🐟 DREDGE Fish Guide: Locations, Times and Equipment

“Day and night” means the fish can be found at either time. Where several methods are listed, any of those equipment types can be used. Place crab pots at the correct depth as well.

No fish in this selection match. Try an English fish or region name, or check the scope of this guide.

A region name alone does not determine whether you can catch a fish. Match water type and method before departure to avoid arriving without suitable equipment.

1. Find the fish’s row and check its time and water type. Even in The Marrows, Coastal and Shallow require different coverage.
2. After researching equipment, buy it from the shop and install it in a compatible slot. Purchasing it or leaving it in storage does not add a fishing method.
3. Rods work at fishing spots; nets work while moving through supported waters; crab pots must be deployed and revisited for collection.
4. Before handing in samples, keep the required regular fish rather than selling everything. Sell surplus to the Fishmonger or Travelling Merchant.

Reaching a region is separate from having a rod for its water types. Research Part counts show the cost to unlock that item; prices are normal displayed amounts. After research, buy and install the equipment before sailing.

1. First sell Coastal catches and buy a Shallow rod. Do not try to catch Gulf Flounder or Grey Eel with the starting Coastal-only rod.
2. Progress the night order to receive a crab pot. Deploy it at a suitable depth, leave cargo space and return to collect the catch.
3. Check a net’s water coverage before deploying it. Anchovy is trawl-only; it cannot be caught by casting a rod into a spot.
4. For Abyssal and Hadal access, begin with the Research Assistant’s samples and parts delivery. Collecting the listed Research Parts does not let you skip that Pursuit.

Starting Coastal rod

Coastal: target Blue Mackerel and Cod with the starting rod. This does not cover Shallow or Oceanic fishing.

Simple Skimmer / Weighted Line

Shallow: buy at Greater Marrow’s Shipwright. Normal displayed prices are $75 / $150. Needed for Gulf Flounder and Grey Eel orders.

Hydraulic Rod

Oceanic: unlock with 1 Research Part, then buy for $410. Install before sailing for Sailfish or sharks.

Flexible Fish Pole

Coastal + Shallow: 2 Research Parts, then $460. Covers both with one rod.

Anti-Tangle Line

Mangrove + Coastal: 2 Research Parts, then $350. For fish such as Gar in Twisted Strand.

Heat Resistant Line

Volcanic + Shallow: 2 Research Parts, then $330. For fish such as Cusk Eel in Devil’s Spine.

Versatile Rod

Coastal + Shallow + Mangrove + Volcanic: 4 Research Parts, then $600. Does not include Oceanic, Abyssal or Hadal.

Sampling Device

Abyssal: receive after delivering the initial samples and Prototype Parts to the Research Assistant. Must still be installed.

Bottomless Lines

Abyssal + Hadal: after the Research Assistant’s equipment unlock, 1 Research Part, then $450. Install before Hadal fishing.

• Check displayed rod prices and parts, then unlock the water type needed for your target fish. This is not a complete comparison of every item’s speed, shape or slot count.
• Eight additional crabs are outside this table’s scope. Use the listed deployment depths for its four crabs and check the pot-placement display as well.

Aberrations have different encyclopedia names from regular fish. Find the base fish below, then use its water type, time and fishing method.

1. First locate the regular fish and use its fishing grounds as a starting point. Shimmering water is a useful aberration marker; check with the spyglass before approaching.
2. Target daytime-only fish by day. Do not look for Sailfish or Cod only at night just because you want an aberration.
3. Aurora Jellyfish and its aberrations require a net. Casting a rod into a fishing spot does not collect them.
4. Look for crab aberrations with pots in the appropriate region. Check pot condition, collect catches and repair as needed.
5. Distinguish aberration requests from regular-fish sample requests. Read the exact name rather than assuming an aberration substitutes for a regular specimen.

• Update v1.2.0 added 10 aberrations; v1.3.0 added crab aberrations and an equipment Aberration Bonus display. Old guides claiming crabs have no aberrations predate those updates.
• This introductory guide does not cover Atrophy’s preference for unregistered fish, bait manipulation or exact aberration probabilities. It lists conditions for finding needed fish through normal methods.

Caught to Order from Greater Marrow’s Fishmonger introduces Shallow fishing, night fishing, crab pots and aberrations in sequence. Hand over the requested fish through the order dialogue before entering the sales screen.

1. First, one Gulf Flounder and one Grey Eel. Buy and install a Shallow rod; a daytime trip can collect both.
2. Next, two Arrow Squid and one Black Grouper. Both are nocturnal, but Squid needs Coastal coverage and Grouper needs Shallow.
3. Use the crab pot received after the night order to collect one Common Crab and one Fiddler Crab. Choose a shallow Marrows deployment spot suitable for both.
4. Deploy the pot, let time pass and transfer catches to the boat. If the required species does not appear, continue checking and deploying. Finish the order before selling surplus.
5. Wait for the next order, then deliver one aberration. This stage requests an aberration rather than a specific regular fish.

Speak to the Research Assistant at Old Fortress, D5 in Stellar Basin. Collect the first three samples, then transport Prototype Parts to progress toward Abyssal equipment and the creature-repelling device.

1. Prepare a Coastal net and Shallow rod. Collect one Firefly Squid and one Glowing Octopus at night; the octopus can also be caught with a crab pot.
2. Trawl Stellar Basin at night to catch one Aurora Jellyfish. Do not keep searching fishing spots with only a rod equipped.
3. After delivering all three species, visit Research Outpost. Examine the equipment on the table inside and load Prototype Parts onto the boat.
4. Return to Old Fortress, deliver the parts and receive Sampling Device. Install it in a rod slot to fish Abyssal spots.
5. Hadal fish require Hadal coverage. Unlock Bottomless Lines with 1 Research Part, buy it and install it. Sampling Device alone does not reach Hadal water.
6. Receive Repulsion Machine from the Research Assistant and connect it to the Generator at Research Outpost. Activate it before heading to the central fishing spots.
7. Collect one Anglerfish, Loosejaw, Giant Amphipod and Snailfish. The first two need Abyssal coverage; the latter two need Hadal.
8. The repulsion effect is temporary. Do not spend too long fishing the center; return to reactivate the device if necessary. Deliver the four samples to the Research Assistant.

• Anglerfish and Loosejaw are available by day and night. The later sample request does not require every fish to be caught at night.
• Managing the creature and meeting rod requirements are separate. Activating the machine does not let non-Hadal equipment catch Snailfish.

Ask the Travelling Merchant about exotic fish to start the Pursuit. Targets are Oarfish, Gulper Eel, Goliath Tigerfish and Coelacanth. Catch them, then report each discovery’s location individually.

• You do not need to keep the fish. Locations can be reported after selling them. Each report rewards 2 Research Parts, for 8 across all four.
• A normal exotic spot is depleted after its single catch. Do not expect regular respawning. The Iron Rig’s Exotic Bait and exotic aberrations belong to separate additional content.
• Explosives are needed to reach Goliath Tigerfish and Coelacanth. Unlock them through the main Gale Cliffs Pursuit, then restock from the Travelling Merchant or another supplier before sailing.

Read each figure’s dialogue and deliver one regular fish at a time in the requested order. Since v1.1.0 their request timers have been removed, so you can unlock the required equipment before continuing.

• Selling to the Fishmonger or Travelling Merchant is separate from handing in a figure’s request. Reserve the needed samples before selling surplus.
• The locations below are where you meet the figures. Their fish may come from different regions.

Cod is a regular fish. Collect five by day with Coastal fishing in The Marrows and bring them to the northern shrine. This is not a requirement for five Cod aberrations.

1. Prepare five regular Cod using a Coastal rod or net. Reserve them before selling everything to the Fishmonger.
2. Take them to the shrine north of Greater Marrow and fit Cod into its offering grid.
3. Collect Sinew Spindle after the offering. Even with a special rod, check the destination fish’s water type.

Fit fish into each shrine’s offering grid, rotating them when several are required. Reserve the right numbers before selling. You can deposit distant-region fish over several trips instead of carrying them all together.

The Marrows: Cod shrine

Five regular Cod. Rewards Sinew Spindle for Coastal and Shallow fishing.

Gale Cliffs: Crab shrine

One Decorator Crab and two Rock Crab. Rewards Mouth of the Deep crab pot. These two crabs’ deployment depths are not listed in this guide.

Stellar Basin: Shark shrine

One each of Hammerhead Shark, Bronze Whaler, Blacktip Reef Shark and Ghost Shark. Rewards Viscera Crane. The first three are Oceanic; Ghost Shark is Abyssal.

Twisted Strand: Aberration shrine

One aberration of any kind. You do not need to fill every grid space. Rewards Tendon Rod for Shallow, Mangrove and Oceanic fishing.

• The three tablets used for Devil’s Spine’s main story are separate from these four equipment shrines. Receiving four equipment rewards does not certify every delivery branch is complete.
• Blacktip Reef Shark is nocturnal; Bronze Whaler is daytime. Clear cargo space and make separate trips instead of trying to carry every shark together.

Check equipment, time, fishing ground and delivery recipient in that order. Similar fish names do not imply the same methods or uses.

Researched a rod but still cannot fish

Check that it has been bought and installed. A rod in storage adds no fishing capability.

Cannot fish near the same island

Check Coastal, Shallow, Oceanic or another required water type. Do not choose equipment from the island name alone.

Searching for Glowing Octopus with a Coastal-only rod

Use a Shallow rod at night or crab pots in the same region.

Cannot find an Aurora Jellyfish fishing spot

Trawl Coastal waters at night. It is not a rod-caught fish.

Waiting for night for every Abyssal fish

“Day and night” entries work at either time. Fangtooth, Barreleye, Anglerfish and Ghost Shark are not night-only.

Stopped the central creature but cannot catch Snailfish

Check Hadal rod coverage. The repulsion machine does not add water types to your fishing equipment.

Thought selling an exotic fish made the Pursuit impossible

Choose the Travelling Merchant’s exotic-fish dialogue and report its location from the catch record.

Took aberrations to sell to the Collector

Sell fish to the Fishmonger or Travelling Merchant. The Collector is not a fish buyer.

Base-game fishing conditions, reflecting Pursuit and aberration changes in free updates v1.1.0–v1.3.0. Checked PC update v1.5.3 (September 18, 2024) and the October 3, 2025 announcement without a version number. Source review date: October 2, 2026.

This introductory guide excludes The Pale Reach’s Ice fish and The Iron Rig’s additional fish and bait. If you have that content installed, check its additional encyclopedia entries separately.
