Abstract

Physical data do not support the hypothesis that either a stationary or shedding eddy field exists downstream of the island of Barbados. Analysis of larval reef fish distribution suggests a strong concordance with certain features of the physical flow, notably the offshore flowing convergence and the return flow NE of the island. Larval reef fish densities are extremely high very nearshore (<1.5 km) at mid-island suggesting either a region of low flow, onshore flow, and/or active behavior on the part of the larvae resulting in the retention and/or return of larvae in this vicinity. Analysis shows highest larval concentrations at 10-30 m and 30-60 m depths, with some family level differences. Onshore flow is also evident (especially nearshore) at depths of c50 m corresponding to the depths of high larval concentration. -from Authors
