Not All Stocked Trout are the Same

A lot has been written regarding native vs. wild vs. stocked trout. For some reason, people (and even state entities) struggle understanding the differences. Being informed and using the proper words is important. More significant than semantics is appreciating and supporting the science behind the terms.

The native/wild distinction is an invaluable one to make when it comes to conservation. The terms mark the difference between historically present species and those which have been introduced and established. For example, brook trout in an untouched Maine pond are native; brown trout descending from fish that were stocked in Maine 50 years ago are wild.

There are other distinctions to make when speaking of trout populations. Some aren’t as noteworthy when talking about conservation. But they do factor when it comes to the fishing experience.

Not all stocked trout are the same.

“Stocked trout” is treated like a pejorative phrase in many fly fishing circles. Images of hundreds of pounds of fish spilling from a game department truck are borderline pornographic. They are perceived as a distantly second-class fish, and the anglers who target them don’t fare much better.

Certainly, there are scenarios where stocking fish is bad for the ecosystem. They can interbreed with native fish, compete for food, or simply take up physical space. But there are also many situations where strategically supplementing streams with trout is perfectly fine. The practice will always have its detractors, but virtually all level-headed fly fishers and environmentalists can appreciate that some waters are okay with stocked fish.

Especially when the stocked fish are good fish.

The stereotypical twelve-inch, pale, zombie rainbow is about as bad as stocked fish get. Hungry for pellets, these concrete-scarred, finless fish are really only good to be plucked out for the pan (even through they aren’t really good for the pan).

Stocked fingerlings, however, are a whole other story. Genetically they are brothers and sisters to the aforementioned rainbows. They come from the same breeders at the same labs. Yet they enter the water as juveniles. Within a season they acclimate to a natural environment. They rise to drifting insects. They develop river smarts. Their colors, both on their scales and in their flesh, brighten up significantly. For all intents and purposes, they look and act wild. And, fiscally speaking, they cost less than a fat, footlong fish.

Another quality option for the angler is the fish that comes from a private hatchery. Nothing against state and federal fishery operations, but they are all about volume production. Family owned or club-run trout farms function like the microbreweries of the aquaculture world. Processes and facilities can create small-batch, craft trout. Some are essentially controlled ecosystems where the fish get a little taste of the real world, while they are also given some protection and nutrition supplements. The end product is a lively, aesthetically pleasing trout. There are, of course, exceptions to this rule. A private company can do bad work while a government-funded entity can be incredibly effective and efficient.

Not all stocked trout are the same, especially when the stocked fish are good fish. These trout aren’t just for put-n’-take. Rather, they populate rivers that have voids in their ecosystem and provide angling opportunities for countless people who would otherwise be troutless. Most stockers do bear the stigma raceways and dogfood. But there are plenty of fish and fisheries that, for now, are better because of quality, thoughtful stocking programs.

  1. Matthew, this is a well argued post. I often write on the wild vs. native vs. stocked issue in my own blog on fly fishing- https://www.sagecreekpress.com/blog. My book “Wyoming Mountains & Home-waters”, was written to specifically address this issue, should you or any of your readers be interested in diving deep into this topic.
    Your blog is fantastic–keep up the great work!
