There are OOO's of theories of what is happening to all the Salmon on the Coast... Me, I have live all my life on Vancouver Island. In the 60's...70's..& 80s - our family enjoyed the bounty of the sea...Salmon, cod, halibut (other rock fish), Prawn, crab...and all typs of shell fish.... Yup...hard to believe them days are gone.
If I wanted a fresh salmon...30 min I was on the water and in 10-30 min, we had a fresh fish... I remember the days when hugh kelp harvesting barges stripped the coast line of the 100 metre wide kelp bed along the shore line. Herring 2 pounds.. now we see 1-2 ft thick of roe washed up on the beaches... YUP... When is that the herring smolts imerge...hmm right around the time the year-ling salmon return to the ocean.... then there is the shrimp... We drag for OOOs of tons in the winter and early spring...yup right around the time they spawn.... So, when do the shrimp spawn hatch...right around the time (or just before the herring hatch AND the returning salmon... Scientists and biologist will tell a very different story I am sure. but my guess is that MANY SPEICIES of fish feed on both shrimp and herring... Oh and Whales and Seal / Sealions... birds... Oh and the cod or bottom fish...
Needle fish, smelt, hoolegins....it was always fun to catch a few in the light of the moon...Yup...hard to believe them days are gone. If we destroy the habitat, then fish tonnes of herring for row...we take a chuck out of that eco-system for sustaining the health and popupation of Salmon...whether they are yearling Juveniles retuning to the ocean or mature stock.
I grew up on near a local river... Salmon, trout, steelhead... its true, one could walk on the fish there were so many... Logging, mining, farming, hydro-lines, golf course ALL USE Hurbicide sprays, un-due care with roads and hwy building... Sure there are a few rivers with a few fish coming to spawn...but what happened to all the salmon? Trees on the hills slow snow melt I think... Now with a quick melting snow pack, rivers and streams are blown out by the hugh rush of spring freshet snow melt. I am not sure what considerations are made ...province say...don't log within 50 feet of a stream
Everyone seems have some idea for the disapearance of the salmon...but know one seems to have a solution... My 82 yr old father says its the sprays used which killed the streams; Agent Orange has been used to year...now they call it Hurbicide. Science says its Global Warming...and we need to do more studies...they have been stuying for 50yrs.... DFO thinks we are over fishing the species and need more regualtion and yet there are fewer fisherman today than ever. Some public voices says its the fish farms with all their polutants and deceases. Its like everyone is fighting for a solution. We know we are adding more and more pollutants to our lands, rivers & streams, (water systems), oceans, air... Last year in one afternoon, in the boat I was on, we caught around 30 salmon...and retained NONE.. Half those fish will die and some were dead.
Ahhhh, I could go on and on...
So, what has happened in the last 25-30 years.
