Fishing junk

Fishing junk is the least valuable category of fishing loot. In open water a catch is junk 10% of the time in a biome with fish (10.53% out of open water, where treasure can't be caught) and 95% of the time in Mushroom Fields and the Hell and End biomes, which have no fish (every catch out of open water). In 1.12.7-beta junk was the most common catch, 62.5% of open-water catches in a biome with fish. Luck of the Sea lowers it (see Fishing#Choosing the catch).

Before 1.12.5 the junk table couldn't be loaded: a trailing comma after the fish bones entry made the file invalid JSON, so in 1.12.4 a junk catch gave nothing. 1.12.5 removed the comma, and junk catches give items again. Biomes added by other packs or mods are in none of the pack's climate tags. Since 1.12.7-beta those tagged as oceans or beaches fall back to the temperate saltwater table, and the others get the same fallback junk as the biomes without fish (see Fishing#Other biomes).

Loot

The table below is the junk table as it is written. All biomes share the base items. Three groups of biomes add one or two items of their own, which changes every item's share.

Item	Count	Weight	Share (most biomes, of 78)	Jungles (of 88)	Swamps (of 93)	Dripstone and Lush Caves (of 88)
Lily Pad	1	17	21.79%	19.32%	18.28%	19.32%
Sturdy Leather	1	10	12.82%	11.36%	10.75%	11.36%
Fish Bones	1	10	12.82%	11.36%	10.75%	11.36%
Water Bottle	1	10	12.82%	11.36%	10.75%	11.36%
Estus Ash	5	10	12.82%	11.36%	10.75%	11.36%
Nautilus Shell	1	10	12.82%	11.36%	10.75%	11.36%
String	1	5	6.41%	5.68%	5.38%	5.68%
Stick	1	5	6.41%	5.68%	5.38%	5.68%
Ink Sac	10	1	1.28%	1.14%	1.08%	1.14%
Bamboo	1	10	—	11.36%	—	—
Frog	1	5	—	—	5.38%	—
Tadpole	1	10	—	—	10.75%	—
Axolotl	1	10	—	—	—	11.36%

Jungles are Jungle, Sparse Jungle and Bamboo Jungle. Swamps are Swamp and Mangrove Swamp. Multiply a share by 0.1 for its chance per catch in open water in a fish biome (for example, a lily pad is 2.18% of all catches). Fish bones come from their own loot table, matcha:materials/fish_bones; since 1.12.6-alpha it gives a bone, which plays the fish bones catch sound and unlocks the Angler's Almanac entry.

Estus Ash was added to junk so that players on Peaceful can get it. Most junk plays the junk catch sound. Nautilus shells, fish bones, axolotls, frogs and tadpoles have their own.

History

0.5-alpha	Swamps get their own junk.
1.10	Biomes without fish fall back to junk at weight 85.
1.12.1-alpha	Added Estus Ash.
1.12.4	Fish bones moved to their own loot table. The junk table was left with a trailing comma, so the game can't load it and junk catches give nothing.
1.12.5	The trailing comma was removed, so the junk table loads and junk catches give items again.
1.12.6-alpha	Junk fish bones are bones instead of ender pearls.
1.12.7-beta	The biome tables and the fallback junk became one weightless entry, so junk went from 10% to 62.5% of open-water catches in biomes with fish.
1.12.8-beta October 23, 2026	The biome tables and the fallback junk weigh 85 again, so junk is back to 10% of open-water catches in biomes with fish, and 95% in biomes without.
1.12.9 October 31, 2026	The fallback junk is reached through the new gameplay/fishing/biomes table, whose entry has a quality of +1 instead of −1, so in biomes without fish Luck of the Sea III leaves junk at 92% of open-water catches instead of 88.66%. Guardians and elder guardians no longer drop junk in biomes with fish.
