Native Fish

The native fish dataset encompasses observations gathered from diverse regions within New South Wales (NSW), Australia. This dataset is characterised by its point-based structure, consisting of records of native fish occurrences obtained through two primary survey methods: environmental DNA (eDNA) surveys and baited remote underwater video surveys (BRUVs).\r\n\r\nEnvironmental DNA surveys involve the collection and analysis of genetic material shed by aquatic organisms into the surrounding water, providing a non-invasive method for detecting the presence of fish species. Baited remote underwater video surveys (BRUVs) employ underwater cameras equipped with bait to attract fish, allowing for visual identification and documentation of fish species at various depths and locations within aquatic environments.\r\n\r\nEach record in the native fish dataset includes essential information such as species identification, spatial coordinates of observation sites, survey methodology (eDNA or BRUV), and additional environmental parameters such as water quality, habitat characteristics, and vegetation cover. These data offer valuable insights into the distribution, abundance, and diversity of native fish populations across NSW, contributing to scientific research, conservation planning, and ecosystem management initiatives aimed at preserving aquatic biodiversity and ecosystem health.

本土鱼类数据集包含从澳大利亚新南威尔士州（NSW）不同区域收集的观测数据。该数据集具有基于点的结构特征，包含通过两种主要调查方法获取的本土鱼类出现记录：环境DNA（eDNA）调查和诱饵远程水下视频调查（BRUVs）。

环境DNA（eDNA）调查涉及收集和分析水生生物释放到周围水体中的遗传物质，为检测鱼类物种的存在提供了一种非侵入性方法。诱饵远程水下视频调查（BRUVs）使用配备诱饵的水下摄像机吸引鱼类，能够在水生环境的不同深度和位置对鱼类物种进行视觉识别和记录。

本土鱼类数据集的每条记录包含物种鉴定、观测点空间坐标、调查方法（eDNA或BRUV）等关键信息，以及水质、栖息地特征和植被覆盖等额外环境参数。这些数据为了解新南威尔士州（NSW）本土鱼类种群的分布、丰度和多样性提供了宝贵见解，有助于科学研究、保护规划以及旨在保护水生生物多样性和生态系统健康的生态系统管理举措。
