Why Do-It-Yourself Artificial Fish Habitat Fails:

Fishiding Artificial Fish Habitat is unique because of its size, complexity, and the protection it provides juvenile fish.

Constructing a conglomeration of rubber tubing, plastic barrels, and old hose, throwing it into the lake and calling it fish habitat because we saw a bass next to it, is like putting a cardboard box on the street corner and calling it “housing” when a homeless person takes refuge in it. Most DIY fish habitat is as much fish habitat as a plastic tarp strung between two shopping carts is “a house” to a homeless person.

Look around at your own home. Why is it comfortable? Why do you like it? Look past the man cave you’ve built in the basement, the expensive wall-to-wall carpeting, and the refrigerator with the built-in ice-cube dispenser. What makes your house useful and practical is its utilitarian functionality.

The insulation keeps you warm in the winter. The roof keeps the rain out. There’s a dark bedroom to sleep in at night. The doors and windows all have locks that provide you with safety and security. Your pantry is stocked with food and you have a kitchen to prepare it. Your home functions in a way that addresses all your family’s needs in a utilitarian way.

By and large, DIY artificial fish habitat doesn’t do anything close to that. To be comparable, artificial fish habitat needs to be large to accommodate many fish. (You wouldn’t want to live in a one-bedroom bungalow with a family of six would you?) It needs to provide a refuge for young fish the same way your children have their bedrooms where they can be away from grown-ups while hanging out with their friends. There needs to be on-site food so you’re not driving to McDonald’s every single time you want a snack. Size, security, protection, privacy, and food are just some of the important aspects of any home that we would never compromise on in our dwellings yet seemingly never consider when constructing habitat for fish. Instead, we create the equivalent of tent cities in the most impoverished part of town and congratulate ourselves when homeless people congregate there to get out of the rain. That’s not a solution to the homeless problem any more than lashing rubber hoses to cinder blocks is to solving the lack of fish habitat.

What’s needed in both scenarios is genuine housing/habitat for both impoverished people and fish.

When looking at the wide variety of homemade so-called fish habitat, one thing seems to be evident. Most well-intentioned builders don’t seem to know exactly what fish need and the poverty of their designs betray this fact. Bad designs continue to be copied, while far superior ones are ignored. This is because so few of us can tell the difference between good designs and poor ones. This failure is epidemic but also understandable. Fish live in a separate world largely invisible to us. We rarely glimpse them in their natural habitat and have little idea of how they live or how they spend their time. Our only interaction is when we hoist them into the boat on the end of our fishing lines. Occasionally we notice that fishing under the neighbor’s dock or next to that old Cyprus tree stump seem to be good spots, but we’re completely in the dark about why. We often leap to the false conclusion that any structure in the water is a fish’s home and any solid piece of material we find in the back of our garage could work just as well. Do it yourselfers are thwarted not only by their lack of understanding of fish but also by what materials might currently be available in their sheds and garages. I think this explains why we see so many awful constructions.

To design and construct authentic fish habitats and not merely dilapidated, makeshift shelters of the kind we might see on urban streets, we need to think backward. We need to think first about function over form. Utility over availability. We need our designs to meet the specific needs of fish. We can look to natural habitats for guidance. Natural habitat has a myriad of desirable characteristics but for this discussion, we can single out the three most often violated elements that any proposed artificially constructed fish habitat must have. The first is size. Is our construction large enough to accommodate a community of fishes? The second is protection. Are there tight spaces, crevices, alleys, pockets, holes, depressions, and retreats that smaller fish can occupy that larger fish absolutely cannot access? The third is complexity. Is the structure large and complex enough to offer shade, to block sight-lines, and to hide or conceal what’s in and around it? If it were in your backyard, could your kids use it when they play hide and seek?  Keeping in mind this trio of primary functions will help you begin to understand what fish need and enable you to reject bad design ideas and eliminate potential construction materials that don’t amplify these important characteristics.

Across our country, there are many bodies of water from large sprawling reservoirs to small backyard ponds. Many of them are lacking fish habitat for a variety of reasons. In many cases, artificial habitat can be a surrogate but only if it addresses in utilitarian ways the features of genuine habitat. 

If you work in the fish management sector, you and your colleagues have an obligation to be very critical of the designs being paraded in front of you. If we’re not more careful about scrutinizing and properly evaluating artificial fish habitats, we run the risk of unknowingly filling our waterways with useless materials instead of creating legitimate habitat. 

Certainly, there’s much to discuss about creating artificial fish habitat, and because true innovation has slowed to a trickle, we find ourselves mired in a kind of estuary between realizing we have a habitat deficiency and creating the kinds of authentic habitat that will make any difference. Artificial fish habitat needs to provide functional value to our fish. The scale of the problem is enormous in many locations, and won’t be solved by adding more sub-standard and inadequate structures any more than human homelessness can be solved by putting out more cardboard boxes and tents. 

Summer Largemouth Bass-Where to Find Them

It's late summer and we're getting some really attractive Largemouth Bass images showing these fish using thick weed cover and a variety of other natural habitat elements.  

At this time of year, we face several obstacles when photographing bass. They tend to be harder to find because they're occupying all areas of the water column and tend to be widely dispersed. Water clarity diminishes this time of year as well, making normally suitable lakes too murky or "green" for good photography.  Finally, there's a seasonal shift in attitude of these fish by August.  Bass that were very approachable in the spring have become more wary and timid by late summer, so getting closeups of them becomes more difficult.  

Despite all those challenges, we're still able to get some fine images of them in their natural habitat.  Check out all our latest Largemouth Bass in our Largemouth Bass Gallery.

Do Fish Have Individual Personalities?

I'm often asked this question and I have some definite thoughts about it.  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.  Because of that, I think I’m uniquely qualified to comment on whether they have individual personalities or not.  The answer to this is unequivocally yes.

Just like the personality distinctions one could make between say poodles and collies, distinctions between different types of fish certainly exist. And not only do entire species like northern pike, largemouth bass or bluegills have their own group personalities, but individual fish in the group have theirs too.  The individual fish and their unique personalities have as much depth and richness as the personalities of our pets. Sometimes I want to assign all the fish of one species with a label.  At first, I’ll think something like, “You know, Black Crappies seem to be a little aloof”.  But then I’ll remember one or two that I’ve met that weren’t and it makes me reluctant to paint the whole species with a broad brush.    

If you're skeptical of the idea that fish have personalities, I would say that you have to get to know them to understand that.  Very few humans have forged anything resembling a relationship with a fish.  Certainly, few people have connections with wild fish.  When you spend the enormous amounts of time I have with fish, secrets like this reveal themselves to you.

So what are some of the different personality characteristics of fish? Here are a few common species and the traits I think they demonstrate, based on decades of underwater interaction with them:
 
Largemouth Bass: Clever; Focused; Innovative   
Smallmouth Bass: Curious; Enthusiastic; Assertive;   
Walleye: Stoic; Contemplative; Organized;   
Musky: Uninhibited; Clumsy; Suspicious;
Northern Pike: Timid; Patient; Obsessive;  
Bluegill: Friendly; Daring; Active;
Carp: Alert; Decisive; Anxious 

What Do Fish Think of Humans Who Scuba Dive Into Their Homes?

I've been photographing fish underwater for twenty five years and this is a question I've thought about a lot. I know what's it's like on the lake bottom taking pictures of fish, but what's it like from the fish's point of view?  How do they process the experience?  I can’t imagine what it’s like for them, but let's try to experience the encounter from their point of view.  Let's imagine for a moment that the roles are reversed.

So imagine you’re sitting in your living room one day and then, out of nowhere, an alien creature enters your home. It doesn’t resemble anything you’ve ever seen before. It has eyes like you do, but there’s very little about its body that you can comprehend. It doesn’t resemble anything you’ve ever seen. It’s enormous in size and you’re not sure where it came from or why it’s in your home. You’re terrified. But…. you might also be a little curious. You’re torn between running for your life, and trying to understand what you’re seeing. Let’s say you choose not to run. You keep your distance and start observing this alien life form. It’s immediately obvious that this creature has severe limitations. It seems to be clumsy and awkward. It doesn’t move with any grace or fluidity. In fact, it seems to have difficulty moving around at all. It’s also slow. This is reassuring to you because you’re certain you can outrun it easily if it approaches too closely.    Then suddenly it moves up to the ceiling of your living room and seemingly disappears. Where did it go? The entire encounter is incomprehensible to you. This is how I imagine the first time encounter would be like if the roles were reversed.

I can’t imagine what fish think of us.  But I’m always impressed with the fish that don’t immediately flee. I don’t know if I would have the nerve to hang around and observe this strange monster in the scenario I described. It’s extremely humbling to realize that these fish are braver and have more courage than I would in their situation.

I think after many repeated encounters, a certain level of comfort develops. While fish may never understand what we are, they know we’re not the otters they see who move with great speed and agility and should be feared. We’re probably regarded more like the way they view snapping turtles. Large, plodding creatures with no real underwater skills who aren’t a threat unless they get very close.

Over time, the fish begin to notice that as we clumsily move through the water, we create a disturbance. Unseen insects and other invertebrates that are hiding on plants or on the lake floor may be exposed or displaced and to the fish, they magically appear for them to eat. Maybe a crayfish is suddenly seen fleeing and again a food item is summoned out of nowhere. They may begin to view us as sorcerers who can conjure up food items by our mere presence. If they arrive at this conclusion, the entire dynamic between fish and us changes. We become viewed as a waiter or sorts. Instead of fearing us, we instead become something that should be paid attention to and even followed around so they’re able to snap up any treats that we may cause to appear.  For this reason, eventually, over time, I would say some of the fish are absolutely gleeful when they see us.

Fishiding Leads the Way in Artificial Fish Habitat-Designed By Fish, For Fish

Artificial fish habitat structures are becoming more popular today.  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 trees or cedar trees on the lake bottom to try to provide cover for fish.  While effective, the lifespan of tree bundles or brush piles is limited, so replenishing them has always been an ongoing and expensive process.  Today, artificial habitat structures are gaining popularity because they don't decay or deteriorate. 

Of all the outfits manufacturing artificial habitat, David Ewald's Wonder Lake, IL company Fishiding, is ahead of all others, at least if you ask the fish, which is what David does.  Ewald has recently introduced his latest models:  The High Rise.  Ranging in height from 8 to 14 feet, these new designs are the only artificial fish habitat on the market today that incorporate the vertical element.  They tower off the lake floor and provide legitimate structure for fish, unlike his competitors who largely manufacture small and short structures that are inconspicuous to fish and do little to provide them with the kind of cover they're looking for.  The vertical dimension used in Ewald's High Rise models gives fish a range or depth at which to stage, and mimics the effectiveness of sunken vertical timber.      

Ewald's company, Fishiding sells a variety of different fish habitat structures that continue to evolve.  The reason for this is repeated testing.  Ewald monitors test structures over time and modifies them based on how fish respond to them.  The prototypes that don't attract as many fish are retooled and modified until they do or even scrapped altogether.  In effect, the fish vote, and new habitat is designed based on the observed preferences of fish.  No other artificial habitat structures are custom made for fish preferences the way Fishiding is.  When Ewald learned about the often overlooked but highly important vertical dimension, he got to work designing new models that would address this important fish preference and give fish what they want.  The result is his High Rise line of structures.  "Fishiding's artificial fish structures are designed not by what we think will be effective, but what they fish tell us they prefer", says Ewald.
