Capturing Methane to Turn It into Fish Feed
As the world consumption of seafood continues to grow, farm-raised fish will likely be a leading source. Usually fish farms use smaller fish like anchovies and mackerel to feed their crop, but a new source of food is starting to be used- methane. The process involves feeding methane to certain bacteria—called methanotrophs—that grow into a protein-rich biomass. It can be used as fish feed and as a substitute.
