Jamaalish - Most farmed carp (China) has about 250mg of O-3 per 100g, if that. And even that's assuming the carp are grazing on the right species of algae in the pond water or getting it through their feed. Any oil that is captured from farm species trimmings would go into other animals' feeds. The lipid content and quality would be too variable to chase pharmaceutical markets.

From the Tocher report I just posted a moment ago on pg 12, section 8.3:

Fish species at lower trophic levels, specifically herbivorous/omnivorous fish such as carps, tilapia and pangasius, may have (slightly) better capacity to digest cell walls, if they have B-glucan components, due to the possible presence in the intestine of enzyme activities (e.g. cellulases), whether of endongenous or more likely, microbial origin....Similarly they are not high fat fish and so can only provide a limited 'dose' of EPA and DHA to consumers



Fishmeal is mostly protein, usually a minimum of 65% and some ash, etc. Figure 3 is a bit confusing - Chinese production of carp for their own domestic consumption is huge. It's hard for Americans to grasp 1.3 billion people and their consumption needs (take a look at what's happened this summer since the outbreak of ASF in their pork production - they are buying up all the pork from Eastern Europe to make up for their shortage). So, because the production of carp is so large even with minimal O-3 in the fish itself it seems like on a total basis that it would be a lot of O-3 availability - but, that's the scale of the sheer carp production volumes involved. But, I see how you were reading the UN FAO chart the way you were. -SK
