MPA Benefits - In Numbers

[Sale Peter]

Be careful.  There are lots of papers that show an increase in stock
within the reserve, and many that claim an increase in fishery yield.  But
I do not believe there are any papers that demonstrate convincingly that
an MPA has enhanced yield in the non-protected, fished area around it to
an extent that exceeds the potential loss to the fishery by creating the
reserve, and removing that (reserve) area from the former fishing grounds.

Reserves PROBABLY enhance fisheries, but the data are not yet in.  Garry
Russ may be able to amplify this (or correct it).
