Alternative Aquaculture Systems

Industry Overview

picture of land based aquaculture in raceway tanksThe Aquaculture industry blossomed rapidly, and became a significant supplier of food over the last couple of decades. Aqua Farming is now practiced worldwide, each year it increases in scope and significance. The aquaculture industry grew out of necessity, the chief reason being that the traditional practice of hunting and gathering of food by fishing became unsustainable in many areas of the world. Read More Here



Growth Trough Innovation

The need for change in seafood supply lead us to Aquaculture and now the need for changes in the way we farm fish has lead us to developing alternative methods to conduct aquaculture in a more sustainable manner. One of new technologies that are having a tremendous impact upon the way we farm fish is land based farming in enclosed tanks using water recycling systems. Read More Here

closed loop aquaculture using aquaponics An innovative combination of fish and vegetable farming methods that is experiencing renewed interest and rapid growth around the world is Aquaponics. This farming method is essentially the rebirth of age old practices and is now used to farm vegetables, herbs and fish synergistically. It is an eco-friendly way to naturally produce quality food for home use or for sale. This scalable farming method is being embraced by many small home growers and even large operations that are using the process and methods as a means of producing sustainable fish and plant crops.

Aquaculture Industry Size

Aquaculture, probably the fastest growing food-producing sector, now accounts for nearly 50 percent of the world's food fish. The reason for this is very simple, aqua farming is the best and most sustainable method to meet the demand for fresh seafood products that our population creates. It is now a widely held view that the worldwide biomass of wild fish and shellfish (stocks) are continuing to be depleted at a rate that surprises even those scientists that made dire predictions a few short years ago.

Sustainability and Aquaculture

People have been farming fish for thousands of years. Today, a wide range of plants and animals are grown in aquaculture farms both on a commercial scale and subsistence level. As a result of the growing world population and a shift in western societies towards healthier eating patterns commercial scale fish farming has had to expand to fill the need for fresh fish and seafood. Aquaculture is well suited to meeting this increasing demand for seafood. Out of need, we realized as a society, centuries ago, that we could not sustain ourselves with hunting and gathering of land foods. Much the same today, we must also face the very same facts when it comes to harvest of the waters.

Commercial scale fish farmers and western consumers are not the only beneficiaries of increased aquaculture production. Several low-income food-deficit countries are big aquaculture producers. In these countries aquaculture contributes to poverty alleviation and to the enhanced supply of fish products to poor people in rural and urban areas.

In addition to the massive direct food production benefits, fish farming technologies also play a supporting role to the wild fishery by making possible fish restocking and enhancement activities and by filling a complimentary niche in export markets. Indeed the sharp decline in some “wild fish Stocks” is mitigated in part by supplemental production of young seed stock in hatcheries.

The inherent efficiencies of farming versus fishing for the wild catch (hunting) will continue to further a progressive switch from fishing to fish farming. In the late 1990’s the FAO estimated that the cost of catching fish in the wild, on a global basis, was already about 25% higher than the true value of the catch. Much of the difference was made up in subsidies and other forms of financial support.

Alternative Production Methods and Advancements in Aquaculture

Land based aquaculture is a food sector that is sustainable, renewable and provides safe high quality food products to consumers while creating considerable benefits for the general population. Based on science and technology, it is a market driven sector that has emerged to provide consumers with value, taste and convenience in consumption of seafood and other Aquatic products similar to that expected from other food commodities.

Aqua Farming requires clean growing waters to maintain a satisfactory level of production. Therefore, the industry has to encourage environmentally friendly practices and has taken many practical steps to protect the local environment. In fact without ensuring protection of the environment, the industry itself would flounder. Such safeguards include government measures controlling the introduction of new species and the transfer of fish, fish health protection, better site selection, and actions to minimize fish escapes and prevent waste discharges.

Land based fish farms that utilize technology to recycle and reuse water supplies and to prevent waste discharge and fish escapement are among the most eco-friendly and sustainable methods of aquaculture. Farms that incorporate water recirculation aquaculture systems into their design are proven to be the most eco-friendly of all commercial fish farms.

Taking these systems one step further involves the incorporation of polyculture techniques, where plant crops are grown with the nutrients produced by the fish crop. This is known as Aquaponics a farming technique that is becoming more common in the design of both small and larger scale farms. Land based farms using Aquaponics is one of the most promising of alternative aquaculture practices.

The Need for Aquaculture

Aquaculture is probably the fastest growing food producing sector in the world. During the past three decades, aquaculture has expanded, diversified, intensified and made technological advances. The potential of this industry to enhance local food security, alleviate poverty and improve rural livelihoods has been well recognized

The present level of aquaculture production was driven out of necessity. Just as Agriculture became imperative to the existence of mankind, so now has Aquaculture become the only sustainable method of producing high quality seafood. One needs only to review commercial fishery statistics to see that the world's demand for fish and seafood has exceeded the levels that hunting and gathering wild fisheries can support. Recent data suggests that aquaculture now accounts for over 50% of the entire worldwide seafood supply. It is estimated that at least an additional 40 million tonnes of aquatic food will be required by 2030 to maintain the current per capita consumption.

Introducing New Closed Loop Aqua Farming Blog

To better define and provide information on aquaculture and aquaponics, I have begun a new blog that will focus on the topic of Closed Loop Aqua Farms. Where land based aquaculture is integrated with aquaponics and other farming methods designed to make maximum use of resources and farming bi-products. The new blog is titled Closed Loop Aqua  Farms. It can be found at this link

I will continue to post information here that is more specific to Aquaculture only particularly intensive land based farming using water recirculation systems. Of course recent and relative news will be blogged on both sites where appropriate.

This should help provide my readers with more more information that is better presented.

The new blog will focus more on the topic of aquaponics and poly-culture farm scenarios.

Closed Loop Aqua Farming Blog

The Image below is an illustration of the Closed Loop process that I will be blogging on.


Thanks for visiting. I hope you enjoy reading my stuff. If you do tell a friend about it!

Loblaws moving toward selling only sustainable seafood

Loblaws a Canadian food chain that boasts it is the country's largest buyer and seller of seafood, as begun introducing its sustainable seafood drive in 18 stores before a national rollout.

The grocery giant's goal is to sell only sustainable seafood by the end of 2013. Shoppers are already encountering some empty trays at some Loblaw fish counters. The empty trays contain signs pointing out that Chilean sea bass, orange roughy, skate and shark are species at risk. Eco-friendly alternatives – such as sablefish or Pacific halibut instead of the Chilean sea bass – are suggested as alternatives.

To guide seafood buyers, Loblaw also posts certification labels from the Marine Stewardship Council, a non-profit, international agency. A new Aquaculture Stewardship Council certification for farmed fish is also being developed. It is expected to be completed in two years. Standards have already been set for tilapia and Vietnamese catfish.

Jeffrey Hutchings, a biology professor and marine conservation expert at Dalhousie University, says 80 percent of the world's fisheries are "fully fished, overfished or depleted." For example, he says the southern St. Lawrence cod fishery, once the largest source of cod in the world, may be gone in 20 to 40 years.

The move towards more sustainable seafood supplies has been talked about and on-going in one degree or another for quite some time now. I welcome the news that companies such as Loblaws are taking a stance and making concrete moves to reduce the amount of seafood from non sustainable sources.

According to the FAO, "sustainable fisheries and aquaculture means the harvesting and farming of fish stocks in a manner that meets the needs of the present without compromising the ability of future generations to meet their own needs".

Moratorium on Aquaculture Licenses in British Columbia - Will it lead to Benefits ?

An article in the Vancouver Sun Jan 28, 2010 states that B.C. has slapped a moratorium on issuing new finfish aquaculture licences and won't accept new applications for shellfish aquaculture, the province announced Thursday.

The move follows a court decision on Tuesday in which the B.C. Supreme Court granted an extension to the transfer deadline for finfish aquaculture to federal regulation until Dec. 18, 2010. As part of this extension, the court ordered a suspension on approvals of all new marine finfish licenses in B.C.

A related story by Mike Barber of Canwest news service Sept 9 , 2010 titled "Diversity needed on Canada's fish farms, researcher says"

Talks about the Need for Canada to diversify into production of alternative aquaculture species. That article points out that half the fish the world eats is now raised on farms, presenting an opportunity for Canada to exploit a growing global hunger for seafood, according to a study published in the online edition of the Proceedings of the National Academy of Sciences by a team of international researchers.

But critics say Canada is ill-prepared to cash in on the growing trend because of a fixation on farming salmon -- a species that is expensive to raise, takes a long time to grow and is not to the taste of people in the world's rapidly developing markets.

Tony Farrell, one of the report's contributors, said the findings indicate a demand for protein-rich, affordable fish.

"The world is not eating wild fish, and they're switching to cultured fish," said Farrell, chairman of the University of B.C.'s Centre for Aquaculture and Environmental Research. "Canada can either move with the times, or not. As an exporting nation, we need to make decisions about this."

But relying on salmon -- carnivores that take more than two years to mature -- as the country's chief farmed fish would likely prevent the Canadian aquaculture industry from harnessing the continued growth, said Farrell.

"I think diversification is a great way of thinking about this. You put all your stocks and bonds in one thing, and when it crashes, you'll have a rude awakening," Farrell said. Full Story

This blog has always promoted alternative aquaculture systems and the need for further development of other species. While there are many issues effecting the industry two of the main concerns are the potential for environmental conflicts and the need to address sustainable industry growth.

Diversification into alternative farm designs producing other species using sustainable and intregrated methods, is certainly an area that needs attention.

When all the fish are gone?

Here is a great picture and memory:

After a good night’s sleep, you awake to a great sunny morning and reflect upon the wonderful relaxing experience that you enjoyed last night. The memories of that great meal you shared with your special someone rests in your mind. The feeling of comfort and closeness you discovered, over the candle light casting shadows at your secluded table while soft music played, is still fresh in your thoughts.

The seafood was the best choice, it sure made a hit. The succulent flavors blended well with the mood and with the wine, bringing a mutual feeling of pleasure and satisfaction that a good dinner often brings. It was a night to remember, that brought you the same age old enjoyment that good friends, good food and good wine, has done for years. Yes it was great you say. Let us thank the folks that made it possible.

Now Picture this:

You have some slack time and you are wondering around the internet, reading about things that mean something in your life and you are gathering a better understanding of the world. In keeping with your concerns and important issues, the state of the world’s food supply, the quality of food and the price of food are all issues that you read about because you know that they will make an everyday difference in your life. After reading and researching on the subject for awhile you come upon information relating to one of the world’s largest sources of protein and nutritious food, which is fish and seafood.

This maybe is where your bad day starts, as you realize that humankind cannot any longer count on or rely upon wild fish stocks to meet the demands of the future or even satisfy the demands of today.

Perhaps you also wonder where all the fish have gone? If you do, you can also take some satisfaction in knowing that you are not alone. Many of the world’s scientist, governing bodies and think tanks are grappling with the crisis and are searching for alternative ways for making the best of our ocean, river and inland lake fish resources.

It is now written in “factual stones” that the populations of worldwide wild fish and shellfish (stocks) are continuing to be depleted at a rate that surprises even those scientists that made dire predictions a few short years ago. The huge hunting and gathering efforts that has long dominated the World’s supply of seafood are failing. Even with today’s increased overall fishing effort and increased focus upon catching and substituting less desirable fish species, collapse and failure of the wild fishing industry is near, and the lack of sustainability of the fishing effort against available wild supplies is impossible to escape.

Now picture a light:

Once one contemplates the facts and reviews the information it becomes obvious that we should endeavor to do more with what we have and employ a level of husbandry to reduce our reliance upon capture fisheries in the same manner as we reduced our need to hunt and gather other food supplies like grain and animals. Yes I am talking farming.

Fish farming is now supporting over 50% of the entire world’s supply of fish and seafood. The reason for this is very simple, it is the best and most sustainable method to meet the demand that our population creates. Without Aquaculture the wild stocks of fish would have collapsed years ago, as the demand for supply has far outpaced the ability of wild stocks to produce and it has done so for numerous years.

There has been much written of late on the reports of poor populations of many of our fisheries. TAC (total allowable catch) predictions for next year look downright scary. If we continue to ignore solutions to the problem we will continue to have the problem.

If one were to have to "wonder around" today and gather the grains, cereals, poultry, beef and other products needed to ensure survival, it would be a much different world.

In order to meet the demand for high protein foods we have to continue to supplement the available supply by controlled husbandry to help achieve a better yield from a diminishing resource.

Yes we need to continue farming fish and we are learning how to do it much better than before. That learning curve is also called growing, like our plants, animals and fish we have also grown and gained a better understanding of how to do things right, and we will continue to grow and fill the need.

Responsible Aquaculture Program

I spent time lately reading many of the arguments "pro and con" that that seem to pop up when Aquaculture is the topic. Numerous opinions have been expressed and there doesn't appear to be a shortage of media attention in certain areas. That robust activity is welcome. It exists in discussions of any industry or of any practice. As educated consumers we are entitled to review information, decide one way or another and make our choices.

Aquaculture isn’t a new idea, people have practiced Aquaculture for a few thousand years, yet in the modern world today, we still debate just about every news release on the subject. Sometimes we read news statements that are generally based in fact and other statements that contain a few elements of truth designed and emphasized to trigger certain feelings within the population.

Sadly there are a few attention focused presentations within the media that carry very little true research value or census value, and lean toward a more mumble and jumble “argument” that almost always attempts to pigeon hole an industry while presenting the “we told you so attitude” directed at the normal consumer. The reasoning behind this isn’t within my ability to explain.

Last year I wrote a few pages concerning the history and needs satisfied by Aquaculture. In other writings I also talked about the need for improvement.

The Global Aquaculture Alliance efforts to improve the way that Aquaculture is conducted should not go un-noticed.

Statements from the website:

The Responsible Aquaculture Program was developed to promote best management practices for aquaculture operators. The RAP program encourages the culture of safe, wholesome seafood in an environmentally and socially responsible manner. More importantly, it is also intended to improve the efficiency and long-term sustainability of the aquaculture industry.

The Responsible Aquaculture Program began as a straightforward set of "Guiding Principles for Responsible Aquaculture" that promote a cooperative approach to establishing aquaculture operations that reflect environmental, economic, and social sustainability. The principles call for minimal ecological impacts, water conservation, improved feed and drug use, and reductions in effluents.

The Global Aquaculture Alliance is an international, nonprofit trade association dedicated to advancing environmentally and socially responsible aquaculture. GAA recognizes that aquaculture "the culture and farming of fish, shellfish and other aquatic organisms" is the only sustainable means of increasing seafood supply to meet growing food needs.””

Give the link a look.

If we didn’t farm anything period, full stop, where would we be? Can we feed 6 billion people on politics or advertising? Everyday people supply veggies, meats and fish to the world. Managing the resources will play a major factor in the future. Increasing the "food" and ecomonic value of the resources is a factor best left out of media spins.

No Catch Cod is Branded

Sustainable seafood firm adds cod brand
by Jennifer Whitehead Marketing 24 May 2006

LONDON - Johnson Sustainable Seafoods is launching a fresh fish brand called No Catch ...Just Cod, targeting ethically aware, health-conscious shoppers.

No Catch, which will be available in Tesco from 29 May, comes from the world's biggest cod hatchery in Shetland. The fish are fed offcuts of fish already harvested and have no contact with pesticides or dyes.

The packaging, through brand and design consultancy Bryt, is a departure from traditional fish branding and highlights the brand's ethical credentials. The packaging emphasises the product's origins and that it is "tasty, totally natural fish". It adds that it is the world's first organic, sustainable cod and uses the line "Good for you, great for fish".

Although cod is a favourite among consumers, there has been concern about its rapidly diminishing stocks, leading to restrictions on cod fishing in the Irish Sea, North Sea and off West Scotland.

Fish farm forced to close?

David DeKok

One of the larger and more successful commercial fish farms in the northeastern U.S. might be forced to shut down its operations on the Susquehanna River.

PPL Corp. needs to build cooling towers for its power plant at Brunner Island, where Susquehanna Aquaculture also is located. The fish farm thrives because it gets free hot water from PPL. So if the company must move, it cannot remain profitable.

The owner of the fish farm, which sold 400,000 pounds of live striped bass last year to fish markets in the U.S. and Canada, hopes the business can relocate elsewhere on Brunner Island, which is below York Haven and between York and Lancaster counties. But PPL is pessimistic that there is enough space to accommodate both the fish farm and everything else it plans to build on the small island in the next 10 years.

"We don't want to provide any false optimism," said PPL spokesman George Lewis. "We know he wants to stay, but it becomes an issue of not having enough space for everything."

The fish farm opened in May 1989, taking over and expanding a research project PPL had started. Susquehanna Aquaculture uses free hot water discharged from the Brunner Island plant as it makes electricity. The water keeps the stripers warm in their pens year around. By also giving the fish oxygen-rich water and plenty of good feed, the fish grow to full size in a year rather than three years.

It is the only striped bass farm in the Northeast.

Being able to use a heat resource to grow fresh fish at near optinum conditions puts an other wise waste resource to benefical use. I sure hope that they can find a solution and keep growing those stripers. I have eaten their product while visiting Toronto. Very good eating!

Home operated fish farm can make money!

northern aqua farms fish in water logo
I have always been a supporter of small scale aquaculture farms used by family farmers to grow their own fresh fish for personal consumption or for sale. Fish farming can provide additional income to suplement that of an existing agriculture farm or it can be established as a Hobby Type part time business.

Fish farms have been established using ponds or with tank systems constructed in existing builings, greenhouse, garage etc. Some have even been set up in basements. Here's a story about fish operations being successfully set up and ran in the Fort Wayne area to create income.

News Story Snips

JENNI GLENN
The Journal Gazette

FORT WAYNE -- Plenty of country homeowners are looking for ways to make extra cash from their extra acres.

One answer could be to turn a pond or a spare barn into an aquaculture operation. It can take less than $10,000 to start raising fish on a small scale, and the payoff from a side business can add up to $10,000 to $20,000 a year, Purdue University Cooperative Extension Service educators say."""


""Aquaculture businesses can be a variety of sizes, which makes the field a good fit for part-time farmers, said Gonzalee Martin, agriculture and natural resources educator at the Purdue University Extension service's Allen County office. Pendleton Juvenile Correctional Facility in central Indiana spent less than $10,000 to set up an aquaculture operation that raises 5,000 to 10,000 pounds of fish a year, he said.""

Aquaponics Farming is an excellent way to begin growing your own supply of fresh herbs, vegetables and fish year round. A basic simple system can be made at home and consists of a tank of fish connected to one or more growing beds. It can be constructed small enough to fit into a garage, spare room, or kitchen, one or more systems could fit into a shed or home greenhouse. Read more here.

Arctic Char In Sustainable Farming?

picture of high density arctic char farming in tanks
Arctic Char Growing In Tanks
My experiences raising Arctic Char in land based farms using tanks and raceways, with groundwater supplies and water recirculation aquaculture systems, have been positive overall.

I am what you may call a Charr fanatic since the early eighties and most of my experience has been hard won. The road to now has had its share of bumps and even a couple of cliff sized falls. There have fortunately also been some sunny times and even pay days. It has been interesting and rewarding in many ways but also frustrating at times.

I have grown Char at stocking densities that exceed the normal for rainbow trout or salmon in similar farming systems. In a properly designed and operated land based farm, this factor can lead to increased production amounts per unit of rearing space. The high density stocking characteristics of the species can allow the production intensification necessary in controlled systems and provide increased economy of scale, helping to offset the increased costs of building eco-friendly land based fish farms.Full article published at northernaquafarms.com "Arctic Charr Aquaculture - History and Experiences in Canada"
