There's a small uproar in the environmental community going on about the possible farming of engineered salmon. The engineered salmon grow up faster and have more muscle tissue. The fear is that if the salmon escape and breed the natural salmon will be out-competed. This could have many unpredictable
repercussions. I propose that the growing of engineered fish be allowed. BUT, engineered fish should be given an evolutionary disadvantage that will harm them should they escape to the wild. It's possible to make animals glow using a certain gene from jellyfish. You've probably heard of the process, it's been used on everything from rabbits to monkeys. I say make the GM fish glow in the dark. That way, if they escape, their offspring will be easy for predators to find and kill. They will not successfully compete with the wild salmon. The gene will not affect the quality of the salmon meat, though as a bonus, the meat will probably glow under a blacklight. That would be a sure-fire way to identify the GM meat for people who choose not to partake of it.

Glowing fish? It would be a hit at the swankier dance clubs...
Electro salmon pate anyone? |
|

It only really glows under a blacklight. You'd need to do a little bit more than I suggested to make it glow -all the time- while its alive but it would still glow a bit regardless. It would also be brightly colored. Actually come to think of it changing the color of the fish's skin so it's not camoflaged might work by itself. |

Well if you believe that you're an id... (just kidding) |
|

sorry. That's just not very consistent with any understanding of Genetics I've ever been presented with. |

Animals that hunt salmon are using blacklight ID techniques now? Holy shit! Who knew? |
|
| |
Actually, yes. Most animals see a completely different range of colors than we do. And even if they don't glow their camoflage will be shot to hell. |

I'm pretty sure I saw something similar in a Schwarzenegger movie. |

We could just farm GM salmon way inland, and only allow the fish to leave the farm after primary processing (freezing, filleting etc). |

Farming salmon often involves profit-motivated pressure to confine a relatively large number of them in a relatively small space. This inevitably makes the transmission of disease easier, and to counteract this many chemicals (e.g. antibiotics) are used. For this reason alone (even ignoring the moral/cruelty dimension) salmon farming should be discouraged. The use of salmon which have been artificially messed with to better meet our needs is an offence against nature and typical of our assessment that we know better than eons of evolutionary progress. No no no!
Salmon bone to you. |
