Southern Surveyor Voyage SS 05/93 Biological Data Overview

This record is an overview entry for biological data collected on Southern Surveyor cruise SS 05/93. This cruise took place in waters east of Bass Strait and off the east, west and southern Tasmanian coasts during 14 July - 25 August 1993, under the leadership of Tony Koslow, Sebastian Rainer and Barry Bruce. Biological data collected on this cruise include photographic and dredge samples of several relatively unfished hills to examine the benthic habitat associated with the orange roughy and oreo dory fishery. Zooplankton and mid-water nekton samples. Extensive biological and distribution data on a wide range of demersal fish species, including SEF quota species. Stomach contents from SEF quota and other abundant fish species were sampled to determine their immediate feeding links and to compare with stable isotope analysis. Samples of fish, plankton and seafloor invertebrates were obtained for stable isotope analysis to provide preliminary data on their position in the community food web. Benthic and epibenthic samples to determine the appropriate intensity and spatial scale for experimental field studies on the effects of trawling on seafloor communities. Video photography of fish behaviour at the mouth of the trawl net. Acoustic data including data from St Helens Hill area to estimate the biomass of orange roughy. Specimens of SEF quota and other species for collaborative studies in other Australian research institutions. Blue grenadier egg and larval samples to assist in planning a future survey of blue grenadier biomass. Please note: This metadata record is a preliminary entry derived from information in the cruise plan and/or cruise report. Individual data types - which may span several cruises - will be indexed separately within this metadata system in due course. - Biological Field Data Sheets recorded during this voyage have been scanned to PDF, and are available (to CSIRO Staff) on-line.

本记录为“南方考察者”号（Southern Surveyor）SS 05/93航次采集的生物数据概述条目。该航次于1993年7月14日至8月25日期间，在巴斯海峡（Bass Strait）东部海域以及塔斯马尼亚州东、西、南沿岸外海开展，由Tony Koslow、Sebastian Rainer与Barry Bruce牵头负责。
本航次采集的生物数据包含多处未受过度捕捞的海山的摄影与拖网采样样本，用于探究与橘棘鲷（orange roughy）和奥里奥鲷（oreo dory）渔业相关的底栖生境；此外还采集了浮游动物与中层游泳生物样本。针对多种底层鱼类（demersal fish），包括SEF配额物种（SEF quota species），采集了大量生物学与分布数据。对SEF配额物种及其他优势鱼类的胃容物进行采样，以明确其直接营养联系，并与稳定同位素分析（stable isotope analysis）结果进行对比。采集鱼类、浮游生物与海底无脊椎动物样本用于稳定同位素分析，以获取其在群落食物网中所处位置的初步数据。采集底栖（benthic）与表底栖（epibenthic）生物样本，以确定拖网捕捞（trawling）活动对海底群落影响的野外实验研究的适宜强度与空间尺度。拍摄了拖网网口处的鱼类行为影像。采集声学数据（包括圣海伦斯海山（St Helens Hill）区域的数据），以估算橘棘鲷的生物量。采集SEF配额物种及其他物种的标本，用于澳大利亚其他科研机构的合作研究。采集蓝鳕（blue grenadier）的卵与幼体样本，以辅助规划未来的蓝鳕生物量调查工作。
请注意：本元数据（metadata）记录为基于航次计划和/或航次报告信息形成的初步条目。后续将在本元数据系统内对可能涉及多个航次的各类数据类型分别进行索引。
