- Closed containment is the future of salmon farming in B.C. Sea lice infestations, farm waste, disease and escaped farmed salmon could be distant, unpleasant memories if the salmon farming industry switches from open-net cages to closed containment technology.
Great to see the cleanup of wild waters that are being ruined by net fish farms is getting some traction. We are getting rid of dams that we don't need and cleaning up the waters where salmon live. Let's hope we can see this implemented in more places and in a hurry!
what about fish food.. what are you feeding them? "Fishmeal"? where does that come from? I like that you've gone so far as to tie up all the other loose ends... let's tie this one up too.. and then we can say you have a viable solution. That done, I thank you for putting an end to an industry detrimental to our environment and turning it into one that is TOTALLY beneficial to the environment. Also, I didn't see the greenhouses that would be an awesome way to make use of the fish waste and help you keep clean water systems, so what happens to the fish waste?
Hello from the Island of Trinidad in the Caribbean, I am actually doing lots of research to implement a stable and sustainable aquaculture industry in my island, this video was very informative. I would like to speak with anyone from living oceans so i can maybe get some advice or knowledge
+Kevin Babbz you can send a message to info@livingoceans.org and we can start the conversation.
I am a bit curious? how many tuna farms exist in japan?
I start my Recirculated Aquaculture System from 2015, and now it's running successfully. I also would like to speak with anyone from living oceans so I can maybe get some advices on this field too.
Hey Daniel can you please advice how to contact you
I disagreed about why the industry avoiding to invest. Its basically come down to the cost associate with the investment. Cost of equipments are so prohibitively expensive. If there are cheaper and down to earth alternative , more farmer would join.
I love eating fish, and it would be a dream come true to raise them by myself :)

some people grow up wanting to be astronauts or superheroes... and then when you become an adult you have to lower your standards
We need this industry to boom
Won’t salmon want to go back to their original tank to breed? Will they like jump out during mating season?
6:25 the way he chucked that fish😂
it wasn't a fish
Very nice dear friend
As long as you play the carbon game nothing is sustainable! Aquaponics is very sustainable on a small basis. But we continue to move forward not letting carbon foot print be the thing that controls our decisions for making thing better. With new ways of doing things [ as long as greed and power is not there] thing will get cleaner and more healthier.
We need to do what some other does. Build a Horizontal farm, aka a tall building growing downwards or like the chinese were planning, making farming on top of the roofs of larger building complex for food sustainability without losing too much soil.
michael kindscherm Disease-that never sees the light of day
but in a closed containment you can fertilize alot of vegetables with the water it can be reused not just dumped if fresh water.
But it's salt water
Horacthy then boil the salt out
@@horacthy8577 it's fresh water
GO AQUAPONIC!!!!!!!!!!!!
+omniXenderman - Yup! Only way to grow!
JT Bear well i mean i guess you could use dirt like the normal pleb, but fish dont do very well in dirt
omniXenderman - Too true ...

Good Luck Canada.

END CREDITS BEGIN TO ROLL...
put the whole lot of them the their business in jail and sponsor new breeds of fish farmers man these people are criminals they know it's bad and it still doing it for the money. All for the Love of money mankind too wicked.
Why does the closed-containment farming industry have to pitch so hard for this practice? If in fact the public is becoming aware of the problems with net-pen farming, just get your law-makers to demand the net-pen industry pay for waste treatment, the playing field will be leveled.
sfbluestar It's a public awareness campaign thing.......
sfbluestar We've been campaigning for many years to get our elected officials to require the salmon farmers to stop offloading their 'external' costs to the ocean. The industry has a strong lobby, however, and both the British Columbia government and the Canadian government have not imposed that demand upon them.
Every analysis I have run says that net pens can economically beat recycle aquaculture systems (RAS) in sustainability, especially the Carbon in a life cycle analysis, and in large scale production costs.
That is reality. However, RAS for niche markets, broodstocks, biosecure systems research species and producing fingerlings, where the value of the product is much greater than food animals, you can afford the extra energy consumption and make a profit. I know, I designed, build and operated a totally closed RAS for three decades until I recently semi-retired and was profitable every year.
What about Aquapontics? I'm going to test if that can work, and if not i'm going to make it work.
that's my plan.
Big fish
Big money
Big fun.
Dallas Weaver i would gladly pay $4plus for a loaf of organic,un-gmo tainted,ancientgrains,than a unsustaining,degraded,man-handled 99 cents one!-Wherever there are humans there will be ''carbon'' but usually a toxic version of it.We need the Earth,but it definately could Do Without us,cause we will just bring it down.
@@temureviewsmegaload There are billions of people out there who won't pay $4 for a loaf. Or more accurately, can't.
Pull your priviliged head out of your arse. We need to science our way out of these issues. Not social out way out of them.
I would like to find a way to add a BioDigester to a aquaponic system
fish makes ur breath STINK
True
You should smell J
😂😂😂😂😂😂😂😂
Farming fish inland is great and all, but you still have to take fish out of the ocean to feed the fish on the land. It an oxymoron until truly sustainable alternatives such as insect meal can replace the fish meal that is being depleted from fisheries every day to feed the land grown fish. The only real benefits from RAS is the fact that it can be grown closer to the market in more confined spaces and there is less waste discharge.
+ridewhitehorse Feed them duck weed, it can reproduce itself in around 24 hours. It has as high a protein content as the manufactured fish food, and all fish that are omnivores will eat it. It requires some air stones in the container system you grow it in and some sunlight. The more dissolved oxygen in the water the faster it grows.
+ridewhitehorse Aquaculture technician here. The feed conversion ratios for a species such as the carnivorous salmon is much better in aquaculture then in reduction fisheries. The issue here is that a large concentration of herring and anchovy is taken from specific regions, such as Peru. Insect meals such as black soldier fly larvae are currently in the research phase. As Ginger Golden hinted to, plant sources such as duck weed and soy are currently being used to provide both macro and micro-nutrient requirements for finfish aquaculture. Hopefully, we'll continue to move forward.
Future of fish farming is in the open ocean using plastic floating like cages. Let me ask you this... where does the poop go from the fish in the tank? The answer is to the bottom of the tank all the worms and parasites are there and they will get to the fish in time. The key is to have massive space for the fish so It would be in less parasitic environment such as the open ocean.
No, the poop is pumped out of the tank and filtered.
Buddy not everyone is smart enough to do that or follows those directions so No to you too I already said everything.
You can get a filter on a home aquarium but it didnt occur to you that maybe these containment farms designed to raise huge amounts of fish might also have a filtration system?
If it is so good, why to they want taxpayers to Invest NOW. If it was economically viable relative to alternatives, it would be happening.
However, it won't happen in BC, it would happen next to the markets in California.
because open net fish farms dont want to make the switch because it is expensive and risky to business.
any sugestion what food vitamin we need to make our fish fast grow if we use fish cage in the river ?
1:01 prepare your left ear
xd Clippz oof
After all the fish raise in the container than people will say it mistreat the fish, the fish are too crowdy:(
but what about in deep winter when everything gets frozen because the containers seems to be outside and the weather is nice so what happened when the temprature drops down to minus 30
In colder climates, the tanks are housed inside buildings so there is some means of temperature control. Furthermore, the actual water temperature in the tanks is monitored and maintained at optimum growing temperature for the species being cultivated.
Living Oceans Thanks for the excellent response. I am an Electrical Engineer and have many projects of my own including building motorbike engines. But am very interested in farming stuff now because I can generate my own electricity very very cheap. This for me is a great advantage. However, the Electricity I generate takes allot of space so cannot be done for cities and town but only for personal business including growing food in winter in freezing Temperatures.
Oliver C if your going to be farming fish cutting of the power bill will save you a lot, *go green* and the less you have to deal with the city's :)
Good
To be honest, currently in China, people believe wild creatures are more tasteful, nutrient, and with many benefits compared than those from the ponds or RAS(recirculated aquaculture system). This awareness is hard to change in the coming 25 years, and this has become the difficulty for the RAS industry to grow.
Power to the people man screw fish it don’t taste nice any way but vote for whatever this is anyway coz like save environment and all that
Whether the fish is wild or penned, they all poop into the ocean. Wild poop and domesticated poop are no different.
Daniel Jean-Baptiste One difference is that the feces from farmed fish falls into one concentrated area below the net-pen which smothers the sea floor in "poop". This is fatal for crabs and other bottom dwellers. Another difference is that farmed fish are treated with antibiotics which also ends up on the sea floor, causing further problems for creatures living around the farms.
Living Oceans The only solution would be to have the pens in deep waters with a constant current, but I see your point, I don't like the idea of antibiotics in my food.
+Evolve432 Good point.
+Daniel Jean-Baptiste Net fish farms also cause localized areas of high ammonia levels, which is fatal to some types of microorganisms,while too good for others. This throws the ecosystem out of wack. Deep water net fish farms are not viable for the same reason closed containment is seen as not viable, too much cost. The price of fuel alone makes it unattractive.
Fish waste in closed containment can be controlled, where such things cannot be controlled in net fish farms.
Just research the nutrition value of those fishys
nice
how much cost would
One possible answer is to regulate human population growth. Which would in turn help many environmental issues ( like having to overfishin the oceans). Stop having so many kids and nature will start to remedy itself. boggles my mind to see families with four, five or six children. what are the parents trying to accomplish?
Ya and kids having kids... and welfare collection just drinking our tax dollars
Let's not be driven by film footage from what are basically research facilities, operating at densities far below commercial ones! If you believe that open cage farms crowd the fish, then land-based units go FAR beyond this. The sad truth is that land-based salmon aquaculture risks replacing one bad system with an even worse one, from an animal welfare point of view. In order to have any remote chance of being economically viable, land-based systems will have to cram the fish in at several times the density of cage farms. And in most climates, the tanks will be in buildings, so the fish will spend their entire lives in factories. This is NOT progress, this is regression to the worst kind of factory farming. We need an answer to the problems inherent to open cage farming - but land-based units for the fish's entire life-cycle are not the best answer. In my opinion, we should be pursuing the technologies which involve solid floating cages/tanks, so that the farmed fish have at least some access to natural elements such as seawater and daylight, but are protected from becoming infected by sea lice & hit by diseases like AGD. Fish waste from such systems can also be pumped ashore for treatment, rather than discharged into the ocean. It also seems to me that such systems, with their lower capital & running costs SHOULD have the potential to be operated at more animal-welfare-friendly stocking densities. Raising fish at densities of 100kg/m3? No thanks. Civilised nations should be leaving intensive factory farming behind, not turning to it.
i totally agree with your opinion.
Fiona Cameron Here's a link to an article in the "Vancouver Sun" about a viable land-based closed containment system: www.vancouversun.com/business/resources/only+land+based+salmon+farm+target/10818211/story.html There are far fewer fish in these tanks than in the open net-pen farms on the British Columbia coast.
Well i don't like open ocean farms, BUT the land based farms are much better, there's really no such thing as crammed, farmers put their fish in a tank that can support that fish and have them able to grow to their full length, if there is any "cramming" the fish die, the land based tanks are also very good as they can control their environment and have less disease, it is not a step back what so ever, as we are moving towards the stars for are future and we need this technology so we can have farms on different planets.
Fiona Cameron that's a fable,you weren't listening,once we clean up our act,many #smallfarm units to replace the compromised one can compliment wild catch?,,If they will even exist anymore after This.You don't see All Largescale #industryfarming-so called as unnatural,then u are grey,the sea water is probably compromised which would inturn affect the lazy lifestyle fish,and i don't see how sunlight actually affects fish much.It is too close for comfort what you are suggesting and probably more cruel,cause i think fish can hear sonic vibrations which would probably naturally depress them.Fish are at least a better economically viable choice because they don't receive the absolute and complete torture that industry homestead caged animals do.And i'm sure the older fish are removed by management before the offspring encroach!I'd rather have filtered water bred fish than the toxic dump site that is currently the Ocean!;( You can't shine a turd,after all.
Any one there to answer my query related to cost???
butt is it oky to imprison salmons when they still haw mating instincs and hunting instincs?
+Gunn Steivor Paulsen This seems as bad as the commercial chicken, pig farming. Overcrowding.
Was ninja tuna intentional lol
Aquaculture high tech!
land based systems have been used for a long time with great success for some species that have a high market value, and for specific life stages such as smolt production and broodstock holding. However, there is no proven success with raising Atlantic salmon to commercial production size yet. these projects are R&D only. there is nothing wrong with doing R&D its needed...but do not pretend its prooven to be viable. its not.
Some salmon that has been produced has been described as tasting different, some say 'buttery' some say 'muddy'...and its more expensive. Farmed salmon is able to compete in the seafood section of your grocery store at current prices...its already cost enough, who is going to buy it when the price goes up because its tank reared...that may be fine for niche markets where people will pay fro the novelty..but the average North America seafood consumer wants lower costs , not higher. this is a scam to get people to invest in R&D projects, and to make people believe that anti-salmon farming activists are offering a viable alternative that the industry is jsut too lazy and corrupt to take.
IF it is ever proven viable ,you can bet the industry will follow.
Earth Day, April 22nd, was a landmark day in sustainable aquaculture as Canada’s first-ever land-raised, closed-containment Atlantic salmon entered the marketplace. Sold under the brand name KUTERRA, the fish are raised in a facility that is fully owned by the ‘Namgis First Nation and located near Port McNeill, B.C. on the northern coast of Vancouver Island.
The ‘Namgis’ innovative land-based system in creased feeding efficiencies by 30 percent compared to conventional salmon farming practices. This means that fewer wild forage fish have to be caught to feed the farmed fish.
The ’Namgis launched the farm in March 2013 to prove the economies of growing Atlantic salmon sustainably, on land. Just over a year later, the farm’s first harvested salmon are for sale at Safeway stores in Alberta and B.C. under the KUTERRA brand name, which combines ’Namgis terms for ‘salmon’ and ‘land.’
Living Oceans time will tell if it is commercially feasible in the big picture..investment in, cost, fish sales...its sold as a more expensive product than 'regular' farmed salmon so it remains to be seen just how many people actually want to buy it at a higher price when its called something else and is said to taste different. I've heard 'buttery' and 'muddy' depending who it is.. Given that markets run by supply and demand, and business have to be profitable to stay afoat, time will tell.
as for 'saving the forage fish'...two things. 1) salmon feed has been adjusted lately to use less fish content than in the past. 2) what do we feed our pets? fish meal is a huge component in other industries including pet feed...
lets stick to the facts
Demand has far outstripped supply so the future for this product looks bright.
Living Oceans it may just fill a new market niche , that of people who think its more environmentally responsible and who are willing to pay more..., but not have much impact on the rest of the market where people want value for their money...as in not willing to pay more than they do now...like the organic produce market has added on to, not replaced, the main market for produce...
who knows...but it will be based on profitability.

1:42 *Closed containment offers so much economic potential then why is the industry resisting change?* his answer people dont like new ideas
this is wrong cause and a BS answer coming from an expert (he seems more like a salesman)
reason why vast majority of fish(almost all ocean fish ,majority of river fish,and some pond fish) cant be kept in closed containment
1-) fish bodies are made to travel long distances -keep them in small tanks(compared to the ocean) put a lot of stress on the fish. when stressed -they stop eating -hit the walls attempting to flee injuring themselves in the process. which may result into zero growth or death
2-) you might say we keep cows and chicken in small farms why not fish ? simply cause they are not traveling animals .if cows chicken goats can find food and water they would love to stay at that one place,
deer being the best example of a traveling animal they are same as a goat but are made to run with burst of speed travel long distances .if you scare a deer its natural instinct would be nost just run but run miles away .if they cant they feel like an hunter has trapped them and will do what ever it takes to escape (injuring them self in the process) ( through out history humans tried to farm deer but its never became a viable farming process)
3-) keeping cows and chicken in a small area does to cut off there access to the massive atmosphere they live in (air) . but keeping fish in a small tanks cuts of there access to the massive supply of water
think of it as keeping an human in a enclosed container under water the only supply of air being being air tanks for 3-4 years( not allowed to surface) .you have to provide the perfect amount of oxygen food temperature and hygiene every small change/delay will have a impact on the person mental and physical health
in aquaponies fish death are common
4-) fish only feel safe in large groups really really large groups other wise they feel lost or in a constant state of fear = stress=next to no growth /death
fish also like to feed in large groups -fish not eating is also a common problem in aquaponies
there are more reasons but this post is getting way to long
ending note pond fish can be easily be farmed but are generally dislike in the seafood community example being the carps in the american rivers vast majority of people hate them like really hate them i remember seeing a fisher man catching a massive carp only to make a weird face then proceed stab it and then threw it back into the river (calling it a bad tasting invasive species) if american like the taste maybe crap would not had grown in such numbers (he stabbed it so would die )
Invasive carp thrived because it has no predator and it devastates the front of the food chain. Has nothing to do with eating or not eating it.
终于可以用youtube了 自由了
seems cool
Lol propaganda. Ppl will always support ocean fish over pond fish.
@william harrison Standford Unv studies shows oceans were able to replace less fishes than what we have taken from them since 50s. So Pond culture is the only best suited practice.
Open sea farming in geodesic domes are a way better idea, this is dumb.
