To catch a sturgeon in Stardew Valley, fish in the Mountain Lake during summer or winter, between 6am and 7pm. Any weather works, although rainy summer days offer better chances. Cast at least three tiles away from shore when possible. This sturgeon Stardew Valley guide covers the fishing requirements, equipment choices and pond upgrades that turn your catch into a source of caviar.
There are two main reasons to keep one: the Lake Fish Bundle needs a sturgeon, while caviar production requires its roe. Before selling your catch, decide which of those goals you want to work towards.
Sturgeon Stardew Valley: Location, Season and Time
The Mountain Lake is the main destination for catching sturgeon. The Stardew Valley Wiki’s sturgeon entry lists the following conditions for catching this fish.
| Requirement | Details |
|---|---|
| Main fishing location | Mountain Lake |
| Seasons | Summer and winter |
| Time | 6am–7pm |
| Weather | Any |
| Fishing difficulty | 78 |
| Movement behaviour | Mixed |
| Helpful casting distance | At least three tiles from shore |
Sturgeon also appear in the Wilderness Farm’s fishing waters during summer and winter. Rain is optional: you can catch one on a clear day, so there is no need to postpone every trip until the weather changes.
Casting distance deserves attention. What matters is where the bobber lands relative to nearby land, rather than simply filling the casting meter. A long cast towards another bank can still leave your bait close to shore.
How to Make the Catch Easier
First, check your rod. The Training Rod cannot catch sturgeon. It only catches fish with a difficulty below 50, which excludes this species. Its larger beginner-friendly fishing bar does not override that restriction.
During the fishing minigame, keep the fish icon inside the green bar until the catch meter fills. Holding the tool button raises the bar, while releasing it lets the bar fall. Repeated presses can help maintain its position. Long holds build momentum, making it easier to overshoot a fish that changes direction.
A higher Fishing skill increases the green bar’s size. Food that temporarily boosts Fishing can help for the same reason. Upgrading to a Fiberglass or Iridium Rod does not, by itself, enlarge that bar; the equipment’s bait and tackle options provide different benefits.
For players with an Iridium Rod, a Trap Bobber gives more room for mistakes. It slows the catch meter’s depletion by 33% when the fish leaves the green bar. That does not guarantee success, but it makes brief losses of control less costly.
The Trap Bobber becomes available to craft or buy at Fishing level 6. Willy sells it for 500g, while crafting requires one Copper Bar and 10 Sap. Only the Iridium Rod and Advanced Iridium Rod can equip tackle, so a Fiberglass Rod cannot use it.
Catching Sturgeon Outside the Normal Season
Magic Bait removes season, weather and time restrictions. However, it does not remove location requirements: you still need to fish in water where the species can normally appear.
This makes it useful if summer has ended and you do not want to wait until winter. You can also continue fishing outside the usual daytime window. It expands the available catches rather than guaranteeing a sturgeon on the next cast.
Magic Bait requires a Fiberglass Rod, Iridium Rod or Advanced Iridium Rod. Neither the Bamboo Pole nor Training Rod can use it. The bait and its crafting recipe are available through Qi’s Walnut Room, so this option depends on having access to that shop.
There are also occasional alternatives to fishing. Krobus may sell a sturgeon on Wednesdays for 200g, while the Traveling Cart can stock one for 600–1,000g. Neither shop guarantees availability.
Keeping a Sturgeon for the Community Center
The standard Lake Fish Bundle accepts a sturgeon as one of its required donations. Bundle items without a specified quality requirement can be donated at any quality, so you do not need to wait for a silver, gold or iridium catch.
Check your bundle progress through the golden scroll icon in the player menu before selling fish. Hovering over an item needed for an outstanding bundle makes that icon pulse.
Buying a fish and catching one are also different goals. A purchased fish can provide an item for donation or pond stocking, but players working on their fishing collection should remember that even harvesting fish from a farm pond does not count towards the Fish Collection.
Building and Expanding a Sturgeon Pond
For the production side of this sturgeon Stardew Valley guide, start with a Fish Pond from Robin’s Carpenter’s Shop. Construction costs 5,000g, 200 Stone, five Seaweed and five Green Algae. It takes two days and occupies a five-by-five-tile area.
Add one sturgeon to begin. Its initial pond capacity is only one fish, so a “full” pond at this stage is normal. Complete the requests to expand it.
| Capacity increase | Requested item |
|---|---|
| 1 to 3 fish | 1 Diamond |
| 3 to 5 fish | 1 Jelly, 2 Maple Syrup, or 1 Pickles |
| 5 to 7 fish | 3 Omni Geodes |
| 7 to 10 fish | 1 Nautilus Shell |
At the second upgrade, supply the requested option, not all three alternatives.
Sturgeon reproduce every four days when capacity allows. One fish is enough to start reproduction; you do not need a pair. Completing a request increases capacity rather than immediately adding fish. You can also introduce extra sturgeon yourself, up to the unlocked limit.
Pond output is random. An empty collection bucket does not necessarily indicate a problem, and population growth should not be confused with a guaranteed roe-production schedule.
Turning Sturgeon Roe into Caviar
Roe means fish eggs. The key production chain is:
Sturgeon Roe → Preserves Jar → Caviar
Place one Sturgeon Roe into a Preserves Jar. The caviar production requirements specify a processing time of 6,000 in-game minutes, approximately four days. The jar uses the eggs, not the whole fish.
The distinction between roe types matters. Other fish roe becomes Aged Roe when processed; Sturgeon Roe becomes Caviar. If you receive Aged Roe, the ingredient came from another species.
Caviar sells for 500g, increasing to 700g with the Artisan profession. Raw Sturgeon Roe sells for 130g, so processing raises the sale value, although it also requires a jar and processing time. Those figures are sale prices rather than a complete calculation of profit after pond construction and upgrades.
Caviar is also an option for the Missing Bundle in the abandoned JojaMart. Keep that potential donation in mind before shipping every jar.
A pond is not the only possible source of roe. After obtaining the power from the Jewels Of The Sea book, fishing treasure chests can contain roe. However, this is chance-based, so finding the book does not guarantee an immediate supply for caviar production.
Selling Your Catch and Choosing What to Keep
An unprocessed sturgeon sells for the following amounts before Fishing profession bonuses:
| Quality | Selling price |
|---|---|
| Normal | 200g |
| Silver | 250g |
| Gold | 300g |
| Iridium | 400g |
Fisher increases fish sale prices by 25%, while Angler increases them by 50%. These fish bonuses are separate from the Artisan bonus applied to caviar.
For your first catches, the useful decision is whether you need a bundle donation, a pond starter or immediate gold. A pond can reproduce from one fish, but its building cost and upgrade requests make it a longer-term commitment. Catching extra sturgeon during an available season gives you more flexibility without relying on random shop stock later.
