A number of scientific studies indicate that warming waters are affecting fish populations globally-and often in unpredictable ways. This finding is significant for fisheries management because as fish populations shift, whole ecosystems are changed.
“It's an immensely complicated situation. You have climate change overlaying everything, and it seems to be changing the way everything works, which means we have a lot of problems. It's getting harder and harder to assess the stocks, to model them and understand their dynamics and predict what's going to happen. Because those models are based on years and years of experience reading fish stocks and studying them, they have been tested over a long time and they rely on a certain set of assumptions and conditions that now seem to be rapidly changing. Tools that have been fairly well established and worked well in the past just don't seem to be working as well anymore."
