After reading the article by Les Blumenthal, McClatchy Newspapers – Sun Mar 7, 2010 – “Growing low-oxygen zones in oceans worry scientist”. It stated: ‘In some spots off Washington state and Oregon, the almost complete absence of oxygen has left piles of Dungeness crab carcasses littering the ocean floor, killed off 25-year-old sea stars, crippled colonies of sea anemones and produced mats of potentially noxious bacteria that thrive in such conditions.’
What was interesting was the bit about: ‘Most fish can swim out of danger. Some species, however, such as Chinook salmon, may have to start swimming at shallower depths than they’re used to. Whether the low oxygen zones will change salmon migration routes is unclear.’
The good news is you may not have to troll the lower depths, which means less time reeling them in. What do you think?
