Arctic Char In Aquaculture

Arctic Char were first investigated as an aquaculture species because it was expected that they would have low optimum temperature requirements and would grow well at the cold water temperatures present in numerous areas of Canada. It was also "correctly" anticipated that the Arctic Char would be welcomed as an alternate selection to Rainbow Trout and thus could provide producers with a unique product and a niche in seafood markets.


Canadian Arctic char are farmed in the Yukon Territory, Nova Scotia, and New Brunswick, Quebec and Manitoba. Operators in Iceland, Norway and the USA also raise Char. There are several different strains of Arctic Char being used in aquaculture. The most common strains used in Canada are derived from Nayuk Lake and Fraser River stocks.

Good Aquaculture Attributes

The majority of Arctic char produced today are raised in land-based systems. Arctic char eggs are hatched within specialized hatchery facilities where the young fish remain until they reach ~100 grams and can be transferred to larger grow - out tanks. The initial early rearing stages of growing can take almost a year for the juveniles to reach 100 grams. Once in the production farm Arctic char exhibit a rapid growth spurt from juvenile to adulthood, with most stocks reaching market weight (1-2.5kg) within the next 12 months.

Well Suited to Land Based Aquaculture

Land-based Arctic char rearing systems are considered to be among the most environmentally responsible fish farming designs. Facilities that utilize designs based on the principles of Recirculation Aquaculture technologies are among the most cutting edge farms. Arctic Char exhibit unique characteristics that make the species favorable to land based secure production, chief among those is its natural desire to shoal and live in high density populations.

Excellent Market Reception

The Arctic Char is highlighted as a “Best” choice by the Monterey Aquarium Seafood Watch Guide for Healthy Oceans. The New England Aquarium lists farm raised Arctic Char as an ocean friendly species. They call it an excellent choice. Read more here

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.

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.

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.

Realted Items: Land based Fish Farms | Aquaponics Technologies

Waste to green or ruin

Over 3000 years ago peoples in Asia began to practice poly culture, a process development in which they successfully learned how to recycle agriculture wastes to improve the yield obtained by farming a secondary source of protein( yet eventually equally or more important than the initial crop), that protein source was fish.

Now let us go further back in an effort to explore the role of fish as a part of the diet:

Fish and shellfish have been part of the European’s diet for as long as man has been present on the continent. Indeed, 500 thousand years ago, Homo erectus would have caught salmon (probably by hand) and eaten it raw, perhaps accompanied by a few berries and nuts. Today, salmon carpaccio bears a distinct resemblance to such paleolithic gastronomy (first age of prehistory, till 10 000 BC) .

Mesolithic man (between 10 000 and 5 000 BC) appreciated oysters and mussels while fish would have long been established as a highly desirable food. As farming activities developed, man also became able to master the rearing of animals and the same concepts were applied to fish. Reference link: http://www.feap.info/home/FAQ/Answers/ans1_en.asp

The first Publication of "Fish Husbandry", written by Fan Li, was made around 500 BC and it documented a farming process that was in practice (and still in practice) many years before our well accepted and present day world beliefs and preceptions.

Poly culture back then, simply involved using organic waste to naturally produce feed to fertilize plants that the fish ate and converted into a high protein source (Fish) for humans to consume. The Fish waste also became another source of organic food to nourish other plants and vegetables, thus increasing the yield and variety of edible food obtained.

These farming practices were very `green` back when they were invented and practiced. Considering that the inputs and outputs balanced each other without diminishing other resources or relying on such things as inorganic ingredients, the process is very simple and sustainable.

Today, such a process of farming is pretty much considered in the same light as one eyed aliens visiting the earth. There is no big company that is mass producing by using the farming principal, thus it is insignificant and perhaps a topic of dis-flavour in the circles of corporate agriculture .

Perhaps if more people grew fish and fresh vegetables on their own with little or no cost, it could be a real part of being green.

For the most part such practices are in Ruin today.

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.

Home operated fish farm can make money!

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.

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.
