Hadean Depths
Hadean Depths expands fishing on NeoForge 1.21.4 with more than 50 new fish, rods, tools and a butchering step for the catches.
What it does
Fishing progression is reworked around the new catches. Fish are sorted into rarity types, and they can be found in different biomes and at different heights, times and days, with their own treasure and junk drops. Lava fishing is also added. The advancement tree is expanded to guide players through the new fishing path.
A new butchering mechanic turns caught fish into food and crafting material: a butchering hook is placed down, and a fish is hung on it with a right click. The mod adds 16 food items, 8 tools, 5 fishing rods and an armor set. Its loot tables for fish, junk and treasure are adjustable by server owners.
Hadean Depths is an MIT-licensed open source project published by KaironeyBaloney on 2025-12-22, with its latest NeoForge file, version 1.1.0, dated 2026-03-01. Its files target 1.21.4 only, and the source code and a wiki are publicly linked. It is not on any other loader.
