Talk:Genetically modified livestock

Do fish belong here?
Definitions of livestock vary, but most that I have read exclude fish. Wikipedia's livestock article leads with the description 'domesticated animals', a category which in my reading does not include fish. Maybe the GMO fish should be linked in the see also but removed from the lede. Dialectric (talk) 04:01, 16 December 2015 (UTC)
 * Interesting question. I guess it depends which parts of definitions we go with. Many that I have read refer to animals reared "on farms".  Many fish are now reared on "fish farms" so might be considered as livestock in that sense. However, I accept that many definitions go on to list the animals considered to be livestock and fish is often missing from that list.  Fish farming is relatively new compared to the other forms of animal husbandry and I suspect fish are missing from lists because of this.  Regarding the term "domestication".  This means selection of animals (or plants) for any characteristic beneficial to the cultivator.  This is obviously extremely broad and IMHO includes GM-fish.  Happy to discuss further.

 * In my opinion, it hinges on whether or not the fish are being used primarily as an agricultural food source. If they are, then they do qualify as livestock. Thus, the GM salmon raised in fish farms are appropriate for this page, whereas for example GloFish are not. --Tryptofish (talk) 16:54, 16 December 2015 (UTC)
 * None of the example animals in the article are currently being used as an agricultural food source. Some, like the spider-silk goat are never intended for food production. The GM salmon, if included, would be the sole example to meet this criterea.Dialectric (talk) 17:04, 16 December 2015 (UTC)
 * I certainly take your point about GM salmon and Glofish. I would not call Glofish "livestock" (although I suspect the pet industry might).  I'm less convinced about the definition being a food source.  Prior to GM, goats were reared for both food and fibre.  This makes them livestock.  I suggest that after GM for spider-silk, they are still livestock, even though food is not the reason for their production.  By the way, there is another GM animal to meet your criteria - GM cattle which do not grow horns.  I'm getting round to include this. DrChrissy (talk) 17:28, 16 December 2015 (UTC)
 * Yes, I agree it shouldn't be limited to food use, now that I think of it. I'm not sure what exact wording I would use to define it, but it comes down to something like being an animal raised on "farms", to obtain "products" that come from the animal. --Tryptofish (talk) 18:35, 16 December 2015 (UTC)
 * Also, "farm" animals, yes; but pets, no. --Tryptofish (talk) 18:36, 16 December 2015 (UTC)

Does GM include cloning?
I recently read that cloning is generally not considered to be "genetic modification". However, many sources write as if it is included. How should we handle that here? Should we make a statement about the difference but include content on cloning, or, should we avoid mention of cloning at all? DrChrissy (talk) 17:17, 17 December 2015 (UTC)
 * That's a very subjective decision, obviously. I'd say that because cloning, by definition, results in organisms with the same genotype, then it isn't a "modification". Therefore, I would limit this page just to livestock where the intended result of the procedure is to change the sequence of the DNA, rather than to simply replicate it. --Tryptofish (talk) 19:51, 18 December 2015 (UTC)
 * No. Although a lot of genetic modification requires some form of cloning ( in plants at least ). AIR corn (talk) 23:48, 18 December 2015 (UTC)
