Peter Davey (Have Your Say, June 13) is correct that there should be greater effort put into the farming of fish.

At present virtually all salmon and trout consumed is farmed. There are also vast production units for sea bass, prawns, sea bream, mussels, oysters and tilapia.

In North America and Canada there are huge lobster farms.

It is also possible to find farmed halibut and turbot, so, Mr Davey, we are well on our way to providing sustainable fish stocks to feed the world.

It is therefore a peculiar perception that requires the public to demand ‘wild’ salmon or ‘wild, sea bass when, all things considered, fish is more or less the only food that is still available wild.

Imagine a visit to Tesco with a demand for wild peas or wild beef!

Fish is over harvested, not by us, as our fisherman are the only ones in Europe who even concede the existence of a Common Fisheries Policy.

The rest of Europe carry on plundering as they always have done with not the slightest regard to the future.

Japan’s demand for tuna has seriously affected world stocks.

One day, Mr Davey, all fish will be farmed.
