[QUOTE="Oldvatr, post: 2076610, member: 196898"] One main reason why we are encouraged to eat fish is for the omega-3 oils and vitamins that come from them. Artificial fish flesh will need to have these added to provide this vital nutrient. Here is a discussion document on fish oil vs plant based oils [URL]https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3705349/[/URL] There is a new factory opened up in Spain to produce plant based Vit B12 and Omega-3 oils. The process starts with algae in a large vat, and a very complex process involving high temperatures, constant agitation, oxygen and hormone addition via aerators, and then a concluding step at ultra high temperatures to kill off the algae since it is harmful to human digestive tracts. Then the powder is further chemically processed to extract each of the required supplements. Each VAT takes several months to brew a batch of algae to maturity, and it cannot be re-used The firm has started selling supplements suitable for vegans at very high price compared to the animal based equivalents, and all three supplements are poor biovalency so that they are not very effective (DHA / EPA). The plant consumes very high amounts of electrical energy and fresh water, as well as growth hormones and other feeding chemicals and fertilizers. The effluent has tp be further treated since it is not safe to be released into the groundwater system. This is supposed to be a sustainable process to save the planet? The factory by the way produces copious methane and CO2 from the contents of the VAT. [/QUOTE]
