Summary Juvenile fish are important prey for marine birds and mammals. The objective of this study is to characterize the juvenile fish near the Isles of Shoals. Neuston nets and beach seines were deployed from 2021-2025. The neuston net was deployed 118 times and the beach seine was deployed 7 times. Neuston net fish catches were ichthyoplankton ranging from about 5-35 mm total length (TL) and beach seine fish catches were juvenile fish ranging from about 15-210 mm TL. Neuston net catches were high in 2022 (up to about 20 ichthyoplankton per deployment) and low thereafter (typically 0-2 per deployment). Beach seine catches typically were a few hundred fish and were more consistent from year to year. In the neuston net catch, common fish species were red hake (Urophycis chuss), white hake (Urophycis tenuis) and fourbeard rockling (Enchelyopus cimbrius). In the beach seine catch, common fish species were American sand lance (Ammodytes americanus), Atlantic herring (Clupea harengus) and Atlantic tomcod (Microgadus tomcod). The largest beach seine catch of herring was in 2025 (159).
