Abstract

Penyu adalah biota yang termasuk kategori hewan dilindungi, karena memiliki tingkat keterancaman punah yang tinggi dari faktor alami maupun antropogenik. Penyu menghabiskan hidupnya di laut lepas dan pergi ke daratan untuk bertelur pada setiap musimnya. Keberhasilan penetasan telur penyu menjadi hal yang penting sebagai upaya untuk menambah populasinya. Penelitian ini bertujuan untuk menganalisis keberhasilan daya tetas telur penyu hijau (Chelonia mydas) serta penyu sisik (Eretmochelys imbricata) di Pulau Mangkai Kabupaten Kepulauan Anambas. Penelitian dilakukan pada tahun 2022 di bagian utara (Pantai Empung) dan selatan Pulau Mangkai (Pantai Pantai Suit, Pantai Skanji dan Pantai Teluk Kado). Penelitian dilakukan dengan melakukan pengamatan pada kondisi pantai pendaratan, jumlah sarang, jumlah telur, probabilitas dan frekuensi penyu bertelur, persentase telur menetas, hatching success dan persentase tukik hidup dan rilis. Hasil penelitian menunjukkan bahwa terdapat dua jenis penyu yaitu penyu hijau (Chelonia mydas) dan penyu sisik (Eretmochelys imbricata) yang melakukan pendaratan di Pulau Mangkai.

阿南巴斯群岛曼凯岛绿海龟（Chelonia mydas）和玳瑁（Eretmochelys imbricata）卵的孵化成功率

海龟被列为受保护动物，因为它们受到自然和人为因素的严重威胁。海龟一生生活在公海中，每个季节都会到陆地上产卵。海龟卵的孵化成功率对增加海龟数量非常重要。本研究旨在分析阿南巴斯群岛芒凯岛绿海龟（Chelonia mydas）和玳瑁（Eretmochelys imbricata）卵的孵化成功率。研究于 2022 年在芒凯岛北部（Empung 海滩）和南部（Suit 海滩、Skanji 海滩和 Teluk Kado 海滩）进行。研究通过观察登陆海滩的状况、巢的数量、卵的数量、海龟产卵的概率和频率、孵化卵的百分比、孵化成功率以及孵化成活并放归的幼龟百分比来进行。结果显示，有两种类型的海龟，即绿海龟（Chelonia mydas）和玳瑁（Eretmochelys imbricata）登陆了芒凯岛。海龟筑巢的概率出现在 8 个月中，6 月份的概率最高（100%）。共有 615 个半自然巢穴和 4 个自然巢穴，其中 6 月份的巢穴数量最多，共有 164 个绿海龟巢穴。发现的龟蛋总数为 55 916 枚，孵化的龟蛋总数为 48 864 枚。孵化成功率平均为 86.27%，孵化出的幼龟成活率平均为 99.2%。在芒凯岛成活并放归的幼龟总数为 48 276 只。海龟是受保护的生物群物种之一，因为它们受到自然和人为因素的严重威胁。海龟终生生活在公海上，每个季节都会上岸产卵。成功孵化海龟蛋对增加其数量至关重要。本研究分析了阿南巴斯群岛芒凯岛绿海龟（Chelonia mydas）和玳瑁（Eretmochelys imbricata）的孵化成功率。研究于 2022 年在芒凯岛北部（Empung 海滩）和南部（Suit 海滩、Skanji 海滩和 Teluk Kado 海滩）进行。研究通过观察巢穴数量、卵数量、海龟产卵概率和频率、孵化卵百分比、孵化成功率、孵化成活率和释放率等条件进行。结果显示，有两种海龟，即绿海龟（Chelonia mydas）和玳瑁（Eretmochelys imbricata）登陆芒凯岛。产卵概率为 8 个月，6 月的产卵概率最高（100%）。共有 615 个半自然巢穴和 4 个自然巢穴，其中 6 月份的数量最多，共有 164 个绿海龟巢穴。发现的龟蛋数量为 55 916 枚，孵化出 48 864 枚龟蛋。孵化成功率平均为 86.27%，孵化成活并放归的幼龟平均比例为 99.2%。芒凯岛上成活并成功放归的幼龟总数为 48 276 只。

期刊介绍： The Journal of Marine Research publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. In the area of biology, studies involving coupling between ecological and physical processes are preferred over those that report systematics. Authors benefit from thorough reviews of their manuscripts, where an attempt is made to maximize clarity. The time between submission and publication is kept to a minimum; there is no page charge.
