Abstract Spawning of snapper was observed in the public aquarium at Napier. Spawning males were characterised by a grey coloration and spawning females were the typical silvery-pink colour. On four occasions spawning behaviour activity involved several males and one female and on one occasion it initially involved one male and one female, although other males joined in the spawning act. At each spawning event the female swam vertically towards the surface closely pursued by males. Eggs and sperms were released near the surface.
