    Hi
    .
    I want to make diy frozen fish food, and need some of the experienced chef's advice!
    .
    I wanted to buy frozen food like hake, mussel, calamari and prawn tails today, but saw that it contains "20% glazing". Don't know what the glazing is, but according to the label, it keeps moisture in... Is this safe to use? Should I just wash it properly with RO water?
    .
    There are also shrimp tails, but it is cooked, I guess I should leave that out, right?

    Hi Louis - yes. Just "Wash" the frozen marine mix/hake/etc with RO water (to get the glazing off), then I usually use tank water to mix/dilute my frozen food during blending.... :)

    Thanks Jacques, will do that.
    .
    What about the shrimp, can I use it?
    I have also read that some people use garlic, vitamin C, Centrum tabs, Spirulina, etc. Any advice, is it safe to use, and where can I get it?

    Yes, yes and yes. It won't cause any harm. The fish will adapt to the shrimp in the long run. And you CAN indeed add garlic, Vitamin C, etc..... it won't do any harm, as far as I know.

    EVEN though these don't "naturally" occur in the sea in the same form as you are feeding it - neither does keeping fish in a small glass box seem "natural'....

    All these other "additives" that you are talking about, at least could possibly make the fish healthier.....

    Isn't glazing just another word for water?

    Dean - I do think that the glazing does contain some additives, though.... not only pure water.

    I have no idea, the packaging only said: "only 20% glazing". I assumed that it is something artificial.

    Best binder for your own food is sodium alginate, and for pure Vitamin-C i use Balanced C

    Thanks Singularity. Where can I buy these two products? Pharmacy?

    How much do you use of each product?

    I read somewhere that "binders" could end up on your sand, and then bind that together. .. is this save to use, or is it safer to leave the binder?

    Sodium alginate is the best binder for marine food, this just helps that it doesnt go all over the place when you feed, just do some googling about it, i dont think you will have that problem with sodium alginate. The Vit-C you should be able to get from a good pharmacy, the sodium alginate you will have to order from a chemicals suplier, its relatively cheap. I dont really want to say how much of what, i just follow some of the basic recipes that you find on the net and add a little more or less. I also use centrum tabs, spirulina tabs and fresh garlic. If you can find high quality whole herring meal it will also be good for protein boost, but it has to be high quality whole herring meal.

    Oh I have always been put off by the "20% glazing" especially because it all comes from China. Have been from fishmonger to fishmonger looking for fresh, unprocessed fish, but if you guys use it, then I will give it a try.

    It does work, colbar....... BUT, I would indeed wash off the "glazing" with some RO water first!

    Jacquesb, anything that is frozen (like the cubes, or home-made food) I feel should always be rinsed to remove phosphates. I let it thaw in RO water and then just give a rinse with more RO water.

    according to matt wittenrich( marine biologist who has successfully bred over 90 species including mandarins) you can use gelatine as per instructions to mix in with your food mix , set it in thin slabs and chop a little up each time you feed. this prevents food dispersion and fish can enjoy their food. ps use ro to make up gelatine mixture and cool slightly before mixing finely chopped up food in it.. agar agar can apparently also be used(gelatine made from seaweed)

    Sorry guys ... anyone feeding their livestock lobster/crayfish? BTW for people like me what is the difference between lobster and crayfish .... oh what about crab meat as food and are your cleaning the hard outer skeletons of these foods or crushing them with meaty parts?

    lobster is like a crayfish with two large pinchers(not found in sa) and a crayfish and a rock lobster are one and the same.
    a little of the shell is alright as fish need the chitin but one needs to be carefull cos the high cholestrol in crayfish will result in swollen liver if fed to fish too regularly.
