Install Combustive Fishing on your server

Combustive Fishing lets players fish in lava. It adds a Blazing Fishing Rod and two Nether fish, the Combustive Cod and the Searing Swordfish, and it is a Forge mod for Minecraft 1.16. Every player needs it on their own game as well as the server.

Checked against Combustive Fishing 4.0.0.1 on Forge 1.16.5, October 2026.

What you need

• Forge on Minecraft 1.16.5. Version 4.0.0.1 is the newest on Modrinth, uploaded to Modrinth in February 2023, and its jar accepts Minecraft 1.16.3 up to but not including 1.17 with Forge 34 or newer. Pick Forge and 1.16.5 in JAR Manager and the panel runs it on Java 8 for you.
• Nothing else. The jar names no other required mods and Modrinth lists no dependencies.
• Other versions. Modrinth also carries older Forge builds for 1.15.2, 1.14.4, 1.13.2 and 1.12.2. Modrinth lists no Combustive Fishing build for newer Minecraft versions.
• Players. Modrinth lists the mod as required on both the server and the client.

1. Open JAR Manager, under More in the left rail.
2. Set Server software to Forge and Minecraft version to 1.16.5, then press Apply change.

How it plays

The descriptions below are the mod author's own, from the project page, and only the recipes are checked against the jar:

• Blazing Fishing Rod. It behaves like a normal fishing rod but also fishes lava for fish, junk and treasure, with more durability and enchantability. The recipe is a fishing rod with blaze rods in place of the sticks and a magma cream added: three blaze rods on the diagonal where a fishing rod has its sticks, two string down the right side and one magma cream bottom middle.
• Combustive Cod. Found only in Nether lava pools. It is too hot to eat and explodes when thrown. Dropped into water it cools into a Cooled Cod, which is edible.
• Searing Swordfish. Lives in the same lava pools. Its bill, crafted with a blaze rod, makes a Searing Sword.
• Bone Fish. Found in lava in the Nether and the Overworld. It attracts wolves and ocelots and gives slightly more bone meal than a bone.

The mod has no config file in its jar, so there is nothing to tune in config.

Common problems

• The server stops at start and names combustivefishing. Check Minecraft version in JAR Manager. The jar rejects 1.17 and newer.
• Players cannot join. They need Forge 1.16.5 and the same file. Use Export for players in the Installed view of the Mods tab, then read Join a modded server from your launcher.
• No fish in lava. The project page says the Blazing Fishing Rod is the one that lets you fish in lava. Check you are holding it.
• Other load errors. Fix Minecraft mod and plugin load errors shows how to read the log.
