand pressures over 1,000 times what we experience at sea level. Talk about tough fish!

Unique Adaptations of Deep-Sea Fish

One of the wildest things about deep-sea fish is how they’ve adapted to their dark, cold environment. The anglerfish uses bioluminescence to lure its prey, while the gulper eel can expand its mouth like a pelican to swallow prey whole. These fish are truly creatures of the deep, and their biology is mind-blowing.

Some of them even have transparent bodies, like the barreleye fish, whose head is literally see-through. Can you imagine catching one of these guys? I’m not sure if I’d be amazed or freaked out.

How to Identify a Fish in 5 Steps?

Now, let’s talk about how you can identify different types of fish without Googling every catch. Here’s a quick and easy method that works for me every time:

• Check the shape: Fish have distinct body shapes. Tuna, for instance, are sleek and built for speed, while a catfish is more bottom-heavy and flat.
• Look at the fins: Different fish have different fin shapes and placements. Some, like sharks, have a distinct dorsal fin.
• Examine the color: Many fish species have tell-tale color patterns. For example, a clownfish has those iconic orange and white stripes.
• Size matters: If you’re unsure, checking the fish’s size can help narrow things down. Is it tiny like a guppy, or hefty like a marlin?
• Habitat clues: The location where you caught the fish often gives away the species. Freshwater fish won’t be hanging out in the ocean, after all!

Next time you reel in a catch and wonder what species it is, try running through these steps. It’s like playing detective—but with a fishing rod!

FAQs About Fishes

Here are the answers to some of the most asked questions regarding all types of fish:

What’s the largest fish ever caught?

The largest fish ever caught was a great white shark off the coast of Australia in 1959. It weighed over 2,600 pounds! That’s roughly the size of a small car.

While reeling in one of these might be rare, it just goes to show that the ocean holds some pretty massive creatures.

What’s the best bait for catching trout?

In my experience, trout fish likes to eat worms, but power bait is also a great option. If you’re feeling adventurous, try using insects or minnows. Each type of trout might prefer a different bait, so don’t be afraid to mix it up and see what works best in your area.

How many types of fish are there globally?

There are about 33,000 recognized species of fish globally. That’s a pretty mind-blowing number, considering how many species remain undiscovered, especially in deep-sea environments. From the tiny guppy to the massive whale shark, the diversity is incredible.

Are there any endangered fish species?

Unfortunately, yes. Some fish species, like the bluefin tuna and certain types of sturgeon, are critically endangered due to overfishing and habitat loss. If you’re fishing, it’s important to follow local guidelines to help preserve these species for future generations.
