Prof. David Ma has discovered that marine-based omega-3s are eight times more effective at inhibiting tumour development and growth.
"This study is the first to compare the cancer-fighting potency of plant- versus marine-derived omega-3s on breast tumour development," said the professor in the Department of Human Health and Nutritional Sciences. "There is evidence that both omega-3s from plants and marine sources are protective against cancer and we wanted to determine which form is more effective."
[...] Published in the Journal of Nutritional Biochemistry, the study involved feeding the different types of omega-3s to mice with a highly aggressive form of human breast cancer called HER-2. HER-2 affects 25per cent of women and has a poor prognosis.
[...] Ma found overall exposure to marine-based omega-3s reduced the size of the tumours by 60 to 70 per cent and the number of tumours by 30 per cent.
However, higher doses of the plant-based fatty acid were required to deliver the same impact as the marine-based omega-3s.

That's interesting but TFS specifically mentions "Marine fish oil" and it looks like your links are more concerned with fish feeding on the algae rather than humans although algae could be tasty. Nom nom nom!

I heard that fish get their Omega 3 from the algae, so it's probably better to go straight to the source and get your Omega 3 derived directly from algae. You can purchase it in tablet form (which I do), but it's expensive.
As a vegan, I'm not going to purchase fish oil tablets so it doesn't matter to me (in a practical sense) if that's incorrect.
I know a lot of people say Omega 3 tablets are a waste of money and are completely unnecessary, but there's a lot of conflicting information out there.

Those capsules... are they vegan? Most of the time, they'll contain gelatin... a thing obtained from animal sources, pork skin mainly.
E.g. Blackmores [blackmores.com.au] - scroll down to "A clear, yellow, oblong, soft gelatin capsule"

vegan capsules are made from cellulose.

I doubt cellulose is the only ingredient - human guts cannot break cellulose, therefore it needs to contain a binder.

Nothing suggests the binder need to contain animal products: Water soluble cellulose derivatives exist, and could dissolve readily in the stomach fluids without enzymatic activity e.g. Hydroxyalkylcellulose is used as a binding agent, sodium carboxymethyl cellulose, Hydroxyethylcellulose are used as gelling agents.

Neither did I suggest that.
I only said that one cannot exclude formulations of soft gel capsules that contain animal products.

Add to the above hydroxypropyl methylcellulose [wikipedia.org] if my understanding is correct [wikipedia.org]

Other than the 'for vegans' promise, I see no mention about the substance the capsule is made of.
The biuret test [wikipedia.org]** will indicate if there is any protein in it, it won't say however if those proteins are of animal origin.
** Just in case you want to play with:
Sodium hydroxide and copper sulphate available at Bunnings. Sodium potassium tartrate - cream of tartar in layman speak - available at Coles/Woolworths in the baking sector.

This is the perennial scourge of anyone that chooses to follow a strict diet. You can choose to prepare all your meals from only the most basic ingredients (which incidentally often makes for more enjoyable and sometimes more cost effective, even healthier, meals) and often this is the path of least resistance for most food shopping, or else you're completely reliant on the honesty and accuracy of the food manufacturers and their suppliers.
I strongly suspect that huge numbers of food products have ingredients that do not reflect the labels. People have been bred to instinctively trust big business as authority figures. The whole thing becomes a pragmatic best guess process depending on what the particular consumer is comfortable with.

This is probably because many Omega 3 supplements have rancid oil. Rotten fish oil is unlikely to be as good for you as fresh fish oil.
I've broken open fish oil capsules from different suppliers and some smell rotten and some smell like fresh fish oil (should smell like fresh fish - e.g. faintly/slightly fishy, not strong and smelly).

Probably similar thing for Flax seed oil- lots of polyunsaturated fats go rancid quite quickly.

Marine fish oil is obtained up the food web by predators consuming other predators who consume algae. As with the terrestrial food web, the primary producers in the marine ecosystem are plants, and the primary source of energy in the tropic marine ecosystem is from the sun.
