Soela Voyage SO 2/88 Biological Data Overview

This record is an overview entry for biological data collected on Soela cruise SO 2/88. This cruise took place in waters east of Portland, Victoria and in waters off the west, south and east coasts of Tasmania during 15 March - 8 April 1988, under the leadership of Cathy Bulman. Biological data collected on this cruise include catches and catch rates of orange roughy including other fish from demersal and pelagic tows. Biological information on 2078 fish and length frequency by sex on several hundred additional fish. Other samples including 180 gonad samples for histology. 49 whole ovaries for fecundity studies (NSW Fisheries). 94 samples of ovary tissue for genetic studies. 110 liver, heart and muscle tissue samples (University of Tasmania). 90 whole fish for stock discrimination studies (University of NSW). 87 viscera samples (University of Queensland) and 40 swimbladders (N. Elliott, CSIRO). Over 2014 sharks, Centroscymnus crepidater was the most abundant species on the west coast of Tasmania and Deania calcea was most abundant on the east coast of Tasmania. Majority of sharks were length frequencied by sex, and biologicals done on selected adults. Samples of about a dozen juvenile Jackass morwong of the required year class and several boxes of adults. Crustaceans from two pelagic tows. GPS survey data from the St Patricks Head ground to compare with the same ground during the 1987 Soela cruises. Specimens for taxonomy and photographic records.(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.

本记录为Soela航次SO 2/88所采集生物数据的概述条目。该航次于1988年3月15日至4月8日期间开展，作业区域涵盖维多利亚州波特兰以东海域，以及塔斯马尼亚州西、南、东三侧沿岸海域，由Cathy Bulman担任领队。本航次采集的生物数据包括橘棘鲷（orange roughy）及其他鱼类的渔获量与单位捕捞努力量渔获量，数据源自底拖网与水层拖网采样；包含2078尾鱼类的生物学信息，以及数百尾额外鱼类的按性别分类体长频率数据。其他采样样本包括：用于组织学研究的180份性腺样本；用于繁殖力研究的49份完整卵巢样本（新南威尔士州渔业局，NSW Fisheries）；用于遗传学研究的94份卵巢组织样本；塔斯马尼亚大学提供的110份肝脏、心脏与肌肉组织样本；新南威尔士大学提供的90份完整鱼类样本（用于种群区分研究）；昆士兰大学提供的87份内脏样本，以及澳大利亚联邦科学与工业研究组织（CSIRO）N. Elliott提供的40份鳔样本。本次航次共采集超2014尾鲨鱼样本，塔斯马尼亚州西海岸以铠鲨（Centroscymnus crepidater）为优势物种，东海岸则以长吻角鲨（Deania calcea）最为常见；多数鲨鱼样本完成了按性别划分的体长频率统计，并对选定的成体开展了生物学分析。此外还采集了约12尾对应世代幼体傻鲈（Jackass morwong）样本及多盒成体样本、两份水层拖网采样获得的甲壳类样本，以及圣帕特里克角海域的GPS勘测数据，用于与1987年Soela航次对该海域的勘测结果进行对比。另有用于分类学研究与影像记录的标本（数据源自航次报告）。本次航行期间记录的生物野外数据记录表已扫描为PDF格式，可在线供CSIRO工作人员查阅，详细信息请查看下方"存储介质列表"下的链接。
