dc.description.abstractWe investigated the population dynamics of a small and little-studied harpacticoid copepod, <i>Microsetella norvegica</i>, in a sub-Arctic Norwegian fjord (Balsfjord 69°N). We sampled with a 90 μm mesh WP-2 net and a 20 L Go-Flo bottle and found that the WP-2 under-sampled all juvenile stages. The abundance and biomass were high, peaking in June with 9349 × 10-<sup>3</sup> ind. m<sup>−2</sup> and 1678 mg C m<sup>−2</sup>. <i>Microsetella</i>were most abundant in the surface, but females and males demonstrated a distinct migration to below 50 m from October to March. Consistently, individual female body carbon content was highest in October (0.39 μg C ind<sup>−1</sup>) and lowest in March (0.18 μg C ind<sup>−1</sup>). Males were present throughout the year, and females with eggs were found from April to September. The average clutch size was 11 ± 2 eggs female<sup>−1</sup>, and our study supports the observation that females can release their egg sac before the eggs have hatched, possibly to produce a new one. With its high abundance and biomass, a flexible reproductive strategy and specialized feeding preferences, <i>M. norvegica</i> is likely a key species in high-latitude coastal ecosystems.en_US
