Researchers Reveal Why Muskies Are So Hard to Catch

Should you ever hear a Midwesterner point out the “fish of 10,000 casts,” you may be certain they’re speaking about muskies. Each area in North America has its personal fish species that represents the top of angling prowess, from allow within the Florida Keys to steelhead within the Pacific Northwest. These fish are nearly all the time on the bigger and rarer aspect of the spectrum, which is a part of why they’ve turn into shrouded in thriller and idolized by anglers through the years. That is very true of muskies, therefore the nickname. However why are muskies so exhausting to catch?

A staff of researchers on the College of Illinois just lately got here up with some definitive, science-based solutions to that age-old query. They did this by finding out a bunch of muskies in a laboratory setting after which fishing for them for 35 days straight in a managed setting. Their outcomes have been revealed within the North American Journal of Fisheries Management.   

How Researchers Examined Their Theories

This scientific inquiry into why muskies are referred to as the fish of 10,000 casts was led by College of Illinois graduate pupil John Bieber together with Bieber’s advisor, Dr. Cory Suski. Dr. Suski explains that the thought behind the experiment got here from the Illinois Department of Natural Resources, which raises muskies in hatcheries and releases them in water our bodies throughout the state. The DNR had been conducting netting surveys at one specific lake, and after seeing the sheer variety of muskies that lived there, they have been curious why catch charges weren’t larger.

So, the company loaned 68 hatchery-raised muskies to Bieber and Suski, who spent the following a number of weeks finding out these fish in a laboratory setting. Every fish was individually microchipped and positioned in a tank, the place the researchers ran experiments 4 fundamental behavioral traits: exercise, aggression, boldness, and exploration.

“Fish do have personalities,” Suski explains, “identical to different animals and folks.”

After gauging and recording every muskie’s character, the researchers then took the 68 fish and stocked them in an experimental pond. The pond was emptied of different aquatic species beforehand, they usually crammed it with minnows so that every one the muskies have been content material and equally well-fed.

Then got here the enjoyable half. Bieber and Suski fished the experimental pond with typical gear for 35 days straight. They coated each inch of water utilizing each mixture of lure and presentation they might consider. On the finish of the 35 days, that they had caught seven fish.

Suski says the largest takeaway from the experiment was that sure muskies have been extra “predisposed to seize” based mostly on their character traits. He explains that general, the fish they caught have been bigger, much less exploratory, and fewer aggressive than the others. This additionally falls according to the species’ general feeding habits. As solitary apex predators, muskies prefer to patiently lie in wait after which ambush their prey instantly.   

“They only desire to dwell beneath a log by themselves,” Suski says. “We’ve got to principally hunt for them and hit them within the face with a lure. And we are likely to solely hook them once they’re sitting nonetheless and quiet and are able to clobber one thing.”

One other attention-grabbing lesson that the majority hardcore muskie anglers would echo is that muskies are extraordinarily delicate to angling stress. Out of the seven fish that have been landed over a 35-day interval, 4 of them have been caught in the course of the first day of fishing. The muskies grew to become much less receptive to lures in every week that adopted. Suski and Bieber by no means hooked multiple fish per day after that, and most days they walked away from the pond skunked.

Not one of the fish have been caught greater than as soon as, both, which reinforces the concept muskies smarten up and shut off fairly rapidly when lures begin flying of their route.

“They wizen up for certain,” Suski says. “There may very well be a bunch of various issues happening there, and the literature would say it’s the ‘noise of the angler’ they’re responding to. However [muskies] undoubtedly turn into extra cautious and fewer receptive when pressured.”

Suski provides that the largest takeaway for the DNR is that catch-and-release practices are important to a powerful muskie fishery. The concept right here is that if some muskies are virtually uncatchable, whereas others have personalities that make them extra vulnerable to seize, anglers could have extra success within the long-term in the event that they launch the catchable fish again into the breeding inhabitants.

“Should you catch a fish that has the precise mixture of character traits to hit your lure, be mild with it and put it again,” Suski says. “As a result of hopefully that fish will proceed to have infants, and we are able to hold these susceptible character varieties within the inhabitants for longer.”
