Alltech conducted a survey of over 26,000 feed mills of all types worldwide. The survey included mills that create feed for all types of livestock animals from poultry and pigs to beef and seafood and the results reflect a huge increase in aquaculture feed production over the past two years. In 2012 there was a 55% worldwide growth in aquaculture over 2011 based on the amount of feed being produced and provided to the industry. China is listed as the top seafood-specific feed producer with 191 million tons produced in over 10,000 feed mills. Overall combined output from the BRIC nations of Brazil, Russia, India and China increased by 26 million tons.
