Some of the more entertaining post are provided whilst under the influence.. All you really need is the ability to speak drunkenese.
Good point.

I'll say then, that rule should be that the alcohol produced posts should be allocated to a new section.

Perhaps "From the bottom of the bottle", would be an appropriate title.

Ok I missed most of the science you are talking about but I think this is about better health and nutrition without GMOs. Right?

Again... I'm missing the point, and I apologize for missing it, but what's your point?

Well technically my point is that the school I graduated from, and my adviser, and another of my professors was on television. I think it's always a good thing for the public to learn more about agriculture.

Their point, is that aquaculture is growing, while bait fish harvesting is not, it's stable. Replacing a percentage of of the fish meal and fish oil in aquaculture feeds with terrestrial crops that are not competing with food crops reduces the demand for wild fish stocks that are under heavy pressure, and makes the agriculture system as a whole more efficient.

Sounds awesome. If only you invented a process that made the farm variety taste like the wild.

NOt so much better health and nutrition as it is about moving towards more sustainable practices. Other examples of sustainable practices include engineering closed containment systems, such as the system Agrimarine has developed.

We could maybe apply it to cows pigs and chickens too!

It won't make them taste as bad as farmed fish will it?

No, make them taste more like their wild cousins...if we found a way to make farmed fish taste like wild fish. Not likely to happen. The proteins they are eating aren't the same.

But actually, some farmed fish taste the same. If you raise fish in an extensive system, they would be deriving their nutrition from the available food web in the system only.

If you have about 20 minutes to spare, watch this TED talk about farmed fish.

The Prairie trout are very tasty. If you ever want to come and do some real hunting and fishing in SK my door is open to you.

I'm sure they are. It's rare to catch a brookie anymore in SW Nova Scotia, damned chain pickerel and small mouth bass have displaced them. I'll let you know if I'm ever headed out to Sk.

Some of the West coast ones are quite good depending on species. The springs out in Kyugot Sound taste more like fish than the Atlantics raised here. Same with Orford Bay. Their brood stock was all indigenous. Even some atlantics are good but I think it has to do with how much wild feed they get since some farms are much better placed than others.
