The usual recommended stocking density for good water quality is 60 Kg
per acre. As the Thames Water Utilities very kindly offer the
information on their website, ( which I noted above, but Kenny is
simply too stupid to read), that the reservoir has 240 acres, and they
have an annual stocking of 30,000 trout if they stick to the usual
average that means 125 trout per acre at about 500 grams each, if they
stock them all at once. Some waters do this. They do not state what
they do here, but they do mention stocking ponds.
