Difference Between Halibut and Turbot
As all I known, Halibut is wonderful game fish for fishermen and Turbot farm in China is economic and pouplar. From the figure, Halibut is large and long and Turbot is more round and short. I'd think that's why Turbot farm is much more pouplar in China. Chinese eat fish in one and meantime round means completeness in China that's also the reason of Mid-Autumn Day. Wow, first taste of this mushy fish today's meal. Won't wait!
Besides the above, let me quote some discuss from fishing forum: 'Pacific Halibut, Has an Anal Spine, large mouth, smallish teeth. White on Blind side. Greenish w/spots on eyed side. (*anal spine is just behind anal vent and bend down the body cavity from the backbone). Greenland Turobt, has NO anal spine and teeth that erupt from the roof of the mouth (vampire fangs) Also has an "L" shaped preopercule. I would say large, white, conical teeth as well. Also has an underbite. Arrowtooth and Kamchatka flounder. NO anal spine, No fangs at roof of mouth. Rounded preoperucle. Tends to be brownish, with brownish/whitish blind side. Kams are out west by russia and look more like a turbot. (darker, as turbot tend to be black.) One thing nobody has mentioned: halibut are smooth as can be when running you hand on the dark side. The arrowtooth and the others, feel more like rockfish.'
