Stock a Water Body with Fish to Build a Population
Catch Fish to Release
First, catch several fish of the species you want to establish. Each fish you catch becomes a unique item with its own stats. You'll need multiple individuals to create a sustainable population.
Release Fish Into Your Chosen Water
With a caught fish in your inventory, approach a river, lake, or pond and use the release mechanic (usually right-click with the fish item, or via a mod menu). The fish enters the water and becomes part of that location's population.
Watch Your Population Grow
Once released, fish will breed and their numbers increase over time. The population size affects catch rates—more fish means more bites. Different species have different growth rates and environmental preferences, so match fish to appropriate water types (cold streams for
trout, warm lakes for bass, etc.).
Stocking takes patience but creates a permanent fishing spot tailored to your preferences. Return regularly to harvest sustainably without depleting your stock.
