Eggs of the bluefish (Pomatomus saltatrix) were fertilized and cultured to provide type specimens for identification of pelagic egg and larval stages in field collections. Bluefish eggs, held in seawater of 20 C and 32.5‰ salinity, hatched in 46 to 48 hours. The yolk was nearly consumed 2 days after hatching. Larvae grew slowly and all died by the 8th day after hatching. Identifying characteristics are described for various stages of development of eggs and early larvae and illustrations of typical stages are provided.
