What is wrong with intensive fish farms is that fish were never designed
to live in cramped confinement with other fish. Crowded fish are a hotbed
of fish disease and parasites; making them smaller weaker and therefore
less profitable. To overcome the heavy infestatitons of parasites and
disease they are heavily medicated with insecticide and antibiotics. So,
number one what's wrong is the uptake of chemicals from eating the fish.

The second, is that fish farmed in sea and rivers, contaminate the sea
and river bed (therefore the natural ecology) with their medicated waste;
and they are also a source of infection to wild species in the area.

(in case you think the above only happens in the third world, some of
the worst examples have been in the UK, USA and Norway.)
