Trawl Catch and Species Abundance from the 2019 Gulf of Alaska International Year of the Salmon Expedition

This dataset contains fish species abundance data and species-specific biometrics data collected in the Northeast Pacific Ocean using a midwater trawl net. These data were collected as part of the International Year of the Salmon (IYS) High Seas Expedition conducted in February and March 2019, to further improve the understanding of factors impacting salmon marine winter survival. A total of 64 tows were conducted, and for each tow the total species-specific weight and catch were recorded. Taxonomic records were identified to the lowest taxonomic rank possible. Additionally, for some species some individual biometrics were recorded, such as (fork, total, standard and/or mantle) length, weight, sex and age class. Furthermore for salmonids, DNA samples, otoliths, muscle tissue, scales and liver/gonad data were collected for further analysis in Alaskan and UBC labs. The data collected from the trawl aims to improve our understanding of the food web structure.
