This Chicago resident envisions fish and plants as central to an accelerator for urban food production.
He hopes his recycled meatpacking factory grows food and supports urban farming pioneers.
A Milwaukee aquapoinics company was recognized this week in the “Energy and Environment” section of the New York Times. Save Water Organics was featured in a story about raising fish while growing water-based plants at the same time. The plants are grown on top of the fishpond. The fish waste supplies the plants with fertilizer, and the plants filter the water for the fish. While the story came out of London, the writer focused on the techniques used at Sweet Water.
Burbot, a native Great Lakes fish species, are slimy, big-mouthed bottom feeders. They’re also threatened in many parts of the world. They’ve recovered in the Great Lakes, but that could mean trouble for plans to restore lake trout.
Three years shy of his family’s 100th year fishing for Lake Michigan whitefish, Paul Jensen rarely meets his quota.
Echo reader Stephanie Ariganello pointed out a typo in Thursday’s Great Links section: “Volunteers sought to protest sturgeon in Michigan – Detroit Free Press”
She writes: “Those pesky sturgeon. We ought to be having rallies against them alright, with their snotty prehistoric scutes and their smarmy shark-like fins. Whether it was a simple mis-typing or subconscious comment on someone’s part, not sure. But I believe it should be ‘protect.’”
It was a simple typo, I swear. We like to be transparent about our biases around Echo. And I feel fairly confident that no one on the staff has it in for sturgeon.
A recent report rates Michigan’s progress in lowering the risk of eating fish as poor.

Which Great Lakes fishery do the Asian carp threaten? The $7 billion one or the $4.5 billion one? Does that include the commercial fishery? What about Canada?
A couple natural resource economists help us settle up.
Mercury and PCBs in Lake St. Clair fish dropped rapidly when polluters closed up shop and dredging removed toxic hotspots.
But fish consumption advisories for the lake won’t be going away any time soon.
Facing an inhospitable habitat, fish have to move or die, says Bryan Pijanowski of Purdue University. “Some of the fish live in aquatic systems that are completely compartmentalized – they’re dammed off,” he says. “So they can’t move.”
A biological balancing act between the premier Great Lakes sportfish and its prey could be at a tipping point in Lake Ontario.
Chinook salmon are the foundation of the Lake Ontario recreational fishery.
