Crappie Length to Weight Conversion

Recommended Posts

Guest

I was lucky enough this past weekend to catch and release a 15 1/2" crappie and am wondering what the approximate weight of this fish would be? Looking back I may want a replica of this fish on the wall, I did take pictures so it shouldn't be that difficult to get a good replica, but I am curious to what the approximate weight of this fish would be.

Thanks in advance!

I think a 16 inch crappie is usually around 2 two pounds. There are tables that say they weigh more than that, but that's what I've found. A nice fish.

to calculate the weight use this formula

((Girth x Girth) x Length) / 800 = weight in pounds
(girth and length are inches)
Example:
If the fish’s girth is 15 inches and its length is 29 inches, the formula would be used as follows:

15 x 15 x 29, divided by 800 = 8.16 pounds
Then the ".16" or "16/100" is converted to ounces (multiply by 16)
.16 x 16 = 2.56 or 3 ounces
so this fish is 8 pounds 3 ounces

You should post a pic of that slab it would sure be nice to see it.
It's always nice to see a good catch.

FrozenMinnow: I don't think that formula works for panfish... I would say a conservative girth estimate on this fish would be 12", so (12*12*15.5)/800 = 2.79 pounds.

More likely the girth of a big crappie is about the same as it's length, so if this was the case this formula would come out to 4.65 pounds!

So as you can see that formula works good for walleye, pike and muskies, but for panfish, it will be way off.

Hey Sunny, nice fish! I am going to say your fish was about 2 1/2 pounds. Just a rough guess but based on experience this would be pretty close. A legitimate 14 1/4 incher is pretty close to 2 pounds this time of year. I would imagine, depending on how you measured the fish that it would be atleast 2 1/2 pounds. Nice fish!

Hey Scott.

Thanks for the information! That is what I was estimating as well just by feel, but I wanted to confirm with people who would know.

I really wanted to drop you an email about the RCL co-angler you were looking for a couple weeks ago. We could have an all Speckville boat! Yes I am from Richmond too, you will remember me from the golf course. But with our first baby on the way I don't know how much time I will be able to dedicate chasing walleyes this year. Let me see 85 days on the water last year, divide that by about 5 and that should give me my projected total for this year. New boat will not get a very hard work-out this year I guess.

Maybe sometime in the near future I will have the priviledge to do some serious walleye fishing with you.

Take care and thanks again for the info...

SUNNYD - aka John Sundet

p.s. If I send you the picture Scott can you post it for me?

Frozenminnow:

I've used that conversion formula for the last 8 years, and I think it works far better for long-bodied fish (well, relatively long-bodied fish) like pike, 'eyes, trout and catfish.

Pannies are so short and tall and narrow that I've found it doesn't work as well for those.

I'm going to disagree with most everyone else about the potential weight of that 15.5 inch crappie. I've caught crappies to 14.5 inches, and the biggest of them weighed 1.4 pounds. I don't buy that an extra inch of length will get you another pound to bring it to 2.5 pounds. I think your 15.5 inch fish might have weighed 2 pounds. Maybe. And the longer a fish is, the more weight is packed on by adding another bit of length.

In the end, who cares? A crappie that long is a fish, if not of a lifetime, at least of a season, so congratulations. grin.gifgrin.gif

We weighed two fish a couple of weeks ago, one crappie was 15.75" and weighed 2 lb on the nose, the other was exactly 16" and weighed 2.2 lbs. A centimeter in a pannie makes a world of difference. Two incredible fish that I will never forget, caught less than 30 minutes apart.

according to the formula it shows it is 2 lb 13 oz. that is possible I would re measure the girth to be sure though,
(12*12*15.5)/800 = 2.79 pounds.
.79 * 16 = 12.64 rounded to 13 oz.

we got a 14" at Red last year it weighed 2 lb 3 oz and several in the 11-13 range and they all went 1.75- 2 lb
The Minniesota state record is 21" 5 lb.

I would put it around 2.13 pounds. A couple sites I checked have it anywhere from 2 pounds to 2.33 pounds. Nice Slab!

I would say that fish, 15 1/2", is pushing 2 pounds. I've caught 15" plus crappies from Rainy Lake, Lake of the Woods, Red Lake, and other smaller lakes in northern Minnesota and not a one was a legitimate 2 pounder. I think a person has to shoot for 16" to reach that mark on most bodies of water. Usually goes like this (general idea)~ 12" = 1 lb, 13" = 1 1/4 lb, 14" = 1 1/2 lb, 15" = 1 3/4 lb or a little more.

My observation anyway. Still a nice fish in my book. Congratulations!

For starters it usally depends where you are fishing. I don't know where Steve Foss is fishing but I have never had a crappie 14 1/2" weigh in less then 1lb.12oz. When crappies start to hit 13" on up it matters on thick they are and how wide they are. I have had 2- 14" crappies laying side by side with one of them being a 1/2" wider and it had 1/2" thicker shoulders, at least 2-3oz larger. My largest has been a 16 1/2" weighed 2lb 13 oz. (I mounted that before catch and release became popular). Congratulations SunnyD that is a trophy and depending on the width and the shoulders, it could very well hit 2 1/2 lbs.

Have Fun!

Greg you are right on the money. Looked at my fishing log and I recorded 14" crappie
1 LB. 8 OZ. 15" crappie 1 LB. 13 OZ. These fish were caught west of Remer. A 2 pounder is a hog.

Does anyone remember about 18 years ago the 4 pounders caught at Battle Point on Leech?

Ok guys, you almost have me laughing here. You can't just throw out a formula for fish because nothing takes into account the time of year. You will notice that I said in my first post, this fish would way roughly 2 1/2 this time of year.

Much different in summer and in Spring. A 15 1/2 inch fish caught this time of year can and should way over 2 pounds. As we get closer to spring this fish will put on ever more weight. Post spawn, reguardless of the success of the spawn this fish will lose weight.

I have caught 14 1/4 inch crappies in the winter (Jan) that have weighed 2 pounds exactly. The same length fish prior to spawn weighed 2.36 pounds. I have yet to catch one that size post spawn but I would guess it would be under 2 pounds based on smaller fish I have caught.

I can also add that I have never seen a 15 1/2 inch slab weigh under 2 pounds anytime of year. Just some observations.

Sunny, I knew exactly who you were before you mentioned your name. Nice slab and I am still going to say it was roughtly 2 1/2 pounds. Great fish!

Roadkill, I think your data is pretty good!

Thanks for the compliment scott! Sounds to me like you have had your share of big crappies. I don't know how old you are, but are the big crappies still able to be caught in Mille Lacs in the winter? 20 years ago it was more of the locals only fishing for them. We managed to get on to them, it was great! They would bite all day slow but steady and you could get your limit of 12"-14" fish.

Have Fun!

    • In late summer end of July and August when the water warms and the oxygen drops in the shallows. I have caught Eye's trolling deep diving raps, plugs behind dispy divers for suspended fish over 50-70 feet of water where the bait balls are. So, yes please don't follow us lost crazy people around out there! 🤪  😁
    • They call it 'No Man's Land' because nobody fishes it, unless they are lost, stupid or their locator is in simulation mode. That works for me because that's my comfort zone. Most people wouldn't believe the numbers of trophy fish I have caught in water that's over 50' deep. Recently I was out on a local lake trolling for walleyes in deep water with shallow and medium diving crankbaits, and I noticed 3 other boats that were avoiding the normal structure. Maybe their locators were broken or in demo mode, but for there to be 4 of us driving slowly around the open water, it seemed like more than a coincidence. I boated 4 eyes in 4 hours, with a smaller average size than I was hoping for. I am not looking for lakes, spots or secrets.... I am just curious if anybody else has noticed these 'fools' fishing water too deep for 'normal' fishing. Or maybe you have tried it a time or two, let me know what made you steer your boat away from the shoreline? Did it work out for you?  Is this style of fishing becoming more popular, or am I just paranoid?
    • Don't know yet if there are more.   
    • nope, they just like my bluebird houses! they got evicted again 2 nites ago!!!!!!!!! i learned a long time ago no millet. i only feed sunflower and safflower seed along with thistle!
    • WinnerDinner, what do you fish for there In Ireland?  
    • Well there's that! 👍  
    • Speaking of lures I remembered something... Recently I have been trying to understand how to fish at night, was never really much of a fan before. Don’t overload yourself with tackle when fishing at night. Use a smaller tackle box and make use of two or three separate, small containers for all the necessary items like hooks, weights, small bait etc. Night-fishing success means not using bright lights and being very quiet. I feel in love with my new glow in the dark fishing lure, it is so underrated, there are quite a lot of these glow in the dark lures at places like Amazon and such. According to veteran fly-fishermen trout that are all but impossible to catch during the day will be more likely to hit at night. Why? Because these fish are nocturnal feeders. They venture out from under the logs and out of the deeper holes to feed in the shallows. Of course, when you’re seeking trout or other shallow feeders at night you’ll have to take extra precautions to stay safe. So far I've been doing good with my night fishing adventures.
    • My "BROWNING STRIKE FORCE SUB MICRO" was a dream. It really stands out for its exceptional daylight clarity and amazing battery life. The images this game camera can capture put most 12MP cameras to shame. It also uses power very efficiently, even with heavy use of video – especially if you install a set of lithium batteries.  You can expect several months’ use out of them which is even more impressive when you consider that it runs on six AAs, instead of the more common eight.
    • They only have 2 options in life: 1 - get hunted. 2 - get ran over.
    • Crazy thing just happened to me while fishing off my dock... Was throwing a topwater, not paying attention, and SPLASH, I set the hook and nothing there. As I was reeling in to try that spot again, I heard something in the big pine next to the dock, but didn't think anything of it. Recasted and heard something again, turned my headlight on in time to see an owl heading to and then kinda hovering over my lure...  I thought that was weird... A couple casts later I hooked a small bass.... Then I lift it out of the water and as I'm reaching for it, the crazy owl swoops down and about hit me as it tried to nab my bass!!! Holy $#!+ I said out loud and decided to go up the hill before I got attacked. But not until I got pics and videos of the brave bird.  Last summer I had a very similar up close encounter with a great blue heron and a crappie, right at dusk with a heavy fog coming in... Not sure which one surprised me more!!
