To Smartymarkety:

This ratio claimed by the International Fishmeal & Fish
Oil Organsiation makes their fishmeal and fish oil industry sound less
environmentally egregious than is generally reported by virtually all
independent researchers. In his recently published book, “The Ocean of Life”
Dr. Callum Roberts claims a ratio of five pounds of wild caught fish to produce
one pound of farmed salmon. He also makes the claim, “…aquaculture will likely
swallow all the world’s fishmeal by 2050.”

As well, the on International Fishmeal & Fish Oil
website’s section on “Marine Resources and Sustainability” (http://www.iffo.net/default.asp?contentID=718)
page, you have a graph showing where most of your forage fish come from. It
seems that anchovies from Peru and Jack Mackerel from Chile are your top
suppliers. Please refer to this Investigative Report by a consortium of
journalist titled, “Free-For-all decimates fish stocks in the southern Pacific”
http://www.iwatchnews.org/node/7900/)
that details how the jack mackerel stocks in Peru and Chile declined 63% in
five years due to the fish meal and fish oil industry.

Kirk calls his tours “Sea Foraging” as I think that leaves them open to more possibilities, like gathering seaweed and mussels, as well as catching fish.

To update a point contained within the Lenfest Forage Fish Task Force report referred to above, please note that the conversion rate from whole wild feed fish to whole farmed salmon as substantiated by IFFO (the International Fishmeal & Fish Oil Organsiation), known as the FIFO – fish in: fish out for salmon
was 1.5:1 in 2010 and falling in 2012. Therefore 1.5 kilos of forage fish are used to produce each kilo of farmed salmon. The
calculations behind these ratios are detailed in the papers referenced below and they also explain why the IFFO calculated FIFO ratios differ from ratios for salmon calculated by Authors Tacon & Metain (2008) and Naylor et al (2009).
