There are six species of native Pacific salmon, and although they look similar to their Atlantic cousins there are significant differences. Atlantic salmon are more docile and have a longer history of domestication, making them better adapted to a farm setting. Atlantic salmon have high survival rates, convert food to body weight very efficiently, and produce high quality products with very little processing waste. Several BC farms do continue to raise Pacific species, and over time these stocks are becoming better adapted to the farm setting. However, it is doubtful that Pacific salmon will ever completely catch up to the performance of the naturally docile and efficient Atlantic salmon.
