Stomach contents of Salmonids caught in the Northeastern Pacific Ocean from from 10 May 1958 to 24 August 1958 (NODC 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.

本报告系既往数据报告的延伸，涵盖加拿大探捕渔船在公海开展鲑鱼捕捞的相关数据。本次捕捞作业采用不同网目规格的刺网（gillnet）进行，作业位点如图1所示。本次捕捞的时段为1958年5月10日至1958年8月24日。所获渔获均经急冻处理后存放于冷藏箱内，运回基地实验室以供后续检测分析。本报告对每尾解冻后的渔获样本的体长、体重、性别、性腺成熟度及胃容物进行了制表统计。此外，本报告还收录了各捕捞位点的配套数据，包括所使用的渔具类型、作业水深、表层水温、盐度（salinity）以及海洋学分区（oceanographic domain）。
