Cheap plant oil can give us healthier salmon
So farmed salmon eating plant diets lack Omega-3 fatty acids, as they usually get that from eating other fish. Farmed salmon can sorta get that back by adding fish oil to their feed, but that costs money. Now, using transgenic plants that put out DHA and fatty acids as feed seems to fill the nutrition gap for farmed salmon.

Apparently the Atlantic Killifish has some sort of rapid evolution gene quirk, which has allowed it to adapt quickly to human polluted waters fast.

Lucky Iron Fish
For rice heavy diet regions where people suffer from iron deficiency, assuming their local water isn't arsenic contaminated (which blocks iron uptake), putting a lump of bio-available iron in water or soup during cooking (10 minutes, with a bit of lemon to improve uptake) had substantial health improvement without the side effects of typical iron supplement tablets.

So these guys made a fish cannon. Apparently spawning salmon seem quite willing to get into the thing too.

University of Rhode Island Make Transgenic Trout that are Myostatin Unhibited So They Have 20% More Meat for Better Aquaculture
I can understand the desire for a higher protein yield in commercial land based aquaculture, but seriously. These fish look like muscle bound gym freaks. People are definitely not going to be buying these fish whole at the supermarket. A secondary issue is that the increased muscle fiber count without a corresponding increase in muscle fats will make the meat lean (which may be a good or a bad thing, depending on the way you prepare fish for consumption). And lord have mercy is these GM trout ever get loose.
