    Default Fish with scoliosis?


    Never knew a fish could get scoliosis, but I googled it and apparently they can. One of the fish we caught Wednesday afternoon looked funny and today when I filleted him I found out why. He had a big hump past his head kind of like a big crappie has, but he was only about .5-.75 lb. Sorry the drawing is a little rusty, but I just wanted to try and depict it for yall. He would lay flat the curve was only up and down not side to side. The only real picture I got of him was on my cell phone and I can't get pictures off of it so I guess my sketch will have to do. Just wondering if anybody had ever caught a fish like that.

    Default cell phone

    My last phone did not have a way to get pictures off of it, but you can e-mail them to your home PC. Just send the pic like you were going to send it to another phone but put your e-mail adress in place of a phone number.

    can't say as I've caught a Crappie with "curvature of the spine" ... but, used to catch alot of Smallmouth, out of Watts Bar Lake (East Tn) with "crooks" in them :p But, for the most part, the crook in their spines was side to side, rather than up & down. (and mostly in the tail section of the fish, but did see some with deformity at mid spine region)

    Most plausible explanations -
    hatchery raised fish (possible) ... because hatchery raised fish can sustain injuries when young/small & penned in heavy numbers. They can also pass on genetic anomalies. And water temp fluctuations, during the hatching/fry period of their life, can cause bent spines.
    wild born fish (most likely) ... water temp fluctuations during egg-hatchling-fry period. Injury as fry to young/yearlings, and genetic anomalies are also a possibility in wild born fish.

    There's also a case of "Fish TB" that causes Tropical/Aquarium fishes to have curved spines ... but, I don't know if this disease is present in the wild.
