In a previous entry, we've highlighted a research on a novel process to concentrate the protein in standard field barley for use as an alternative to fishmeal as a protein source in commercial fish feeds.

I've received a couple of emails inquiring whether this product is already available in the market. No, I believe they are still far from getting sold off Discount Pet Supplies shops. The researchers have been able to formulate trout feeds with varying levels of barley protein concentrate, and in feeding trials, have replaced both fishmeal and soy protein concentrate, and have applied for a patent on the new production method. However, there is no commercial production in place as of yet.
