Our Vision 

To address, and raise awareness about, issues and concerns regarding our current and future food supply; promote sustainable and healthy alternatives for food production and supply; engage individuals in actively exploring alternatives; serve as an “agitator” for change in food-related systems.

Our Mission

To create a working aquaponics model and year-round food production system that can be replicated to promote and engage communities in local, sustainable food production.

Pat and I initiated the Port Washington Aquaponics Model in March of 2009. Our interest in local sustainable food production, however, developed over time – and only in the last few years has it taken on a more urgent tone.

Pat and I come from very different food “histories.” His includes a very large family garden, necessary to feed a family with 8 children. His mother stretched and used everything in creative ways. This included okra, not one of Pat’s favorite vegetables to this day (and he can only eat spinach in certain ways). Pat’s memories include being assigned a row in the garden to take care of.  Punishment also included going to the garden to weed. Canning was an annual event to supplement winter menus. My history is like many my age – we were a city family growing up in the 50’s. My food memories include meals from cans and boxes. Cream of mushroom soup had a million uses, and a treat was a TV dinner.

In 2006, we were introduced to Community Supported Agriculture (CSA). We signed on to receive fresh vegetables from Wellspring Farm in Newburg, WI. I couldn’t name most of the vegetables we received in the first year. I also had no sense of the growing season. We continue to buy shares from Wellspring and have learned how to cook “root” vegetables and anticipate the lettuces we receive early in the season, and the black radishes, celeriac, and squash that come later.

But, our commitment to doing something about food grew out of a Menu for the Future discussion course. Menu for the Future was developed and sponsored by the Northwest Earth Institute in Portland, Oregon. Pat and I met with friends, weekly, for eight weeks, hosting our group in our homes. We read articles, talked about our food histories, our concerns about food, the environment, and sustaining healthy lifestyle options for our children. At the last meeting, the question posed was, “What do we do next?”

Pat took this question very seriously. His first idea was to develop a local food council. We had read about food councils and ways in which a council could help to focus communities on local food, sustainable production practices, and to serve as a catalyst to creating local food options.

While the group didn’t settle on this idea, it did decide to visit a local food operation in Milwaukee; Growing Power. Growing Power was receiving a lot of attention, locally and nationally.  According to its website, Growing Power “is a national nonprofit organization and land trust supporting people from diverse backgrounds, and the environments in which they live, by helping to provide equal access to healthy, high-quality, safe and affordable food for people in all communities.”

Growing Power’s founder and director, Will Allen, attributed his growing success to worms. He has perfected growing worms as an organic medium for growing plants. He also has developed quite a composting system that heats hoop houses, sustaining a growing season through the winter. But, the project that most intrigued Pat was raising fish. Growing Power raises tilapia using an aquaponics system. Aquaponics is a system that cultivates plants and fish in a recirculating system. It is a combination of aquaculture and hydroponics.

What is the advantages of such a system to food production? It’s local, it is safe, and it is sustainable. A closed system continuously moves water from the fish to the plants. The plants take up the nutrients provided by the fish waste and sends clean(er) water back to the fish environment – the cycle continues. The system relies on a natural relationship that maintains an environment that supports the fish and the plants.

Our interest in aquaponics as a means of supporting local and sustainable food production grew as we continued our research into food, food production, distribution, and the industrialized food system that has developed since World War II.  Some facts that convinced us that investing time and money in aquaponics and local food production was important:

  • Less that 1% of food is local; on average, food travels 1,500 miles;
  • Most people, saddest of all children, do not know or pay attention to where their food comes from;
  • Current large scale industrial farming depends heavily on petroleum products for planting, harvesting and distributing;
  • Food safety is at stake, with chemical fertilizers and pesticides that degrade farmland and waterways;
  • There are growing concerns about access to safe food sources, particularly protein-based foods;
  • There are increased use of additives and genetically modified foods in processed food;
  • There is an increase in obesity, illnesses, and diseases that can be attributed to poor diets and limited access to healthy food alternatives.

Pat and I started our aquaponics model with simple fish aquariums. An ad in the local paper netted us multiple 50-75 gallon fish aquariums from individuals who had had enough of raising tropical fish in their homes as a hobby. These aquariums were the basis for our first model – Model I. We are now developing Model III. We see our models developing, changing, and growing all the time. We’ll keep you posted!
