Millions of salmon did not show up this fall in the rivers of Canada – The cause is obvious to see?

I wrote an article the other day on the salmon HOT in Canada. No one seems to know why the red salmon do not appear as usual this fall.

However, the information they gave me after I wrote this article referred to above, provides otherwise, and perhaps should be considered a cause of this absence.

First a little history for you who did not read my previous article.

Millions of sockeye salmon called Sockeye has disappeared from their journey through the Fraser River this year. The river is located in the province of British Columbia.

State Department of fisheries around 6 to 10 million of this kind was expected on his journey in the Fraser River this month. A survey carried out shows that only about 600,000 sockeye have taken the trip this year. This vanishing act will have enormous consequences for the fishing industry.

Local fishermen said that the situation is fit and a catastrophe, and even said it critical. CBC considers this to be the worst year in history for the Pacific salmon fishery.

Speculations about this disappearance is has done since the salmon has suffered from the warm waters of the sea, food shortages, increasing the number of predators, salmon lice from some of the local fishermen, farms in the Strait of Georgia.

Another possibility is that the fish are late this year and enter at a later stage. Biologists do not believe this is a plausible reason at all.

The sockeye salmon spend one to four years in the Pacific before migrating back to freshwater to spawn and die. This happens fairly regularly in late summer time. No one has adequate knowledge of the fish that spend their time in the ocean. This is rather surprising, scientists at this time is not aware of what the sockeye salmon spend time on that its not in the rivers of Canada.

Because of this situation, Canadian authorities have canceled the season for catching sockeye this year. Only the Indians will be allowed to do fishing for their own consumption only.

The sockeye count has dropped almost 90 percent in the last twelve years in most lakes in Canada.

The three other species of salmon migration through the rivers of Canada during the summer and fall does not seem to be affected by the same amount of decrease as the sockeye salmon has.

So what makes us draw some conclutions why Sockeye salmon streams does not appear in Canada this year?

In January 2007 the scientists gave a warning to the British authorities of Colombia that sea lice could be the cause of the decrease in the number of salmon in Canadian rivers and lakes.
For the first time in Canada, scientists have used data from the world's largest aquaculture company that there is a connection between sea lice on Atlantic salmon fish farms in British Columbia and infection rates rise in wild salmon migrating nearby.

This alert was published in the Toronto Globe and Mail in 2007. Therefore we can say that the solution to the absence of this delicate fish was found Even in those days, and the cause was infected fish was also identified.

Then in February 2008, the Vancouver Sun published a study of a group funded by the Government switches sides on risks of fish farms.
Pacific Salmon Forum, within the agreed sea lice are killing the salmon. In a blow to the industry of salmon farming in British Columbia's government-funded research group says it accepts a recent scientific study that warns of mass extinctions of wild pink salmon in the Central Coast because of salmon farming.
Uncirculated a "statement" obtained by The Vancouver Sun, Pacific Salmon Forum acknowledged that sea lice infestations contributed to the decline in pink salmon populations in the archipelago Broughton from 2001-2005 – as noted in a recent article published in Science, a leading international research journal.
The article written by Martin Krkosek, co-researcher Alexandra Morton and others, drew international attention. He warned that wild pink salmon could extinct within four years in the BC central coast due to sea lice infestations arising from salmon farms in the area.
In 2007, a committee of the legislature provincial study fish farming also recommended the switch on the sea pens industry open-closed containment net pens to prevent lice infestations on farms spread to wild fish migrating in the vicinity.
Both recommendations have been ignored by the province.

You can say, the signs were there, and the causes were outlined, but no action was taken. Who is to blame in this case, the authorities not to neglect monitoring and control regulation to prevent a disaster on the coast of Canada. It is therefore longer a mystery why the salmon did not appear as expected (by some). It is human interference with its effects on the environment.

The human contribution to global warming and pollution establishing parameters to see how our wildlife and the response accordingly.

There is no excuse for ignoring more has to be a change human behavior before it is too late. We already have too many signs in our food chain we have to clean up our act and the environment become more interested in making the economics of a project or industry. The industry should be responsible for paying the cost of your activity on the environment and the consumer has to accept the price that comes along with it. But I guess this will be too much to ask for – at least today.
