Top 5 Fish Species to Raise in Stardew Valley’s Fish Ponds
A Fish Pond costs 5,000g, 200 Stone, 5 Seaweed, and 5 Green Algae at Robin's Carpenter Shop. Most occupants reproduce until they reach the current capacity; pond requests unlock higher capacity up to the species' limit. Tiger Trout and special entries can use different reproduction rules.

Which Items Can Live in a Pond?
Fish Pond compatibility depends on the occupant’s fish type and pond category. Clam (object 372) is valid: its type is Fish and it carries the fish_crab_pot, fish_ocean, and fish_has_roe tags, so it matches the Ocean Crab Pot Fish pond entry.
Stardew Valley 1.6.15 includes special pond rules for legendary fish and their second-generation relatives. A pond still holds only one occupant type at a time, and fish removed with a rod have normal quality.
Fish That Change Pond Water Color
| Fish | Water | Data condition |
|---|---|---|
| Slimejack | Green | Population 3+ |
| Lava Eel | Red | Population 1+ after the population-2 gate has been unlocked |
| Super Cucumber | Purple | Population 3+ |
| Void Salmon | Dark purple | Population 3+ |
The purple-water fish is Super Cucumber, not ordinary Sea Cucumber.

Roe Processing: Caviar vs. Aged Roe
Only Sturgeon Roe becomes Caviar in a Preserves Jar. Roe from other fish becomes Aged Roe. For ordinary fish, Roe base value is derived from the fish's base price and Aged Roe doubles that Roe value.
| Fish | Roe base | Jar product | Jar base | With Artisan |
|---|---|---|---|---|
| Sturgeon | 130g | Caviar | 500g | 700g |
| Lava Eel | 380g | Aged Roe | 760g | 1,064g |
| Blobfish | 280g | Aged Roe | 560g | 784g |
Five Useful Pond Choices
- Sturgeon — Its exclusive Caviar is required by the Missing Bundle. One mature pond also provides a renewable source rather than relying on repeated catches.
- Lava Eel — Its 380g Roe becomes 760g Aged Roe before Artisan. The pond can also produce Gold Ore, Spicy Eel, Magma Geodes, and current-version Cave Jelly rows at their population thresholds.
- Blobfish — Its 280g Roe becomes 560g Aged Roe or 784g with Artisan. At population 9 its special table includes a 2% Pearl row and a separate 2% row for five Farm Warp Totems.
- Stingray — This is object 836; there is no “Tiger Slimefish” object or pond. Its local output rows are listed below.
- Crab — Ten Crabs in a pond unlock Willy's one-time Pearl dialogue. Crab is also used in Crab Cakes.

Stingray Population-Gated Output Rows
| Required population | Chance | Output |
|---|---|---|
| 1 | 80% | Roe |
| 4 | 5% | Magma Cap |
| 5 | 100% | Roe row |
| 7 | 10% | 2–5 Cinder Shards |
| 9 | 6% | Dragon Tooth |
| 9 | 10% | Battery Pack |
Fish pond produced-item rows are evaluated in order, so displayed row chances should not be casually added together as independent guaranteed outputs.
Crab Cakes Buff
Crab Cakes provides +1 Speed and +1 Defense for 16 minutes 47 seconds. “+33% Movement Speed” is not a separate second movement buff; it was an informal interpretation of the same +1 Speed effect.

Changing the Occupant
Fishing every occupant out does not reset the pond's species. Use the Empty Pond command before adding a different fish. The new occupant then starts its own capacity-gate progression.
