Loftia Nassau Grouper: Location & How to Catch It

Loftia Nassau Grouper is an uncommon fish that can be caught in the Central Lake, located in the Hanging Gardens. This fish is required to unlock the Hammer Lv.2 recipe, like the Seventyfour Seabream.
To catch Nassau Grouper in Loftia, head to the deeper section of Central Lake in the Hanging Gardens. Use a Collector Rod at Uncommon fishing spots, where a Good catch has a combined 44.4% chance of rewarding Nassau Grouper. You’ll need this fish for the Heavy-Weight Titans research bundle, which unlocks the Hammer Lv.2 recipe.
The tricky part of Nassau Grouper is where to catch it. I found my fish in the deeper water, where your chances of finding it are much better.

Loftia Nassau Grouper Location
You can catch the Nassau Grouper in the Uncommon fishing spot in the central lake, especially the deeper section. These spots have medium difficulty, and you will encounter a three-ring fishing minigame.
I should say both locations work, but I recommend searching the deeper section.
| Fishing Spot | Good Catch | Critical Catch |
|---|---|---|
| Central Lake (Regular) | 5.6% (1 fish) | 12.5% (2 fish) |
| Central Lake (Deep) | 33.3% (1 fish) or 11.1% (2 fish) | 25% (2 fish) |

Fishing spots also respawn after approximately 30 seconds. You can return to a depleted spot instead of searching the entire lake for another one.
These percentages apply to the corresponding fishing results, not every cast. That gives the deeper Uncommon spots a combined 44.4% Nassau Grouper probability on a Good result, compared with just 5.6% in the regular lake.
How to Catch Nassau Grouper
First of all, you will need a Collector Rod. This rod will be unlocked through the Hanging Gardens quest progression, including Kassim and Fish Are Friends.
Craft the Rod at the Project Station (Level 1) with the following materials:
| Material | Amount |
|---|---|
| Rattan | 5 |
| Jute | 5 |
| Plastic Sheet | 1 |
| Energy | 5 |

Plastic Sheet is a refined material. If you don’t have one, refine 5 Plastic Discards into 1 Plastic Sheet at a Refining Station. Rattan comes from Rattan Tree Spots in the Hanging Gardens, which you harvest with Pruners, and Jute can be gathered around the Hanging Gardens or from breaking baskets.
After equipping the rod, look for the ripples in the Central Lake. Cast into the water and wait for a bite. Then press the catch button while the indicator is inside the highlighted zone. Hitting the star gives you an instant catch. I’d aim for Good or Critical results because Basic catches only reward Algae at these spots. You don’t need Collector Rod Lv.2, and there are no confirmed weather or time-of-day restrictions for Nassau Grouper.

Make sure you are fishing at the Uncommon spots of the Central Lake, not the rare section.
Also check the Fish Repopulation effort. A Bad status reduces the availability of Uncommon and Rare fishing spots across the Hanging Gardens, while Average and Good statuses improve their availability.
If suitable spots seem scarce, I’d check the effort status before wasting time circling the lake.
What Is Nassau Grouper Used For?
Here is a good reason: Heavy-Weight Titans bundle. It is on page two of the Central Lake Research section.
This bundle requires four fish:
| Required Fish | Best Fishing Spot |
|---|---|
| Seventyfour Seabream ×1 | Deep Lake Common |
| Nassau Grouper ×1 | Deep Lake Uncommon |
| Giant Sea Bass ×1 | Deep Lake Uncommon |
| Southern Bluefin Tuna ×1 | Deep Lake Rare |

Completing the Heavy-Weight Titans research bundle unlocks the Hammer Lv.2 recipe, but you’ll still need to craft the hammer yourself. I recommend catching Nassau Grouper and Giant Sea Bass together because they share the same Deep Lake Uncommon fishing spots and catch probabilities. Then switch to Rare spots for Southern Bluefin Tuna.
How to Craft Hammer Level 2?
To craft Hammer Lv.2, you need Project Station Lv.2, which you unlock by completing the Anadromous Odyssey research bundle. Completing Heavy-Weight Titans gives you the Hammer Lv.2 recipe, but you still have to craft it at the upgraded station.
The recipe for Hammer Level 2 is:
| Material | Amount |
|---|---|
| Hammer | 1 |
| Rattan | 10 |
| Copper Scraps | 10 |
| Rubber | 2 |
| Energy | 7 |
A new level of Hammer lets you break tougher rocks, and you can gather resources from additional spots, including Pine Trees and Mineral Nodes.
