Courageous Cruise 016 Biological Data overview, 1977

This record describes the datasets obtained on Courageous Cruise 016. The data were obtained from waters off the southeast and west coasts of Tasmania, in Bass Strait and New South Wales coast in January 1977. Data were obtained from acoustic and trawl surveys of Jack mackerel (Trachurus declivis) and other demersal and pelagic fish including pilchards, redbait, small sharks, whiptail and hake. Length, sex, numbers, biomass and target signal strength were determined. Data on gonad size and state were also obtained. Additional information regarding this dataset is contained in the cruise summary for this voyage.(derived from the cruise report) - Biological Field Data Sheets recorded during this voyage have been scanned to PDF, and are available (to CSIRO Staff) on-line. See the details link under "Stored Media List" (below).本记录描述了勇敢巡航航次016（Courageous Cruise 016）所获取的数据集。该调查数据采集于1977年1月，覆盖塔斯马尼亚东南、西海岸外海域、巴斯海峡以及新南威尔士州沿岸水域。本次调查采用声学与拖网调查方式，针对斜纹竹䇲鱼（Jack mackerel，学名*Trachurus declivis*）及其他近底层、中上层鱼类（包括沙丁鱼、红饵鱼、小型鲨鱼、长尾鳕及无须鳕）开展采样，并测定了鱼类体长、性别、种群数量、生物量以及目标信号强度。同时还获取了鱼类性腺大小与发育状态的相关数据。本数据集的补充信息详见本次航次的航次总结报告（源自航次正式报告）。本次航次期间形成的生物野外记录表已扫描为PDF格式，仅可向澳大利亚联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation, CSIRO）员工在线查阅。相关详情可参见下方"存储介质列表（Stored Media List）"项下的详情链接。
