Why would shifting to grains reduce the nutritional value of the fish? Is cat more nutritious than lamb?

  Fish feed consists of small, less desirable fish such as sardines and mackerel. These are rich in omega-3, so shifting to grains reduces the quantity available in the fish.

    OK I get it. You didn't mean the nutritional value of a pound of fish.
