A Critical Look At Artificial Fish Habitat:

When considering fish habitat, I think we need to discuss the role artificial fish habitat can serve. They're being used more and more, especially in large southern reservoirs devoid of important structure fish need.  Fish managers have traditionally placed bundles of Christmas or cedar trees on the lake bottom to provide cover for fish.  Because the lifespan of tree bundles and brush piles is limited, replenishing them has always been an ongoing and expensive process.  One advantage of artificial habitat structures that help explain their growing popularity is that they don't decay or deteriorate.

But can “anything” man-made be placed in our waters and be called fish habitat? If we throw a rusty wheelbarrow into a lake today and catch a fish on it next week, can we genuinely say we’ve added fish habitat and therefore improved the lake? Are we unknowingly turning our lakes into landfills or the equivalent of the town dump under the guise of creating fish habitat? Is it really true that any structure of any kind is better than nothing?  If you’ve ever wondered if there’s any discernible line between “junk” and authentic fish habitat, you wouldn’t be alone.

If there’s any hope of understanding the potential benefits using artificial fish habitat might offer, I think we need to uncouple two terms: Fish habitat and fishing. Effective fish habitat needs to protect young fish too small to be of interest to anglers. The metric to evaluate how useful fish habitat is must be re-calibrated. The question shouldn’t be how many trophy bass did you catch this year on the habitat, but how many young-of-the year bass survived the brutal gauntlet of their first year of life because of the protection that habitat provided. 

It could be argued that the most successful fish habitat would be one that only attracted age 0 fish and was a lousy fishing spot. As anglers, we need to modify our point of view. Fish habitat should be regarded as an investment in the hope of a better day’s fishing in the future, not something with instant payoffs today. If fish habitat isn’t a vehicle for fish recruitment, what good is it?

Today, there isn’t a single designer of any artificial fish habitat that doesn’t promise their product or design will protect young fish. These are merely assertions that haven’t met their burden of proof. These claims must be demonstrated before we have warrant to accept them as true. Where is the evidence that any assemblage of man-made parts and scrap material does anything to help even a single fish survive its first year, let alone to adulthood? So far, Fishiding is the only design that has continuously and consistently documented in hundreds of underwater pictures and videos over the years the efficacy of their product.

If you work in the fish management sector, you should absolutely demand evidence that whatever artificial habitat you’re considering spending resources on legitimately works. As condescending as it may sound, intuition or gut feeling is not evidence. If we’re not more careful about scrutinizing and properly evaluating artificial fish habitat, we run the risk of unknowingly crossing what should be a distinct line between what authentic habitat is and what’s simply junk.

What we Can Learn From Fish When We Spend Time With Them:

Do fish have individual personalities? I'm often asked this question and I have some definite thoughts about it. For me, the answer is unequivocally yes. I’ve been photographing fish underwater in their natural habitat for over 25 years. In that time, there are long stretches when I’ve worked with the same individual fish for years at a time. I think most would agree that just like the personality distinctions one could make between say poodles and collies, distinctions between different types of fish certainly exist. Northern pike have different personality traits than largemouth bass and bluegills. Each species possess their own “group personality identity”.  But I would also suggest that it goes further than that. Individual fish behave differently from their cohorts and exhibit what can only be regarded as unique personalities with as much depth and richness as those of our own pets. 

Epiphanies about fish like this one can easily escape the casual observer and are only possible when one spends an extended amount of time observing and interacting with them. But because fish live in a world separate from ours, it’s difficult to do this in the same way birdwatchers can for example.  To observe fish in their natural habitat, we have to go under the surface with masks & snorkels or diving equipment. 

On warm summer days, our lakes are filled with swimmers and boaters, but they’re largely unaware of the diversity of life that swims just below them. We’re deaf to a grand symphony in concert under the surface. In recent years kayaking has become a very popular way to enjoy our waters. I’d love to see snorkeling gain that same kind of popularity in our inland lakes and become something you do every weekend, and not just when you’re in Hawaii on vacation. 

I’d encourage anyone interested in animals, and especially those interested in fish specifically to explore snorkeling as a way to observe and enjoy fish. They’re so fascinating to watch and there’s much we can learn about them.

What are the Clearest Inland Lakes in Wisconsin? The 2020 Report:

For the best underwater photography, finding clear water with high transparency is essential. So what are the clearest lakes in Wisconsin?  Every year, I consult with Wisconsin's state-wide citizen's lake monitoring group. They're a network of individuals, usually lake-front property owners who monitor and regularly take a variety of water samples from lakes all across Wisconsin.  The data they compile helps to give us a look at how our lakes are doing. 

One of the many tasks lake monitors perform is to take regular Secchi disc readings. This is a universal way of assessing and comparing water clarity.  I'm always interested in knowing which Wisconsin inland lakes are the clearest.  Ordinarily, I rank the lakes that recorded the highest average water clarity for the previous year. This year, I'm looking at lakes that recorded the single highest Secchi disc reading in 2020. Because of Covid-19, not all the usual lakes were sampled at their usual intervals, so we have only the data that was collected. With that in mind, here are Wisconsin's clearest inland lakes and their highest single-day water clarity readings taken in 2020:

1)   Upper Eau Claire Lake, Bayfield Co. 39.5 feet

2)   White Lake, Marquette Co. 36 feet

3)   Middle Eau Claire Lake, Bayfield Co. 35.75 feet

4)   Whitefish Lake, Douglas Co. 35 feet

5)   Blue Lake, Oneida Co. 32 feet

6)   Lee Lake, Oneida Co. 31.5 feet

7)   Black Oak Lake, Vilas Co. 30.5 feet

8)   Forest Lake, Vilas Co. 30.5 feet

9)   Stone Lake, Washburn Co. 30 feet

10) Pearl Lake, Waushara Co. 30 feet

11) Lower Eau Claire Lake, Bayfield Co. 29.75 feet

12) Bass Lake, Oconto Co. 29 feet

13) Smoky Lake, Vilas Co. 29 feet

14) Sugar Camp Lake, Oneida Co. 28.5 feet

15) Upper Nemahbin Lake, Waukesha Co. 28 feet

Why Underwater Photography in Freshwater?

I'm often asked why I'm interested in freshwater fish like bass and walleye.  Well, the freshwater world has never had an ambassador in the same way the oceans had Jacques Cousteau.  Perhaps, all of us who spend time in lakes can collectively be some sort of equivalent to that.

I think there’s always room for more good photographers, and I think interest in freshwater fish will continue.  I’d encourage beginners to learn about their subjects.  Become an expert on the life and behavior of these fish.  Become a steward of their habitat.  Whether it's a musky, a largemouth bass or a bluegill, think of yourself as a PR person for that particular fish.  If you do this, you’ll show them in the best light, you’ll be mindful of disturbing them, and your work will automatically show these creatures at their most magnificent.  Don’t sell pictures or videos.  Instead, fall in love with your subjects and sell that love!  And instead of exploiting them for personal profit, you’ll become partners with them in calling attention to their inherent beauty and value in the ecosystem, and the special problems each one of them face in an increasingly crowded world.

How to Use GoPros to get Great Underwater Fish Videos

Whether you're scuba diving or just snorkeling, shooting nice underwater footage of fish from a nearby lake has never been easier. Here's a few answers to questions I'm often asked by beginners:

Where can I go?

No matter where you live, there's probably a pond, lake or river nearby teeming with fish and other interesting underwater subjects. It's important to find the clearest body of water you can, since clarity is critical to underwater videography. Contact your state's fish and wildlife office. They're very familiar with the characteristics of local lakes and can point you in the right direction.

Which GoPro should I use?

Gopro seems to come out with a new camera every year.  Their latest, the Hero 9 is their best by far. Waterproof to 33 feet without a supplemental housing, it's video and stabilization capabilities are superb. If you can't afford the newest GoPro, the Hero 8 and Hero 7 are also good choices. I wouldn't suggest using anything older than the Hero 6. The earlier models (1 thru 5) just don't work as well.

Do I need to use a filter?

If you use strobes as I do, you won't need filters to correct for losses in the light spectrum which filters are designed to compensate for. The term "strobe" is a bit of a misnomer. Basically any powerful waterproof flashlight will work as well. If you use strobe lights, you'll also need a handle and tray that you can attach your camera and lights to. This keeps everything together and is easy to hold and swim with.  Strobe lighting is wonderful because it brings out colors and fills in dark shadows. 

How do I get close to the fish?

The best way is to let them come to you. If you remain relatively still and non threatening, fish will usually come right to you which makes your video of them much more interesting that than the "tail shots" you'll always get if you chase them.  Fish are naturally curious and if you're patient, you'll find that they'll swim directly into your lens on their own.

I don't want to get wet. Can't I just mount my GoPro on a pole and shoot video that way?

You can try, but you'll be frustrated. Using a pole cam seems like a good idea, because you won't have to get your head underwater. But because you're not able to see through the viewfinder, you'll never be sure your videos are being framed correctly. I've shot many videos using pole cams trying carefully to aim the camera at the fish. Many times I've been disappointed because I've guessed wrong and the fish was barely in frame. When you're underwater, the aiming is precise every time. Also, being underwater with the fish is half the fun!  

If you have any questions about using GoPros to film fish, please let me know. I'm happy to share what I've learned over the years. Filming fish underwater has never been easier, and most anyone can get great underwater video with a little patience. If you try it, let me know how it goes for you.
