Got a mesg with some good info to share.
"Commercially made fish fertilizer is made from scraps to include flesh scraps, guts, heads, small bones and skins. The fish guts are steamed so as to make the scraps break up easily. The mash is put in a press. The liquid is fish oil and fish liquid. The solids are made into animal feed. The oil is seperated and further refined to make fish oil, The remaining liquid is concentrated by cooking of most of the water. Phosphoric acid is ued to lower the pH. Typically you end up with about 5% nitrogen, 2% phosphorus and 2% potassium. Salt warer fish produce stronger fertilizer than fresh water fish. oldaaer"
Wow,this really puts it in to perspective and kinda fills in some of the missing gaps of information ive wondered about.So there are some steps to further refining on a commercial level of which I cant and dont want to do.Now that I know this,what do I have down stairs lolz and is it a useable product.Ive noticed that it is still decomposing because I have to let the gas out every few days still where as if you go buy a jug of fish emulsion of the shelf it does not so this.I wonder how long this will occur for.It is settling though inside the gallon jug im using and you can clearly see the oil at the bottom which is minute to the lighter frothy stuff on top.
Im prolly gunna let it age a while and let it decompose more in its jug until spring time when I can start using it outside in my garden where I can do a side by side.
