Adding to this is the question of vaccines or other treatments such as for sea lice. I would have difficulty calling these "natural"

In response to Brendan canthaxanthin occurs in nature, and can be also be
synthesized. According to a review by the European Commission on the use of
canthaxanthin in animal feeds it does not occur in wild Atlantic salmon, but
is present as 'a minor carotenoid' in wild pacific salmon. The dominant
carotenoid in wild salmonids is astaxanthin which is derived from crustacea
in their diet. Canthaxanthin is similar in colour to astaxanthin, but not
identical - it is slightly yellower - and both pigments are incorporated
into feeds for salmon. The rest of the feed includes components, such as
vegetable oil and vegetable protein, that would not be present in the diet
of salmon in the wild. I would not consider the feed for farmed salmon is
natural for that species even when it is formulated from non-synthetic
compounds.
In my first message of 9 November I quoted a definition of 'natural' and my
argument was that by this definition any food produced by farming is not
natural. This is not to say that farmed food is unsafe or unwholesome
because it is not natural. Given the recorded intrinsic toxicity of some
plants and animals harvested from the wild, and the selection for safety and
wholesomeness that has gone into farmed products over the millennia since
agriculture was first developed, I think I will stick to products of
agriculture rather than forage for natural products.
This discussion is relevant to the general discussion current in many
countries about a move to consumption of more 'natural' foods, that is foods
with lower intensities of processing and less use of additives. What I think
we are discussing here is the label that goes on the product and in my
opinion any attempt to label a product of aquaculture, or agriculture, as
'natural' would be misleading. As I remarked in my previous message relating
to introduced species, boundaries in practice are not as hard as definitions
would wish - could a fish harvested from the wild but has been frozen and
thawed be considered 'natural'? Other people might have different
understandings of what the word 'natural' means, but I would like to know
what this understanding is. Yes, I agree with Richard Lord that development
of farming is a natural product of mankind, but I would not accept that a
product of mankind's endeavours is therefore natural.
