Amongst the crossbreeds shipped to market is the machidai, a product of a female red sea bream and male crimson sea bream. Wild red sea bream are bright red in color, but the farm-hatched breed is blackened by UV rays, which takes away from its appearance. On the other hand, the crimson sea bream grows slowly, yet it does not lose its crimson color when farm-raised. Therefore, the two are cross bred in order to create a new species that is bright red like wild red sea bream and grows faster than wild crimson sea bream. Unfortunately, the scales are easily damaged, which led to a new improved species known as machimodoshi, created by cross breading red sea bream with machidai.
