"Enable weight for fish? Useful for fishing competitions" = true

But the fish I caught have no weight

1.16.5 Server: Arclight (https://github.com/IzzelAliz/Arclight)
With Piscary (another fish mod)

It's a bukkit server, those are not supported due to how they change gameplay and code.

Is there any other solution? This server also supports mods.

Not really, unless you can run the server without plugins. In which case just run a normal forge server.

I tried it in singleplayer mode, and there is no weight..

Is it only the Piscary fish that don´t have weight, or what are you saying?

all fish

Unable to reproduce, works just fine with Aquaculture and Piscary together.

to open the weight, in addition to setting "Enable weight for fish? Useful for fishing competitions" = true , is there anything else? thx

No, just enable that config.

Well you need to catch a new fish, after enabling the config. Fish caught previously will not have a weight.

i did this, and i think may be caused by other mods. i will try
and i had another mod about fishing -- fishingoverhaul (a game when you catch a fish)
i will try to delete him and test again

Seems to be an edited question, not the mod. Now the weight is displayed, but it isn't have "Large" or others like the picture above.

oh.. it looks like some have and some don't

Perhaps this is the original look like?

Anyway, thank you very much for your help!
