Please advise my grammar

I do not understand your first sentence; please explain more.

The supplier inform me as below
container 1 20mt.,the fish from fishing vessel A.victory, 4mt., the fish from fishing vessel A.Triumph.
I would like to know the supplier separated the fish each fishing vessel in the container by net or not.

Let me get this straight;

There are 2 boats, the 'Victory' and the 'Triumph'?
And you want to know whether the fish caught by the 'Victory' and the fish caught by the 'Triumph' have been put into the same container or separate containers?

The supplier put the fish of Victory and Triumphin one container, I want to know for this container, they mix the fish or separate the fish by net in container.

OK, let's try this:

Could you please let me know whether you used a net to separate the fish from each vessel in the container? Or are they mixed together? We need to know in order to create the report for receiving the fish.

Thank you. I have one question, please suggest me.
"We found the bigeye tuna for container No.12, please let us know the price of bigeye tuna same yellowfin tuna or not.

Thank you very much.
