Bill,
The Sugihara et al story is a mere hint at what those of us who were
'raised' in the CalCOFI/EasTROPAC La Jolla Fisheries community have
learned under the direct influences of folks like Reuben lasker, Paul
Smith, John hunter, Alan Longhurst - et al - and preached over the
years -
Meanwhile, the imposition of the Magnuson-Stevens Fisheries (Mis)
Management Act simply 'flushed' any such knowledge - and shoveled
equilibrium-based, single species population dynamics BS models
(1950s logic and techniques) into the rapidly recruited 'computer
generation' -
Now 40 some years later - people are starting to speak/write again
about what we knew, and how fisheries ecosystems should be handled -
Most of the NMFS co-authors listed in the paper are folks whom I have
helped keep their eyes on these basic eco-physiological interactions -
I have known and shared common concerns with John Beddington since we
first met back in the late 1970s...
The Following link says a lot - and if you notice - his focus is not
just on fishermen - but More Mouths Needing Fed...

Bob May was also a routine visitor to FAO in Rome - where we (John
caddy, Serge Garcia, Jorge Csirke, and myself) were in complete
agreement about the 'stupidity' of Equilibrium-based population
modeling being hyped by our Boss - John Gulland - <http://
www.mhs.ox.ac.uk/blackboard/may-text.htm>
Jorg, Serge and finished up the Report from our extremely successful
1983 Expert Consultation with the Chapter entitled -Modeling
Fisheries - What was The Question?
<http://www.fao.org/docrep/005/x6849e/X6849E09.htm>
You will find that on all the other subjects in the SIO News Release
are well defined topics that I have been advocating in all my efforts/
writings/workshop Reports - etc - since the mid-1970s. In 1986 - John
Caddy and I co-wrote the first published FAO Tech Report on An
ecological framework for marine fishery investigations
<http://www.fao.org/DOCREP/003/T0019E/T0019E02.htm>
And we both kept the pressure on - John Caddy, Review of “Marine

And we keep on Trying!
The primary issues are all about the necessary but today too often
missing independent surveys of the many species in any ecosystem -
and how they reflect the Environmental variabilities, and stock
status - as in Size-at-Age, Age at First Maturity, Energy Content,
and relative distribution and abundance - ALL reflecting important
inputs to Forecasts of Resource and System States - Thus what might
be removed, where, and when - so that 'responsible' management can be
achieved.
Another example that Jonas still cannot read what others write -
The SIO Story was not just about Big Fish - swordfish were brought up
as a good ongoing example -
As anyone who knows a little about the various species - the LARGE
fish in the swordfish populations are ALL Females - as the males have
a very restricted growth rate - always have - that peaks well below
the length/weights attained by mature females - common on most
billfishes -
The opposite situation exists in the tunas - where - for example -
almost all the true Giant Bluefin are males - suggesting that these
two mobile species groups should be managed differently...
THEN, THERE ARE THE SEMI-INFINITE PUBLICATIONS ON THE EFFECTS OF MANY/
ALL 'STRESSORS' ON GROWTH AND MATURITY OF EXAMPLE SPECIES FROM
BACTERIA TO PRIMATES...
Back to work!
