Sea Cucumber Stardew: Your Complete Guide to Fishing and Profiting
Catching a Sea Cucumber

Sea Cucumber is available in ocean water at The Beach and Beach Farm from 6:00 AM through 7:00 PM in Fall and Winter. It can also appear through special sources such as garbage cans or the Night Market submarine. Magic Bait bypasses its normal time and season restrictions.

For those impatient anglers, you can also use Magic Bait to catch Sea Cucumbers irrespective of time or season.

Using Sea Cucumbers
Once you’ve nabbed one, what do you do with it? Sea Cucumbers are surprisingly versatile. For fashion aficionados, the creature can be used in a Sewing Machine to create a dyeable Tube Top. If you’re interested in colors, use it as a yellow dye at the dye pots situated in Emily’s and Haley’s house at 2 Willow Lane.

Pond Reproduction
Sea Cucumbers reproduce every two days when the pond has room. The starting capacity is three, and population quests raise the maximum toward ten.
Sale Prices and Processing
| Quality | No profession | Fisher | Angler |
|---|---|---|---|
| Normal | 75g | 93g | 112g |
| Silver | 93g | 116g | 140g |
| Gold | 112g | 140g | 168g |
| Iridium | 150g | 187g | 225g |
Sea Cucumber Roe is worth 67g. A Preserves Jar turns it into Aged Roe worth 134g, or 187g with Artisan. Raw Roe does not receive the Fisher or Angler fish-price bonus.
Fish Pond Output Odds
The generic ocean-fish pond data uses a daily production roll that rises with population: 23%, 31%, 39%, and 47% at populations 1–4; then 55%, 63%, 71%, 79%, 87%, and 95% at populations 5–10. If the daily roll succeeds, a pond below five fish has a 70% chance to select Roe, while a pond at five or more selects Roe at 100%. That makes the overall daily Roe chance 16.1%, 21.7%, 27.3%, and 32.9% at populations 1–4, then the full 55%–95% production chance from five to ten fish.
A Roe output starts at one item and has repeated 20% chances to add another, so there is a 20% chance of at least two Roe and a 4% chance of at least three. A Golden Animal Cracker doubles the final stack.
Lucky Lunch Opportunity Cost
Lucky Lunch uses 1 Sea Cucumber, 1 Tortilla, and 1 Blue Jazz and sells for 250g. With normal-quality base-price ingredients, their direct sale value is 75g + 50g + 50g = 175g, so cooking adds 75g of sale value. With an Iridium Sea Cucumber and Angler, the ingredients are worth 225g + 50g + 50g = 325g, so cooking would sacrifice 75g. Use a normal-quality fish for cooking and sell higher-quality fish when gold is the priority.
Lucky Lunch’s +3 Luck buff is often more valuable than its sale price for Skull Cavern runs. Pumpkin Soup is an alternative from Robin that provides Luck and Defense without consuming a Sea Cucumber.
Fish Pond Options
Choosing the right fish for your pond can be crucial. The Sea Cucumber is excellent for crafting Lucky Lunches, but if you’re looking for profitability, go for the Lava Eel. Other fish like the Sturgeon can yield caviar, and Blobfish have a chance of producing pearls.
