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.

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.

Global Aquaculture Outlook 2010


Global Conference on Aquaculture 2010 - FAO publication releases.

The Fisheries and Aquaculture Department of FAO published seven technical documents on aquaculture which are of global relevance. These documents can be found at this link.

The FAO states that these Regional Reviews and the Global Synthesis can be of pertinent use to national governments, regional organizations, policy makers, farmers, investors, civil society organizations, research and training institutions and the general public.

I, like many others, am busy reading these publications in my spare time and hoping to gain some helpful insights and fresh data from the reports. 

From my limited review of the 2010 publications to date; one thing that certainly stands out is that the industry continues to grow based on need and demand for sustainable fish supplies by the world population. Here is a quote from “State of world aquaculture 2010"

Global production of fish from aquaculture has grown substantially in the past decade, reaching 52.5 million tonnes in 2008, compared with 32.4 million tonnes in 2000. Aquaculture continues to be the fastest-growing animal food producing sector and currently accounts for nearly half (45.6 percent) of the world’s food fish consumption, compared with 33.8 percent in 2000. With stagnating global capture fishery production and an increasing population, aquaculture is perceived as having the greatest potential to produce more fish in the future to meet the growing demand for safe and quality aquatic food.
According to FAO, it is estimated that by 2012 more than 50 percent of global food fish consumption will originate from aquaculture.


With all this fresh data and some review time I hope to make more posts and comments on the state of affairs. I hope that you do also, feel free to comment here.

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!

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.

Aquaculture sees surge in worldwide production

A new report by an international team of researchers, published September 07 in the online edition of The Proceedings of the National Academy of Sciences (PNAS), states that Aquaculture now accounts for 50 percent of the fish consumed globally.

Once considered to be a fledgling industry not so long ago, "Aquaculture is set to reach a landmark in 2009, supplying half of the total fish and shellfish for human consumption," the authors wrote.

Way back when, 20 or so years ago, I entered the field of aquaculture after witnessing first hand the ever increasing year to year decline in the traditional fishing industry. Back then we all felt to be on the verge of something new and big, today we can look back and see just how far the industry has come. The growth has been tremendous but it has certainly not been without challenges.

The report states that between 1995 and 2007, global production of farmed fish nearly tripled in volume, in part because of rising consumer demand for long-chain omega-3 fatty acids. Oily fish, such as salmon, are a major source of these omega-3s, which are effective in reducing the risk of cardiovascular disease, according to the National Institutes of Health.

This growth has placed ever increasing pressure on marine resources due to the need for large amounts of feed made from wild fish harvested from the sea. "The huge expansion is being driven by demand," said lead author Rosamond L. Naylor, a professor of environmental Earth system science at Stanford University and director of the Stanford Program on Food Security and the Environment. "As long as we are a health-conscious population trying to get our most healthy oils from fish, we are going to be demanding more of aquaculture and putting a lot of pressure on marine fisheries to meet that need." Sourcing sustainable feed ingredients is one of the largest challenges faced by the industry today.

One way to make salmon farming more environmentally sustainable is to simply lower the amount of fish oil in the salmon's diet. According to the authors, a mere 4 percent reduction in fish oil would significantly reduce the amount of wild fish needed to produce 1 pound of salmon from 5 pounds to just 3.9 pounds. In contrast, reducing fishmeal use by 4 percent would have very little environmental impact, they said.

"Reducing the amount of fish oil in the salmon's diet definitely gets you a lot more bang for the buck than reducing the amount of fishmeal," Naylor said. "Our thirst for long-chain omega-3 oils will continue to put a lot of strain on marine ecosystems, unless we develop commercially viable alternatives soon."

Naylor and her co-authors pointed to several fish-feed substitutes currently being investigated, including protein made from grain and livestock byproducts, and long-chain omega-3 oils extracted from single-cell microorganisms and genetically modified land plants. "With appropriate economic and regulatory incentives, the transition toward alternative feedstuffs could accelerate, paving the way for a consensus that aquaculture is aiding the ocean, not depleting it," the authors wrote.

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.

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.

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"
