Fish Mark - Vietnamese or Chinese

The mark on this earthenware Bowl is unclear. I can see a fish mark but nothing more. I have checked BISPM etc. but am struggling to identify the maker. I think it has an eastern influence? Your help much appreciated, many thanks.

I think it’s vietnamese. I’m not seeing the double fish of Christine Smith and it’s not her slipware. And Jeremy Leach always combines the fish mark with his JL etc marks and, again, it’s not his style. So I think it’s Asian, not British.
