I am very keen on bird life and I greeted his news with delight! But it raised a question and an answer in my mind!
The answer was that the herons presence was probably why we haven't ever spotted any of the 5 grass carp that we released into the pond last year!
The question is...
Was it a good idea to stock the herons larder at all?
The pond had extensive grass growth from the banks, which amongst other problems threatened to block the outflow pipe which ultimately would cause the back of the pond to collapse! So, we bought the fish as the recommended way to control grass growth!There has been no evidence that the grass has been reduced at all. But I have reservations that maybe the low level pond life like dragon fly larvae might have already suffered too...?
Opinions welcomed, either respond on this blog, or tweet me, @Fron_Rafel with your view!
By the way, the fish were not inexpensive.
