Hi Jim & All, Oct 24, 2012
I confess to knowing almost nothing about seals or marine fisheries =
but it seems obvious that too many hungry fish-eating seals and too few =
mostly small fish is a prescription for non-recovery of stocks. So two =
thoughts occur to me.
First, the onus is on those who oppose the cull to advance a more =
promising idea for recovery of Cod in the cull area; wait and it will =
happen has worn thin after two decades.
Second, a cull provides an opportunity to learn something about =
Seal/Cod dynamics by examination of fresh stomach contents and thorough =
documentation of same; say sampled at random within each of four regions =
over each of four years and throughout the culling season.
Yt, Dave Webster, Kentville

Also three cheers for Jeff Hutchings of Dalhousie Univ. Biology for =

ecosystems are complex, involving many components of food webs etc., so =
the outcome of a cull is unpredictable and will not be measurable in any =

"fertilizing the ocean" on the West Coast off the Queen Charlotte =

phytoplankton to both help wild salmon and absorb some of our massive =
amounts of atmospheric carbon dioxide. See last Saturday's "Quirks and =

geo-engineering or ocean fertilization.
On the radio today, Jeff H. pessimistically guessed that there was a =
good chance that the Canadian Senate will allow this proposed cull of =
grey seals to go ahead. Perhaps their decision has already been =
announced?
Cheers? from Jim in Wolfville.
