ABSTRACT: Shellfish growers routinely observe fish and invertebrates interacting with their aquaculture gear. To quantitatively assess these interactions, underwater action cameras (GoPro®) were used to document fish and invertebrate activity in and around floating oyster bags, cages, and a natural marsh habitat on an oyster farm in the Little Egg Harbor region of Barnegat Bay, New Jersey, USA, in 2018. A free and open-source event-logging software was used to analyze video files. A total of 21 species from 4 phyla were identified across all days and sites. Nekton were quantified from continuously recorded video using the MaxN abundance metric, defined as the maximum number of individuals of a given species present within each 1 min segment of video. Species of both ecological and economic importance in the local ecosystem used the 3 intertidal habitats. Abundance and community composition observed around oyster cages differed from that around floating oyster bags and marsh edge; the latter 2 habitats were not significantly different. Juvenile fish were frequently observed, suggesting that the oyster farm may provide similar natural history functions as other natural marsh habitat.

鱼眼：记录贝类养殖场作为美国新泽西州海洋栖息地的可访问工具

摘要：贝类养殖者经常观察鱼类和无脊椎动物与其水产养殖设备的相互作用。为了定量评估这些相互作用，水下运动相机 (GoPro®) 被用于记录新州巴内加特湾小蛋港地区牡蛎养殖场的漂浮牡蛎袋、网箱和天然沼泽栖息地内和周围的鱼类和无脊椎动物活动。美国泽西岛，2018 年。使用免费的开源事件记录软件来分析视频文件。在所有天数和地点共鉴定了来自 4 个门的 21 个物种。使用 MaxN 丰度指标从连续录制的视频中量化 Nekton，该指标定义为每 1 分钟视频片段中存在的给定物种的最大个体数。在当地生态系统中具有生态和经济重要性的物种使用了 3 个潮间带栖息地。在牡蛎笼周围观察到的丰度和群落组成与漂浮的牡蛎袋和沼泽边缘不同；后两个栖息地没有显着差异。经常观察到幼鱼，这表明牡蛎养殖场可能提供与其他天然沼泽栖息地类似的自然历史功能。
