You’re standing on the pier. It’s raining. Your pockets are full of Manila clams, and your thumb is hovering over the A button, twitching. We’ve all been there, staring at that massive shadow in the water, praying it’s a Blue Marlin and not another sea bass. Honestly, the Animal Crossing New Horizons fishing guide experience is half relaxation and half high-stakes gambling.
Fishing isn't just about hitting a button when the bobber dips. It’s about understanding the rhythm of the seasons, the specific quirks of the Northern and Southern hemispheres, and knowing exactly when to give up on a specific shadow size. Most players just run along the beach scaring everything away. Don't do that.
Why Your Animal Crossing New Horizons Fishing Guide Strategy is Probably Failing
Most people think fishing is random. It’s not. The game uses a weighted spawn system based on your location, the time of day, and the current weather. If you’re looking for a Coelacanth on a sunny day, you’re literally wasting your time. It only spawns when it’s raining. Period.
Shadow sizes are the first thing you need to memorize. There are six standard sizes, plus the "long" shadows with fins. If you see a size 6 shadow—the absolute unit of fish shadows—in the ocean, you’re looking at a Whale Shark, an Oarfish, or the dreaded Sea Bass. If you’re at the mouth of the river where it meets the sea, that same shadow could be a King Salmon or a Sturgeon.
Context is everything.
The Secret of the River Mouth and Clifftops
Specific fish are locked to tiny geographical zones. The Sturgeon only hangs out at the river mouth. The Golden Trout? Only at the highest point of your island, in the clifftop ponds or rivers. If you aren’t using your ladder or your terraforming skills to reach those high-altitude spots, you are missing out on the rarest (and most expensive) catches in the game.
I’ve spent hours throwing bait into the "mouth" of the river. That’s the transition zone where the river water meets the ocean sand. It’s a goldmine. You can force spawns there by running away and coming back, or better yet, using fish bait.

How to Actually Catch the Rare Stuff
Fish bait is the great equalizer. You dig up Manila clams on the beach—look for the little water squirts in the sand—and craft them at a workbench. One clam equals one bait. It’s tedious. It’s boring. But it’s the only way to target specific rare spawns without waiting for RNG to be kind.
Here is the thing about bait: it resets the spawn immediately. If you’re on the pier trying to get a Tuna or a Giant Trevally, don't wait for shadows to appear naturally. Stand at the very end of the wooden planks, throw bait, and check the shadow. If it’s not a size 5 or 6, ignore it or scare it away by running. Throw bait again. Repeat until you see the "Big One."
Sound vs. Sight
This is a pro tip that sounds weird until you try it: Close your eyes.
When a fish nibbles, it can poke the bobber up to four times. On the fifth time, it must bite. However, it usually bites on the second or third. If you watch the screen, your eyes will often trick you into reacting to a nibble. If you listen for the "plop" sound, your ears are much faster. The sound of a bite is distinct and heavy. Close your eyes, listen for the splash, and hit A. You’ll catch way more rare fish this way, especially the ones with short bite windows like the Great White Shark.
The Seasonal Grind
The Animal Crossing New Horizons fishing guide shifts every single month. In the Northern Hemisphere, December brings the Stringfish, one of the hardest fish to catch. It only appears from 4 PM to 9 AM in the clifftop rivers. If you miss that window, you’re waiting months for it to return.
The game operates on real-time. If you’re a time traveler, you can skip around to find what you need, but for the purists, you have to respect the calendar. Summer months (June–September in the North) are the "Shark Season." Look for shadows with a little fin sticking out of the water. These are almost always high-value catches, ranging from the Saw Shark to the Hammerhead.

Breaking Down the High-Value Targets
Some fish are just worth more than others. If you’re trying to pay off your home loan to Tom Nook, stop catching Crucian Carp. Focus on these:
- Barreleye: Found in the ocean at night (9 PM – 4 AM). It has a tiny shadow, which makes most people ignore it. Don't. It’s worth 15,000 Bells.
- Mahi-mahi: Found only at the pier. It’s a size 5 shadow. It’s notoriously difficult to spawn.
- Stringfish: Clifftop rivers, 15,000 Bells. It’s the "boss" of the river.
- Arapaima: Found in the river during the evening in summer. It’s huge and looks like a log.
If you have C.J. visiting your island, save these high-value fish. He buys them for 1.5x the standard price at Nook’s Cranny. A 15,000 Bell fish suddenly becomes 22,500 Bells. That’s a massive jump when you have a stack of them.
Handling the Weather and Pier Mechanics
Rain is your best friend. In the ocean, rain increases the spawn rate of rare fish, most notably the Coelacanth, which is available year-round but only when it’s raining. If you see clouds, get your rod ready.
The pier is a unique biome. There’s only one on your island (the wooden structure sticking out into the ocean). You cannot find the Blue Marlin, Tuna, Mahi-mahi, or Giant Trevally anywhere else. Most players forget the pier exists for fishing. I usually craft about 30-50 bags of bait before heading to the pier. Throwing bait off the side of the pier is the most efficient way to complete your Critterpedia.
The Mystery Island Hack
If you’re struggling to find rare fish on your home island, buy a Nook Miles Ticket. Some mystery islands are "Big Fish Islands" where only size 4 shadows or larger spawn. Others are "Shark Islands." If you land on one of these, stay there until your pockets are overflowing. Even if you have to dump your tools to make room, do it. A shark is worth way more than a stone axe.
Avoid These Common Mistakes
Stop running near the water. Seriously. If you’re sprinting, you’re scaring away shadows before you even see what they are. Walk. Tilt the joystick gently.

Also, don't forget to check the ponds. Ponds are the small, landlocked bodies of water that don't flow into rivers. They have their own set of fish, like the Gar or the Pop-eyed Goldfish. Many people mistake ponds for rivers or vice versa. If the water isn't moving, it’s a pond. If you’re not sure, throw a piece of bait in; if the water doesn't carry the bobber in a direction, it’s a pond.
Equipment Matters
While a flimsy rod works, it breaks after about 10 catches. The standard fishing rod lasts for 30. The colorful, outdoorsy, or fish rods you buy from the cabinet at Nook’s Cranny have the same durability as the standard rod—they just look cooler. There is a Golden Rod, but you only get the recipe after catching every single fish in the game. It lasts longer (90 catches), but by the time you get it, you’ve basically finished your journey.
Actionable Next Steps for Your Island
To maximize your efficiency right now, go dig up 20 Manila clams. Craft them into bait. Wait until after 4 PM when the more expensive fish start to emerge. Head to your clifftop river and start casting.
Focus on the "shadow size to location" ratio. If you are in the river and see a tiny shadow, it's likely a Bitterling or a Pale Chub—hardly worth the effort. If you see a medium-large shadow in the river, it could be a Black Bass (the "metal" of all fish, as the game jokes) or something better like a Dorado depending on the season.
Keep a storage shed or a few fish tanks near your pier. When you catch something valuable but C.J. isn't on your island, don't sell it to the twins at Nook's Cranny. Place the fish on the ground or store them. Waiting for C.J. to show up can turn a 100,000 Bell haul into 150,000 Bells with zero extra effort.
Check your Critterpedia. It tells you the months and times a fish is active once you've caught it once. For the ones you haven't caught, use an online tracker or a companion app to see what’s leaving at the end of the current month. Prioritize those "leaving soon" fish first so you don't have to wait an entire year for the cycle to reset.
Move your fishing spot every 10-15 minutes if you aren't using bait. The game’s spawn rates can feel stagnant if you stay in one acre of the map for too long. Walking around the entire perimeter of your island refreshes the spawns and gives you a better chance at seeing a variety of shadow sizes. Take your time, listen for the splash, and keep your pockets clear for the big ones.
