Why has the salmon fishery declined in BC over the past 30 years?

IN GB, seabirds and seals have proliferated, leading to a decline in fish stocks salmon and other speices. Seabirs and seals are protected species so the much needed seabird/seal cull is not allowed. Politicians blame it on 'overfishing'.

The Japanese are more sensible than the British and the rest of the EU, they control the seabird/ seal numbers and there is never any problem with lower fish stocks, even though many of the 150 million plus Japanese eat a near pescatarian diet.

Salmon spawn in rivers - they spawn in the same rivers they were born in, in fact. So they swim upstream to the place they were born to spawn (spawn=make babies in their own way). The biggest problem is that many of them can no longer get to that place because of low water, dams, obstructions - habitat degradation, as the other said.

Here in Northern California people are building ladders, tunnels, bypasses around dams and whatever they can to help the salmon get back upstream like they are supposed to.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
