Depressed eastern oyster Crassostrea virginica populations in the northern Gulf of Mexico have been the target of numerous post-Deepwater Horizon restoration projects. These projects primarily have focused on replacing oyster cultch (substrate) to promote spat settlement, increase recruitment, and bolster adult oyster populations. This study assessed the outcomes of six such efforts, which used different cultch types and densities between 2015 and 2022 in three estuaries on the Florida panhandle (Pensacola, St. Andrew, and Apalachicola bays). Total restoration costs for these projects were more than US$14 million.

佛罗里达大河口崩溃的牡蛎种群似乎无法使用传统的养殖方法进行恢复——来自多个系统正在进行的努力的见解

 墨西哥湾北部的弗吉尼亚牡蛎种群数量减少 一直是许多深水地平线后 恢复项目的目标。这些项目主要侧重于更换牡蛎养殖（基质），以促进卵的解决、增加补充和增加成年牡蛎数量。这项研究评估了六项此类努力的结果，这些努力在 2015 年至 2022 年间在佛罗里达狭长地带的三个河口（彭萨科拉湾、圣安德鲁湾和阿巴拉契科拉湾）使用了不同的养殖类型和密度。这些项目的总修复成本超过 1,400 万美元。
