The Fish It deep ocean sits near the top of the island progression ladder, and reaching it changes what your rod can actually pull in. Players who clear the level gate land in a biome packed with high-value pelagics, tougher catch windows, and some of the cleanest coin-per-hour returns anywhere outside the limited-time events. This guide walks through the level requirement, the hotspots that pay off inside the deep ocean, and the rare catches that justify the grind — including how the zone compares with neighboring islands like the volcano island and the broader list of Fish It island locations.
Level Requirement and How to Reach the Deep Ocean
Unlocking the deep ocean is a hard prerequisite before any of its hotspots matter. The zone is gated behind both an account level and a craftable item, which is why newer players tend to bounce off the boundary even after they have the rods for it.
Account Level and Crafted Key
The official requirement to enter the deep ocean is Player Level 75 plus a single Trident crafted at the workbench on Coral Island. The Trident is not a weapon — it functions as the access key that opens the whirlpool transition near the right side of the Coral harbor. Community testing across multiple servers confirms the level check is enforced server-side, so XP boosts from potions or codes stack but cannot shortcut the level floor itself.
| Requirement | Value | Source / Notes |
|---|---|---|
| Account Level | 75 | Hard gate, enforced server-side |
| Crafted Item | Trident | Made at the Coral Island workbench |
| Craft Cost | 5,000 Coins + 5 Coral Shards | Shards drop on Coral Island |
| Recommended Rod | Rod of the Depths or better | See Fish It rod progression |
| Recommended Bait | Magnetic Lure / Colossal Bait | Greatly improves rare catch rate |
Players who hit the level but skip the Trident cannot enter the whirlpool, which is a common stumbling block in the early endgame. The shards themselves are farmable on Coral Island while leveling, so by the time the level gate opens, most of the crafting material is already banked.
Fastest Route From Starter Cove
A clean route from Starter Cove to the deep ocean looks like a four-stop pipeline rather than a single jump. Follow the island progression guide for a wider view, but the core path runs: Each stop along that pipeline unlocks a slightly higher-tier fishing spot with better coin-per-hour averages.
-
Starter Cove (Level 1) — push the main questline until the Sandy Shores fast-travel pier activates.
-
Sandy Shores (Level 10) — farm Pufferfish and Trevally for coin and XP; avoid spending on cosmetics here.
-
Coral Island (Level 30) — unlock the workbench, start farming Coral Shards, and stockpile 5,000 Coins for the Trident craft.
-
Deep Ocean (Level 75) — craft the Trident, equip a Depths-tier rod, and dock at the whirlpool transition.
Most players reach the gate in roughly 6 to 10 hours of focused play, depending on whether they redeem active codes for XP potions. A breakdown of all active codes confirms that luck and XP boosts rotate frequently, so checking before a level push is a small but consistent time save.
Best Fishing Hotspots Inside the Deep Ocean
Once the gate opens, the deep ocean is not a single uniform water tile. It splits into three distinguishable hotspot zones, each tuned around a different weight class of fish and a different rhythm of cast timing. Knowing which zone to sit in for your current target is the single biggest driver of coin-per-hour.
The Trench, the Kelp Forest, and the Open Blue
The three core hotspots behave differently in terms of catch size, rarity roll frequency, and crowd competition. The Trench pulls the deepest pools and the heaviest rares, the Kelp Forest offers a balanced mid-tier grind, and the Open Blue is the most consistent spot for raw coin volume.
| Hotspot | Best Catch Tier | Average Coin / Cast | Crowd Level | Notable Fish |
|---|---|---|---|---|
| The Trench | Legendary / Mythic | 8,000–25,000 | Low (off-meta) | Colossal Squid, Abyssal Serpent |
| Kelp Forest | Epic / Legendary | 2,500–6,500 | Medium | Giant Kelp Bass, Lantern Eel |
| Open Blue | Rare / Epic | 800–2,200 | High | Blue Marlin, Mako Shark |
| Volcanic Vent (edge) | Legendary / Mythic | 6,000–18,000 | Medium | Lava Shark, Ember Tuna |
The Trench is the standout for serious grinders because Mythic rarity rolls happen roughly every 60 to 90 casts when paired with a Colossal Bait, which pushes hourly returns well past what any Sandy Shores or Coral Island spot can match. The Kelp Forest remains the safest middle ground for players still building their coin bank, and the Open Blue functions as a fast-respawn zone for steady volume.
The Volcanic Vent counts as a transitional edge between the deep ocean and the volcano island, which is why it appears in both tables. Players who want the highest rare catch density often rotate between the Trench and the Vent in 30-minute blocks, since their spawn timers do not fully overlap.
Why the Deep Ocean Outearns Most Islands
Compared to the rest of the island locations in Fish It, the deep ocean wins on raw coin-per-hour for two simple reasons. The first is rarity weighting: every pool in the zone has its Mythic and Legendary roll bands lifted relative to lower-tier islands, so the same rod and bait produce more high-end outcomes per hour. The second is catch size: the average weight band in the Trench is roughly 4x the average weight on Coral Island, and the sell value scales with weight before rarity multipliers even apply.
A practical test run reported by the community — fishing the Trench for 60 minutes with a fully enchanted Rod of the Depths and Colossal Bait — produced around 480,000 Coins, with one Abyssal Serpent sale accounting for nearly a third of the total. That single data point is roughly double what the same setup pulls on Sandy Shores and roughly 30% above the best hour on the volcano island. The grind is real, but the math favors it.
Rare and Mythic Fish Worth the Grind
The deep ocean's payout story lives or dies on its top-end catches. There are about 14 rare-and-above species pooled across the Trench, the Kelp Forest, the Open Blue, and the Volcanic Vent, and five of them carry the kind of sale value that defines an entire progression arc.
Top Targets and Their Sale Bands
The following table lists the most reported high-value catches with their sell range and the hotspot where each is most reliably pulled, based on aggregated community data as of the September 2026 update. Sell ranges are estimated community figures that may shift with each patch, so verify against current in-game listings.
| Fish | Rarity | Approx. Sell (Coins) | Best Hotspot | Notes |
|---|---|---|---|---|
| Abyssal Serpent | Mythic | 180,000–260,000 | The Trench | Drops Colossal Squid Tentacle (craft) |
| Colossal Squid | Mythic | 120,000–170,000 | The Trench | Required for Trident+ upgrade path |
| Lava Shark | Mythic | 90,000–140,000 | Volcanic Vent | Bridges deep ocean and volcano island |
| Ember Tuna | Legendary | 55,000–85,000 | Volcanic Vent | Frequently used in cooking recipes |
| Giant Kelp Bass | Legendary | 40,000–65,000 | Kelp Forest | Most reliable Legendary roll |
| Lantern Eel | Legendary | 35,000–55,000 | Kelp Forest | High weight variance, heavy hitter |
| Mako Shark | Epic | 18,000–28,000 | Open Blue | Steady Epic income |
| Blue Marlin | Epic | 12,000–20,000 | Open Blue | Best sell/cast ratio at Epic tier |
A full Fish It fish list breaks down the remaining rares and below, but the eight species above are the targets that justify the level grind to 75. Selling them in batches at the Coral Island merchant — rather than the Open Blue floating buyer — gives a roughly 12% bonus thanks to the merchant's Bulk Bonus perk, which is worth the trip back through the whirlpool.
Luck Stacking for Rare Catches
Three systems stack into your effective luck when fishing the deep ocean, and understanding the order matters because the game applies them multiplicatively. Base rod luck from your current Rod of the Depths enchantments sits at the bottom, bait luck from Colossal Bait or Magnetic Lure multiplies on top of that, and active server event multipliers (during storms or limited-time boosts) sit at the very top. Skipping any one layer drops your Mythic roll rate by an order of magnitude.
-
Rod Layer — keep the Rod of the Depths fully enchanted with the +Luck glyph before entering the Trench; an unenchanted rod is the single biggest reason players report dry hours.
-
Bait Layer — Colossal Bait is the deep ocean's default for Mythic chases; Magnetic Lure outperforms it for weight-class rares like the Lantern Eel.
-
Server Layer — limited-time storms multiply all luck by 1.5x and shorten the catch window by roughly 0.4 seconds, which is why the same hour of fishing during a storm outperforms two hours of calm weather.
How the Deep Ocean Compares to the Volcano Island
The volcano island is the natural next step after the deep ocean, and players often ask whether it actually pays better. The honest answer is that the two zones are tuned for different jobs: the deep ocean is a broad farm, while the volcano island is a high-variance rare chase with a much higher entry cost.
Side-by-Side Comparison
| Metric | Deep Ocean | Volcano Island |
|---|---|---|
| Level Gate | 75 | 110 |
| Access Item | Trident (crafted) | Heat Suit (crafted) |
| Average Coin / Cast | 2,500–6,500 | 3,800–9,500 |
| Mythic Rate | ~1 in 80 casts | ~1 in 45 casts |
| Crowd Level | Low to Medium | High |
| Best Use Case | Sustained grinding | Targeted rare chases |
| Burnout Risk | Low (calmer pacing) | Medium (fast catch windows) |
The volcano island pays better per catch, but the Heat Suit requirement, the Level 110 gate, and the steeper competition make it a poor first step. A practical progression path is to grind the deep ocean until your coin bank supports a Heat Suit plus a Volcanic-tier rod, then transition into the volcano island once both are banked. Reversing the order — rushing the volcano island first — is the most common reason players stall out before unlocking the top-end of the deep ocean.
The Volcanic Vent is the bridge between the two islands and the cleanest example of why the deep ocean stays relevant even after the volcano island unlocks. Several Mythic species, including the Lava Shark and the Ember Tuna, only spawn on the Vent's edge, and the Vent's catch window is calmer than the volcano island's central pools, which makes it the friendlier farming spot for long sessions.
Practical Prep Before Your First Deep Ocean Trip
A clean first trip into the deep ocean takes about 20 minutes of prep beyond the level gate and the Trident. Skipping any of the steps below is the most common reason new arrivals burn through bait and walk away with the same coin total they would have earned on Coral Island.
Gear and Bait to Bring Down Deep
-
Rod of the Depths with at least the +Luck and +Weight glyphs slotted.
-
500x Colossal Bait in the inventory — the Trench burns bait faster than lower-tier zones.
-
10x Luck Potion III from the code shop; consume one before each 30-minute farming block.
-
Hoverboard or Sailboat fast-travel token for the return trip to Coral Island when selling.
-
Empty inventory slots — Mythics do not stack and a full bag will block the catch animation.
Session Plan for Maximum Coin per Hour
A simple three-block session plan keeps the grind efficient and avoids the dry-streak fatigue that causes most players to swap zones too early. Run Block 1 in the Trench for 30 minutes targeting Mythics, Block 2 in the Kelp Forest for 20 minutes farming Legendaries to refill the merchant batch, and Block 3 at the Volcanic Vent for 30 minutes chasing bridge rares for the volcano island prep. Selling once at the end of each block — rather than after every Mythic — keeps the Bulk Bonus maximized and saves the round-trip dock cost.
For players who prefer a more laid-back cadence, the Open Blue supports a relaxed 45-minute block that almost never feels pressured, because the catch window is long and the rare spawns are frequent enough to keep the session interesting without demanding strict timing. The choice between tight and relaxed pacing does not meaningfully shift the coin-per-hour curve, which is one of the more underrated strengths of the deep ocean compared to the higher-pressure volcano island.
Frequently Asked Questions
What level do I need to enter the deep ocean in Fish It?
You need Player Level 75 plus a crafted Trident from the Coral Island workbench. The level is enforced server-side, so XP boosts from potions or active codes stack toward the gate but cannot shortcut the level floor itself. Without both the level gate and the Trident, the deep ocean entry stays locked and no bait unlocks the portal.
Where are the best fishing spots in the deep ocean?
The Trench is the highest-paying hotspot for Mythic and Legendary chases, the Kelp Forest is the safest mid-tier grind, and the Open Blue is the most consistent spot for raw coin volume. The Volcanic Vent at the zone's edge is the bridge to the volcano island.
How many coins per hour can I expect from the deep ocean?
A focused hour in the Trench with a fully enchanted Rod of the Depths and Colossal Bait typically yields around 400,000 to 500,000 Coins, with one large Mythic sale driving a meaningful share of the total. Relaxed Open Blue sessions land closer to 150,000 to 220,000 Coins per hour.
Is the deep ocean or the volcano island better for coin farming?
The deep ocean is the better sustained farm because of the lower crowd level and calmer catch windows, while the volcano island is the better rare-chase target thanks to a roughly 2x higher Mythic roll rate. A practical path is to bank in the deep ocean first, then transition to the volcano island for targeted hunts.
What is the rarest fish in the deep ocean?
The Abyssal Serpent is the rarest confirmed catch in the zone, sitting at the top of the Mythic tier with reported sell values between 180,000 and 260,000 Coins. It also drops the Colossal Squid Tentacle, which is a key crafting material for the post-game Trident+ upgrade path.
