11Overview22Fish pond breeding allows you to raise and breed fish on your own property in Starsand Island, producing eggs that can be hatched into new fish. This system works alongside the main fishing profession and the Aquarium feature, giving you a passive source of fish without needing to visit fishing spots. Setting up a fish pond requires progress in the Angler profession and specific crafting materials.44Fish ponds come in three sizes, each with different footprints and oxygen capacities. The oxygen level of your pond determines how many fish it can support at once, and maintaining adequate oxygen is essential for successful breeding.67Getting Started89Prerequisites1011Reach at least Intermediate Angler certification from Delphin at the AquaBlue Outpost.Purchase the Small Fish Pond blueprint from the AquaBlue Outpost shop.Purchase the Chopper II blueprint to craft Fish Feed (the basic Chopper cannot produce the correct feed grade).Have available land on your property (Hopeland, Cloudrest Lake, Blue Beach, or Windflute Island) to place the pond.1213Placing the Fish Pond1415Open Build Mode (C key) and place the Small Fish Pond on your property. The pond requires a flat area and cannot overlap with other structures. Once placed, you can interact with it to access the pond management interface.1617Pond Sizes1819Three fish pond sizes are available, each purchasable from Delphin at AquaBlue Outpost. Larger ponds support more fish and have higher oxygen capacity, but require more space on your property.2021Pond TypeGrid SizeOxygen CapacityUnlock TierBlueprint PriceSmall Fish Pond8 x 812 O2Intermediate Angler~2,500 CoinsStone Fish Pond14 x 1712 O2Senior Angler~4,500 CoinsMedium Fish Pond20 x 2040 O2Senior Angler~6,500 Coins2223The Medium Fish Pond is very large and takes up almost an entire plot of land. Plan your property layout carefully before placing one.2324Oxygen System2526Each fish species consumes a certain amount of oxygen. The pond's total oxygen capacity determines how many fish it can hold. If the oxygen level drops too low, fish become stressed and stop producing eggs. Maintain adequate oxygen by not overstocking your pond.2728The Small Fish Pond and Stone Fish Pond each have 12 O2 capacity.The Medium Fish Pond has 40 O2 capacity, supporting significantly more fish.Monitor the oxygen meter on the pond's management interface to avoid overstocking.2930Expansion Materials3132Each pond type must be upgraded with an incubator before it can breed fish. The incubator expansion requires the same materials for all three pond sizes:3334MaterialQuantityGlass Pane4High-Performance Wire Set2Iron Ingot43536Adding Fish3637Interact with the pond and select the stock tab to add fish from your inventory. Fish you have caught while fishing can be placed into the pond. Each fish consumes oxygen based on its species, so check the oxygen meter before adding more.3839Place at least one male and one female fish of the same species into the pond. Having both genders increases the chance of egg production.Fish gender is shown in the item tooltip when you hover over them in your inventory.Different species can coexist in the same pond, but breeding only occurs between fish of the same species.More fish of the same species in the pond increases the egg generation rate. Multiple breeding pairs produce results faster than a single pair.4041Installing the Incubator4243To enable egg production, you need to upgrade your pond with an incubator. Without the incubator installed, fish will not produce eggs regardless of how well they are fed.4445Interact with the fish pond and switch to the Incubator tab.Gather the expansion materials: 4 Glass Pane, 2 High-Performance Wire Set, 4 Iron Ingot.Build the incubator using the materials.Once installed, the incubator allows your fish to produce eggs when properly fed.4647Feeding and Egg Production4849Crafting Fish Feed5051Fish Feed is crafted at the Chopper II station using fish or other aquatic materials. You will need at least 10 portions of Fish Feed to start the breeding cycle. Place the feed into the pond through the management interface. The basic Chopper cannot produce the correct grade of Fish Feed, so make sure you have the Chopper II blueprint.5253Egg Production Timeline5455After placing feed in the pond, fish will begin producing eggs within 1 to 2 in-game days.You will receive a morning notification that there is "something extra" in the pond.Interact with the pond to collect the eggs from the stock tab.Eggs are placed in your inventory and can then be loaded into the Incubator tab to begin hatching.More fish of the same species in the pond increases the chance of eggs being produced each day.5657Hatching Eggs5859Once you have collected eggs, switch to the Incubator tab on the pond and place the eggs there. Hatching takes a set amount of time depending on the fish species. When hatching is complete, the new fish appears in the pond automatically.6061Common fish species hatch faster than rare or deep-sea varieties.The incubator can process one batch of eggs at a time.Hatched fish count toward your Islandpedia collection.Hatched fish can be placed back into the same pond or moved to a different pond or the Aquarium.6263Stone Pond vs Small Fish Pond6465Players have widely reported that the Stone Pond produces eggs more reliably than the Small Fish Pond. If you are not seeing eggs after a full in-game day with the Small Fish Pond, try the following:6667Craft a Stone Fish Pond and place it on your property.Build the incubator upgrade on the Stone Pond using the same materials (4 Glass Pane, 2 High-Performance Wire Set, 4 Iron Ingot).Transfer all your fish from the Small Pond to the Stone Pond.Stock the Stone Pond with Fish Feed.You should see eggs the very next morning.6869FeatureSmall Fish PondStone PondMedium Fish PondGrid Size8 x 814 x 1720 x 20Oxygen Capacity12 O212 O240 O2Egg ReliabilityModerateHighHighUnlock RequirementIntermediate AnglerSenior AnglerSenior AnglerBlueprint Price~2,500 Coins~4,500 Coins~6,500 Coins7071Breeding Workflow Summary7172Here is the complete workflow from start to finish for breeding fish:7374Reach Intermediate Angler and purchase the Small Fish Pond blueprint from Delphin.Place the pond on your property and build the incubator upgrade.Catch fish (at least one male and one female of the same species).Place fish in the pond.Craft Fish Feed at the Chopper II and stock the pond with at least 10 units.Wait 1 to 2 in-game days for eggs to appear.Collect eggs from the stock tab and place them in the Incubator tab.Wait for hatching to complete. New fish appear in the pond automatically.Repeat. Keep the pond stocked with feed to continue the breeding cycle.7576Tips for Fish Pond Breeding7778TipDetailsKeep feed stockedFish stop producing eggs if the feed runs out. Check and refill every few days.Breed valuable fishRare fish from deep-sea zones can be bred in ponds, providing a renewable source of high-value fish for selling or gifting.Use ponds for quest fishIf an NPC requests a specific fish species via the Bulletin Board, breeding that species in your pond saves time compared to fishing for it.Expand your operationPlace multiple ponds on your property to breed different species simultaneously. Each pond operates independently.Upgrade to Stone Pond earlyIf you are having trouble getting eggs from the Small Fish Pond, upgrading to the Stone Pond is the most reliable fix.Watch oxygen levelsOverstocking a pond reduces oxygen and stops egg production. Remove excess fish if the oxygen meter drops too low.7980Related Articles8081FishingAll FishAquariumChopperDeep-Sea Fishing ZonesAquaBlue OutpostAngler Trial WalkthroughsIslandpedia
