DNA was extracted from almost 500 salmon samples! This includes all the salmon collected in 2011 plus others archived in the freezer from prior years. Next steps are to 1) select pieces of DNA; 2) mark them with a fluorescent tag; 3) make tonnes of copies of those special pieces; and 4) send them through a machine that finds those tags and takes pictures of how long the pieces are. Then we can compare these special pieces of DNA to figure out relationships between the salmon!
