Cheryl, I think wakame can only be consumed after 1, at the very least. I believe it's quite difficult to digest. I think I've seen rainbow trout at NTUC Finest.
Jerejoy, if you're making chicken stock then use a huge pot, throw in the entire chicken, boil, skim the scum (ie the dirty stuff that surfaces once it starts boiling vigourously) then continue to simmer for 2-3 hours. Same if using pork ribs. If it's veg stock, then use carrots, celery, onions, potatoes, parsnip, tomatoes and simmer for 1.5 hours or so. I don't measure out the water so can't give you exact measurements. You roughly guess la, don't put too much to start off with, add only if need to, otherwise stock becomes too diluted.
