How to Catch the Best Fish and Master the River with Shin Chan

While catching bugs is great for making headlines in the local newspaper, fishing in Shin Chan: Me and the Professor on Summer Vacation is the true economic engine of your adventure. A good fishing session is an exercise in zen and patience that not only fills Shinnosuke’s Summer Diary but also provides the fastest and most consistent way to earn Yen for snacks and dinosaur cards.

Grab your fishing rod and head to the water. Here is your comprehensive guide to reading the rivers and catching the best fish in Asso.

The Mechanics: The Art of Patience

The fishing system in the game is incredibly simple, but many beginners fail because they get too anxious.

• Aim for the Shadow: When casting your line, aim to drop the bobber near the fish's silhouette, but not directly on top of it, which can sometimes scare them or cause awkward pathing.
• Do Not Pull on the First Nibble: This is the golden rule of fishing. The fish will investigate your bait and nibble it a few times, causing the bobber to dip slightly. Ignore this. You must wait for the "strong pull"—the moment the bobber gets completely dragged underwater accompanied by a loud, distinct splashing sound. Only then should you press the button to reel it in.

Reading the Water: Shadows and Sizes

Efficiency in fishing comes from knowing what you are going to catch before you even cast your line. Do not fish blindly.

• Silhouette Sizes: The game tells you what tier of fish you are targeting via the shadow in the water. Small, round shadows will yield common catches like Minnows or Frogs. Long, slender shadows might be an Eel, while massive, thick shadows are usually large Carp or Salmon. If you are hunting for rare fish, ignore the tiny shadows entirely to save time.
• The Respawn Trick: If you arrive at a riverbank and only see tiny shadows, do not waste your time clearing them out. Simply walk off the edge of the screen and immediately walk back in. This completely refreshes the spawn pool, giving you a new chance to spot a large, rare shadow.

Fishing Zones: Know Your Rivers

Different species inhabit different biomes across the map. You will need to travel to specific spots to complete your encyclopedia.

• The Town Stream: Located right near the Nohara family's vegetable garden and the Kurokami Restaurant. This shallow water is ideal for beginners and yields Crayfish, Frogs, and common small river fish.
• The Wide River Under the Bridge: As you venture further out, you will find the larger river section. This is the perfect intermediate zone for catching good-sized Carp and the highly requested Ayu fish.
• Hidden Ponds and the Waterfall: These areas are locked early on and will become available as you complete the Professor's dinosaur missions. The deep forest waters and waterfall basin are home to the absolute rarest and most valuable species in the game.

The Aquatic Elite: The Most Wanted Fish

If you are a completionist looking to catch the absolute best the game has to offer, keep your eyes peeled for these prestigious targets:

• The Japanese Eel: Identifiable by its distinct, snake-like shadow in the water. Eels tend to spawn in slightly deeper waters and are highly valuable.
• Salmon and Large Trout: The kings of the upstream currents. You will need access to the deep forest and waterfall areas to find these massive fish. They provide fantastic newspaper articles and sell for top dollar.

The Reward: Kurokami Restaurant

So, what do you do with a pocket full of fish? You become the town's best supplier.

• The Bulletin Board: Never fish purely at random if you are low on money. Always start your morning by checking the bulletin board at the back door of the Kurokami Restaurant. Yoshiko will post specific daily requests for certain types of fish (like three Ayu fish or two Crayfish).
• Massive Payouts: Fulfilling these specific bounties pays significantly more Yen than simply selling items randomly. Catching the exact fish the restaurant needs is the ultimate strategy for getting rich quickly and ensuring Shin Chan can afford all the Chocobi and dinosaur upgrade cards he desires.
