摘要

This paper describes a method for estimating larval supply of a temperature reef fish, the kelp bass Paralabrax clathratus, that is simple, inexpensive, requires relatively low effort, and inte- grates larval supply over time. Using this method, we sampled larval supply concurrently at 4 sites spread over about 35 km for nearly an entire settlement season. With these data and visual estimates of recruitment(the density of young-of-the-year after the end of the settlement season), we tested the hypothesis that spatial patterns in recruitment were set by larval supply.
