I live in the UK. Last year I had a visit from a heron and he cleaned out
all my goldfish.
so since then I have rebuilt my pond and made it bigger so I can switch over
this year to Jap Koi Carp, I have put in a larger better filtration system
and pump, But my only fear is that dammed Heron, so if any one can sagest a
way to stop his visits this year especially after I restock with koi I would
be grateful.

The short version, clutter up the landing area. A heron can have a
6' wing span and can land and walk over to the pond, but won't land in
an area where something will touch it's wings. Some have used
overhead wires. I (With my wife's help.) turned my yard into a
junkyard of ornamental windmill, flags, wind chimes and flower pot
holders with a few plants like 6' dwarf maples and Miss Huff lantana.

This is my most vulnerable time of the year, because I just cut the
lantana brush left from last year's growth, but I suspect the taller
structures like the gazebo and my neighbors 10' fence (basketball
half-court) adjacent to the lantana bed discourage the heron from
landing in that corner of our small yard.
