Red Seabream or Sea Bream The name literally translates to the ‘genuine tai.’ It is a fish related to Tai. This savoury fish is also eaten grilled especially since it might contain parasites. Main season for the genuine tai is spring. It can come in red ‘Akamadai’ or black ‘Kurodai’/’Chinu.’ Chidai is crimson sea bream. Ishidai, or Barred Knifejaw or Striped Beakfish, is the striped relative – whose stripes lessen with age – and available in the summer and autumn. Ishidai is considered the tastiest of the family.
