Torches and pitchforks would undoubtedly come for you for those who ate a 6-pound bass and had the audacity to publish about it on social media. The mob’s anger wouldn’t be utterly unjustified as massive bass are glorious breeders which can be vital for producing the subsequent era.
However what a couple of big crappie? Should you’re a conservation-minded angler who loves a fried crappie sandwich, what’s the best-sized crappie to maintain?
I requested that query to 2 biologists from reverse ends of the nation. Their solutions had been as totally different because the our bodies of water they handle. Additionally they include a wholesome dose of “it relies upon.”
Texas Biologist on Crappie Fisheries Administration
Lake Fork is likely one of the finest fisheries within the nation. Ten anglers obtained century belts at a latest Bassmaster Elite Sequence occasion there, and the successful weight was 130 kilos 15 ounces. The lake additionally produces big crappie. I talked to Jake Norman, who’s the Texas Parks and Wildlife district supervisor for the area that features Lake Fork. He says the crappie in Lake Fork are short-lived, however fast-growing.
“Now we have a few of our lakes the place fish can attain 10 inches in a single 12 months, which is authorized size and sexual maturity. So by two years, just about all of our crappie are 10-plus inches and reproducing,” he says. “Their max lifespan is 5 to seven years and the common is three to 5.”
Norman says that whereas massive crappie produce a ton of eggs, they aren’t crucial breeders within the lake. The youthful fish — 1 to 2 years previous — are literally higher breeders.
“They could or might not produce fairly the capability that the biggest fish do. However they’re very viable eggs they usually’re greater than able to sustaining a inhabitants,” he says.
Should you’re in Texas or the same southern state the place crappie develop rapidly, a 2-pound fish is completely positive to maintain.
“If you’re catching two-plus-pound crappie, they’re on the finish of their life anyway. In order that’s a part of the rationale why they’re not as invaluable or as vital to maintain the inhabitants as folks suppose,” Norman says.
There’s an enormous however within the equation, which is the precise lake’s administration objectives. Should you’re fishing an overpopulated lake, the biologists possible need you to take away smaller fish to assist scale back the inhabitants. Norman can provide particular recommendation for folks fishing Lake Fork, although.
“I might in truth say, for sure, harvest no matter measurement fish which can be authorized and that you simply prefer to eat,” he says. “Harvesting bigger fish wouldn’t affect the inhabitants anymore than harvesting 10- to 12-inch fish.”

Wisconsin Biologist on Crappie Fisheries Administration
Nathaniel Lederman is the fish biologist for Oneida County, which has 1,270 lakes, and is likely one of the finest fishing locations in Wisconsin. I requested him the identical line of questions as Norman, and his solutions present the drastic distinction between southern and northern crappie.
Managing crappie in Lederman’s area is just not simple.
“If you put a size restrict on a lake, you see variable impacts among the many totally different lakes,” he says. “So you’ll be able to put a size restrict on one lake, it’s a hit, however you place that very same size restrict on a special lake, and it doesn’t work.”
That’s as a result of in contrast to the regularly heat waters of Texas, Wisconsin crappie can have variable spawning success.
“I feel you’ll be able to boil it all the way down to, at the very least inside Wisconsin, the boom-or-bust nature of crappies. You’ll sort of get a 12 months the place there’s a very good recruitment after which the subsequent few years, you’re not going to have good replica or recruitment,” Lederman says.
This cycle has an impact on the scale construction of a lake’s crappie.
“In order that massive increase 12 months progresses by way of and will get older and bigger, that’s carrying the inhabitants,” Lederman says. “And as folks harvest their numbers, we’ll get fewer and fewer. So so long as the inhabitants isn’t stunted, releasing a few of these people throughout all the measurement construction of black crappies would unfold out that pulse of people, hopefully making it final for an extended time frame.”
Whereas the Texas crappie die off after about 5 years, Wisconsin crappie can reside for much longer.
“Inside Wisconsin, we’ve aged black crappies wherever from age zero to fifteen,” Lederman says. “Age 5 crappies are sometimes round 9 inches [up here]. Granted, that’s very system particular as a result of you may get some methods the place you may get a nine-inch fish in two years, after which different methods it will probably take for much longer.”
Should you’re a northern angler who’s trying to preserve the crappie inhabitants in a given lake, Lederman says that the scale you retain is much less vital than the quantity.
“If the restrict is 25, do you want 25? Or may you be good with taking 10?” he says. “Limiting the quantity that you simply’re truly taking dwelling might need an even bigger affect than deciding on the precise measurement fish. Or, if you wish to take your full bag restrict, simply don’t take solely 12-inch crappies. Attempt to unfold it out the place possibly you are taking a few eight-inch and a few seven-inchers. So unfold what you’re taking dwelling throughout a wider vary of sizes, and likewise scale back that complete quantity that you simply take dwelling.”

The Upshot
Earlier than you choose up that pitchfork in opposition to somebody with a stringer of 14-inch crappie, needless to say it could possibly be a superbly acceptable apply for his or her physique of water. The identical goes for somebody who’s retaining a bunch of 7-inch fish. Consider it like killing a mature whitetail that’s on his final winter and taking pictures does to scale back an overpopulated space.
My predominant takeaway from speaking to those biologists is that freshwater fisheries administration must be carried out on a lake-by-lake foundation. So for those who’re actually serious about discovering out what’s the most effective apply for the our bodies of water you fish, name the biologist that manages them.
