Im running a budget Bisect server to play with my friends, but everytime I activate this mod I get the same error:
io.netty.handler.codec.DecoderException: java.lang.IllegalArgumentException: Unknown recipe serializer
aquaculture:crafting_special_fish_fillet

If you need any additional information to find the bug, lmk. Your mod is very intriguing, and I would love to use it!

Do you have the mod installed on both the client and the server? Are you using a pure forge server or a Bukkit hybrid?

Yeah, it's installed. I have other mods on the server, and they run fine. But for some reason its solely just this one that's giving me problems. I'm using a Forge 1.16.4 JAR to run the server

What Forge version are you using on the server?

The server is working properly now and it is now compatible. Thanks for the explanation!

Glad your issue was resolved!

Its a custom 1.16.4 jar version of Forge.

Could you try with this Jenkins build of Aquaculture 2? (Once it's done building, if you see this reply quickly)

I tried your build, but it came back with crash reports. Here is the output

The version of Forge you're using is older, than the version of Forge required to run Aquaculture 2 now.

Should I download the 1.16.5 version of Forge?

Yes. We require version 36.0.42 or newer, of Forge.
