Purely a speculative answer: A fish must be about 80% water, so about 5lb of fish to make a pound of fishmeal.
Trout pellets contain about 40% fishmeal - What with wastage etc - I'd guess at 3lb.

Am I close??

How many Angler's think that halibut pellets are made from halibut and that salmon pellets are made from salmon?
Doh, everyone knows halibut pellets are made from halibut, don't they?

I did see that somewhere and its some ridiculously huge amount of fish meal is needed to make a pellet.

Not sure if anyone still does it but there was a company in the past that would make a pellet out of any base mix you sent them.

and a more scarier question...
How many pounds of wild fish does it take to produce one pound of farmed salmon?

Well........ Atlantic salmon have a pretty amazing food conversion rate of about 1.2-1.4 to 1. Then working on the basis my figure for the amount of fish needed to make a pound of pellets is correct - 3lb.

3lb x 1.4 = 4.2lb

But I think the answer will be heavily influenced by whoever conducted the survey and what they want it to say.

Next you'll be claiming trout and salmon pellets aren't made from trout and salmon?

Sixteen pounds, if they are pellet fed - and they are.

I have no idea. I simply believed the figure which was given to me by a fisheries scientist with probably more letters after his name than I can count.

Well of course they are... and only the best Salmon & trout filets at that !

Just like the Game anglers anglers who fish for them, you cant expect an upper class fish like a salmon to eat any old rubbish can you.

It goes back to the remark I made a couple of posts ago: "I think the answer will be heavily influenced by whoever conducted the survey and what they want it to say."

This wasn't just some geezer in a pub - it was arguably one of the country's leading fishery scientists. Where's Bad One when you need him? Can you back this up?
