This is another way of doing it. I will have to take a screenshot of your idea and work on it to better improve my plan. Funding has been my setback so far

That amount of algae will kill any life around it. It's even more unsustainable. Think simpler, decentralised and use what nature already provides.

We run into that conversion rate of wild fish feed vs marketable salmon. Wild salmon are voracious predators, and more than likely ate far more than 1.5 times their body weight at time of capture. The wild salmon predate on a variety of other marine organisms, some of which might face their own existential threats; by feeding fishmeal to farmed salmon, that might take some pressure off other species in the wild. Fishmeal typically is produced from small fish low down the food chain, often filter-feeders, such as anchoveta caught off Peru. Our question should be: salmon or no salmon, rather than farmed vs caught. A few years ago, salmon was cheaper than beef. That is out of kilter.

This is what cannabis induced dreams look and sound like...

😅 it's actually brilliant

I wast thinking the same thing, there should be grades of sustainability when buying these products where ocean farms run on fossil fuels and use hormones and chemicals get a 1, and something like a closed system aquaculture like you described run on green energy gets a full sustainability rating, for the little bit of seafood I do eat I would pay a premium for that.

Yeah, I see it in the Chinese system, and I think they add something in the bottom like sea cucumber to eat the waste that drops on the floor.

The numbers don’t add up on that, too much effluent comes from salmon cages out in the sea waters, the mussels would be buried. And they’re a bit susceptible to the chemicals that the farmed salmon are routinely dosed with to try to deal with sea lice parasites and any disease outbreaks; not quite what you want in your moules marinères…..

DEEP SEA AQUACULTURE SOLVES MUCH OF THIS!

@walkingfish7123 Where are you? Is it possible for a customer to buy your fish??

@grovermartin6874 I'm in Arizona and I'd like to sell but my family loves fish and we don't grow much more than what we eat. I'd like to expand but it is a part time job to keep them on my table

Large scale fishing disrupt their habitat and affect their ability to reproduce

Bring down the Snake dams

A large issue is on those hatchery fish we see an average of like 2-10% returns. We are also raising retarded fish in concrete tanks nothing like the river systems they are going to be living in. We allow people to walk up and feed them and unnaturally keep them protected from predators and disease instead of teaching them survival capabilities.

Let’s keep pushing to take the dams down! It’s the only way they will return meaningfully

Probably a lot of pollution too

The salmon farmers are constantly breaking regulations.

Most fish farms are just disgusting- its not easy to grow salmon

It is indeed highly hypocritical of allowing the release of salmon/trout into non native habitats for recreational fishing of all things and call for the regulation of fish farming, however i think this is a step in the right direction, and there's absolutely no reason why multiple problems can't be tackled at the same time.

In Scotland the only "ranching" projects hailed a succes are those originally funded by the salmon farming industry as outright greenwashing campaigns. If the fish are returning, then the farms can't be to blame. However, in each of these cases, the same low return percentage is observed as in other rivers in the aquaculture zone. Tagging studies have yet to release data @@quitlife9279

I wonder why they never thought of that. I mean, that was my first thought when I conceived the idea of farming fish. Grass and silver carp reproduce in record numbers so there will be a constant supply of food for my main stock, and plus they help filter a bit of water and clear debris/grasses

​​@@bidav2114 Asian carp taste good with cajin spices.

@@Murray-wk3hz so I've heard and I intend on doing myself the honour of tasting such delicacy one day. I heard pikeperch taste great too...I do have a list of fish species I'd love to raise. I favoured trout over salmon though it not a popular idea out there

Good idea but you'd have to subsidise the production as they're kind of a pain to get out of rivers. You would be competing with trawlers in my own home of Thailand that go all over the world and scrape the bottom of anything alive and turn it into protein for fish/shrimp food. This is very destructive, probably illegal and the chef's kiss is that they often use slave labour on the boats -- you work on a boat that doesn't land for three years then they tip you over the side instead of paying you. If we could get rid of that nonsense, I'd say that turning insects into fishfood is the best bet.

The size of the fillet of an Asian carp is relatively small compared to the total mass of the fish. They are less than 30 percent of the weight of the fish. That leaves lots of carp to grind up and turn into fish meal. @@Murray-wk3hz

Great comment but surly it takes more than 1.05 kg to make 1 kg of farm salmon ?

@@mikemckelvey7144 Yes, the food conversion efficiency (FCR) is 1.05 kg of dry wt feed in and 1 kg of live salmon out. These are typical FCR for salmon and other fish (note it is dry wt to live wt conversion so the thermodynamics is also correct). I was producing and selling 20 million fish/yr with an average FCR of 1:1 for ornamental and research fish so I believe the numbers. Experimental diets have gotten to less than 0.75 kg of feed/ kg of live fish and it looks like 0.9 may be commercially feasible.

Why are you throwing it away? Surely you're throwing money away?

You should phone your local bait manufacturer, they make it into berley, you could get 50nc per pound plus. You

Then throw tons of salmon and repeat it 😂

americans don't eat carp. I do love Dace, and it is great for Fresh water systems. I think the Filipino is mixing Dace and Tilapia because they live in different part of the pond and both can survive in high density ponds, but I hate, and really hate Tilapia.

I was just about to post about that. Shows how little the American public really knows about aquaculture when newspapers are heralding decades, old technology, as revolutionary.

@@doylethelovely2555 FT is a British publisher.

@@doylethelovely2555 I see the reporting as nothing but a marketing scheme promoting it, but most importantly if after all this time the industry still hasn't fully ironed out a perfected production process, that seems to the the biggest problem facing it.

yah but this is salmon not tilapia where the salmon is much easier to get sick

its not even half of a wild caught chinook salmon.....

my thoughts was the same. Also cod oil in store, that should contain high level of omega 3 - if cod is raisen indor or on a farm, is it the same issue?

@@danielwieczorek2647 just feed it algae. that's where fish get their omega

U need to make it into pellet first

they have the insects for that. they just need to feed them seaweed

These fish are modified to be sterile to ensure that in the extreme case that they enter they environment, they wont pass down their genes and compete with native species in the long run. Also your claim of "no guidelines" is untrue. It is illegal to grow these fish outside of land based facilities. Aquabounty (the company that designed and grows these fish) is under strict regulation to ensure that they don't cause any harm to the environment by completely isolating them on land based farms.

@@ramyesteitieh3937 Are they modified to be sterile using a foolproof method? I've read that the way to make them sterile is by pressurizing the newly fertilized eggs, which might not be 100% even if it is close. There's also human error and human intervention to consider. You're right about my 'no guidelines' portion being untrue. It had been years since I'd thought about it, that's on me. However, what do we know about transport routes and methods? Is there live transport? Are routes near water? Are the sterilization methods 100% with no possibility for human error? How secure are the facilities where they're grown? Can someone unauthorized gain access? What is the hiring process of the company? Can the company say for certain that an employee will never do something that ends up causing massive damage either intentionally or otherwise? Is that a risk worth taking? If it is, why is it a risk worth taking? The same facilities could grow non-gmo salmon and still profit and be a successful business, so my opinion will always be that the added profit isn't worth risking the potential outcome listed in my original post.

@@jpjpJPJPG To an extent I agree with your points because the cost of letting these salmon out would be massive. After diving deeper in the matter, I agree that the method of sterilization isn't 100% full-proof. In fact, aquabounty's average sterilization rate was 99.7% with a range of 98.5% and 100% according to the FDA report. While this may seem threatening, several factors must be taken into consideration. 1. Shipping methods: aquabounty only ships these salmon live when they are still eggs. They also have several levels of secure transport and handling. 2. Odds of hatching: In the theoretical scenario that the eggs are released into the environment, their hatching conditions need to be perfect. Salmon eggs need a specific temperature, flow rate, depth, and water quality in order to hatch. If this does occur, and some of the eggs hatched are diploid(non-sterile). The fish then have to survive the harsh environment that usually eliminates 65%-95% of all salmon hatchlings before they get to breed. While all of this is extremely unlikely, the possibility is there and in the scenario that these GMO salmon are introduced into the environment, I think Aquabounty should probably cease to exist. Not only would a GMO escapee destroy the company, but it would severly damage the biotech industry. Public trust would go down the drain. As for the other questions you asked such as hiring and malicious release, I don't have a clear answer and those are all very good questions to ask. Everything no matter how clear cut can go wrong if incompetence is allowed to fester. I think growing non-GMO salmon might be viable, but you'd have to compare the costs to traditional farming/harvesting techniques to accurately tell. Overall, I do think that these salmon are a step in the somewhat right direction. They can be obviously improved upon (both in nutritional quality and in environmental safety) but given the growing population/demand combined with the decimation of wild salmon, we need sustainable alternatives like this to keep up. All technologies need to start somewhere before being improved upon.

Can the world be fed on an agriculture system that operates on "homestead" style production? That worked up until the early 1900s, where most of the produce was consumed by the people who lived on the land. The surplus was then traded in nearby towns and cities. www.loc.gov/classroom-materials/united-states-history-primary-source-timeline/rise-of-industrial-america-1876-1900/rural-life-in-late-19th-century/ "When did America's population become more urban than rural? The 1920 census marked the first time in which over 50 percent of the U.S. population was defined as urban." "The United States began as a largely rural nation, with most people living on farms or in small towns and villages. While the rural population continued to grow in the late 1800s, the urban population was growing much more rapidly. Still, a majority of Americans lived in rural areas in 1900." "New machines for use in farming were invented in this period, but horses, oxen, and people still provided most of the power that operated the machinery. While farmers now produced cash crops (crops grown for sale), they were still remarkably self-sufficient, often making or trading for nearly everything required by their own families." "Perhaps, it is that self-sufficiency that gives rural life a special place, even today, in the minds of Americans. As you read the documents in this section, try to infer what makes rural and small town life special. Do those qualities still exist in rural and small town America today?

Sure, that sounds like a great idea. Shut down the most efficient farms that grow food for humans. What could go wrong?

@@gilbertnail7266 Because salmon from one of at least three sources is really the cornerstone of global nutrition? I think we’d manage. Alternatively, it could be phased out with public and financial support over the course of a few years. I hear they didn’t warm to that option.

@silverXnoise There is a lot more than just salmon. Offshore fish farming produced about 29 million metric tons, or 1/3 of all aquaculture production in 2016, the latest year of statistics available from the Food and Agriculture Organization, and it has only grown from there. I think it makes sense to put some limits on the types of fish so they aren't introducing invasive species into an area in the event of an accident, but putting a wholesale stop on offshore farming would be catastrophic to the global food supply. I farm fish myself in the Philippines. We do it in earth ponds. We use the waste water to fertilize our gardens and get fresh water from the river adjacent to our property. All of this takes energy to run our pumps when we need to change water. With good management, we average production of about 7 kilograms of fish per square meter per month. Short of possibly farming insects, there is no other crop that can feed so many with so little space. The RAS (Recirculating Aquaculture System) in the video takes far more energy and maintenance than our earth ponds, but they can run a higher stock density. Offshore farming in cages in a moving body of water is far more efficient and natural than our earth ponds or an RAS. In areas away from water, an RAS can provide one of the most efficient sources of protein production while also conserving water. In areas close to the ocean, offshore farming is an excellent way to take pressure off the local ecosystem by farming a small area instead of potentially overfishing a large area. There are complaints of pollution, but the currents distribute the nutrients from the fish excrement over a large area and support plant life while excess food is also distributed, helping support native fish. The population of our planet is growing. We must continue to grow our ability to feed that population. Short of maybe switching our diet to bugs and worms, farming fish is the most efficient way to increase protein production and offshore aquaculture is the most efficient way to farm fish.
