Woooooo, I am doing a PhD in environmental engineering focused on restorative and recirculating aquaculture. Please keep making content like this and reach out to me at UMBC if you have any questions about aquaculture or aquatic ecosystems!
One thing DW missed is that the best location for the shells of consumed oysters is back into the water (and tidal height) they were harvested or naturally grow in. This creates a growing environment where free floating baby shellfish who are evolved to latch onto shells can further build the ecosystem in a positive feedback loop. Plus this increases the availability of calcium and other minerals present in shells for other shellfish to absorb over time. TLDR put empty shells back in ocean where they naturally grow... don't try the greenwash "cyclical" composting or manufacturing as they are likely worse for the environment
@@mervynlarrier9424 well, it certainly can be. If, in the end, the practice is still unsustainable (just slightly more sustainable) it's in the category of greenwashing.
Bivalves are a superfood in every sense. We farm mussels in the open ocean and have seen so many environmental benefits to the surrounding marine ecosystem.
Harvesting maricultured Mussels and Oysters; then Cleaning (with Tap Water), Recycling, and Reusing the Shells as Substrate to Farm more Shellfish is a Nature-assisted method of removing Carbon from Seawater (and Indirectly from the Atmosphere).
That's why depuration process is important. Depuration help to remove all contaminants from the shellfish, including the heavy metals. By putting the shellfish in a clean seawater runoff, we can take advantage of their natural ability of filtering to remove contaminant from their intestine.
Thanks I love acquaculture as engineer and study oceanography , bioinformatic in sponge cities and ports . Aquaculture and cozze are the future , of course.
This is a good initiative, but in addition bottom trawling for fishing has to be stopped. It is damaging the existing ecosystems of the ocean floor. Sure, we need to restore the ocean habitats, but first we have to stop the destruction of what we already have.
the first person to have eaten an oyster must have been really, really hungry. Imagine you had never heard of oysters and someone put a live molusc, with grey flesh coated in a thin layer of mucus, squirming in its lumpy shell. It smelled very fishy and you heard "these things are fantastic at sucking tons and tons of pollution out of the water every day!" would you eat it?
Guess what, the highly destructive and invasive freshwater zebra mussel does just that! We've already completely destroyed the populations of our native bivalves that are much more sensitive to pollutants, and these guys are coming in to take over. Of course, they are so good at reproducing and cleaning that they will completely change ecosystems, which would also kill all of their inhabitants and bring in new ones that can live there.
If bivalves are so good at filtering, is it possible that we could use them in water treatment plants as a way to cut down on chemical sterilizers? Perhaps also in water recycling and desalination?
Oysters don't desalinated water, I don't think oysters are going to be good enough to get rid of all the chemicals to be brought back to the environment, and they don't desalinate water, if they did, the ocean wouldn't be what it is today.
Super nice , plz continue the videos are very helpfull to connect to the human society we live in atm who doesn't know what we do to the mother earth.....
@@ryanbrimson8238 I know dw has already done a documentary about Ecosia but this dw Channel has not talked out them it seems like something right up there ally
@@aarononeal9830 yea like something as simple as a search engine company that has planted about 150 million trees really should be getting more global recognition
Great question! Sponges also filter water but they have special traits in their own way. We’re considering reporting on sponges in the coming months. Be sure to subscribe - we put out new videos every Friday. 🙃
Visit the Texas coast from Corpus Christi to Galveston and so on. Go to a bar one night and ask random people about oyster shots and you’ll hear all kinds of things. It’s a southern country thing I guess
We have a place down here (Captain Hiram's, Sebastian Florida) that serves oyster shots. A raw oyster with vodka and bloody Mary mix. Definitely a favorite when I visit. 😎🍻 Great video that many people need to see. I'll be sharing. Thank you!
The possibility of ingesting micro plastics and the over exploitation of seafood resources and its' impact on other marine species are the two main reasons I gave up eating seafood years ago. Humans don't need to eat seafood to survive, but all sea birds and most other marine animals don't have that option.
Aquaculture development in sponge ports , to me , can trasform the water in solar energy and sustain stadiums , aereospace hub , airports , universities , schools , joke park , research vessel doubling their potential for five or eight hotels .
All I see is deliciousness. Clam soup, clam chowder, baked mussels, raw oysters with a bit of yuzu, pan-seared scallops with butter, clam and mussels vongole pasta, bacon wrapped scallops, grilled oysters with ponzu and butter, etc. etc.
Seems like these could be used in waste water treatment plants as well. Such plants may need to be bigger, but they would need less chemical treatment. And one could even be left with more useful products. Their excrement sounds like a fantastic source to mine for nitrogen fertiliser. And then the various uses of the shells. If oysters farmed in such a way are not palatable to people, then it would definitely be useful for animal feed. For example. It could be used in aquaponics or fish farms. In such a way fresh water would not be needed for waste treatment either, but rather seawater. It should at least be an option relatively close to coastlines. Which are where the majority of people on Earth live.
A lot of people don't seem to understand bivalves need clean water too. They aren't just filter feeders, they also need well oxygenated waters that are low in toxins. Pollution is literally killing all of the native north american freshwater bivalves and no one seems to even notice them dying. Pretty much no bivalves could survive in a wastewater treatment plant, unless you made an entire bay of them and just slowly trickled in a small amount of sewage that would not even come close to meeting the efficiency requirements.
@@derpychicken2131 Fair point. Though you are specifically referring to freshwater bivalves. I imagine oceanic species also have an upper limit of tolerance. And of course waste water doesn't only contain human waste.
@@joeblack4436 yeah, it also contains toxic runoff from that wash from lawns and roads carrying all sorts of nasty oil and chemicals if the plant is a sewage and storm drain management site. And to the saltwater question, I’d doubt you’d want to spend fortunes on expensive sea salt with the right mix of minerals and vitamins to ensure bivalve health, and then flush out the saltwater into many areas that usually drain freshwater. You could desalinate the water of course, but even plants near oceans will dump out freshwater. There’s also a reason why you don’t see desalination plants everywhere, it’s insanely expensive.
@@joeblack4436 why would they have a higher tolerance? the main difference is they are adapted to sea water. Most waste water cannot be treated by filtration species because of the heavy metals microplastics and other toxins which do endanger many oyster species. They are having so much success in NYC with oysters is people people buy them, therefore its making the restaurants money. There is no demand for non-edible Oysters, especially when we already perfected fresh water filtration on a large scale.
@@Brurgh Not saying higher tolerance. Merely that they also have an upper tolerance. What is pertinent however is that ocean water is a much more plentiful resource than fresh water. Making larger schemes with lower concentrations possible. That said. From my discussion with derpy it seems you would need an unrealistically large installation even so.
I didn't know they meaning of it but I've always heard my boss say "ASAP". Like, "we need this done ASAP". So he meant oysters, mussels and clams, huh. Now I know what he means when he says ASAP.
I've been studying only the animals for school (amazing text highly recommended) and one of the stories is about mussels so it was kinda scary seeing this in recommended but hey I like learning about this things more they're really interesting and cool creatures that are rather unappreciated
Thank you for your feedback. Acidification of water means that there are lower pH levels in the water (which means less carbonate) - this is an essential element that oysters rely on to build their shells. As acidity increases, shells become thinner and slows down their growth. It also increases their death rates. We try our best to put all the information in a 10 min RU-vid clip and also offer read more links in the description for extra information - so don't forget to read those papers!
Good question! Thriving native biodiversity can help improve river and lake water resiliency. ✨ Be sure to check with local biologists to know what region-specific plants and animals are most appropriate.
I love sea food, but they have to take care of the jobs they have. I hope the people who enjoy them as food can enjoy the help they can bring as well and allow it.
There’s definitely cases where we attempt to eat invasive species. It’s a multipronged approach in the end. The mussels and oysters strike me more as us going “ya know, evolution spent millions of years making a creature which is really good at this function. Then we ate it to an extent where the population was too low to perform. So how about we just go and reverse that?” In other words: no need to reinvent the wheel.
We need to eat Marine Life in limit. We can't just keep eating them at the rate that we are. We should eat in moderation. Just because something can be eaten does not mean that have to eat it.
Isn't that exactly the opposite of what this video suggests? I mean, if sustainably farmed I guess it should be fine. As long as they replenish as fast as you farm them, but I don't think that's the case most places currently right?
@@0xszander0 The way we farm them we replenish the stocks at least as quickly as we harvest them. And the process of producing them absorbs carbon and also creates habitats for other species along with many other benefits.
Hi Max, this is according to an analysis by the World Wildlife Fund and carried out by the University of Newcastle in Australia. You can read the report here: awsassets.panda.org/downloads/plastic_ingestion_press_singles.pdf
@@DWPlanetA thanks for the reply i'll have to read up on this, i knew that we already at a lot of microplastics but i never thought that it could be in such large quantities now.
Sorry to hear you're having a problem with the sound. Have you checked the audio on your computer? It seems to be working on our side. Let us know if the problem persists.
People. You over fish. Now most of them gone. Then. You over bottom feeder. Now most of them gone. Now you left with shell fish. Grow your own sea weed, fish, bottom feeder, shell fish to eat.
Oysters and muscles like trees are to valuable to be destroyed. They need to be protected for the and indirect and sometimes direct benefit they bring to us.
