"Is anyone here a marine biologist?"

I seen one on tee vee!

The recent publication by the University of Washington (UW) in the scientific journal Science was a major breakthrough in understanding the challenges wild-run salmon face.  Every Spring and Fall, millions of Salmon up and down the West Coast voyage from the Pacific back into their native rivers and streams to spawn.  Unfortunately, significant numbers of Coho Salmon never make it to the spawning grounds and instead go belly-up and perish for no apparent reason.  This has puzzled scientists for decades. The cultural and economic impact of this die-off has only worsened with time and could threaten the future of wild Salmon overall. 

The breakthrough at UW was identifying the acutely toxic compound to the Salmon: 6PPD-quinone.  The compound, 6PPD, starts as a tire additive designed to prevent tires from breaking down and aides in meeting federal safety guidelines. These important compounds are known as antidegradants and can protect tires from anything from sunlight to oxygen to extreme temperatures. In the very process of protecting tires from oxidation, 6PPD is transformed into 6PPD-quinone, which was unknowingly toxic to Coho Salmon. As tires wear, the worn rubber is continuously deposited on roadways.  This deposited material invariably makes its way into waterways through runoff from rains. Although rain naturally dilutes the runoff, the 6PPD-quinone was found to be toxic at the low concentrations found within streams and rivers.

 

Can you believe this biologist BS. Who can even confirm that there were any coho salmon in those rivers before runoff from tires entered the river.

That is interesting.  Don't know how you can prevent it unless they stop adding that chemical to tires or find a way to filter it out of the runoff.  Coho are great fish, they are prolific, good to eat and a great fish to catch sports fishing.

I am guessing this is more of a dig at the biologist BS remarks going around. 

  I'm going to get a dig of my own in here. The remark of the hellbenders eating fish eggs is a bit selfish IMO. The fishermen catching smallmouth off there beds and hooking throats deep or ripping gills kill more than our giant salamander that was here before us. Ok my BS has been said. I feel better this morning. Flame away.

I just thinks it's kind of a funny spin on saying they at eat eggs. Last time I read something. It seemed pretty much anything that lives in the water wants a crack at those eggs. Just saying.

Trout love to eat Salmon eggs and Trout eggs and native sucker eggs.
