摘要

由于自然和人为压力,东部牡蛎(Crassostrea virginica)的数量在历史上一直在下降。作为回应,牡蛎礁已经用许多不同的方法建立起来。这项研究利用从当地餐馆回收的牡蛎壳建造的潮间带珊瑚礁,提供牡蛎定居基质、与珊瑚礁相关的动物栖息地,以及防止沼泽侵蚀的屏障。本研究的目的是确定德克萨斯州加尔维斯顿湾斯威特沃特湖五个不同珊瑚礁上的牡蛎种群特征在四年(2016-2019年)内是如何变化的,第二个目的是研究飓风哈维过后牡蛎种群的反应。在研究期间,每年夏天对五个不同的珊瑚礁进行采样,每个珊瑚礁去除五个袋子,以确定牡蛎的丰度和大小。在这三年的研究中(2017年至2019年),我们还量化了牡蛎吐口水对珊瑚礁的补充。牡蛎的数量和大小(壳高)随年份和珊瑚礁数量的变化而变化,而飓风哈维过后,牡蛎的数量明显减少,然后又恢复到风暴前的水平。我们的研究结果进一步强调了放置防波堤式珊瑚礁的重要性,因为甜水湖内的流体动力学似乎影响了单个珊瑚礁中牡蛎的丰度和大小。虽然由于斯威特沃特湖和加尔维斯顿湾之间的狭窄开口,形成的珊瑚礁的幼虫流入量有限,但这种有限的连通性似乎阻止了飓风哈维淡水流入造成的大规模死亡。因此,建造牡蛎礁的项目应考虑当地和区域景观因素,以确保牡蛎种群的长期成功和对自然灾害的抵御能力。

Localized Placement of Breakwater Reefs Influences Oyster Populations and Their Resilience after Hurricane Harvey
Populations of the eastern oyster (Crassostrea virginica) have been historically declining due to both natural and anthropogenic stressors. In response, oyster reefs have been created with many different approaches. This study utilized intertidal reefs constructed with oyster shells recycled from local restaurants to provide oyster settlement substrate, reef-associated faunal habitat, and a barrier to prevent marsh erosion. The objective of this study was to determine how oyster population characteristics changed over four years (2016–2019) on five different reefs within Sweetwater Lake, Galveston Bay, Texas, with a secondary objective to examine how oyster populations responded after Hurricane Harvey. Over the study period, five different reefs were sampled each summer by removing five bags per reef to determine oyster abundance and size demography. For the three years of the study (2017–2019), we also quantified oyster spat recruitment to the reefs. Oyster abundance and size (shell height) varied interactively by year and reef number, whereas oyster recruitment was significantly lower following Hurricane Harvey and then returned to pre-storm levels. Our results further highlight the importance of reef placement for breakwater-style reefs, as it appears the hydrodynamics within Sweetwater Lake influenced both oyster abundance and size among individual reefs. While the created reefs receive limited larval influx due to the narrow opening between Sweetwater Lake and Galveston Bay proper, this limited connectivity seemed to prevent mass mortality from the freshwater influx from Hurricane Harvey. Therefore, projects creating oyster reefs should consider local and regional landscape factors for the long-term success of oyster populations and robustness to natural disasters.
