Fish Species Composition and Diet Information in Lakes of the Arctic Coastal Plain, Alaska, 2011-2013

공공데이터포털

This dataset provides information on fish species composition and their diet information for 16 lakes and 16 ponds at two locations on the central Arctic Coastal Plain, Alaska. In one table, we provide the presence of fish species and the total species count for each lake or pond sampled. This table also includes metrics of surface water connectivity to the stream network. In a second table, stomach content information is provided for fish collected during summer sampling periods (late June to mid-August) over three years (2011–2013). The third table includes stable carbon isotope and stable nitrogen isotope signature data for fish species and snails (the baseline organism) from 16 water bodies at one study location in 2013.

Fish Nutritional Quality, Biomarkers, Communities, and Environmental Data from the Nearshore Beaufort Sea, Alaska, 2021-2023

공공데이터포털

This data release contains information derived from fishing efforts and sampled fish from the nearshore Beaufort Sea, Alaska, 2021-2023, as part of a study investigating red-throated loon productivity and diet. The datasets include six tables comprising 1) catch per unit effort (CPUE) data, 2) field-measured lengths of fish (mm), 3) the energy density (kJ/g) and whole-body energy (kJ) of 16 species of forage-sized fish (≤200 mm), 4) taxonomic details of captured fish, 5) temperature (°C), raw electrical conductivity (μS/cm), and salinity (psu) as recorded by data loggers, and 6) the specifications of surface trawl fishing sets.

Arctic Cisco Stomach Content Data, Prudhoe Bay, August 2009

공공데이터포털

This data set documents the stomach contents of age-0 Arctic cisco (Coregonus autumnalis) captured in Prudhoe Bay, Alaska in August 2009. The analysis of this data was published in von Biela et al. 2013 (Polar Biology 36:137-146, doi:10.1007/s00300-012-1244-x). The data consists of counts of specific zooplankton taxa from individual fish stomachs.
