The present study was carried out in the marine area of Stratoni, Greece, where two seahorse species are present (Hippocampus hippocampus and H. guttulatus). Two surveys were conducted (September 2016, May 2019) to gather information regarding seahorse species' abundance, distribution and habitat characteristics. Four different seahorse natural and artificial habitat types were identified. Results revealed that the abundance of H. hippocampus was relatively high, especially at sites with artificial structures, while the presence of H. guttulatus was rare. Data collected can provide baseline information for future population assessments.

地中海东北部半封闭海域（Stratoni，北爱琴海）海马种群密度、结构和栖息地利用的实地研究

本研究是在希腊斯特拉托尼海域进行的，那里有两种海马物种（海马海马和海马海马）。进行了两次调查（2016 年 9 月，2019 年 5 月）以收集有关海马物种的丰度、分布和栖息地特征的信息。确定了四种不同的海马自然和人工栖息地类型。结果表明，海马海马的丰度相对较高，尤其是在人工结构的地点，而海马海马的存在则很少见。收集的数据可为未来的人口评估提供基线信息。
