Pond Boss Forums MANAGING AN EXISTING POND Feeding Fish Food Primer

As far as protein it all depends on the amino acid profile.

For example shrimp protein is 70% digestible.

----------------------------------------------------------

This is one advantage of the forage pond strategy utilizing tilapia and freshwater prawns. They not only help each other grow -- TP don't eat the shrimp, while the shrimp do eat TP waste -- but the shrimp are dumb, slow moving, and highly digestible. They'll be eaten first, most of the TP later when the water cools and they get very slulgish.

Esshup quote from PB presentation: "ideal protein.’’ The ideal protein concept is based on the premise that if the amino acid profile of the feed mimics the whole-body amino acid profile of the animal being fed, protein utilization and growth should be maximized."

Why the people in Fiji were healthier back before cannabalism was outlawed (Formally Cannibal Islands).

More seriously (slightly), so a herbivore has the same requirements as a fish eater? Or is that just one of those premise that sounded so logical and good everyone figured it had to be true? What if the premise is wrong?

Fish Food says in response to feather meal in fish food:
"Good fertilizer ... Would you want to eat a fish fed this stuff?"

I'm not convinced that something being eaten by another animal that we find repulsive to eat should be criteria for rejecting eating that animal (or feeding that food). When I was a kid we always ran a few head of hogs behind the cows to eat the corn the cows "passed through". Poultry manure can be fed as part of a balanced feed in a cattle feeding ration. Yet the hogs and cattle tasted fine even though they ate feces. And look at lobster and shrimp. They are the "cockroaches of the sea" (eating goodness knows what off the sea floor) and people lick their chops for them (not me, by the way. My motto is "save a shrimp, kill a cow".

A little research revealed the following:

Herbivore - A raw 100g tilapia filet contains 20% protein 2% fat w/ a 130 amino acid score

Omnivore - A raw 100g Channel Catfish filet contains 16% protein 8% fat w/ a 148 amino acid score

http://nutritiondata.self.com/facts/finfish-and-shellfish-products/4256/2

Carnivore - A raw 100g Bass filet contains 19% protein 4% fat w/ a 148 amino acid score

http://nutritiondata.self.com/facts/finfish-and-shellfish-products/4029/2

I can find nothing that shows that fish requiring higher protein diets themselves have more protein. The herbivore had more protein with a lower amino acid score. Go figure??

In my mind at least Carnivores require around 40% protein in their diet, Omnivores around 35% and Herbivores over 30%.

My best guess is the carnivores have to replenish more muscle mass and tissue from their hunting activities and therefore need more protein to grow. Plants don't run away!

It all depends on amino acids present disgusting or not.

From what I have noticed all part meals are not equal. For example the protein digestibility of internal organs is much better than say chicken feet.

I like "surf and turf"
