How to Really Fish Island Progression: The Ultimate Guide to Unlocking Every Island

Surviving a shipwreck is only the beginning of your journey in the hit indie title How to Really Fish. To truly master the game, you must understand how to really fish island progression to unlock new waters, rare species, and powerful gear. If you are feeling stuck on the starting shores, this guide will walk you through every step of how to really fish island progression, ensuring you have the right bait and weapons to conquer every boss from the Spider Crab to the Mutated Bowhead Whale.

The Foundation: Island 1 and the Spider Crab

Every player begins their journey shipwrecked on a desolate island featuring a solitary lighthouse and a mysterious man on a bench. This initial area serves as a tutorial, but it quickly ramps up in difficulty. To move forward, you must secure the Boat Keys, which are held by the NPC on the bench. He won't hand them over for free; you need to rid the island of a "long-legged creature" known as the Spider Crab.

Before you can even think about fighting a boss, you need to establish a financial base. Start by catching basic fish to earn enough for a Knife ($45) and a Beer Can ($12). Community reports suggest that attempting the boss without at least two knife upgrades is a recipe for disaster. Visit the Anvil and spend the $12 and $28 required for these upgrades to ensure your melee damage is sufficient.

When you are fully prepared, give the man the Beer Can. He will return an empty can, which serves as your specialized bait. Cast your line, hook the Spider Crab, and get ready for a fight. Unlike standard catches, bosses have health bars. Wait for the crab to enter a brief stun state before rushing in for attacks, then retreat to avoid its counter-strikes. Once defeated, the man will grant you the keys to the boat.

Navigating the Depths: Island 2 and the Giant Piranha

Once you leave the first island, the world of How to Really Fish opens up. However, navigating is impossible without a Radar, which can be purchased for $10 near the man on the bench. When you board your boat, the Radar will display a dark green blip. If you are playing solo, you will need to stop the boat periodically to check your heading, as you cannot steer and hold the Radar simultaneously.

Upon reaching the second island—identifiable by its lush tree line—you will meet a woman who needs help preparing a meal for her father. Her request involves catching a Giant Piranha. This is where the game introduces firearms. You will find a shop board in the center of the island offering a Pistol and a Shotgun ($150). We highly recommend saving up for the Shotgun and maxing out its upgrades at the ammunition crates before engaging the boss.

To lure the Giant Piranha, you must scour the island for three leeches. Hand these to the woman to receive the Leech Bait. During the boss fight, smaller piranhas will spawn frequently. Player experience suggests that these minions are actually a blessing in disguise; killing and selling them is the fastest way to grind for the Big Motor ($230), which significantly speeds up travel between islands.

Tropical Tactics: Island 3 and the Pufferfish

The third island is marked by swaying palm trees and an orange dot on your Radar. Here, you will encounter a stranded tourist wearing a life vest. This NPC wants to prove their "vacation" was a success by catching a legendary fish. To help them, you must first catch an "endangered fish" to trade for Carrot Bait.

The game is somewhat vague about which fish qualifies as endangered, but community members have confirmed that a Needlefish, Seahorse, or Bowlfish will satisfy the requirement. Once you trade your catch for the Carrot Bait, do not rush into the fight. The Pufferfish boss is notoriously difficult due to its high health and explosive attacks.

The best strategy for how to really fish island progression at this stage involves heavy ordnance. Purchase the Uzi and upgrade it fully, but the real secret weapon is Dynamite. By placing a stack of Dynamite in the center of the island and detonating it as the Pufferfish approaches, you can shave off a massive portion of its health bar instantly. After the victory, give a piece of the Pufferfish to the tourist to receive the coordinates for the fourth island.

The Urban Grind: Island 4 and the Albatross

Island 4 stands out with its tall buildings and cityscape silhouette. This island represents a significant difficulty spike and requires a disciplined approach to your finances. Your ultimate goal here is to purchase the Professional Boss Lure for $1,200, but you will also need the Sniper Rifle, which costs a staggering $3,800.

To make money efficiently, you should buy the Professional Lure ($50) early on. A vital tip from veteran players is to always grill and cook your fish before selling them to the vendor. This simple step significantly increases the payout for every catch. Once you have the Sniper Rifle and its associated bullet upgrades, you are ready for the two-stage boss encounter.

First, you must use the Professional Boss Lure to catch a Tuna. After defeating the Tuna, you use its body as bait for the Albatross, a massive bird that circles the island. The Albatross will swoop down to attack and fire projectiles from the air. The Sniper Rifle is mandatory here, as it allows you to deal damage while taking cover inside the vendor shed. Defeating the Albatross yields its head, which you can trade for the pink Radar coordinates leading to the final island.

The Final Peak: Island 5 and the Mutated Bowhead Whale

The final destination in the current how to really fish island progression is the Volcano Island, indicated by a pink dot. Here, a scientific team is conducting research and requires your assistance. The head scientist will ask you to catch and deliver five fish of any species. While this sounds simple, use this time to visit the military merchant and purchase the Assault Rifle, the most powerful weapon in the game.

After delivering the fish, you will receive the Fish Bucket bait. This summons the Bowhead Whale, a massive creature that attempts to crush the player by slamming its body onto the small island. Once the whale is defeated, the quest isn't over. You must haul the whale's carcass to the top of the volcano and throw it into the lava.

This action triggers the final boss: the Mutated Bowhead Whale. This fight tests everything you have learned about positioning and weapon management. According to official game guides and community wikis, maximizing your damage threshold at the military merchant is the only way to survive the mutated whale's increased aggression. Defeating this final form earns you the keys to return to the mainland and completes your primary progression.

Advanced Tips for Smooth Progression

Understanding the mechanics of how to really fish island progression is about more than just knowing where to go. It is about resource management. Always keep an eye on your Radar; if you lose it, you can rebuy it at most island shops for $10. Furthermore, don't ignore the casino tables found on the later islands. While risky, they can be a shortcut to the expensive Sniper Rifle or Assault Rifle if luck is on your side.

Another key aspect of how to really fish island progression is understanding bait mechanics. Each island has a specific "loop":

1. Talk to the primary NPC.
2. Complete a sub-quest or gather materials (leeches, endangered fish).
3. Trade for the boss bait.
4. Upgrade weapons to the island's cap.
5. Defeat the boss and turn in the trophy for coordinates.

If you ever find yourself unable to damage a boss, check the local anvil or ammo crate. The game is designed so that each island's weapons are barely sufficient at base level, making upgrades a requirement rather than a luxury.

Conclusion

By following the questlines of the stranded NPCs and ensuring your gear is always maxed out for your current region, you can navigate the treacherous waters from the first lighthouse to the final volcano. Remember to always check your radar, keep your shotgun loaded, and never underestimate the power of a well-placed stick of dynamite.
