Abstract Starry flounders from San Francisco Bay were brought to spawning condition at the New England Aquarium by means of injections of freeze‐dried carp pituitary. Selected artificial fertilizations were made and the embryos reared through metamorphosis. The first larvae hatched about 85 hours after fertilization. The earliest metamorphoses were initiated 27 days after fertilization at 7 mm standard length (SL); the earliest completed metamorphosis was 33 days after fertilization (30 days after hatching), also at 7 mm SL.
