Marine biology

Releasing eggs and sperm into the water

In marine biology, to spawn is to release gametes (eggs and sperm) directly into the water column for external fertilisation, a strategy common among fish, corals, and bottom-dwelling invertebrates that often time their release so that many individuals spawn at once. Thorson's 1950 Reproductive and larval ecology of marine bottom invertebrates set out how such broadcast spawning feeds into planktonic larval life and dispersal. The referent is a reproductive event measured by gamete output, timing, and fertilisation success, and it has nothing to do with starting a program, sharing only the meaning of generating many offspring at once.[1]
