NPC quests drive almost all meaningful progression in Fish It. Plain fishing earns coins and experience, but the quests are what hand you stronger rods, luck potions, enchant stones, and access to hidden areas. Some take a few minutes; others demand rare fish, mutations, and thousands of catches before you can turn them in.
Quick answer: Start with the Scientist’s Test Subjects quest on Fisherman Island for a Luck II Potion, stack luck early, then save the Diamond Researchers and Crystalline Secrets quests for when your gear can handle them.

Fisherman Island quests
Test Subjects (Scientist)
The Scientist on Fisherman Island wants three specific fish for his experiments. Catch one Darwin Clownfish in coral reef areas, one Dogfish from deeper ocean water, and one Barracuda Fish from tropical waters. Hand them in for a Luck II Potion, which raises your chance of catching rare fish. This is the best early quest to clear first because the luck boost makes every later hunt easier.
Diamond Researchers (Lary)
Lary’s quest is the hardest standard task in the game and rewards the Diamond Rod, currently the strongest rod available. You need to own an Element Rod, catch a Secret Fish at both Coral Reefs and Tropical Grove, bring a mutated Gemstone Ruby and a Lochness Monster, and catch 1,000 fish with perfect throws. Treat it as a true endgame goal rather than something to rush.
Kohana Volcano and lab quests
Kohana Explorer (Lava Fisherman)
The Lava Fisherman asks you to catch volcanic fish near the lava edges without falling in. Lava kills you instantly, so fish from safe footing and reposition carefully. Completing it gives the Lava Rod, which is built for hot volcanic water.
Spicy Fish (Volcanic Fisherman)
The Volcanic Fisherman needs 20 Lava Butterfly, 5 Magma Goby, and 1 Lavafin Tuna. These appear only in volcanic areas, so the Lava Rod from the previous quest makes the grind faster. Your reward is a Luck I Potion.
Swimming Narwhals (Narwhal)
The Narwhal NPC wants you to catch 150 fish of any type and fish up 1 Narwhal. Narwhals are a rare spawn in deeper water, so luck potions help. Completing it gives an Enchant Stone, used to add effects to your rod.
A Rumor (Phil and Bill)
Phil and Bill only want you to catch a few fish from the laboratory area, then report back. It pays out 5,000 coins and is one of the fastest quests in Kohana.
Sample Collection (Scientist Jameson)
Scientist Jameson sends you to collect 10 sample flags spread around Kohana Volcano. Turning them in gives a Luck Potion and opens the next part of the science questline. Afterward, speak to Scientist Lucille.
The Forgotten Tool (Scientist Lucille)
Inside the Kohana Lab, Scientist Lucille hands you the Measurement Device and asks you to deliver it to Crater Island. This is a connector quest that unlocks the next step, so don’t skip it.
Taking Measurements (Scientist Samantha)
On Crater Island, equip the Measurement Device and scan 15 spots by clicking with the tool in hand as you move around the island. The reward is a Mutation Potion, and it unlocks fishing at the Kohana laboratory area.
Ancient Jungle quests
Mushroom Collector (Forager Jen)
Forager Jen needs 30 glowing mushrooms gathered around the Ancient Jungle. They grow near trees and rocks and glow faintly, which makes them easier to find at night. The reward is the Mushroom Lantern, which improves visibility in dark areas and underwater.
Variety Diet (Forager Jen)
Jen’s second quest asks for 12 mutated fish. Any mutation counts, so keep fishing until you reach 12. You earn a Mutation I Potion, which raises your odds of catching mutated fish later. Pairing luck and mutation potions speeds this up.
Coral Reefs and Tropical Grove quests
Prove Thyself (Sam)
Sam wants 3 Epic rarity fish and 1 Pink Dolphin. Epic fish are uncommon, and Pink Dolphins are rarer still, usually in deeper water. It takes patience, but the payout is 25,000 coins.
We’ll Show Him (Ram)
Ram competes with Sam and asks you to catch 8 big fish. It pays a Luck I Potion and pairs well with Sam’s quest since you are already fishing the same area.
Lost Treasure (Captain Jack)
Captain Jack at Tropical Grove wants you to loot 5 treasure chests. Chests spawn randomly on beaches and underwater near rocks and coral, and they glow. The 40,000 coin reward is the largest single cash payout among these quests.
Esoteric Depths quest
Enchanting Discoveries (Esoteric Gatekeeper)
The Esoteric Gatekeeper asks you to use enchant stones 30 times. You can re-enchant the same rod repeatedly to count uses, so you don’t need 30 separate rods. The reward is a Super Enchant Stone, a stronger upgrade that grants better enchantments.
Pirate Cove quests
TNT (Carpenter)
The Carpenter needs four TNT sticks to clear rubble blocking a cave. One sits next to the Fish Monger NPC, one near the docks among the wooden structures, one inside a small cave on the island, and one near the main pathway. Collect all four, return, and place them. The explosion opens a diving area that leads into deeper content.
Black Pearl (Captain Jones)
Captain Jones stands on the docks and wants a fish carrying the Leviathan’s Rage mutation plus the Dead Man’s Compass. Both take time and luck. The Leviathan’s Rage mutation is tied to admin boost events, where a giant Leviathan appears and grants a large luck boost, so those windows are your best shot.
Deadman’s Treasure (Dead Skeleton)
In the maze beneath Pirate Cove, the Dead Skeleton asks for four letters hidden inside Pirate Cove chests. Chests spawn randomly and drop the letters in four parts. One chest near the starting area respawns roughly every 10 minutes, so you can camp it and reopen it. Turning in all four letters grants treasure room access or the Dead Man’s Compass needed for Captain Jones.
Crystal Depth quests
Crystal Gathering (Hank)
Hank lives inside Crystal Depth and rewards a pickaxe. To reach him, buy the Advanced Diving Gear for 1 million gold from the back of the Pirate Cove dock, which lets you dive up to 200 meters, then descend through the special diving spot. Fish the nearby pond until you catch the mysterious diary. Equip the diary in your hand before talking to Hank again, since turning it in requires holding it. He then gives you the pickaxe to mine glowing crystals.
Coral (Dorian)
Dorian’s optional quest asks for 30 coral collected across the underwater area. Coral spawns under the entry dock, near the diary fishing pond, and inside the cave, and it respawns so you can gather several per dive. Hand in all 30 for the Coral Lantern Skin, a cosmetic that changes your lantern’s look.
Secret and endgame quests
Forgotten Scale (Archeologist)
Talk to the Archeologist before starting the daily Leviathan Hunt to begin the Forgotten Scale quest. It requires three relics from Crater Island, Tropical Grove, and Lost Isle, plus the Leviathan Scale. On-screen arrows point to each relic, but other players may race you, so teaming up and splitting islands helps. Once everything is turned in, the Leviathan’s Den opens automatically, and only one player per server needs to finish it for everyone to enter.
Crystalline Secrets (Ghastly Pirate)
The Ghastly Pirate on Crater Island sets the hardest quest in Fish It. You must own an Element Rod and a Singularity Bait, catch a Cursed Kraken, catch an Elpirate Gran Maja, and catch a Mythic fish with the Crystalized mutation. Clearing it rewards the Aetherion Bait, the strongest bobber currently in the game. It is meant for fully geared players only.
Work through these in dependency order rather than all at once. Clear the easy luck and coin quests first to build up potions and currency, push the science chain in Kohana to unlock the laboratory area, then tackle the Diamond Researchers and Crystalline Secrets quests once your rod, baits, and luck stacks can actually carry the rare requirements. Following that order turns Fish It from a grind into steady, predictable progress.
