GloFish: Genetically modified danios | |
psuklinger Fingerling Posts: 31 Kudos: 12 Votes: 1 Registered: 03-Aug-2006 | These are exactly what I have, and exactly as they were explained to me. My LFS had ruby red ones, I have 10 of them, then they got in Orange ones and Green ones... I got 5 of each... kinda expensive (10 bucks a piece) but worth it. Every week I go back looking to see if they get different colors in, they guy there told me their hoping they come out with a blue one... I'll get 5 of them too. edit* mine look good, not plasticy ... the orange is a yellow orange and the green is neon green. none glow in the dark. Some of the red ones I got were some and have grown and full in color |

mughal113 Big Fish Posts: 343 Kudos: 160 Votes: 64 Registered: 16-Jun-2006 | I can't understand why they have a notice saying "Not to be released in nature at any cost" on the web sites and on the display tanks when these fish are so safe. Dont they have doubts in their minds? They sure do. "The hybrids found in the hobby are not natural." Hybridization is believed to have led to the evolution of species and is a totally natural phenomenon if u think out of the scope of ornamental fish. "The initial portion of DNA from the jellyfish was merely to give the first cell an "idea" of the gene to make." So a "foreign substance" WAS inoclutaed into the zygote. Anyway, Im neither promoting nor defending any idea. I was just saying what I felt right. Not imposing my opinion on any body else. Cheers! |

Natalie Ultimate Fish Guru Apolay Wayyioy Posts: 4499 Kudos: 3730 Votes: 348 Registered: 01-Feb-2003 | "So a "foreign substance" WAS inoclutaed into the zygote." It's not a foreign substance. As said before, all DNA is exactly the same in all organisms and the only difference between jellyfish DNA and danio DNA is that some of the nucleotides (there are only four of them) are in a different order. EDIT: And how do those hideous hybrids found in the aquarium hobby relate at all to naturally occuring hybrids between closely-related species that live in the same habitat? If the hybrids being sold in the hobby were hybrids that occur in nature and were marked as hybrids, then I would not have a problem with it. But the hybrids sold in mass quantities in stores are not between closely related species or species that occur together in nature, are usually deformed and sterile, and do not have traceable lineages, are a completely different matter altogether. I'm not your neighbor, you Bakersfield trash. |

You'll be hard-pressed to find any evolutionary biologist who will agree on your assertion. Speciation occurs via environmental differences that affects a whole population of animals, as opposed to having two distinctly different species interbreed. Were this the case, you'd surely be seeing more hybridized animals in nature. |

Dont they have doubts in their minds? They sure do." No aquarium fish should be released into nature. They aren't doubting the health and well-being of their danio, they are simply following a principle. My guess as to why they stated this explicitly is that they are trying to prevent hobbyists from doing "experiments" and using the danios to test for pollution themselves. EDIT: Huh, the last three posts came at 16:26, 17:27, and 18:28 local time. |

fish patty Fish Addict Posts: 539 Kudos: 223 Votes: 255 Registered: 04-Oct-2006 | I'm thinking that since the Danios breed true to their coloring...... if some were released & lived & bred........ then they would be pretty noticeable swimming in streams & people that didn't know about them would report them & wonder what was going on with these suddenly appearing strange glowing fish in their waters. A big to do about them would occur with a lot of publicity & people wondering just how safe they were & how unnatural they looked. The glofish company would then receive a lot of investigation & unwanted negativity concerning their fish............. much as they are receiving here on this thread. That's my guess anyway. |

Cup_of_Lifenoodles Fish Guru Posts: 2755 Kudos: 1957 Votes: 30 Registered: 09-Sep-2004 | What I'm reading is that: 1. The observed natural hybrids showcased in said write up is ba 2. Instances of animal hybridization, i.e. dipterids were performed in an in-lab setting, thus nullifying any potential natural institutions it might possibly address 3. Proof of commonplace hybridization in animals as a machine of speciation amongst completely unrelated animals was absent and/or shoddy at best, providing only the "may" keyword to cover all their ba Correct me if I'm wrong about these assertions as I'm reading it at 4:58 in the morning. I probably missed a good deal of stuff. |

Cup_of_Lifenoodles Fish Guru Posts: 2755 Kudos: 1957 Votes: 30 Registered: 09-Sep-2004 | Allow me to state this more clearly; in higher organisms, natural hybridization, while undoubtedly in existence, is not a defining motive for speciation in ANY species of animal, as far as I'm concerned. Even species that hybridize with some frequency, the most prominent being costal birds, do not display any new species as a direct result of interspecial mating, not to mention that even when dealing with widespread hybrization, which seems to be more or less commonplace only in several insect genera, hybrid offpring could only concievably speciate into a distinct population of new species were they given some degree of reproductive isolation/ environmental alteration. |
