Protein content of brine shrimp - Artemia

[Richard Sexton]

I'm surprised to read the protein content of brine shrimp
is as high as it is - 6% dry, 60% live.

But still, 6% protein in a dry food is pretty low.

It also seems to be greatly influenced by diet:

" The highest level of protein of artemia fed on soya
powder diet is 66.88 percentage and the highest level
of fat belong to artemia fed on wheat bran diet is %12.6
so artemia fed on artificid diet has the highes nuturitionl value
of protein and fat in-acordance with harrested samples form
naturad biotops but, there is nat any considerable diffrence
in protein between the artemia fed on various diest.and
also the growth rate of artemia fed on arteficial diets
is more than the natural samples;rate. the result of
this experiment has come in following table"

the 6% isn't dry, that is the content of the frozen package with water
making up a huge portion of that. That is why it seems so low, they have to
rate it as packaged. Dry it is 60% or higher, the same as an adult shrimp
out of the water. So indeed it is good ;o)

Good but not great. Maybe it's the types of proteins or something. If
you want to conditioj fish for breeding you use black worms. Jim
robinson did a small study of this with dozens of pairs of
Aplocheilus linetus and a variety of live foods. Blackworms
won and not by a small margin.

I'm not dissing brine shrimp, they're good. But I still believe
what's in their gut is the significant source of the nutrtiion
as the paper I posted a reference to shows.

So if you have day old BS at the store they may be, as Elains says
"like potato chips". Certainly there's an obvious visible difference
in fresh-that-morning live brine than day old stuff. And the
frozenones have never impressed me, it seems it's like dumping
shrimp soup in yout tanks. Fur and shrimp juice.

It may be 6% protein, but that dosn't do you any good if half
of it has been squeeezed out of the shrimp and is just huice
now. Fish can't eat it and it just fouls your tank.

I thought the paper you posted reached the opposite conclusion? How big
do you think the "guts" of brine shrimp is? How much volume of food can
they hold, compared with their overall volume...

No conclusions about gut loading can be made from this study, if all
that's available is posted in that link. The shrimp would have to be
analyzed both fasted and unfasted to distinguish between differences in
body composition and gut loading.

Hehe, three different conclusions from three different people.

This makes sense, and is also a great reason to use brine shrimp as
fish food. If thawed in a paper towel, much of the waste water is
soaked into the paper. The mushy shrimp are still soaked in the
nutrient laden juices. Now, given the shrimp are not "power protien
pills" and contain a high amount of carapace material, more can be
feed on a per fish basis. This makes the fish extremely happy! They
get to pig out but they're not being overfed. And since fish food
does not contain nitrate, the extra amount of shrimp is not
detrimental to the nitrate load in the tank.

They said protein content ranged from 12 to 66% depending on what
they fed them. Did you read it?

did you read it?? nowhere did they say 12% protein. the lowest was 52%
protein. The 12% mentioned was the highest fat content, which you should
know if YOU read it..

depending on what they were fed, the protein ranged from 52.25% - 66.84%,
the fat content ranged from 4.93% - 12.26%

Well one of us is an idiot and I just founf out it's me. The 12% was
fat. Sorry...

Not an idiot at all, anyone can make a mistake like that one. Not
everyone would have the courage to admit it and apologize. :)
Heck, I learned a lot about artemia during this discussion, so thank you!

So have I - like it's a perfectly viable source of roughage, nutrient and
protein, and when fed along with a balanced diet should enhance the eating
for fish. I also have come to the conclusion from the goings on over them
that they are sort of like frozen bloodworms - they aren't the whole diet -
just a part of it.

I think I'd be a little bored if all I ate every meal was shrimp ;)
