if any radiation from Fukushima is in the water on the Pacific coast? Why are they not even mentioning this as one of the possible causes? I might be way off base thinking that this could all be related, but that was the first thing that came to my mind.

Whatever the reason, it is odd that two separate species are being affected at the same time.

Even considering where these fish migrate afield, there's no credible exposure link.

If I had to hazard a guess, some foundational leg of the food chain might be buckling, due to acidification or something. Probably a nutritional deficiency.

Freaking melting? That just doesn't sound like a nutritional deficiency. And I wouldn't think that salmon and starfish have the same food sources.

Is the ocean too vast? Yes and no. It is too vast, except that currents do keep water from certain areas more concentrated than you would expect from the whole ocean.

I don't know, I'm just thinking out loud here.

A material that starfish bone is made out of. Higher concentrations of CO2 dissolved in the water, lowers the Calcium Carbonate concentration, making creatures that use it expend more energy forming bone or shell. (Starfish have bone-like material)

A couple percentage points shift might impact a species or two quite severely. Stressing them, until they are susceptible to some viral infection or something like that. (Again, I am speculating)


As for the yellow Pink Salmon... I've seen none of this down in WA state, so far this year. That's weird. I wouldn't eat one that looked like that. No way. I can't speculate on if/how the two events might be linked. The salmon thing is super weird.


Edit: I'd be looking REAL close at upstream stuff, from that bay, on up the river. Someone might be dumping something.

Even the experts are speculating at this point, but you are right, looking upstream is a must. However, it seems that the problems with the salmon would have taken a longer time to develop that the time they would be in the river or the bay, since they don't live there and only get there in time to migrate to the spawning areas.

It does make sense that acidification of the water could cause a lot of problems. Yes, I remember when we had to dissect a starfish and how hard it was to cut into it. The endoskeleton was definitely a hard calcium composition, so the inability to obtain enough calcium would be a major issue. Excuse my repetition here though, but melting????? (Sorry, I can't get that out of my mind.)

Not sure about the salmon. They change quick. They don't go red, grow the hump, elongate jaws until they hit fresh water. When they do, they change quick. Meat turns grey, they get kinda nasty. I could see them going yellow, depending on the cause, in a very short span of time.

Plus, the amount of radiation on west coast of North America from Fukushima will be small due to diffusion in the world's largest and deepest ocean.

However, ocean acidification from ocean warming and high CO2 levels is a plausible mechanism for harm in shelled sea animals, which sea stars are part.

But that's not to say this is global warming either. It may be something else entirely. But it most certainly is not Fukushima radiation.

The best thing to do is to not speculate beyond the data and to wait for the science to resolve this, which may take some time.

but I hate that it always takes some much time....all the while the damage is continuing.

But really, speculation serves a purpose, at least for me, in that I have to think. And I learn by having people throw other speculations that are more feasible at me. It is like doing a crossword puzzle---I don't really accomplish anything, but I learn new things.

I am eager to learn new things. It's why I studied physics way back when. But DUers are generally pretty damned smart. I don't dive into threads like this often. But where I can bring some of my ancient and meager education to bear, I will jump in. Hopefully, politely.

Thanks for the response.

The size...meaning that if say a million starfish are melted in a contained sea, the same would be true in #s for the Pacific. Plus, currents in the ocean are like rivers, and the strength of the radiation is much greater in these currents than in areas not much effected by these currents. So, in light of no fish being tested for radiation in the Pacific Northwest and the currents of the Pacific Ocean, and the huge continual release of highly radioactive waters off of Fukishima, I'd suspect radiation. Only science will answer these questions, and unfortunately the concentrations don't appear to be diminishing in the foreseeable future. A start would be to not eat any thing from the Pacific. The longer we wait, the more damage to our environment and our people (and of course any other organisms).

It's called diffusion.

Look it up.

and the tsunami, our ocean is in far far worse trouble than we know.

I have these nightmares of Soylent Green....that is supposed to come from algae in the oceans, but the oceans are dead and the truth is just being kept from people.

Coho were all fine too.

There are several that periodically pop up in west coast salmon populations. Slight increases in water temperature and changes in pH could be giving the bugs the advantage.

with; an invasion. The effects could be cumulative so they did not die right away. Probably most have been poisoned but there are few who have genes to survive it; the ones on the margins between the ranges. These need to be found. It is believed that evolution appears in short spurts, like a die off of almost all of the species with the few remaining to restart the population in a change environmental range or co-community (the ones from the margins that have gone upstream somewhere).

Flamingos are only pink if they eat a certain kind of food/proteins.

Thanks for reading my opinion.
