RECOVER MAP 3.3.3.6 Oyster Monitoring Network (All Coasts)

In 2019, all oyster monitoring for the Northern Estuaries (the St. Lucie Estuary, Loxahatchee Estuary, and Caloosahatchee Estuary) were consolidated under a single principal investigator with Florida Fish & Wildlife Conservation Commission. In previous years, monitoring on the west coast (Caloosahatchee) was under contract with Florida Gulf Coast University. This dataset includes files for the oyster monitoring network post-2019. The primary objective of this effort is to implement a long-term monitoring program for Crassostrea virginica in southeast and southwest Florida. Five aspects of oyster ecology are being monitored; condition (as measured by condition index), spatial and size distribution patterns of adult oysters, distribution and frequency patterns of the oyster diseases Perkinsus marinus (dermo) and (on the east coast only) Haplosporidium nelsoni (MSX), reproduction and recruitment, and juvenile oyster growth and survival. A baseline for oysters in each estuary is being established by mapping the existing distribution of reefs/beds, and density of living oysters (per square meter). Historical distributions, where available are being used to assist in identifying areas which may have suitable habitat conditions for reestablishment, given predictive changes in the salinity regime. At five year intervals during CERP implementation, a map of the area including size distribution, density of living oysters, and height of the oyster reef, whenever possible, will be prepared.2019年，北河口片区（含圣露西河口、洛克斯哈奇河口与卡洛萨哈奇河口）的全部牡蛎监测工作统一由佛罗里达鱼类与野生动物保护委员会(Florida Fish & Wildlife Conservation Commission)的一名首席研究员统筹负责。此前数年，西海岸片区（卡洛萨哈奇河）的牡蛎监测工作曾与佛罗里达海湾海岸大学(Florida Gulf Coast University)签订委托合同开展。本数据集涵盖2019年之后的牡蛎监测网络相关文件资料。 本项目的核心目标是为佛罗里达东南部与西南部的美洲牡蛎(Crassostrea virginica)建立长期监测计划。本次监测覆盖牡蛎生态学的五大维度：以条件指数衡量的牡蛎健康状况、成体牡蛎的空间分布与尺寸分布格局、牡蛎致病菌帕金虫(Perkinsus marinus，俗称dermo病)以及（仅东海岸开展监测的）尼氏单孢子虫(Haplosporidium nelsoni，俗称MSX病)的分布与流行频率、繁殖与种群补充情况，以及幼体牡蛎的生长与存活状态。 研究团队将通过绘制各河口现有牡蛎礁/床的分布范围与活体牡蛎密度（单位：每平方米），为当地牡蛎种群建立基线数据。若可获取历史分布记录，将结合盐度格局的预测变化，辅助识别具备适宜栖息地条件、可开展牡蛎种群复育的区域。在大沼泽地综合修复计划(CERP)实施期间，每五年将尽可能编制涵盖区域内牡蛎尺寸分布、活体牡蛎密度与牡蛎礁高度的专项地图。
