[Coral-List] Lionfish in the news

It just seems to me that it has become fashionable to use the lionfish
invasion as a scapegoat for the decline of many native fish communities.
This takes the focus off of the multiple human stressors and the
uncomfortable need to assess and manage human impacts. For example, from
everything that I've read it appears that there is a more direct and
preexistent correlation between human population density and declines in
grouper, snapper and other predatory fish populations. Although there may be
good reason to target lionfish, it may prove more important to control
ourselves if we are to preserve coral reefs and other marine ecosystems.

I was just trying to alert people to this new study, since it seems
many people are interested in lionfish.
Yes, my understanding is that lionfish were reduced only in very small
areas in this study. It sounded to me like they were suggesting that if
most but not all lionfish were removed from small areas, that the recovery
of native fish species might be able to produce the eggs to seed other areas
and help them out. I don't know if that would work. But I haven't read the
original article yet. I'm not vouching for this article, just thought
people would be interested. I think the article should be scrutinized like

I believe the article raises more questions than it answers.
The most obvious issue may be related to the size of the reef areas involved
in the study:
"A typical reef site, which is about a third the size of a basketball court"
. . ONE THIRD THE SIZE OF A BASKETBALL COURT?
How does a study carried out on such infinitesimal areas of reef apply to
the issue as a whole? It is one thing to control lionfish on these small
parcels, but how do you apply the same techniques effectively to vast areas
of reefs many of which are at depths below which divers can even access?
The article also implies that the main reason for grouper and snapper
declines is lionfish . . . wonder how they came to that conclusion?
