It's like pruning a peach tree. If you have a peach tree you have a choice. If you prune it properly you'll get lots of nice big peaches. If you don't prune it you'll get 3 to 4 times the peaches they will just be much smaller..
Good analogy. Fisheries managers have the same decisions to make with fisheries. A fishery is basically a bucket. When filling the bucket with marbles, you have to make a decision of what size marbles you want to put in the bucket. You can have a bucket full of a lot of small marbles, a mix of small marbles, medium marbles, and some big marbles, or a few big marbles.
The important thing to remember is that once the bucket is full, you can't just add more to it. Often times we hear anglers wish to simply "add more forage". That would be great, if the bucket wasn't already full. Sometimes you have to remove some fish before you can add more forage. You can't just add more if the bucket is full.
fisheries managers have a delicate balance that they must attempt to control, depending on what anglers desires are: lots of fish vs. quality (big) fish.
The challenge with Lake Powell is that it is a VERY LARGE bucket. So as much as managers might attempt to manipulate different variables, sometimes they really have no control at all.
Managers have 4 tools available to them to manage a fishery:
1 -- rules and regulations
2 -- public relations and education
3 -- fish stocking / fish removal
4 -- habitat improvement
We see nearly each of these in play at Lake Powell. Limits on specific species (1) tie directly with fish removal (3), along with Wayne's website and continued education (2) on how to catch, keep, filet, cook, etc. stripers, walleye, and other species swimming in Powell. Habitat manipulation (4) is a pretty difficult task at Powell. How do you manipulate spawning habitat in a lake that covers 250 square miles and contains over a dozen different species of fish spawning at different times under different circumstances with ever changing water levels? You can't. So you rely on tools 1 - 3 and hope you can make a difference.
That's where education / public relations comes in to play -- and where Wayne shines as a biologist. His progress educating anglers, specifically about stripers, has been phenomenal! His website contains a plethora of information where anglers can learn and better understand the what's, why's, and how's of fish in Lake Powell. Now it's up to us to decide what we do with that information.
