Strontium Bitchings

Small tinned fish, are the most environmentally friendly form of fish.

Tinned fish keep well, so don't go out of date. There is less waste before the consumer as they are tinned very quickly.

Small fish at the bottom of the food chain are the best ones to eat because of the tropic levels.

I eat sardines as a rule, but I would expect pilchards to be good too. Sardines, being smaller, may have the edge.
