We Must Start Using The Ocean As Farmers Instead Of Hunters – The Case For Fish Farming…

We Must Start Using The Ocean As Farmers Instead Of Hunters – The Case For Fish Farming...

We’re headed towards a global food crisis: Nearly 3 billion people depend on the ocean for food, and at our current rate we already take more fish from the ocean than it can naturally replace. In this fact-packed, eye-opening talk, entrepreneur and conservationist Mike Velings proposes a solution: Aquaculture, or fish farming.

“We must start using the ocean as farmers instead of hunters,” he says, echoing Jacques Cousteau. “The day will come where people will demand farmed fish on their plates that’s farmed well and farmed healthy — and refuse anything less.”

Mike Velings is the co-founder and the driving force behind Aqua-Spark, a global investment fund for sustainable aquaculture, combining a healthy financial profit with environmental and social impact. Check out his talk on the case for fish farming below…

There are some really good results coming from this method. Best part is that some of the companies are using these fish corals as mobile fencing (like cattle herders did) and imitating the natural feeding habits of multiple endangered species, while also keeping out invasive/detrimental species.

With extreme caution, we have entire ecosystems in Tasmania that are struggling due to the impact of fish farming. Then look at the fake food ration the fish are fed and the resulting nutritional content of the meat afterwards. I believe it can be done but profit should not be driving it.

    I agree Dalles.

    Same problem in Malta. The feed given causes lots of sludge that washes up on beaches & coastline. And most of the fish farmed is shipped to Japan (other side of the world) as a delicacy, not to feed any hungry.

An interesting argument. Its major premise, however, is to adjust to growth with more growth. An expanding human population requires more food. All solutions that don’t recognize that growth is ‘the’ problem will lead us to the same disastrous end. We need to wake up and deal with growth.

Vertical Farming via Permaculture techniques. It’s a thing and it can be done to where farming fish actually works as an engine to repopulate the oceans AND feed people at the same time. Requires us to try new things and to do so with an abundance mentality and while listening to natures patterns.

Reply

Salmon aquaculture like many forms of commercial farming demands the use of antibiotics and food additives. Chemical treatments for sea lice takes place in open sea pens that affect other species (lobster). In areas where wild salmon populations are in decline or endangered (Maine coast), land based salmon aquaculture technologies should be adopted. Farming the ocean is not the answer to feeding the world. Just look at the cost of salmon in your grocery store. This is not an effort to feed those threatened by food insecurity.

No we must NOT start using the ocean as farmers….we already have a dying planet due in a large part to unsustainable FARMING methods. Wherever there’s farming there’s unsustainable greed and unfortunately avarice buries good sense every time. The ocean has already been raped, pillaged and polluted to an almost non recoverable state. What we need is to develop vast marine reserves and prevent the current abusers from finishing off the task to which they have applied themselves with sadly very sustainable fervour!

I´m glad to see all the sceptical comments here. We have seen what happens in Norway, and now some profitmakers are trying to establish fish farms in the vulneralble inner waters of Denmark. Fish farming in the ocean is NOT at good idea. And it doesn´t bring more food – I heard that it takes as much as 7 kg feede to produce one kg fish. And have you ever tried a salmon from a fish farm? It has no structure, no taste, just a lump of BLAH. … nothing like the fish caught in the wild.

So far fish farming has been an environmental disaster. From introducing pathogens from Atlantic waters to the Pacific, to the detriment and decline of native salmon, destroying mangrove forests in the East and Pacific coasts….those mangroves are just as important as the declining coral reefs in terms of being nurseries for juvenile fish. And if anyone that reads this is eating farmed shrimp or prawns (farmed is anything not wild caught, no matter what the package says), let me tell you about the time that we were cleaning some recreationally caught wild prawns when Eddy, a Filipino arrived. He bragged that in his village the shrimp from their salt pond were much larger. He also said that much of the village waste, including dead cats and dogs, were tossed into the pond. Hungry?

    Nathan Anderson According to the industry (I checked about 5 industry web sites) takes 1 kg of feed to produce 1 kg of farmed salmon and 30 – 40 % of that feed comes from wild caught fish. (Salmon is the most abundant farmed sea food.) About 90 % of this wild fish is fit for human consumption so why not just eat the wild fish in sustainable quantities? This would remove the added problems of sea lice, disease, water pollution, removal of wild habitat to farm that also occurs with aquaculture.

    Reply

Cuz that worked out so well with salmon. ?

Reply

Fish farms are no better and probably worse than battery hens or any other caged creatures for consumption by man. They are fed pelleted food and antibiotics which spread into the surrounding area upsetting the ecosystem. The fish are packed into these pens with no room to swim, they are more susceptible to infectious diseases, hence the practice of using antibiotics. Man needs to manage what there is for the benefit of the planet not take, take, take because he can. A change of attitude not a change in farming is needed.

Reply

So what you are suggesting is that we enslave the fish as we did with land animals and produce them as things instead of beings!?

The threat he describes is very real, but the solution is not to produce more to feed the growth in both numbers and consumption. We need to tackle the issue of growth head on. Growth is what is not sustainable.

guess what? we DO NOT NEED TO FARM OTHERS. Eat a fucking plant, for christs sake.

Reply

When we humans farm, we impact the surrounding ecosystem. When our farming consists of raising animals that must be fed, the impacts include all those involved with both feeding the farm animals and the wastes those animals produce. Farming concentrates more animals into smaller areas than those areas can sustain, and the more concentrated the farming is, the greater the extent of the damages.

    Mark Eastaugh it takes 4kg of small fish, often fished in polluted waters to grow 1kg of salmon. The European health monitors have said that because of dioxin levels in farmed fatty fish, simply eating 185g a week exceeds the safe threshold.

    Reply

    Mark Eastaugh Yes they would produce the same amount of excrement, however, there would be no excess food in the water and the fish would not be schooling in such tight locality. Nature has a wonderful mechanism for ensuring balance and sustainability of eco-systems. If too many fish were in one area, the food source would diminish, then the preditors would, then the food source would recover… (predator-prey cycle).

Reply

Fish farms are found to be damaging to the wider ecosystem as the large confined populations are a good habitat for parasites and diseases which wild fish can pick up. Also there are regularly accidental releases of large numbers of farmed fish which then contaminate the wild gene pool and transmit pathogens. Plus not good for the welfare of the farmed fish.

Stop eating animals. Eat the plants that are grown for animal food and we have enough.

Reply

    Veganism is not sustainable either – it depends where you live.

    Not all countries grow feed for animals, in fact many do not. Many use natural pastures and areas of land unsuitable for cultivation in order to rear animals. In these areas eating meat (at a reduced consumption – not every day) is far better than eating nuts, avocados, palm oil or soya which has been grown in tropical climates, often by underpaid labourers, and transported (often by plane for fresh produce) around the world for consumption. Let alone the deforestation which has occurred in many of these producer countries as they seek a way to compete in the world economy and see the increased demand for high fat and protein-based plant products as an easy market.

    People should eat what is locally available – for instance in Europe meat, root vegetables, wheat, and legumes were the majority diet before globalization. These are the foods which can be sustainably produced in the region. Eating a diet following these foods means that the overall environmental cost of your food is likely to be lower than if you were vegan eating nuts from South America, Soya from Asia, Bananas from Southern Africa, Avos from Australia etc. Furthermore, by incentivising these countries to export produce puts the local communities and population fo these countries at risk. This is very much the case in some African countries where food exports have driven local prices through the roof that communities which had access to a balanced, and healthy diet are now reduced to only being able to afford imported corn and wheat products as their fresh fruits and vegetables are overpriced to international demand.

    Reply

    Mark Eastaugh I’m not arguing against farmed fish, I’m arguing against using the oceans for this purpose. If you look at fish farming it has been done successfully for freshwater species, with a limited effect on the environment. However, there can still be an effect. In one of the natural fisheries my club managed, the e-coli levels in the crystal clear water where dangerously high and this was traced back to an upstream fish farm who were not managing the outflow of their ponds directly. Furthermore, fish sometimes escape these farming operations and have had a hugely negative effect on indigenous species who become prey to a predetory fish that should never have reached their eco-system.

    While those cases are freshwater based, and based on my own experience of being involved in the management of recreational fisheries, the situation is far more pronounced in sea based fish farms.

    There are 2 main types of ocean based aquaculture. Pods in the ocean, and land based pods.

    Land based/isolated pods are a far better solution as the effluent water can be directly processed and pumped back into the ocean. Furthermore, disease outbreak can be contained and treated directly. However these operations are difficult and expensive to setup and manage.

    Thus farms prefer using ocean based pods. Firstly the fish species farmed in these pods are migratory fish who usually have a huge territory, these fish are now over stocked and contained within a relatively small pod. Thus the build up of organic matter in these pods is huge, causing breeding grounds for diseases and parasites like sea lice. 5 sea lice on a young wild fish is generally enough to kill it, thus destroying the breeding stock of future generations (this is the case of wild sea trout populations in Scotland) where a fishery which was productive and protected for hundreds of years has been brought to its knees with the introduction of sea based salmon farms in the area. Apart from the increased levels of parasites on farmed fish (usually each carrying a few dozen sea live each) the increased organic matter leads to unhealthy fish which is not totally safe for human consumption due to increased mercury levels. Fish farming suffers many of the same problems as battery chicken farming, except in the case of battery chickens we have control over the surroundings while in Ocean based farming we basically taking the same approach as mines used to, by dumping waste into a river/the ocean and arguing the currents will disperse it.

    Mark Eastaugh this is the poorest of arguments and could easily be flipped around to say: we need to remember that aquaculture is much bigger business and drives bigger profits than traditional fisheries and thus they have extensive marketing campaigns and fund environmental organizations to promote their damaging practices in the name of profits.

    Mark Eastaugh as a scientist myself, I see the importance of this and will get back to you on it as I will need to find these sources again.

    However, it is important to remember a few things when calling for scientific papers. 1) a simple Google will yield papers on any result you wish to prove – just because there are papers it doesn’t mean they are worth anymore than a personal opinion. 2) funding plays a large part in scientific research and honestly as bad as it is, people reformulate their results to tell the story that will ensure they get more funding. 3) negative results in science are highly stigmatized and not accepted in many fields, thus only one side of the coin is shown. Papers which say ‘hey we don’t really know, the data is inconclusive’ very seldom get published.

    I’ll find some resources which I have used, and link them here

    Based on those resources it is clear that we do not yet have a good enough understanding of the oceanic environment to be able to say fish farming is a viable and safe solution.

    However, the findings do highlight numerous dangers, and issues related to fish farming – even though these findings are related to the placement, density and management of farms they head a strong argument against fish farming as the potential negative effects of sea-based farming far outweigh the potential positive effects.

    What I haven’t included is the medical research showing the dangers of consumption of farmed/anti-biotic fed fish.

    Essentially advocating for fish farming is in the same line as advocating for factory farming of chickens, pigs, cows etc. We are well aware of the negative effects of these on the quality of the produce, as well as on the welfare of the animals involved. We advocate for better farming practices on land, but when it comes to the ocean (which we understand even less about) we are fine to follow the very approach we know doesn’t work on land.

    There are only 3 ways in which we can live sustainably on this planet: 1) Reduce the population to the point where communal food systems can be re-initiated and the reliance on industrial food can be decreased, 2) Eat a diet which is regionally feasible so that your reliance on industrial food is reduced, and the overall, full lifecycle of your food has the lowest environmental impact and 3) reduce your consumption of meat and fish, and ensure what you are consuming is from a sustainable and human source.

While fish farming / aquaculture is a great idea and has been practiced in one way or another for hundreds of years it will not be a blessing without an “real” downsizing of human populations world wide. Increasing this activity increases ocean pollution. Our oceans are already at the point of collapse. We have already seen many fish stocks crash and others are right on the brink of collapse. Homo sapiens are the only animals that defecates in its nest and will be up to Homo sapiens to straighten out their mess and quickly as measured in a couple of decades.

Fish farming is fraught with pitfalls. I think a better solution is just to fish less. The motivation for farming or catching massive quantities of fish is profit: more fish = more profit. It won’t be easy to downsize, since so many livelihoods depend on it, but over-fishing and the downfalls of farming fish will ultimately be far more damaging to those livelihoods. Consumers are also to blame, since they continue to consume in wilful ignorance of the consequences.

    More importantly, that to fish less is to fish well.

    Much of the damage of ecosystems comes from non-selective fishing methods which cause huge reef damage, large amounts of bycatch (which is often just dumped into the ocean and dies as a consequence of stress). Our current methods of fishing could be likened to going hunting for a deer but shooting everything you see just in case it is a deer.

Stop population growth – stop pollution – stop mining – work towards peace – care about each other, animals and our world – try and be a good person —- I know many people who are vegetarian but not particularly nice people

Why not farm fresh water fish for the table in the vast inland reservoirs we have, or in conjunction with them. Knowing the water output will be filtered and sterilised before being recycled.

A lot less to go wrong in a closed system inland water body than the ocean.

I will not buy farmed fish, I was put off seeing them in Vietnam. Our food is already of questionable quality unless you have money for organic and the Industry is only about making money. Can you imagine what the fish will be fed to maximise profits?

Reply

They will just be grown in sewage ponds like the talipia, shrimp and catfish are now! Humans cut corners to make money at every turn…until we are all sick or poisoned!

I just read another article saying how bad farmed fish is for people to eat

Reply

The resulting food is toxic.

Reply

    Dalles Hayes however we must hunting in the oceans. This is also toxic

    Reply

    No I disagree, it is the method of hunting in the oceans we need to moderate.

    Reply

    Dalles Hayes so sorry – typo. We must STOP hunting in the oceans. We are decimating the seas. If you want to eat fish, eat the farmed stuff and sort out the problems.

    Reply

    Jodie Hayes Again I disagree, the farmed stuff is destroying the estuaries which is the nursery for many species of fish. Remove netting and set lines perhaps from hunting of fish.

    Reply

    Turn Sea world into a closed loop aquaponics establishment, that kind of fish farming perhaps. But they need the animal proteins so feeding them farmed insects perhaps. They simply cannot use the natural waterways with their current methods.

Farmed fish is full of antibiotics and poison the water ways

No it increases ocean pollution
