My Alma mater on CBC news! Plant matter in fish diets

My thesis adviser and my agricultural ecosystems professor explaining the rationale for camolina inclusion in salmonid diets. In my nutrition class, we had looked at camlina, as well as some canola meals as partial and full replacements for fish meal and fish oil. You can see rainbow trout and striped bass in the video.

Way to go NSAC!

They've been feeding trout in Sk without any oils or proteins from the aquatic food chain for years. Out of all the bait I've tried. Nothing beats the all plant based pellets. They go nuts for it.

I hope they look at the EPA/DHA ratio. That's an important marketing feature.

Farming carnivorous fish isn't sustainable and turning carnivores into herbivores is laughable.

In the end it'll be Tilapia, Carp and Catfish in ponds-just as it was long, long ago.

They must be doing something right if an angler pulled an escaped from the pens 43.96lb rainbow out of the lake. World record fish.

Oh, I know that farmed salmon and trout have lots of omega-3 fatty acids, I'm just wondering how much vegetable matter can be added before the EPA and DHA benefits to humans from consumption are nulled. The camolina has a good amount of alpha linoleic acid (ranging between about a third, and not quite half of the total fatty acids in camelina), but the conversion de novo to eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) especially is very inefficient. The presence of linoleic acid as well in camelina is problematic because it competes with alpha linoleic acid desaturation enzymes. Which means less synthesis of the EPA and DHA.

That's a lot of jargony biochem, but the end result is the more vegetable matter, the less heart healthy omega 3 fatty acids for the end consumers.

Farming carnivorous fish can be sustainable, but it requires people who don't laugh at what common sense says is laughable. Common sense doesn't mean good sense.

The sun feeds autotrophs, salmon eats what is eating the autotrophs. The nutrition therefore for consumers like salmon is derived from autotrophs. Salmon will never be made fully vegetarian, for the reasons I already discussed with Petros. But salmon don't need to be herbivores to be sustainable.

In the end it'll be Tilapia, Carp and Catfish in ponds-just as it was long, long ago.

Why?

Don't worry about the jargon. If I want to make a living farming I need know what I grow and the optimal conditions to produce the best ntritional product possible.

Agricluture is longer just tossing seed in the ground and hoping for the best. Over the past 20 years the advancements have been mind blowing. Prior to seeding the first thing I do is analyize my soils for TDS, mycology, humic acids and rhizobium content and work my fertilizer ratios accordingly. Try tossing that jargon at an old fart who has been a producer his entire life

Canola is horrid source for fatty acids. I grow it because it is profitable but be damned if you'll get me to consume that **** or any other hydrogenated oil seed.

Wouldn't flax be the best over all choice considering it's doesn't need to be heated thus hydrogenated and is the closest oil seed to fish oils or is it a cost factor like most commercial products?

I've looked into growing camolina but the pulse crop markets are too freaky.

A colleague(Santosh Lall) of my adviser has done some work with flax oil in halibut, and found no impaired growth. They're looking into camelina though because of the poor conditions it will tolerate, reducing the competition for already strained crop lands.

That is why soil is different than dirt. If your soil is maintained properly you can grow anything and have excellent yields. It is a living thing. I'm extremely lucky to have to the land I do. It's some of the best Chernozem on the planet.


Camelina is cheap in comparison to flax and canola and not suitable for human consumption or for aniimal feeds. It's best for bio-fuels. The yields aren't that great either.

Hemp seed hands down is the best oil and protein combination for human and animal consumption but again price is a factor. It's not cheap either.

So what's the point? We've been raising rainbow trout in prairie mud-holes to stop the farmers from filling them in for decades.

The farmers thought it was bonus their kids could fish and bring home dinner.

We never told them it was a deal between us and Ducks Unlimited to make sure there would be prairie water-holes.

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

I apologize for stating this point Tonington, for you are of brainiac.


I am so not going to tell you the details, but it's going to boil down to the good bullies able to protect the good thinkers. We give them beautiful places to have homes and raise a family, and they beat the tar out of evil bullies

So, uhm....who are the "we" above? The DFO?

No, seriously, I'm curious who the "we" are that're repetitively mentioned in the post above.
Are "we" Ducks Unlimited?

But the elephant is needed to protect the wizard that gives us our psychedelic medicine... C'mon... Everyone knows that.

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