[DIYbio] Stop Frankenfish?

OMG (GMO)... Just came across this :P 

It's just ridiculous. 


Firstly, they "throw all GM salmons in one bottle". If you add junk DNA, it will not grow faster than others. Only if you add growth hormone, it will. 

>MORE CARCINOGENIC: GMO salmon has 40% more IGF1, a hormone linked to prostate, breast and colon cancers in humans.


This is just bullshit. Yes, they have the protein. If you eat 40% more salmon, you also consume 40% more of the hormone. 
The hromone is likely degraded in the stomach, under acidic conditions. Just saying. 


LESS NUTRITIOUS: GMO salmon has the lowest omega-3 to omega-6 ratio of any salmon.


I am sure, if you feed a "GM salmon" (Which modification in this particular case?!) with Omega6 rich algae, it contains more omega6 than salmon feed with monoculture corn. 

LIKELY TO CHANGE THE BACTERIA OF YOUR GUT: Horizontal gene transfer, where the bacteria of the human gut takes up modified DNA from GMO foods during digestion, has been shown occur with soy and is likely to happen with GMO salmon, too.


So what?! 
Not to add, it is highly!!! unlikely. But not impossible. 
It is as likely that the bacteria take up unmodified DNA as that they take up the modified DNA. They should learn about genetic engineering before posting bullshit. The DNA is stably integrated into the genome. 
IIRC, this study took a kanamycin marker and selected for gene uptake. Else even more unlikely to propagate succesfully. 

Ok, let's assume the bacteria have taken up the growth hormones. Do they even express it? If so fine. The bacteria won't be toxic. And you won't grow by eating them, leave alone by touching them. 


>ALL MESSED UP: GMO salmon has increased frequency of skeletal malformations like "humpback" spinal compression, increased prevalence of jaw erosions or "screamer disease," and multisystemic, focal inflammation in its tissues.


If they give a good source for this I'd believe them. "too much" growth hormone may case the skeleton to grow abnormal. But no 2 fish in nature with exactly same growth hormon level :P 

However, they are just speaking of GM in general, so this statement is just junk too. 

Tissue inflamation due to growth hormone? Don't think so. At least, somatotropin was/is sold as an anti-aging drug, doing exactly the opposite. 


>NOT GOING TO SAVE WILD SALMON: The main justification for GMO salmon is that it could reduce the pressure on wild fish stocks, but consumption isn't the primary pressure on wild Alaskan salmon, destruction of their habitat is.


Ok, but not allowing GMO fish also won't helo the natural stocks :P 



  • >Ate wild fish for feed (though the make up of the diet can vary considerably)
Is this smart? Each step in the food chain only accumulates 10%. 
100kg Algae -> 10 kg fish1 -> 1 kg salmon.
Why not consume fish1 instead? 

>The farm did not contain wastes - uneaten feed, feces and possibly harmful chemicals
  • A professor of mine stated once: 
"Just have a look at how much organic products there are. Organic food means much more efforts to grow - so it's just not realistic that they really all were grown according to organic standards" 

Their page also does not feature a comments feature - usual for superstituos GMO opponents. 


Any thoughts?
