Stomach contents of Salmonids caught in the Northeastern Pacific Ocean from 1958-05-10 to 1958-08-24 (NCEI Accession 7200236)
The present report is an extension of earlier data reports embodying data related to high sea salmon fishing by Canadian exploratory fishing vessels. The catches were made by gillnetting with nets of various mesh size at the positions shown in Figure 1. The period of fishing was from May 10 1958 to August 24 1958. The catches were quick-frozen and held in cold storage boxes for examination at the base laboratory. In this report the length, weight, sex, and maturity, and stomach contents are tabulated for each of the fresh-thawed fish. Also, included are data for each fishing position showing gear fished, depth of fishing, surface temperature and salinity, and oceanographic domain.

Pacific salmon survey from research vessel Hokko Maru in the North Pacific from 2023-07-18 to 2023-07-31, cancelled science program (NCEI Accession 0281868)
공공데이터포털
This cruise was dedicated to salmon survey in the North Pacific, but its scientific program was cancelled due to COVID-19 outbreak on board of the ship on the way to the Bering Sea. No data are expected. Original cruise plans are as follows. Pacific salmon (Oncorhynchus spp.) is one of the most important fishery resources in the North Pacific. Japanese research vessels have monitored the condition of Pacific salmon stocks since 1952. The current R/V Hokko maru was launched in 2004 and the salmon research cruise using a surface trawl in the summer Bering Sea has been carried out since 2007. The main objective for this cruise is to conduct the annual monitoring survey for Japanese chum salmon (O. keta) stocks in the Bering Sea known as their major feeding ground. A positive correlation between annual CPUE of immature chum salmon in each research cruise and a subsequent harvest along Japanese coasts of the corresponding blood-year stocks has found in most cases to date, suggesting the possibility to predict future resource conditions. The annual monitoring survey includes the collection of data on physical oceanography, trophic interactions among zooplankton, salmonids, and organisms at higher trophic levels, and genetic analysis of stock composition of chum salmon.
