摘要

从海草草甸的面积和多样性来看,南邦加地区是具有鱼类生物多样性潜力的地区之一。 从生态学角度来看,海草床是有潜力成为保护地的区域,代表着鱼类资源的可持续性。本研究旨在确定鱼类物种的丰富程度、鱼类组成、丰度、多样性、均匀性和主要鱼类,以及海草覆盖率与邦加南部水域鱼类丰度和生物量的关系。 这项研究将于 2023 年 6 月在邦卡县南部进行,覆盖 4 个站点。海草数据收集的形式为使用二次横断面法收集海草覆盖率,鱼类数据收集的形式为扫面积法(扫)。第 4 站的鱼类物种组成最高,为 Gerres limbatus,占 32.51%,共 79 尾。鱼类丰度值为 822 尾/公顷,鱼类多样性为中等,鱼类均匀度较高,优势指数较低。鱼类的丰度和生物量受海草覆盖率的影响,海草覆盖率越高,该地区鱼类的丰度值和生物量也越高。邦加雪兰莪州是一个拥有巨大生物多样性潜力的州。 槟榔屿是一个具有潜力的地区,它是一个保护区,既能保护生态环境,又能保护野生动物。该项目旨在帮助人们在邦加岛的岛屿上建立起岛屿管理、岛屿组成、岛屿管理、岛屿管理、岛屿管理、岛屿管理和岛屿管理中心,以及岛屿管理和岛屿管理生物群落。 该项目将于 2023 年 6 月在班卡省的 4 个地区实施。该地区的数据收集工作是对该地区的数据收集工作的一个补充,以确保数据的准确性。在这些数据中,共有 243 个个体,包括 Alosidae、Apogonidae、Chaetodontidae、Engraulidae、Gerreidae、鲮科、石鲮科、石鲮科、扁鲮科、鲭科、石鲮科、石鲷科、石鲷科、石鲷科、虎鳞鳅科、伏鳅科、戈壁鳅科、单喙鳅科和雷鳅科。在第 4 阶段,蛙类的比例为 32.51%,个体总数为 79 个。目前,共有 822 个个体/公顷,其中,有的个体数量较少,有的个体数量较多,有的个体数量较少,有的个体数量较多,有的个体数量较少,有的个体数量较多。在这一地区,生物多样性和生物量的适应性都会受到持久性因素的影响,但这并不意味着在这一地区没有持久性因素的影响,也不意味着在这一地区没有生物多样性和生物量的影响。

Hubungan Ikan dengan Padang Lamun di Perairan Bangka Selatan, Kepulauan Bangka Belitung
South Bangka Regency is one of the districts that has the potential for fish biodiversity in seagrass meadows when viewed from its area and diversity.  Seagrass beds are areas that have the potential to be conservation sites from an ecological point of view and represent the sustainability of fish resources. This study aims to determine the richness of fish species, fish composition, abundance, diversity, uniformity and dominating fish as well as the relationship of seagrass cover to the abundance and biomass of fish found in southern Bangka Waters.  The study will be conducted in southern Bangka Regency in June 2023 covering 4 stations. Seagrass data collection in the form of seagrass cover using the quadratic transect method and swept area method (sweep) in fish data collection. The results of the study from the four stations there were 243 individuals including 23 species of fish from 18 families namely Alosidae, Apogonidae, Chaetodontidae, Engraulidae, Gerreidae, Labridae, Lethrinidae, Pinguipedidae, Platycephalidae, Scorpaenidae, Siganidae, Sphyraenidae, Syngnathidae, Terapontidae, Ambassidae, Gobiidae, Monacanthidae and Leiognathidae. The highest fish species composition was found at station 4, namely Gerres limbatus by 32.51% with 79 individuals. The abundance value found was 822 ind/ha and fish diversity was categorized as medium, fish uniformity tended to be high and dominance index was low. The abundance and biomass of fish are influenced by the percentage of seagrass cover, where the higher the percentage value of seagrass cover, the higher the abundance value and biomass of fish in the area. Kabupaten Bangka Selatan merupakan salah satu kabupaten yang memiliki potensi biodiversitas ikan di padang lamun jika dilihat dari luasan dan keanekaragamannya.  Padang lamun adalah kawasan yang berpotensi sebagai tempat konservasi dilihat dari sudut pandang ekologis dan mewakili keberlanjutan sumber daya ikan. Penelitian ini bertujuan untuk mengetahui kekayaan jenis ikan, komposisi ikan, kelimpahan, keanekaragaman, keseragaman dan ikan yang mendominasi serta hubungan tutupan lamun terhadap kelimpahan dan biomassa ikan yang ditemukan di Perairan Bangka bagian selatan.  Penelitian dilakukan di Kabupaten Bangka bagian selatan pada bulan Juni 2023 meliputi 4 stasiun. Pengambilan data lamun berupa tutupan lamun menggunakan metode transek kuadrat dan metode swept area (sapuan) pada pengambilan data ikan. Hasil penelitian dari keempat stasiun terdapat 243 individu mencakup 23 spesies ikan dari 18 famili yaitu Alosidae, Apogonidae, Chaetodontidae, Engraulidae, Gerreidae, Labridae, Lethrinidae, Pinguipedidae, Platycephalidae, Scorpaenidae, Siganidae, Sphyraenidae, Syngnathidae, Terapontidae, Ambassidae, Gobiidae, Monacanthidae dan Leiognathidae.
