In an age of biotechnological juicing, not even the easygoing pastime of fishing is free from controversies over artificial enhancement.

On September 5, Saskatchewan fisherman Sean Konrad caught a 48-pound, world-record rainbow trout. The fish came from Lake Diefenbaker, where trout genetically engineered to grow extra-big escaped from a fish farm nine years ago.

The previous world record was held by Sean’s twin brother Adam, who pulled a 43-pound, 10-ounce rainbow trout from Lake Diefenbaker in 2007. That catch sparked online debate over the legitimacy of Lake Diefenbaker’s farm-born, genetically-engineered rainbows. Technically known as triploids, they’re designed with three sets of chromosomes, making them sterile and channeling energies normally spent reproducing towards growth.

In 2007, on a message board of the International Game Fish Association, the angling world’s record- and ethics-keeping body, some fishermen argued that triploids were unnatural, as divorced from the sport’s history as Barry Bonds’ home runs were from Hank Aaron’s.

The IGFA refused to make a distinction between natural and GM fish. Neither would they distinguish between species caught in their traditional waters and those introduced into new, growth-friendly environments, such as largemouth bass whose extra-large ancestors were imported from Florida to California in the 1960s.

But to purists, there was a difference between transplantation and outright manufacture.

The Konrad brothers’ response on the message board was curt: “Stop crying and start fishing.”

Now they’ve caught another record-breaking trout. Or have they?

Record brown trout caught in Manistee

Definitely a state record, could be a world record

The Ludington Daily News has learned that what appears to be a new world record brown trout was caught in the Manistee River this morning.

Grand Rapids area resident Tom Healy caught the 41-pound, 7.25 ounce monster on a crankbait while fishing with Tim Roller’s charter service. Michigan DNR fisheries biologists Mark Tonello and Todd Kalish weighed the fish after leveling the certified scales and determined the weight. It is the new record hold for Michigan. Upon the second weighing with the scales leveled, the weight was determined to be 1 pound, .75 ounces heavier than originally determined. The fish was 43.75 inches long.

The fish is 1 pound, 3.25 ounces heavier than the reigning world record German brown trout, a 40-pound, 4-ounce fish caught in Arkansas in 1992 by Howard “Rip” Collins who used an ultralight rod and 4-pound test line to catch that fish. Healy will have to apply for certification to be declared the world record holder.

The state record German brown trout until today weighed 36.81 pounds and was caught in Lake Michigan in Benzie County in 2007. The next three places in the state record books were held by Lake Michigan browns caught in Manistee.
