Clams filter the water and check whether the water is polluted or clean

Re: Clams filter the water and check whether the water is polluted or clean
#42Maybe they could have alerted about the lead contaminated water in Flint Michigan? A disaster that will affect the next generation. Lead Lowers IQ's in Children and increase crime rate in adults. BTW, the invasive Zebra mussels have done a great job clearing up the Great Lakes. At times the water is so clear on a sunny day in the summer it can look tropical blue.
The water being crystal clear looks cool, but it's an ecological disaster for larger fish in the food chain that depend on the turbidity of the water for ambushing smaller fish.
Crystal clear water also means that there is a scarcity of nutrients, otherwise algae would grow.
But this isn't necessarily a desaster, not all lakes are equal in their conditions for various species. This might just be what the lakes looked like for the longest time.
Btw., there are large fish hunting smaller ones in clear water. Most extreme example are sharks.

#43For those who love eating clams and just like myself wonder how safe it is to eat clams, while they filter huge amount of water -- yes, it would be like eating a used filter, that's why clams that you get in restaurants must be grown in very clean water [1].

#44Love the article, but what is this site? I can't find any info on Polish News or who runs it. No about link and all social media links are empty.

The water wasn't contaminated with lead, the pipes were. The people of Flint were under emergency management appointed by the governor, rather than local elected officials. The emergency managers switched municipal water supplies to save money. They also failed to treat the water to prevent the leaching of the lead into the drinking to save $140 a day. The water was contaminated with Legionella also, though, and that killed a dozen people. It was so bad local manufacturers had to get emergency waivers to switch back to the old water because it was corroding metal parts.

wrong. The great lakes has been an ecological experiment since the St. Lawrence seaway was opened and continued to be that when the Chicago river was reversed. There are almost no "native" species left in any of the lakes (excluding superior). If you want sustainable native great lakes ecology you need to cut them off from the oceans, re-reverse the flow of the Chicago and do a one-off massive trout and other native…
Walleye are native and have been one of the hardest-hit by the loss of turbidity. https://en.wikipedia.org/wiki/Walleye also Perch, Pike and a bunch of other species.. and I never fished for them but I know there are healthy populations of trout in the western Great Lakes, too.

I am squeamish about eating any used filters: bivalves of any sort (and other filter feeders), liver, kidney...
People have been doing so for a long time which is why I use the term "squeamish" which implies some lack of rationality.
I thought oysters were "purified" by putting them in a bucket of clean water overnight. Myth?

Whatever it is, it seems like we should put some GPS and transmitters on those clams and put them online.
IoM: Internet of mollusks. I know we’re being tongue in cheek, but I do wonder if there is anyway to actually use them as online sensors without causing too much undue harm?
Why not just point a webcam at a bed of them?
You can do image analysis to count the shellfish in the image, and attach an “open” or “closed” status to each. Once you have a reliable field of Boolean values, you can detect anomalies in the close count.
You could then have a grid of tanks with inlets from the clean water supply and outlets to the sewer where you monitored (more or less real time) the reaction to our clean water supply.

That is to let them spit their sand out, and it only takes about 20 minutes.
If you want to let them spit overnight, you should put them into salt water, fresh water will kill them.
Most shellfish for consumption are farmed, and it's really important that they're grown in clean water to taste good, especially if the intent is to eat them raw.

I don't know if it's rational or not, especially since I'm sure there are plenty of microplastics and pollutants in everything else, but I've completely removed filters & anything whole like shrimp from my diet.
I enjoy shrimp and scallops, but honestly I feel like given my current knowledge it's not worth it. Maybe we'll find out that all the microplastics in the ocean are totally fine, but better safe than sorry in my opinion.
