Incentives and Barriers to Adopting Aquaponic and Biofloc Systems in Canada Incentives and Barriers to Adopting Aquaponic and Biofloc Systems in Canada by Hollie Matthews A thesis submitted in conformity with the requirements for the degree of Master of Arts Geography Department University of Toronto © Copyright by Hollie Matthews 2017 Incentives and Barriers to Adopting Aquaponic and Biofloc Systems in Canada Hollie Matthews Master of Arts Department of Geography University of Toronto 2017 Abstract Aquaponic and biofloc systems can contribute to increasing food security while reducing environmental impacts of aquaculture. Other countries are promoting and investing in aquaponics to increase their competiveness in the food and marine sector but there are a limited number of aquaponic and biofloc facilities in Canada. Give the limited research regarding the adoption of commercial aquaponic and biofloc systems, this thesis identifies influences and barriers of implementing biofloc and aquaponic systems in Canada. Through interviews with aquaponic facilities, aquaculture facilities, government officials and biofloc professionals, this research provides insight into the aquaponic and biofloc industry in Canada. This thesis found that there is potential for an increase in both systems in Canada. Adoption of these systems would increase with collaboration and partnership opportunities, examples of profitable systems, increased access to sustainable energy, grants or benefits for creating jobs, grants for implementation and support for sustainable initiatives. ii Acknowledgments First I would like to thank my supervisor, Professor Harvey Shear, for being encouraging and supportive throughout my Master’s degree. I am truly grateful to have had his consistent guidance and support. I am also grateful for Professor Kathi Wilson for her insight and encouragement throughout my thesis process. I would like to thank Professor Andrea Olive and Professor Kathi Wilson, my committee members, for being supportive of my research and providing insightful feedback. I would like to acknowledge and thank all the participants that gave their time to speak with me. I greatly appreciate that each participant took time out of their busy lives to contribute and support my research.

  • SUSTAINABLE FISHERIES and RESPONSIBLE AQUACULTURE: a Guide for USAID Staff and Partners
    SUSTAINABLE FISHERIES AND RESPONSIBLE AQUACULTURE: A Guide for USAID Staff and Partners June 2013 ABOUT THIS GUIDE GOAL This guide provides basic information on how to design programs to reform capture fisheries (also referred to as “wild” fisheries) and aquaculture sectors to ensure sound and effective development, environmental sustainability, economic profitability, and social responsibility. To achieve these objectives, this document focuses on ways to reduce the threats to biodiversity and ecosystem productivity through improved governance and more integrated planning and management practices. In the face of food insecurity, global climate change, and increasing population pressures, it is imperative that development programs help to maintain ecosystem resilience and the multiple goods and services that ecosystems provide. Conserving biodiversity and ecosystem functions are central to maintaining ecosystem integrity, health, and productivity. The intent of the guide is not to suggest that fisheries and aquaculture are interchangeable: these sectors are unique although linked. The world cannot afford to neglect global fisheries and expect aquaculture to fill that void. Global food security will not be achievable without reversing the decline of fisheries, restoring fisheries productivity, and moving towards more environmentally friendly and responsible aquaculture. There is a need for reform in both fisheries and aquaculture to reduce their environmental and social impacts. USAID’s experience has shown that well-designed programs can reform capture fisheries management, reducing threats to biodiversity while leading to increased productivity, incomes, and livelihoods. Agency programs have focused on an ecosystem-based approach to management in conjunction with improved governance, secure tenure and access to resources, and the application of modern management practices.

  • FAO Fisheries & Aquaculture
    Food and Agriculture Organization of the United Nations Fisheries and for a world without hunger Aquaculture Department Fishing Techniques Midwater Pair Trawling Main Components Aquatic species Target Species Semi-pelagic/demersal species Atlantic herring European pilchard(=Sardine) Seabream Hake Seabass European sprat Target Species Pelagic species Gear types: Midwater pair trawls Midwater pair trawls It has similar characteristics as midwater trawls used with otter boards. Vessel types: Pair trawlers In the wet-fish trawler the fish is kept in the hold in the fresh/"wet" condition. Characteristics Midwater pair trawling Species Environment Midwater pair trawling can be effective in different situations: when fish are aggregated into large dense shoals and when (at another season or time of the day or according to physiological status) fishes are regularly distributed within a given water layer. In addition to the difference it makes whether the FAO Fisheries and Aquaculture Department fish are aggregated in a small volume or spread within a large one, fish may swim (and avoid the net) at different speeds according to its own physiological status and/or other external conditions. As a result, in addition to the fish which is targeted, other different conditions will affect the design and size of the midwater trawl, as well as the towing speed. Fishing Gear A midwater pair trawl has roughly similar design as other midwater trawls. Midwater pair trawls might, however, be designed to have a more rectangular opening than ordinary midwater otter trawls. Midwater pair trawls might be rigged with two towing warps from each vessel or alternatively with one towing warp from each vessel and a bridle arrangement.

  • What Is a Bottom Trawl?
    What is a Bottom Trawl? Bottom trawls are a type of mobile fishing gear consisting of very large nets that are dragged on the seafloor to catch groundfish and other species. Bottom trawls are used in virtually all East Coast, West Coast and Alaska fisheries to catch shrimp and fish such as cod, flounder and rockfish. Trawls are used from shallow, inshore depths of 50-feet to extreme depths of 6,000-feet on the continental slope. The National Academy of Sciences found in its 2002 report, “Effects of Trawling and Dredging on Seafloor Habitats,” that U.S. trawlers have damaged over 230,000 square nautical miles of seafloor, an area greater than California. The most common type of bottom trawl in the United States is the otter trawl, in which the net is held open vertically by the force of water moving against two massive otter doors/boards. The trawl net can stretch 40-feet in height and spread over 200 feet wide between the doors, depending on factors such as the depth fished and the type of fish targeted. A large, fully-rigged net weighs well over a ton and requires a large, powerful boat to drag the net, particularly when loaded with a catch of hundreds or thousands of pounds of fish and bycatch (unwanted, non-target species) in the codend, or back of the net. The impact to the seafloor from trawling is a compound of the weight of the net and the forward momentum of the gear as it is dragged forward. The opening of a bottom trawl net is lined with floats on the headrope and with weighted ground gear on the footrope.

  • The Role of Sustainable Fisheries and Aquaculture for Food Security and Nutrition
    The Role of Sustainable Fisheries and Aquaculture for Food Security and Nutrition James Rohan CPA MBA WorldFish, FAO and World Resources Institute has conducted research recently which will support many of the questions suggested. Principles of sustainable business should be considered as the framework seeks to have minimal negative impact on the global or local environment, community, society, or economy,while achieving an industrious objective. Local environment will require an understanding of marine life and a model similar to planetary boundaries may promote education, research opportunities and continuous improvement principles. Many of the researchers have commented on the lack of research activity in this area and justifies the request by FSN for consideration. Rather than calories, I have proposed in the past a nutritional mass balance approach to recognise nutrition for health in food security. This would require consideration of yield and while some researchers have identified process capability, we should also explore product capability. Is nutrition compromised under stress or can it be enhanced with management? Over 90% of the world's living biomass is contained in the oceans, which cover 71% of the Earth's surface. At present, we harvest about 0.2% of marine production. ● Marine sources provide about 20% of the animal protein eaten by humans. Another 5% is provided indirectly via livestock fed with fish. ● 60% of fish consumption is by the developing world. ● The fishing enterprise employs some 200 million people worldwide. http://www.globalchange.umich.edu/globalchange2/current/lectures/fisheries/fisheries.html Data exists which suggests some fisheries are over and under exploited.

    Meeting: Wageningen and EFARO on the Green Deal, Farm to Fork and Food from the Oceans 22.1.21 10.00 – 12.00 by webex Welcome from Luc van Hoof, Executive Secretary of EFARO Luc welcomed over 40 participants and experts who had joined to discuss circular food production in our oceans. Start with Professor Louise Fresco, Chair of EFARO: Changing philosophy about changing production and how we see the sea In the least 10-15 years we’ve seen a slow and gradual change in the philosophy on the use of natural resources for food + feed. Concepts like biobased, local, circular have all come into place. It’s pushed by growing distance between urban consumers and the realities of how production and use of resources takes place. There’s also impetus from the Paris agreement, the need to be more carbon neutral, and nature conservation is a goal in itself. This has led to a political shift, e.g. the Green Deal. It’s our task to provide a scientific basis for it. The idea of circularity is complicated. And there are issues of carbon neutrality and positivity (carbon fixing). The overall thing is that this is about quality not quantity. What is circularity: Waste from one trophic level becomes used for another trophic level - resource use efficiency. It also means nutrient efficiency (nitrogen, phosphates etc). Try to develop a more integrated perspective of land based and marine based sources of nutrients. What is the optimal protein base and how to get best proteins for our food? So it’s the whole world of biobased economy.
