Fish stories

I reported on Friday that angler Jarrett Knize caught a 34 kg carp in the Humboldt Park Lagoon earlier this month. Block Club Chicago explains how the Fish of Unusual Size might have wound up there:

As for how the carp got there in the first place, Kevin Irons, assistant chief of fisheries for the Illinois Department of Natural Resources, has a theory.

Irons, who managed the department’s carp program for a decade, said carp were accidentally introduced to the lagoon about 20 years ago. When a state-contracted fish hauler dumped a bunch of game fish in the lagoon for urban anglers like Knize, some carp found their way into the batch, he said.

Although it hasn’t been confirmed yet, officials think Knize caught one of those 20-year-old carp, Irons said. The department is still evaluating the fish, so its age hasn’t been confirmed.

Though carp are highly invasive, Knize’s catch doesn’t spell trouble for the lagoon, Irons said. A few carp won’t harm the lagoon — or any other ponds, for that matter — because carp only reproduce in flowing bodies of water like the Illinois River, he said.

That's still one hell of a goldfish.

    I'm reminded of a population of tropical fish that were reputed to live in a stretch of canal in St Helens, a town in northern England close to where I grew up.  This stretch of canal was known locally as "The Hotties" because it was warmed by a constant outflow of cooling water from the adjacent Pilkington plate-glass factory.  On cold days, the water was warm enough that steam would rise from it.  Local lore said that people had dumped unwanted tropical fish in it, and they had not only survived, but thrived.  It was very popular with anglers.
