SVenus: Without knowing what was in the study, I'll pose a few questions
1) Was this a double blind study?   http://rationalwiki.org/wiki/Double_blind
1a) If not, why not?
2) How many years in real life is expected to reach the level of acidity used in the study?
2a) How long was the transition period between normal conditions and these new extreme conditions?  Was this considered an appropriate amount of time to allow for the adjustment of the fish to the new environment?


First off, this is a behavioral ecology/behavioral physiology paper. The paradigm isn't psychology, but instead animal behavior and simple physiological and behavioral responses to stimuli. More physiology, less psychology.

So to answer your questions:

1/1a : In terms of the researchers, probably not. Blind studies are very uncommon in the biological sciences. However, considering the observations were done through a computerized motion tracker, the potential for observer bias is minimized.

As for the participants, while your asking if the experiment was double blind is rigorous (if not curious), please rest assured thatfish do not need be kept unaware of the expected outcome of the experiment. As far as we know, fish do not have expectations in regards to experimental protocols, or at least, they have declined to voice said expectations so far. In case you continue to ask questions along these same lines, the fish were not required to sign off on an informed consent form, they were not compensated for their participation in the study, and their real names were not used in the publication.

2: 0. Conditions approaching experimental conditions (1125 ± 100 μatm) already exist for periods of time, but on average (according to them) about 200 years, but of course dependent on emission scenarios.
2b:7 days. This was considered sufficient to acclimatize.

If you have further questions I can put the paper up for you somewhere. Just ask.
