Abstract
Pulau Kumbang merupakan bagian dari kawasan konservasi laut Kepulauan Taman Nasional Karimunjawa yang terletak di Perairan Utara Jawa. Pulau tidak berpenghuni ini dijadikan sebagai lahan penangkapan ikan oleh nelayan dari pulau di dekatnya, terutama Pulau Parang. Penelitian ini bertujuan untuk mengkaji kondisi terumbu karang yang berfokus di 4 titik lokasi pada 2 zona kawasan konservasi laut, diantaranya Zona Perikanan Tradisional dan Zona Pemanfaatan Wisata Bahari. Pendataan dilakukan pada 2 kedalaman (5 dan 10 meter) dengan metode yang digunakan untuk mengetahui kondisi tutupan karang yaitu Line Intercept Transect (LIT), keanekaragaman dan kelimpahan ikan karang dengan metode Underwater Visual Census (UVC), dan kelimpahan invertebrata menggunakan metode Belt Transect. Rata-rata tutupan karang di Zona Perikanan Tradisional (59,78%) ditemukan lebih tinggi daripada Zona Pemanfaatan Wisata Bahari (40,61%). Sementara itu, kelimpahan ikan lebih tinggi pada Zona Pemanfaatan Wisata Bahari (14700 individu/ha kedalaman 5m). Famili Pomacentridae (Amblyglyphidodon) menunjukkan kelimpahan yang signifikan dengan 627 individu di salah satu lokasi. Invertebrata yang dilindungi yaitu Kima (Tridacna sp.) ditemukan di semua lokasi, terutama di kedalaman dangkal sebagai invertebrata yang paling melimpah dalam penelitian. Hasil keseluruhan menunjukkan bahwa kondisi terumbu karang di Zona Perikanan Tradisional berada dalam kondisi yang lebih baik daripada Zona Pemanfaatan Wisata Bahari. Kumbang Island is located in the archipelago of Karimunjawa National Park, a Marine Protected Area (MPA) in the Java Sea. Although uninhabited, the island is one of the fishing grounds for local fishers in neighboring islands. This research is aimed to assess the coral reef condition in Kumbang Island, focusing on 2 Sites in 2 MPA Zones: Traditional Fisheries Zone and Marine Tourism Utilization Zone. The assessment was conducted at 2 depths (5 and 10 meters) to observe coral coverage using Line Intercept Transect (LIT), reef fish diversity and abundance with Underwater Visual Census (UVC), and megabenthos abundance using Belt Transect method. The coral cover in the Traditional Fisheries Zone (59,78%) was found to be higher than the Marine Tourism Utilization Zone (40,61%). Meanwhile, the fish abundance was higher in the Marine Tourism Utilization Zone (14700 individual/ha at a depth of 5m). The family Pomacentridae (Amblyglyphidodon) showed a significant abundance with 231 individuals in one of the Sites. The protected Giant Clam (Tridacna sp.) was found in all Sites, mainly in the shallow depth as the most abundant megabenthos in the research. The overall result indicates that the coral reef condition in the Traditional Fisheries Zone is in a better condition than the Marine Tourism Utilization Zone.
甲虫岛是位于爪哇北部水域的卡里蒙加瓦国家公园的海洋保护区的一部分。这个无人居住的岛屿被用作附近一个主要是弯刀岛的渔民的渔场。该研究的目标是评估目前集中在两个海洋保护区的4个地点的珊瑚礁状况,其中包括传统的渔业区和海洋旅游利用区。在2英尺(5米)和10米(10米)的深度上进行了记录,这些方法被用来确定岩礁嘴的情况,即行截取输精管(LIT),用视觉底漆方法进行的鱼类的多样性和丰富,以及用眼部下的方法进行的无脊椎动物数量。传统渔业区(59.78%)的珊瑚覆盖面积被发现高于海洋旅游业使用区(40.61%)。与此同时,在海域的渔场(14700个个体/ha深度5m)的渔场,鱼类的数量也会增加。pomacendae (amblyglydodon)指的是一个地点有627个个体的显著数量。受保护的无脊椎动物Kima (Tridacna sp)被发现在所有地方,特别是在作为研究中最丰富的无脊椎动物的浅层深处。总的结果表明,传统渔区的珊瑚礁状况比海洋旅游利用区好。甲虫岛位于爪哇国家公园的档案馆,这是爪哇海的海洋保护区。尽管遭到了破坏,但这个岛是附近地区fishers的渔场之一。这项研究允许甲虫岛评估珊瑚礁,focusing on the coral reef Island, focusing on 2坐双座:传统渔场和海洋旅游设施区。评估包括2个区域(5和10米),使用眼部介质的内衬线观察珊瑚的覆盖,珊瑚礁鱼的发散性和潜望镜下的积水,和megabenty abundance使用眼部介质的方法。传统渔场的珊瑚封面(59.78%)被发现比海军旅游公用区高40.61%。与此同时,鱼在海洋旅游公用事业区(5m的14700年)游得非常高。有一种意味深长的番茄,其中有231个成员。巨大的蛤蜊被发现在各种各样的环境中,主要存在于研究中最强大的冷冻区。传统渔业与海洋旅游设施区相比,珊瑚礁的存在更加普遍。
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.
