Hi Paul,
Do you know how much, if any, hatchery stocking of salmon goes on in NB and NS rivers?
All the best,
Lance

Yes Dave - Salmon number on the Miramichi have never been higher
and records go back maybe 50 years. Newfoundland rivers and Quebec Rivers
also. All on the internet but it takes time to dig them out - easier to express opinions
than to get the facts - LOL
The numbers are a function of 2 main factors - the number of fish available to return
and the amount of water in the rivers plus the interaction between the two and variables.
such as the spring tides corresponding to the major returns, rain at that time.
On the Lahave the counter is at Morgan Falls at New Germany. Only the fish that
go up the falls are counted - fish that go up other branchs or stay in the main river
don't make the count so the count at Morgan Falls is a good indicator of the total
return but is not the number of fish entering the river. The counter used to be open to the
public and had a telephone number that gave the up to date count. Perhaps will be
this year also but I haven't visited or called lately.
Counters are kept at many other rivers in Atlantic Canada - all on the www.
This year looks like the counts will be down - not for lack of fish but lack of water.
We definitely need a few good rains - perhaps the farmers should get the hay up soon!
Have a nice spring
Paul

Hi Paul, Jim & All, June 12, 2012
If I understand you correctly Paul, the runs on the NB rivers that empty into the Gulf of SL were unusually high last year. Have I got that straight ? If so then that is very good news. How far back do the records go ?
Drawing on memory, all of the famous Salmon rivers in NB emptied into the Gulf. For many years, every road end along Fundy beaches had a weir and salmon were caught. As weir owners died these weir rights died with them in most cases (some owners fought and managed to have them passed on I think), as I recall, on the assumption that weir catches were impacting salmon runs.
Everything I know about Salmon and aquaculture could be printed on a thumbnail but when I hear people asking to have Salmon farms moved inland to save wild Salmon or the Rockies moved east so Saskatchewan won't be so flat, I have a feeling that my thumbnail counts as an ace.
Building Salmon ponds on land near the coast, maintaining adequate O2 levels, filtering out the waste and composting this waste would be energy intensive, at a time when energy conservation should be a top priority, resources intensive (for e.g. pond linings, pumps, retaining walls, waste water conduits), the land for this would cost a bundle and those who own expensive costal property might not welcome industrial ponds next door and the additional cost might well put another industry out of business. We need jobs, food and tax revenue so solutions have to be realistic.
My 2 cents as they say, rounded up to a nickle now.

Hi Dave
Good points you bring out.
The whole question has brought out people with lots of opinions
but with very little knowledge. But that never stops the Media types - LOL!
The wild salmon population in the Gulf of St Lawrence rivers was at an all time
record as long as records were kept. That was last year. Newfoundland rivers the
same with some exceptions as were European Rivers.
A couple of rivers in Maine had large runs but the Bay of Fundy and Atlantic Coast
rivers were low. All the while the Natives and DOF play their chess game so its
hard to know if the population is going up, down or sideways.
Nova Scotia Rivers have big problems - the Mersey with dams, the Lahave with chain
picheral and so on but instead of trying to solve these problems the media want
to wage war on the Fish Farms - go figure - guess they want something sexy
where they can find a villian. Sure not going to help the fish.
Have a nice day
Paul

Hi Sandy & All, June 11, 2012
The question that nags is: Would salmon have declined to the same extent (or nearly the same) if there had been no aquaculture ?
Public pressure (perhaps misinformed pressure) may force the industry to undergo a modern version of ordeal by water; the original being you are innocent if you sink and drown but if you rise alive to the surface then you are guilty and burned at the stake. So this is not just an academic question.
Drawing on memory, e.g. poor salmon runs in some NB rivers as early as 1950 led to a program to control Mergansers way before farmed salmon (I think). Also salmon runs along the South and Eastern shore have been in decline for 5 decades or more. how can aquaculture have caused this ? Have acid rain and overfishing in the ocean had no effects after all ?
Assuming that sea lice and escaped farmed salmon adversely affect wild stock should not the emphasis be on solving these problems ?
Yt, Dave Webster, Kentville
