Are the Muskies You See Really That Big?

Muskies underwater are only 3/4 of the size they appear.  (c)Eric Engbretson

One of my favorite websites for fishing information is Lake Link. The fishing reports posted on this site by the thousands of fisherman who fish the many lakes in the Midwest region can be useful, informative and entertaining. While some of the most experienced and knowledgeable fisherman post fishing reports and their observations while on the water, I am constantly amazed at one glaring mistake so many fisherman make. That error is not understanding the magnifying effects of water. Simply put-fish look bigger under water than they really are. The message boards on Lake Link are filled with hundreds of eye-witness accounts of fisherman reporting large muskies that "swam right next to the boat that were 50 inches!" Could there really be that many 50 inch muskies swimming around? The answer is a disappointing "No".  What these fisherman all fail to realize is that fish in water, viewed through air are only 3/4 of the size they appear to be. So, all those mammoth 50 inch fish are really just ordinary 37.5 inch long muskies.

Scuba divers all understand that one attribute of water is that when viewed through a prism of air, also known as a diver's mask, objects appear much larger than they really are. Underwater, a 45 inch musky will look a 60 inch whopper! Fisherman often ask me how large the fish are that I see underwater. Honestly, most fish look big underwater, and big fish look like Godzilla. In my early days of diving I was convinced that each musky I encountered was a world record.  Many scuba dives later, I've come to better understand the illusion, and realize that reports of monster muskie that "got off just as they were about to be netted" were likely ordinary sized fish.

Some may argue that the fish lined up exactly with something on the boat that's of known size and reference, but the viewer doesn't understand the illusion facing scuba divers all the time. Boats and the objects on them are poor comparison tools as they're in the atmosphere, visually accurate in size, while the musky is underwater, distorted in size. To test this concept yourself, measure your hand. Then lean over the side of a fishing boat or dock and stick it about a foot underwater. Hold the ruler above the surface while viewing your submersed hand, and measure it best you can. How'd the numbers come out? If you did this correctly, your dry hand will be roughly ¾ the underwater hand size.

While the fishing reports on websites like Lake Link can be valuable research tools, don't be fooled by eye-witness accounts of large fish that were seen underwater. They just weren't that big.

The Wonderful World of Walleyes: Underwater Video



We’re getting some great walleye video in 2017.  Here’s a compilation of some of the remarkable underwater footage we’ve collected so far this summer.  Straight from the depths of Wisconsin’s northern lakes, see crystal-clear underwater video in HD of walleyes where they live.  Abundant crayfish, rock piles, sunken timber, and other habitat elements attract walleyes like magic as they pose for our cameras in their watery homes.  Thirty seconds of walleyes up close in incredible clarity and awesome fidelity.

Northern Pike Underwater Photos

Our Paul Vecsei has been busy shooting some beautiful new pictures of Northern Pike.  As Paul describes it, "The key (to photographing pike underwater) is what I call the polite pursuit, where an individual is chosen and followed. If the Pike wants nothing to do with me, it can lose me in a second. But some just keep a short distance and eventually allow me to approach. Once the camera with its large dome port is put close enough, I have him. They become mesmerized by their own reflection."

Why Underwater Fish Photos Are Important

In the December '09 issue of Fisheries MagazineJeremy B. Monroe wrote a brilliant article that poignantly discusses why images of freshwater fish underwater are so important in generating public awarenss and conservation of many species and their habitats.  It was the best summation I've ever read, and I'd like to share some of his comments here, (albeit in a heavily edited way) because I wish I had written this article myself.

    "As threats to freshwater ecosystems continue to grow, the vast majority of their inhabitants remain “out of sight, and largely out of mind”. This lack of public awareness of freshwater life may ultimately limit freshwater conservation as a popular cause, or movement. By its nature, aquatic life is inherently less visible to human eyes, and so images, such as photographs, play a critical role in visually connecting freshwater ecosystems to their would-be stewards. And while images by no means replicate human experiences in the natural world, they are a remarkably effective surrogate to enlighten audiences about natural ecosystems and their values. A passing glance at a magazine rack, television programming, and popular internet websites reveals a narrow view of freshwater life. In these popular sources of public information and entertainment, the vast majority of freshwater species are simply unseen, and therefore unknown to most people.  A closer examination of the common images of freshwater life reveals an issue that is perhaps more problematic than mere obscurity. Almost invariably, popular images portray sportfishes and most other freshwater species after they have been “landed” or otherwise extracted from their aquatic habitat. In these images, aquatic organisms are far removed from their natural environment and behavior, which precludes an aquatic, and perhaps empathetic, perspective of their lives and their world. Moreover, these struggling or dead organisms are commonly seen “at the hands” of both anglers, and biologists, portraying a conquering image. Though rarely seen in popular media, underwater images of fish and other freshwater life in their aquatic habitat can more naturally convey the intrinsic and ecological value of these organisms, as well as their evolutionary, and even spiritual aesthetics. These images celebrate the aquatic world by depicting the natural beauty and behavior of freshwater life, the splendor and uniqueness of freshwater environments, and the intricate relationships among species and their habitats. In their natural medium, free of human hands or devices, organisms appear independent of humankind, and their intrinsic value is therefore made more obvious. Indeed, the vision of an organism behaving naturally and relating to its natural environment is precisely what can allow us to sympathize or even empathize with other species and appreciate their significance in our own world or worldview. It is these ecological, evolutionary, and spiritual aesthetics that will presumably resonate more deeply with the broader public, and are most likely to drive conservation movements." 

Nice work Jeremy.  Thank you for putting into words what keeps me doing this.

Video: How Crayfish Escape from Hungry Bass



Smallmouth Bass love eating crayfish, but not every crayfish becomes prey.  Sometimes they’re able to fend off vicious attacks by remaining perfectly still, by adopting a defensive posture, and by simply never giving up.  While bass eat plenty of crayfish, in this video, you’ll see the ones that get away-dramatic underwater footage of crayfish escaping certain death from the jaws of hungry bass.  Make sure you check out our other popular videos on this channel of bass eating crayfish.
(Make sure to adjust your YouTube setting to HD 1080 for best viewing results.)
Special thanks to my longtime friend and professional Foley wizard Tommy Kleinschmidt, of Berlin, Germany for the custom soundtrack for this clip.

Striped Bass Underwater

School of Striped Bass (c)Sean Landsman/Engbretson Underwater Photo
Our Sean Landsman has recently captured some amazing new images of Striped Bass in a North Atlantic coastal river.  Swimming with giant schools of stripers, (some of them approaching 30 pounds) Sean has brilliantly photographed these dazzling fish as they move downstream from their over-wintering homes on their way to spawning grounds and later to summer habitats.  See all of Sean's Striped Bass photos in our Striped Bass Gallery, and view all of Sean's exciting underwater images in our Sean Landsman Gallery.
