A Japanese mother forced her teenage daughter to eat more than 30 of her pet goldfish as a punishment.

Yuko Ogata and her boyfriend Takeshi Egami, who have both been arrested, made the girl eat the dead fish in June, police told AFP on Wednesday, adding that the daughter was allegedly abused on a daily basis.

No damage to the daughter's health has been reported, according to local media.

According to the health ministry, Japan's child protection centres dealt with a record 89,000 abuse cases in the year ending March 2015.
