Whether you use your lake or pond for boating, bird watching or fishing, everyone can agree that they desire a healthy waterbody, especially one with healthy fish. But what constitutes a healthy fishery?  What signs would indicate that a fishery is unhealthy and what approaches could improve an impaired fishery? The health of a fishery can be interpreted in several ways, and the recommended management approaches may vary depending on your ultimate goals.

Goal: A Balanced Fishery

Fisheries managers often describe a healthy fishery as one in which the predator-prey ratios are balanced. This assumes that a sufficient amount of prey (Bluegill, Shad, Shiners, etc.) exist to support predators (often Largemouth Bass) so that they maintain adequate size, growth and condition. Indicators that suggest a fishery is unbalanced could include high catch rates of small fish, a reduction in the maximum size of fish caught or fish that appear significantly underweight.

Lake, pond and fisheries management is often put on the back burner during the winter months as most sport fishing becomes slow, but one species thrives in colder conditions: rainbow trout. Rainbow trout offer a fun fight on a fly or rod and reel for anglers of any skill level—and they make excellent table-fare. No matter your waterbody, rainbow trout can be stocked for fishing and as an excellent source of forage for trophy fish in search of easy meals come springtime.

For avid pondmeisters, there’s not much worse than the sinking feeling of disbelief followed by the rush of anxiety when you stroll to your favorite fishing hole, only to be greeted by hundreds or thousands of white bellies floating around your pond. It’s sickening. Developing and managing a productive fishery requires ongoing effort and attention to detail. It takes fisheries biologists years of practice before we learn enough to maintain high odds of success, and even then, Mother Nature has a way of making things difficult. Even with extensive experience on a biologist’s side, the risk of failure looms.

A significant failure biologists face is when a waterbody falls victim to a fish kill. When a fish kill occurs, it is typically a result of a lethal drop in dissolved oxygen levels. For most warm water fisheries, this oxygen crash tends to occur in the summer months when water temperatures are above 80 degrees. Warm water temperatures, teamed with multiple cloudy days in a row or a rapid drop in surface water temperature from a heavy thunderstorm, are the primary events that trigger fish kills.

Fisheries managers often use pond fertilization to improve the biological productivity of a waterbody, resulting in improved fish growth and abundance. As with any management strategy, geographic location, pond owner goals, and primary use of the water body must be considered prior to implementation. If you are interested in the fertilization process (also referred to as productivity manipulation), it’s necessary to first understand how it works in an aquatic environment. Second, it’s important to understand where it is applicable—or not. Last, you should have a thorough idea of what to expect should you choose to employ this technique in your pond.

Heavy rain has a way of devastating communities and properties across this great country. It seems common to hear of places that receive 6-8 inches of rain within a 48-hour period. During these flooding rain events, lakes, ponds and fisheries must receive a large increase of incoming water within a short period of time, and release excess water in an orderly fashion. When this occurs, fish movement in and out of ponds can be a real concern.

Flooding from upstream occurs when

Pond ownership is a journey that can prove to be exciting and fun, as well as frustrating and disappointing. The good times are typically fueled by great memories of relaxing on the water or catching fish with family and friends, and the bad times are fueled by something that prevents those good times from happening. As owners, we would like the pond to always provide a high level of entertainment, allowing for a continuous stream of lasting memories as well as a source of excitement and energy that motivates family to draw closer together and enjoy the presence of one another.

Over the years, many private waterbodies that became a pillar of lasting memories start to change. Oftentimes these changes occur slowly, and at times it happens so gradually that the transformation goes unnoticed until the pond or fishery have been altered considerably. When this occurs, it is typical for people to be concerned and take action.

Unfortunately for pond owners, the issues that are often viewed as problems are actually symptoms of the real problem.

What led you to pursue a career in fisheries?

"My passion for fish started at a young age. I’ve been fishing since I was three years old. It’s always been a big part of my life, so it was a very natural progression to consider a career in fisheries.

I earned a Bachelor of Science degree in Fisheries & Aquaculture from SUNY Cobleskill and went on to earn a Master’s in Lake Management from SUNY Oneonta.

As part of my thesis, I designed

I could hear his excitement when Mike called requesting a consultation on plans to build ponds and lakes on the ranch he intended to purchase. Upon arrival at the ranch to evaluate the potential for several 1- to 20-acre impoundments, and after consulting a topographic map, I quickly realized Mike’s excitement was about to be severely diminished. The entire area he wanted to develop into scenic lakes and trophy bass fisheries was fed by over 1,600 acres of watershed. This watershed may be suitable for a 150-acre lake in this area but for the relatively small impoundments Mike envisioned, this watershed would have resulted in unmanageable fisheries with expensive and difficult dams to build and maintain. In short, his lakes would have flushed like a Texas tube chute every time a sizable rainfall event occurred.

As you may know, phosphorus is a nutrient that helps fuel the growth of aquatic plants and algae. The amount of phosphorus that waterbody owners and managers want or tolerate will vary significantly depending on goals. For example, a community manager seeking clear water with minimal aquatic growth in their stormwater pond will have a much lower tolerance for phosphorus than a private landowner whose goal is to produce trophy bass or attract waterfowl. Depending on these goals, along with your budget and the characteristics of your waterbody, the maximum amount of phosphorus that is considered desirable or acceptable will vary.

Pursuing your dreams is an incredibly gratifying experience that has a way of bringing out the best in yourself. For some of us, that involves creating a trophy fishery where kids and adults alike can spend time together bonding in the essence of nature. Spending a day on the water with loved ones, in pursuit of the next fish that family and friends will be talking about over dinner or around a campfire, can provide just enough motivation to keep someone from settling when it comes to building the pond of their dreams.
