资源简介:

Raw increment measurements and biological data for 4318 (of 6143) fish from fishing areas EBS and ETAS. This subset represents ~74% of increment data used in analyses. The full data set has not been published as it underpins commercially sensitive stock assessments and is held by CSIRO in confidence on behalf of AFMA. Requests for the full data set will be considered on a case by case basis and must be directed to Dr David Smith, Research Director Marine Resources & Industries, CSIRO Oceans & Atmosphere Flagship. David(dot)C(dot)Smith(at)csiro(dot)au. Area: fishing area; FishID: unique identifier for each individual; Sex: M or F; Gear:otter trawl (OT), Danish seine (DS) or unknown; Capyear: capture year; Capmonth: capture month; Floorlength: fish length (cm) rounded down to the nearest whole number; AdjAge: adjusted fish age, based on increment count, otolith edge type, date of capture and the species’ nominal birthday (1 Jan). This is the age-at-capture variable in the paper, and is a fish’s age in whole years; DeciAge: decimal age based on date of capture in relation to birth date; Radius: otolith radius along measuring transect in mm; YOB: year of birth, or year class. Year: calendar year in which a given increment was deposited; Age: age in years corresponding to a given increment; Increment: width of otolith annuli in mm

本数据集涵盖取自EBS与ETAS两个捕捞区域的6143尾鱼类中的4318尾的原始耳石轮纹测量数据与生物学相关数据。该子集约占本研究分析所用轮纹数据总量的74%。完整数据集尚未对外公开,因其支撑了具有商业敏感性的渔业资源评估工作,现由澳大利亚联邦科学与工业研究组织(CSIRO)代表澳大利亚渔业管理局(AFMA)保密保管。如需申请获取完整数据集,将按个案逐一审核,相关请求请发送至澳大利亚联邦科学与工业研究组织海洋与大气旗舰项目海洋资源与产业研究主任David Smith博士,邮箱地址为David.C.Smith@csiro.au。 各变量详细说明如下: 1. 区域(Area):鱼类的捕捞区域 2. 鱼类唯一标识(FishID):单尾鱼类的唯一识别编号 3. 性别(Sex):雄性(M)或雌性(F) 4. 作业渔具(Gear):双拖网(otter trawl, OT)、丹麦围网(Danish seine, DS)或未知类型 5. 捕获年份(Capyear):鱼类的捕获年份 6. 捕获月份(Capmonth):鱼类的捕获月份 7. 实测体长(Floorlength):鱼类体长,单位为厘米,已向下取整至整数 8. 校正年龄(AdjAge):基于耳石轮纹计数、耳石边缘类型、捕获日期以及该物种的名义生日(1月1日)计算得到的校正后鱼类年龄。此为该论文中使用的捕获时年龄变量,以完整年份表示鱼类年龄 9. 十进制年龄(DeciAge):基于捕获日期与出生日期的相对关系计算得到的十进制年龄 10. 耳石半径(Radius):沿测量断面获取的耳石半径,单位为毫米 11. 出生年份(YOB):鱼类的出生年份或世代组 12. 沉积年份(Year):单条耳石轮纹沉积的公历年份 13. 对应年龄(Age):与单条耳石轮纹对应的鱼类年龄,单位为年 14. 轮纹宽度(Increment):耳石年轮的宽度,单位为毫米
