| Abstract: | Larval fishes were sampled weekly from late fall to early spring in the Newport River estuary just inside Beaufort Inlet, North Carolina. Quantitative samples were taken during darkness at mid-flood tide with paired 60-cm bongo nets (505-μm mesh). Larvae of 22 species from 15 families were collected. Seventy-seven percent of the species and 97% of the individuals were fishes that had been spawned on the continental shelf and had immigrated to the estuary. In descending order, the five most abundant species, accounting for 90% of the individuals, were spot (Leiostomus xanthurus), Atlantic croaker (Micropogonias undulatus), Atlantic menhaden (Brevoortia tyrannus), pinfish (Lagodon rhomboides), and speckled worm ell (Myrophis punctatus). Most species immigrated through-out the winter and into spring, but there were distinct patterns in their temporal abundances. |
