In the past 100 years since birth of fisheries oceanography, research on early life history fishes, particularly larval stage, has been extensive, and much progress made in identifying mechanisms by which factors such as feeding success, predation, or dispersal can influence survival.However, recent years, study fish undergone a major and, arguably, necessary shift, resulting growing body aimed at understanding consequences climate change other anthropogenically induced stressors.Here, we...
We present the design and at-sea results from a hybrid marine robot called Mesobot that can actively track midwater phenomena.
Abstract Variations in larval fish growth rates are largely the result of variability biotic and abiotic characteristics feeding environment experienced by each individual. An assessment an individual's overall success (i.e. accumulation utilizable organic matter) can best be achieved at time capture when relationships among environment, short-term as defined gut content long-term accumulated contrasted. Here, we investigated between average growth, success, individual across a range taxa...
Abstract The American sand lance ( Ammodytes americanus , Ammodytidae) and the Northern A. dubius are small forage fishes that play an important functional role in Northwest Atlantic Ocean (NWA). NWA is a highly dynamic ecosystem currently facing increased risks from climate change, fishing energy development. We need better understanding of biology, population dynamics to inform relevant management, adaptation conservation efforts. To meet this need, we synthesized available data on (a)...
Animal biodiversity in the ocean’s vast mesopelagic zone is relatively poorly studied due to technological and logistical challenges. Environmental DNA (eDNA) analyses show great promise for efficiently characterizing could provide new insight into presence of species, including those that are missed by traditional net sampling. Here, we explore utility eDNA identifying animal taxa. We describe results from an August 2018 cruise Slope Water off northeast United States. Samples analysis were...
Mesopelagic fishes are an important component of the world’s oceans in terms their abundance, biomass, and ecosystem function. These contributors to biological carbon pump via feeding behaviors, whereby they facilitate transfer from shallow waters deep sea. Several species undertake diel vertical migration, shallower at night moving deeper during day. This process actively expedites downward flux carbon. However, budgets climate models require accurate information regarding depth...
Coral reef ecosystems are now commonly affected by major climate and disease disturbances. Disturbance impacts typically recorded using benthic cover, but this may be less reflective of other ecosystem processes. To explore the potential for water-based disturbance indicators, we conducted a 7-year time series on US Virgin Island reefs where examined cover water nutrients microorganisms from 2016 to 2022, which included two disturbances: hurricanes Irma Maria in 2017 stony coral tissue loss...
Monthly plankton sampling across the Straits of Florida (SOF) allowed for a thorough investigation feeding ecologies four taxa larval tunas (family Scombridae, tribe Thunnini) and horizontal vertical distributions tuna larvae their dominant prey. Before piscivory, Thunnus spp. had mixed diet crustaceans appendicularians, whereas skipjack ( Katsuwonus pelamis ), little tunny Euthynnus alletteratus Auxis displayed highly selective nearly exclusive on appendicularians. The availability both...

At the end of their life cycle, American eel ( Anguilla rostrata ) migrate to Sargasso Sea from freshwater habitats along east coast North America in order spawn planktonic eggs. The eggs develop into larvae that then have reach estuarine and nursery within approximately first year life. A coupled biological—physical model was used study how potential behavioral adaptations influence ability near‐coastal waters. Specifically, several larval swimming behaviors were investigated, including...
Abstract The mesopelagic zone covers a vast expanse of the World’s oceans and contains some most abundant vertebrates on planet. This midwater region is central to transfer energy carbon between atmosphere deep, yet there are large knowledge gaps in our understanding life history its animals. Here we synthesize current state research age, growth, reproduction fishes, basic biological information fundamental population dynamics species this ecosystem. Collectively, two-thirds fishes has been...
Abstract The ocean’s twilight zone is a vast area of the global ocean that lies between sunlit surface waters and perpetually dark midnight zones, covering depths from ∼200 to 1000 m. Recent work in (or mesopelagic) has revealed unexpected biomass diversity may not only challenge scientific understanding marine systems but also provide new largely untapped resource for fisheries harvest.

Pop-up satellite archival transmitting (PSAT) tags are capable of storing high-resolution behavioral and environmental information for extended periods time (approximately 1 year), rendering them especially valuable studying highly mobile species. In this review, we synthesize published PSAT data to understand the biophysical drivers that influence movements billfishes (families Xiphiidae Istiophoridae). To date, over 1,080 PSATs have been deployed on billfishes, with individuals...

Mesopelagic fishes may contribute substantially to marine carbon transport by consuming organic near the surface at night and releasing it in mesopelagic zone during day. However, magnitude uncertainties associated with this are not well understood; fish-mediated flux estimates range from less than 1% greater 30% of biologically-driven export out epipelagic zone. While total fish biomass is an important source uncertainty, information on bioenergetics movement might also limit precision...
Fish diversity and ecology in the ocean’s mesopelagic zone are understudied compared to other marine regions despite growing interest harvesting these potential resources. Otoliths can provide a wealth of taxonomic life history information about fish, which help fill knowledge gaps; however, there has been relatively little research date on otoliths species. Here, species-specific image library was assembled sagittal from 70 fishes belonging 29 families collected western North Atlantic...
