Pond Boss Forums INTRO Questions & Observations ID on this fish?

Sparkplug,
Yes, I noticed several that were underweight this summer. I have the same GSF problem that I had last year. I had removed 300, but that is no where near what needs to come out. I guess I'll have to get back to fishing and remove some more.

Don't think that is a crappie.

Black Crappie, Pomoxis nigromaculatus


Physical Description:
· Very compressed body
· Upturned nose and mouth
· Rounded pectoral fin
· Slightly notched tail fin
· Anal and dorsal fins nearly the same length
· Large eye
· Speckled body
· Dorsal, anal, and tail fins black with white spots
· Length of dorsal fin base equal to distance from first dorsal spine to eye
· Head and side of body silver with dark marks

Georgia Giant Runt

Isn't that an oxymoron??? You need to come and clear up my water....

Stickem the small GSF go into minnow traps with bait really well and the advantage of catching them small is they are out of the pond before they eat a lot of groceries (taking them away from other desirable fish) to grow.

Set three or four minnow traps and you can get hundreds out pretty quick.

You can trap the next size bigger if you enlarge the opening of the trap (normally 1") to about 1 1/2 to 2" but the fish will eat the food and come right back out. So when I use my modified traps I bait them and check them in about 15 minutes. Check them before all the bait is eaten up. I move lots of CNBG from my sediment pond to my main pond that way too. If you have about 4 or 5 traps you can just about stay busy as by the time you dump and bait the last trap the first one is ready to check again.

GSF go in traps really well. They tend to hang out in shallow water and are real chow hounds, so they go in after the food well.

Get out a hair dryer and get me some solid ground there!

Give me a week without rain...then, it's on!!!

Thought I would put this lepomis traits here and in the sunfish archive. From Wisc Fish an outstanding site with great work. It has pics of the traits and pics of some crosses.

For me it's the mouth; the way the upper and lower jaw extend about the same amount and appears paper thin.....

Wow ewest that's a lot of information and a neat website. Thank you for that. Here's my question stickem also noted he had yoy of the same fish. Would two hybrids of the same cross continue to breed similar looking hybrids? I was under the understanding that hybrids can and do breed but they will favor the traits of one of the two original species and revert back to that species.

Just a few notes on this.

Crosses can never genetically revert to the parent - they are what they are.

Local adaptation and plasticity can and often do effect what a fish looks like and what traits are outstanding.

Hybrid sex ratios in Lepomis are highly variable - see Childers work. No one knows yet how all of the genetic combinations line up in the parents much less in the various crosses. I was told by one genetists that in each human it is estimated that there was/is in that person about 4 billion possible genetic possibilities . People and lepomis have the same number of chromosome pairs - 23. Granted some of the genetic principals work differently in fish and humans but there are still a lot of possible outcomes in one fish , many times that in one species and I woul think many more in crosses. No doubt there are some dominant traits that will reappear but that is just a tiny fraction of the genetic story .

snrub,
...that's a good idea. Never thought much about catching the YOY. I've been concentrating on the 3-5" fish. Will pick up a couple more traps tomorrow before we head up.

If you open the hole up to 2" you can catch 4" GSF but you have to haul them in before they finish the food. Otherwise with the larger hole they can find their way out too easily. I find 15 minutes works well. Enough time for several of them to find their way to the bait but not so long they finish eating.

I have not tried it yet in the traps, but my feed dealer got in some Aquamax LMB feed and I took a couple bags. (Was supposed to be AM MVP for me but the they got the order wrong). I have been using large chunk dog food for bait and it works well. But this AM LMB should be the cats meow for minnow trap bait. 45% protein with fish attractant. I think it is going to be my new minnow trap bait. The pieces are large and should take a while for the small fish to tear apart. The problem with regular fish good is some or all of the pellets fall through the mesh making a bag or some other inconvenient bait holder needed. Large chunks like the dog food or the Aquamax Large Mouth Bass feed just drop in the trap and throw in the water.

If you want to have some fun with your feed trained BG, just throw in a few AM LMB chunks and watch them go nuts trying to devour it. I've seen them knock it plumb up in the air hitting it so hard. Till a 3# CC comes along and it is gone! Hope some day I will actually see a LMB hit one.
