The idea failed to catch on among the trout farming sector.
Following a successful trial by a local trout farmer, Tuerk – who had moved to a career in water quality – was poised to roll out his novel design to farmers in the Great Lakes and beyond. “The four spars are connected by a walkway making it similar to operate, when on the surface, to regular pens, but no net weights are needed which is nice, especially in areas with high currents, as the cage provides attachment points to pull the net down and across to keep it tight in heavy currents,” he says.By 2004, four years after coming up with the concept, the first of his cages was ready.
Jeff Tuerk designed and built his own submersible cage and is now looking for funding to build another one He decided on building a four-spar steel submersible cage with a 2,600m 3 capacity, which could be raised and lowered to the desired depth using nothing more sophisticated than a compressor. There are no storms, no waves, no ice, no predatory birds and a better temperature regime,” reflects Tuerk. There’s nothing to see, so people don’t complain. But it’s even more comforting when you sink it – you can go home at night and never have to worry. When it’s at the surface the wave energy passes right through it with no issues. “Why be at the surface with all this turmoil and these issues? The conditions are much more favourable in deeper water. With windchill driving winter temperatures below minus 40☏ on a regular basis and ice covering the lake for six months of the year it’s a tough environment – both for farmers and their fish.Īfter 10 years on a rainbow trout farm in Manitoulin Island, Ontario, Jeff Tuerk decided there must be a better way to farm than the standard net pens used in trout production and decided to design, and build, a submersible alternative. Farming fish on Lake Huron isn’t for everyone.
