Wich food seems superior?

Because of your knowledge of chemistry I wanted your opinion of wich food is best?

Also, what are you feeding your fish again?

I'm not qualified to comment much on which foods look better, but I can say that I use various frozen and flake foods from Ocean Nutrition mostly, with occasional use of some frozen mysis.

 

[boxfishpooalot]

Awww, not qualified? Ok, you know your 100% qualified in the lab anyway.

Just out of curiosity, what do you know about fish meal? I think it is far less superior than whole salmon would be(the two most abundant ingredients between the two brands). Correct?

The process of manufacturing fish meal would involve drying it I beleive. Would this cause a degradation of proteins/fats/carbohydrates somehow?

Also, what is ash and is it bad?

How do they preserve the nutritional value of food when they turn it into flake food?

 

[reverendmaynard]

I'm certainly no expert but I do have some thoughts...

I would imagine that the one with the whole fish has to turn that fish into fish meal anyway.

AFAIK, ash is bad (I know it is what causes urinary problems in cats, fwiw), but only one of your foods lists it. I wouldn't take that to mean the others don't have it.

I'm pretty sure they don't preserve the nutritional value very well at all. That's why they add all those vitamins and what not, to replace what is lost through processing. Fish eating whole fish shouldn't need vitamins, IMO. The processing destroys most of the natural vitamins, so they are replaced after processing.

They're probably pretty equal, IMO. Soak in selcon to add more nutrients if you want.

on a related note, what is the lowest phosphate containing food or are they all similar? Do frozen mysis for example contain more than the home-made type of seafood blender stuff such as Borneman's recipe?

Do frozen mysis for example contain more than the home-made type of seafood blender stuff such as Borneman's recipe?

That is hard to answer. Many producers put phosphate salts of various sorts on fresh, frozen and canned seafoods as a preservative. So when you buy them, you may be getting more than you asked for.

Ron Shimek does some food analysis here:

Boxfish,

I think your best bet is variety. Feed them a little bit of different types/brands of food and you can't go wrong. Seems like I remember this topic from some time ago.?
You might also want to try some Omega One. It is all whole fish.

PS: Avoid the Soylent Green.

:lol:

I remember that.

Hmm - there is no phosphates in ron's charts only phospohrous, but in most living creatures I believe that is is mostly in phosphate form - it seems that the formula foods fare pretty well at least by this criteria

 

[Randy Holmes-Farley]

Yes, nearly all phosphorus will be either as organic or inorganic phosphate.
