Yes or No?

actually there are fish in the ocean that already exist that can 'turn on ' so to speak.


it isn't hard to think that there may also already be existing species that have as yet have not been discovered.

remember it wasn't long ago that giant squid were myths and the coelacanth was thought to be extinct.

the fact that scientist are genetically engineering fish isn't all that far fetched..we see it in other species and animals.

ps..I don;t care for the glow in the dark fish..

I wouldn't buy them but, in the right setting, they might be cool to have. If you kept them in a dark room with only the black light, you'd have no algae problems.

I thought it was interesting how the article mentioned using them as water quality indicators. However, as is a concern with all GMO's, what would happen if they got out and their artificial traits were introduced into natural populations? That's the only real concern I have about them.

NEVER! i dispise dyed fish that is one thing that really ticks me off!

They're not dyed. They are a genetically modified organism (GMO). What they do is, isolate a gene from another organism (in this case, the gene(s) for color in coral) and add it to the DNA of the danios using complex enzyme/DNA reactions and, I'm assuming, danio eggs. The eggs are then allowed to develop into fry which carry the gene, causing the fry to express the unique color trait in their skin. There is no dye involved. As far as the fish are aware, they are just normal, everday, ordinary danios......that happen to glow. Depending on how the gene is added and whether or not it is considered to be "dominant" or "recessive," or, if it is present on both paired chromosomes that deal with color in the danio, the trait may be able to be passed on to the young of the altered fish.

Regardless, no dye is involved. The fish are born with the color you see.

no - if you like everything to be natural and organic
or
yes - if you think it's cool

As long as the fish do not have any problems resulting from the addition of the gene, i think its fine.

Science should be dedicating itself to more important things than making fish glow.... :huh:

 

[Marinemom]

I agree. Science needs to concentrate on more inportant issues than wheather or not a fish glows.

well, there's probably other implications to the procedure (such as gene therapy - replacement of "faulty" genes leading to debilitating diseases). The fact that it glows was probably an easy way for them to tell whether it had worked or not.

No. Too much inteferance for me. I prefer natural looking things. I prefer wild striped fresh water angelfish than any of the others. That's just me. I think nature is pretty perfect and don't think it should be changed at all.
