Plastic ingestion by mesopelagic fishes in the North Pacific Subtropical Gyre
The oceanic convergence zone in the North Pacific Subtropical Gyre acts to accumulate floating marine debris, including plastic fragments of various sizes. Little is known about the ecolog- icalExpand
Global Trophic Position Comparison of Two Dominant Mesopelagic Fish Families (Myctophidae, Stomiidae) Using Amino Acid Nitrogen Isotopic Analyses
The δ15N values of organisms are commonly used across diverse ecosystems to estimate trophic position and infer trophic connectivity. We undertook a novel cross-basin comparison of trophic positionExpand
Carbon export mediated by mesopelagic fishes in the northeast Pacific Ocean
The role of fishes in the global carbon cycle is poorly known and often neglected. We show that the biomass of mesopelagic fishes off the continental USA west to longitude 141W is positively relatedExpand
Acoustic biomass estimation of mesopelagic fish: backscattering from individuals, populations, and communities
Acoustic survey methods are useful to estimate the distribution, abundance, and biomass of mesopelagic fish, a key component of open ocean ecosystems. However, mesopelagic fish pose severalExpand
Abundance and community composition of micronekton across a front off Southern California
Concurrent net and acoustic data were collected across a front off SouthernCalifornia to assess its influence on the abundance, biomass and community com-position of the micronekton. Higher abundanceExpand
The specific gravity of mesopelagic fish from the northeastern Pacific Ocean and its implications for acoustic backscatter
Knowledge of the species present, their morphology, and their size distribution is required to infer biomass from acoustic surveys of fish. The gas content and specific gravity of the body (with gasExpand
Recent collapse of northern anchovy biomass off California
Abstract New estimates of abundance of northern anchovy ( Engraulis mordax ) are developed from California Cooperative Oceanic Fisheries Investigations (CalCOFI) data on egg and larval densities forExpand
Epipelagic and mesopelagic fishes in the southern California Current System: Ecological interactions and oceanographic influences on their abundance
article i nfo We use zooplankton and ichthyoplankton data from the ~60-year CalCOFI time series to examine relationships of mesopelagic (i.e. midwater) fishes in the California Current System withExpand
The export of carbon mediated by mesopelagic fishes in the northeast Pacific Ocean
Author(s): Davison, Peter Charles | Abstract: Mesopelagic fishes are under-studied in relation to their importance in pelagic ecosystems. Traditional sampling methods (trawls and acoustic surveys)Expand
