While I'm glad that there is a fish farm to replenish stocks after a pollution, I can't help thinking that this is a bone we are being thrown to keep us quiet about the long-term degradation of our aquatic - riverine, in particular - environments by abstraction, eutrophication and "drainage engineering" (or whatevever the buzzword is now) to remove all water as quickly as possible to protect (why bother?) the dungbrains who buy houses (which ought to be uninsurable) built on flood-plains by greedy fly-by-night developers.
Where, may I ask, are they farming the water-plants, the Gammarus and hoglice, the may-, caddis- and stone-fly larvae necessary not only to re-stock their own kind, but to feed the fish that are been stocked almost cosmetically?
They aren't? Then what are the fish going to eat?
Then there's shelter, fish passes and spawning beds...
