Hi Alex - There are a lot of health commentaries about 1) fish and which typically have a high mercury content and where they are caught and also 2) the risks of eating canned (tinned) food of all types because of the inner can lining/coating of BPA and the health risks involved with that chemical. Protein doesn't lose it's nutrient quality but canned vegetables do so best to eat fresh veggies and fruit rather than canned.
Some say to read labels carefully to see where fish were caught; avoid Asian waters because of environmental pollution is not a concern in many areas and polluted rivers flow into the sea. Others say avoid Pacific ocean caught because of Fukushima pollution. Others say the smaller the fish, the less mercury contamination because they haven't lived long enough to accumulate much. So sardines are ideal. Smaller herring, also less risk. Same with eating fresh fish... larger types...esp. grouper, tuna, shark etc. have much more mercury contamination.
There are canned products that are now labeled "BPA free" so you can look for that....or those preserved in glass jars.
Again, avoid plastic containers for the obvious reasons.

Editing this to include: Advice is also given to avoid farm raised fish because of the food given plus many of the cages are very crowded which causes other problems. Salmon is often farm raised. In some areas, the fish pens are very large and offer access to more ocean water than others that are in harbors or rivers, apparently.
