That is a perfect example of lordosis. A curvature of the spine that is common in hatchery reared fish mostly due to a deficiency

Thanks for that. I'll look that term up.


Can I ask you if this could be as a result of a small gene pool? Came across a number of these when stocking. Fish were from a grow-out facility but the fingerlings came from the main hatchery in the area.


Not enough breeders to spread the genes or something similar?


Thanks also, Al.
