As of today, I have officially completed the MSc. program in Sustainable Aquaculture Business Management at the Institute of Aquaculture, University of Stirling. My dissertation manuscript on aquaculture stock mortality insurance was submitted several weeks ago, and just this week I gave a presentation and had my oral defense. Everything went very smoothly, and now the program is officially over!
I have returned to Vancouver, British Columbia where I am currently seeking employment in the aquaculture sector. As my adventures continue, and as new and interesting aquaculture technologies and developments come to light, I will update this blog accordingly. Also, please feel free to comment on the articles and use this blog as a forum for the sharing of ideas and constructive discussion- only through increased communication, education, and awareness can we propagate changes towards sustainability in the global aquaculture industry.
This blog chronicles my adventures and experiences in fish farming, as well as explores future directions towards sustainability. Ultimately, aquaculture is a necessary industry, and it is important that we work to establish a field that is both environmentally-friendly and economically-viable for generations to come.

Danish Company Launches Commercial Recirc Salmon Farm
Danish company 'Langsand Laks' has begun production at what they call the “world’s first commercial landbased Atlantic salmon farm”. Growing Atlantic salmon in Recirculating Aquaculture Systems (RAS) is known to be a veritable ‘Holy Grail’ within the aquaculture industry: salmon is a high value product, and it grows exceedingly well in marine net cages, but the environmental impact is significant. RAS has been identified as a more sustainable production system, utilizing treatment and recycling of the water instead of discharging it into the environment. Restrictions have arisen based on the economics of RAS systems: they are extremely expensive to build and operate, plus a great deal of knowledge and expertise is required in the areas of engineering, hydrodynamics, fish health and biology, and waste management. With an initial production of 1,000 tonnes per year, this Danish facility will be vital pilot study into the economic feasibility of on-land, recirculation salmon production.

The Debate over Land-Based Salmon Farms
Currently, there is a very strong debate in British Columbia regarding land-based salmon farms: if this technology exists, why isn’t the industry adopting it? On-land recirculation systems separate farmed salmon from the natural environment, thus removing any potentially harmful environmental effects that may stem from open net-cages. Wastes from the farmed fish can be collected and treated rather than being released into the marine ecosystem. Additionally, any diseases or parasites can be screened for and monitored much more closely, thus protecting both the farmed stock as well as the wild fauna.
However, there are several key points that must be addressed in this debate. The first is that land-based systems are extremely expensive, both to build and to operate. By their very nature, a land-based recirculation system is much more capital-intensive to set up than a net-pen operation: tanks, pipes, pumps, filters, the land itself, a building if necessary...these are all costs that net-pen operations do not have to cope with. Add into the equation the cost of electricity and the overall carbon footprint of the facility, and suddenly land-based systems are not looking as attractive.
There is a fantastic report by Fisheries and Oceans Canada (2010) that states that while land-based recirculation systems may be economically viable, their high operating costs make them extremely sensitive to fluctuations in market conditions (the price of salmon, the price of electricity/water, etc.): the margins are so small that a tiny shift in the market may be all that is necessary for the system to lose its profitability.
That report is available here: http://www.dfo-mpo.gc.ca/aquaculture/lib-bib/nasapi-inpasa/BC-aquaculture-CB-eng.htm#7
While it may not be possible for the salmon industry in BC to adopt these systems immediately, there is hope on the horizon. As I write this, researchers and engineers are working hard to continue developing these technologies with the sole purpose of increasing efficiency and decreasing operating costs. Additionally, by implementing other sustainable farming methods (aquaponics, solar/wind power, etc.) the operating costs can be reduced even further.
It is my opinion that these systems are inherently better than the current practices, but unfortunately we are simply not yet prepared to adopt them.

Aquaponics Makes a Splash at TED Talks
A few weeks ago, a staff member from the Institute of Aquaculture gave a fantastic presentation on aquaponics at an independently-organized ‘TED’ event in England. As you may know, TED events consist of short 20-minute seminars given by experts in a number of fields, but presented in a way so as to be accessible and understandable to everyone. Businesspeople, scientists, artists, you name it...every speaker has an innovative topic and the presentations are always interesting!
Charlie Price is one of the founding members of Aquaponics UK, a social enterprise that works as a consulting firm for aquaponics projects around the globe. Before deciding to do my MSc dissertation on aquaculture insurance, I was in talks with Charlie to join his team for my dissertation work!
Charlie’s TED Talk covers the basics of aquaponics and explains how a well-designed system operates exactly like a natural ecosystem, with the wastes being recycled and used by other organisms. He then walks through a facility that his company designed and built in London- fish, chickens, plants, and even flies are all cultivated together in a harmonious environment that people can actually visit and learn more about!
Aquaponics is a reliable and versatile way to significantly reduce the impacts that aquaculture has on the environment. And as Charlie describes, as you include more species in the system, it becomes cleaner, more productive, more efficient, and ultimately more profitable!

Aquaculture Insurance MSc Dissertation
My MSc dissertation focuses on aquaculture stock mortality insurance in the United Kingdom and Ireland, working to identify the attitudes and perceptions that fish farmers have regarding this specialized product. This study will provide a bridge between fish farmers and insurance companies to identify the accessibility and appropriateness of currently available stock mortality insurance policies. It is expected that the conclusions of this study will help increase the suitability and value of future stock mortality products.
There is a short on-line questionnaire to be completed by fish farmers: it will take less than 15 minutes to fill out. The questionnaire is available at the following website:
