Tosai: literally mean yearlings - fish born from 1st January to 31st December of the year.
Nisai: literally mean second-year fish - Fishes are classified as Nisai when they have transverse the second calendar year of their lives. So even if a fish is borned on the 31st of December, it becomes Nisai the next day on the 1st of January. This sounds strange but if we understand the the All Japan Ranchu Show (AJRS) is held on every 3rd of November in Japan, fishes born in the later part of the previous year would have gained considerable size to compete in the Nisai class.
Oya: literally mean Parent fish - Fishes that have transverse the third calendar year of their lives.
