Fishing/Spawn

Schools of Fish

Schools of fish or floating debris appear at set locations along coastlines and rivers. Similar to the schools of fish particular to the Stranglethorn Fishing Extravaganza, players can catch specific fish and valuable items when their cast lands in the school. After several fish are caught, the school will disappear. Over time, schools will respawn in a similar way to mineral nodes or herbs.

They do, however, show up via the Fish Tracking.
