Fishing
Content Expansion 1 is activated on EU #1. It is a guarded content layer over unchanged Worldgen V4, not another biome or generator profile.
Select a Fishing rod, hold right mouse to charge a throw, then release toward clear water. Longer charging throws farther. The hook flies before a hidden, random wait; watch the float and right-click inside the 1.8-second bite window. No wait countdown is shown. Early/late pulls award nothing. Casts wear the rod once; each successful authorized reel awards one catch. Moving or changing dimensions cancels the cast.
River/freshwater can yield Raw perch; Sea/Ocean can yield Raw mackerel. Existing Catfish remains in both catch tables. The server chooses the result using actual water location and its PRNG; these fish are items, not extra simulated mobs. Cook each new fish at a Campfire or Furnace using its separate station recipe. Raw fish restores less hunger and can hurt; cooked fish is safer. Gather shallow Seaweed for rope or dry it in a Furnace for a small food.
