Description:A comprehensive understanding of the life-history strategies and habitat use of species is essential for developing accurate ecological models and effective management and conservation strategies. For example, omitting critical habitats of endangered species when estimating their abundance and when designing conservation plans can severely limit our understanding of population dynamics and lead to poor management outcomes. Here we describe important new observations of the distribution and habitat use of Longfin Smelt (Spirinchus thaleichthys) in the San Francisco Estuary, California, USA. Longfin Smelt are planktivorous forage fish found in estuarine and coastal waters from San Francisco Bay, California to the Aleutian Islands, Alaska (Garwood 2017). This species was once a dominant forage fish in the estuary, even supporting a small commercial fishery prior to the 1970s (Skinner 1962, Moyle 2002); however, this genetically distinct population has collapsed to approximately 1% of its historic (pre-1980) abundance, and details regarding its life history and drivers of population dynamics remain uncertain (Nobriga and Rosenfield 2016).
