It's an apt name for the daughter of the superstar mare, with oscietra a popular and expensive variety of caviar.Undoubtedly the filly would have been an expensive purchase had she gone through the sale ring, but she will race under the same ownership as Black Caviar.Oscietra was foaled in September 2014, the first progeny of Black Caviar who retired undefeated with 25 wins in April 2013.Her second foal, a colt by Sebring, was born in September last year.A decision on who will be given the responsibility of training Oscietra has yet to be announced, with Black Caviar's trainer Peter Moody walking away from the profession after receiving a six-month suspension in March over cobalt charges.
