Ecological monitoring of fish on Isla Natividad from 2006 to 2021

This dataset encompasses information about fish transects between 2006 to 2021 in Isla Natividad. Abundances, sex and size of fish can be found in the data set. Also, the dates when the transects were done, the site, the name of the diver, the depth the transect was laid, if the site was a marine reserve or not, if the site is inside a marine protected area or not, the latitude and longitude of the sites, the temperature of the water, the number of transect from where the information was counted, and the species name of the fish counted.

Ecological monitoring is important to collect data of species that inhabit an specific ecosystem. For this data set, we present all the data form 2006 to 2021 on algae, marine invertebrates, fish and uniform point contact at six different sites in Isla Natividad off the coast of Baja California Sur, Mexico. Data was collected once a year by trained divers as a collaborative effort from Stanford University, non-governmental organizations, and fishing cooperative federations. These data provides the abundaces of algae, invertebrates, fish and substrate of Isla Natividad over the spam of 15 years and may be use to assess changes in the ecosystems after shocks such as hypoxic events or marine heatwaves.

本数据集涵盖了2006年至2021年间纳蒂维达岛（Isla Natividad）的鱼类样带调查相关数据。数据集包含鱼类的丰度、性别与体长信息，同时记录了样带调查的实施日期、调查位点、潜水员姓名、样带布设深度、该位点是否为海洋禁渔区（marine reserve）、该位点是否处于海洋保护地（marine protected area）范围内、调查位点的经纬度、水体温度、统计数据对应的样带编号，以及所记录鱼类的物种名称。生态监测对于采集栖息于特定生态系统的物种数据具有重要价值。针对本数据集，我们公开了墨西哥南下加利福尼亚州沿岸纳蒂维达岛6个不同调查位点上，2006年至2021年间藻类、海洋无脊椎动物、鱼类以及均匀点接触（uniform point contact）调查的全部数据。该数据由受过专业训练的潜水员每年采集一次，由斯坦福大学（Stanford University）、非政府组织以及渔业合作联合会共同协作完成。本数据集涵盖了纳蒂维达岛15年间藻类、无脊椎动物、鱼类以及底质的丰度数据，可用于评估诸如低氧事件、海洋热浪等扰动事件发生后该区域生态系统的变化情况。
