Part of this is because of the changes in catch laws. For example. Many of the fish in the oldest photos are Goliath Grouper. Nearly 30 years ago harvesting Goliath Grouper was banned. So it makes sense that you would see far fewer pictures of a fish you are no longer allowed to catch and keep.

1965 (mentioned in the article as being the start of a period in which pictures show smaller fish) is 50+ years ago however

  I'm not sure that disagrees with the point. There was a species of fish that was particularly large that was caught. It was identified that we were damaging that species, so we banned catching it. It makes sense that part of the evidence for banning, was that we were finding less of them, especially at size. That is, the point is that this metric was largely driven by that fish species.
