# SpawnablePrefabs

Fish-Networking uses a collection of prefabs to manage spawning of network objects across the network. Whenever you instantiate and [spawn](/docs/guides/features/networked-gameobjects-and-scripts/spawning.md) an object on the server, FishNet will use the selected **Spawnable Prefabs** collection to find which object it is and to automatically instantiate and link the objects on all clients.

The **Spawnable Prefabs** collection can be set on your [NetworkManager](/docs/fishnet-building-blocks/components/managers/network-manager.md) component.

{% hint style="success" %}
The NetworkManager will automatically set the **Spawnable Prefabs** to an automatically managed [DefaultPrefabObjects ](/docs/fishnet-building-blocks/scriptableobjects/spawnableprefabs/defaultprefabobjects.md)asset if a custom one is not selected.
{% endhint %}
