2021 State of the Environment Report Marine Chapter – Expert Assessment – State and Trend – Shelf (0-200 m) demersal and benthopelagic fish species

《2021年环境状况报告》的海洋章节包含了从海洋数据流中开发的多个专家模板。这一元数据记录描述了专家评估“大陆架（0-200米）底层和深海鱼类物种的状况和趋势”。<br /> * 专家评估报告全文的PDF格式，包括图表（如有提供），可在本记录的“在线资源”部分下载，标题为“2021年专家评估报告-现状和趋势-陆架（0-200米）底层和深海鱼类”*<br /> <br /> ----------------------------------------<br /> <br /> 供专家评估的物种/群落描述<br /> 这项评估包括澳大利亚各地的大陆架（0- 200米）、底层和深海鱼类种群，但试图避免珊瑚礁鱼类（0- 30米）和深海鱼类种群，这些将单独评估。 一些在水深超过30米的水域中出现的珊瑚鱼也包括在本评估中。<br /> <br /> 用于专家评估的数据流<br /> 该评估基于已发表的报告（见参考文献），特别是Gaughan和Santoro（2020）、Patterson等人（2020）和Stewardson等人（2018）。<br /> <br /> ----------------------------------------<br /> <br /> 2021年国有企业评估摘要[详细信息请参见随附的专家评估]<br /> <br /> · 2021 ·<br /> 评价等级：良好<br /> 评估趋势：改进<br /> 置信度：充分<br /> 信心趋势：充足<br /> 可比性：等级和趋势与2016年评估具有一定可比性<br /> · 2016 ·<br /> 评价等级：差<br /> 评估趋势：改进<br /> 置信度：充分的高质量证据或高度共识<br /> 可信度趋势：证据有限或共识有限<br /> 可比性：等级和趋势与2011年评估有一定可比性<br /> <br /> · 2011 ·<br /> 评价等级：很好<br /> 评估趋势：稳定<br /> 置信度：充足的高质量证据和高度共识<br /> 可信度趋势：证据有限或共识有限<br /> <br /> ----------------------------------------<br /> <br /> 2016年以来的变化<br /> 评估等级从“差”（2016年）提高到“好”（2021年），这是基于被列为可持续的鱼类种群百分比的增加。

The Marine chapter of the 2021 State of the Environment (SoE) report incorporates multiple expert templates developed from streams of marine data. This metadata record describes the Expert Assessment "State and Trend of Shelf (0-200 m) demersal and benthopelagic fish species". <br /> ***A PDF of the full Expert Assessment, including figures and tables (where provided) is downloadable in the "On-line Resources" section of this record as "EXPERT ASSESSMENT 2021 - State and Trend – Shelf (0-200 m) demersal and benthopelagic fish species"***<br /> <br /> ----------------------------------------<br /> <br /> DESCRIPTION OF SPECIES/COMMUNITY FOR EXPERT ASSESSMENT<br /> This assessment includes shelf (0–200m), demersal, and benthopelagic fish stocks from around Australia, but attempts to avoid reef fish (0–30m) and pelagic species, which will be assessed separately. Some reef fish occurring in water deeper than 30m are included in this assessment.<br /> <br /> DATA STREAM(S) USED IN EXPERT ASSESSMENT<br /> This assessment is based on published reports (see references), notably Gaughan and Santoro (2020), Patterson et al (2020) and Stewardson et al (2018).<br /> <br /> ----------------------------------------<br /> <br /> 2021 SOE ASSESSMENT SUMMARY [see attached Expert Assessment for full details]<br /> <br /> • 2021 •<br /> Assessment grade: Good<br /> Assessment trend: Improving<br /> Confidence grade: Adequate<br /> Confidence trend: Adequate<br /> Comparability: Grade and trend are somewhat comparable to the 2016 assessment<br /> • 2016 •<br /> Assessment grade: Poor<br /> Assessment trend: Improving<br /> Confidence grade: Adequate high-quality evidence or high level of consensus<br /> Confidence trend: Limited evidence or limited consensus<br /> Comparability: Grade and trend are somewhat comparable to the 2011 assessment<br /> <br /> • 2011 •<br /> Assessment grade: Very good<br /> Assessment trend: Stable<br /> Confidence grade: Adequate high-quality evidence and high level of consensus<br /> Confidence trend: Limited evidence or limited consensus<br /> <br /> ----------------------------------------<br /> <br /> CHANGES SINCE 2016 SOE ASSESSMENT<br /> Assessed grade improved from “poor” (2016) to “good” (2021) based on an increase in the percentage of fish stock classified as sustainable cited reports.
