Abstract

Taxonomically, according to the World Register of Marine Species (WORMS), in 2021 the naming of the species Cymodocea serrulata will change to Oceana serrulata (R. Brown) Byng & Christenh. Many studies have been carried out in the Province of the Bangka Belitung Islands, but this type of distribution map has not been presented in detail. Observation of seagrass in the field allows the identification of seagrasses with other types of seagrass. This study aimed to identify morphology, species distribution, and other types of seagrass often associated with seagrass species Oceana serrulata in the Province of the Bangka Belitung Islands. The methods in this study include data collection, identification, and map making. Morphological identification of seagrass species refers to several identification sources. The distribution map of Oceana serrulata is presented from the seagrass data collection that has been carried out. This research uses data from different times, the first was obtained from 2011 and 2022 as primary data. The results of the study explain the identification carried out on the Oceana serrulata has the same characteristics as identification literature. Similarities seen from the identification of leaf morphology which ribbon curved like, parallel leaf veins and triangular shaped sheaths. Other seagrass species that are most often associated with Oceana serrulata are Halodule uninervis and Enhalus acoroides. The map of the distribution of seagrass species Oceana serrulata is found on the islands of Bangka, Belitung, Anak Air, Lepar, Ketawai, Semujur, Kalimambang, Kelayang, Kepayang, Ruk, and Sebongkok islands.

Abstract

Tenggiri adalah salah satu jenis ikan yang memiliki nilai ekonomi yang tinggi dan banyak digemari oleh Masyarakat sebagai bahan baku untuk produk olahan perikanan serta sebagai komoditas ekspor. Kegiatan pemanfaatan perikanan terjadi di pelabuhan, seperti Pangkalan Pendaratan Ikan (PPI) Kurau Kabupaten Bangka Tengah. Namun, kegiatan pemanfaatan yang tidak tepat dapat membahayakan stok tenggiri di masa mendatang, sehingga penelitian ini bertujuan untuk mengetahui nilai CPUE, pola musim penangkapan, ukuran layak tangkap dan daerah penangkapan tenggiri dengan pancing ulur yang didaratkan di PPI Kurau Kabupaten Bangka Tengah. Penelitian ini dilaksanakan pada bulan Februari 2024. Metode yang digunakan adalah deskriptif dengan survei dan observasi. Pengumpulan data dengan metode survei dilakukan dengan wawancara nelayan dan dokumentasi data tahun 2019-2023 dari PPI Kurau, sedangkan pengumpulan data observasi dilakukan dengan mengukur panjang tenggiri secara langsung di lapangan. Hasil penelitian menunjukkan bahwa nilai CPUE tenggiri tahun 2019-2023 mengalami fluktuasi dengan nilai CPUE berkisar 17,18-30,24 kg/trip. Trend CPUE sedikit meningkat (naik) yang menandakan tingkat eksploitasi masih ditahap berkembang, dengan persamaan y = 0,0009x + 21,23 dan R2 = 0,0367. Musim puncak penangkapannya cenderung terjadi antara bulan November-April. Mayoritas tenggiri yang didaratkan memiliki panjang <65 cm, menandakan bahwa tenggiri yang ditangkap masih belum mencapai ukuran layak tangkap. Daerah penangkapan tenggiri berdasarkan hasil wawancara adalah sekitar Laut Natuna Utara dalam Wilayah Pengelolaan Perikanan Negara Republik Indonesia (WPPNRI) 711, seperti Pulau Bebuar, Mugung, Malang, Lemadang, Karang Ular, Karang Kering, Karang Sembilan, Tuing, dan Pulau Gelasa. Kata Kunci : CPUE, Musim Penangkapan, Pancing Ulur, Tenggiri

Abstract

Open access to marine resources causes people to fish without control and ignore conservation and trade status. Theseactivities can cause population decline and population can lead to overfishing.. This is due to the lack of availability ofinformation and scientific data to fishermen regarding the conservation status of fish species. Therefore, this study aimsto identify and determine the conservation status of fish species caught using fixed gillnet fishing gear in PPN Sungailiat.Data collection was carried out in March-May 2024 at the PPN Sungailiat, Bangka Regency. This study uses survey andobservation methods with qualitative descriptive data analysis. The results showed that there were 13 families identified.The main catch in this study contained 12 species and by-catch there were 7 species. The conservation status of fishspecies caught on gillnet fishing gear remains at the Sungailiat VAT according to national regulations based on the Decreeof the Minister of Marine Affairs and Fisheries No. 01 of 2021 with unprotected status. Meanwhile, the conservationstatus of fish species based on IUCN has 6 categories, including 3 species of fish classified as Not Evaluated (NE), 5species classified as Least Concern (LC), 2 species classified as Near Threatened (NT), 2 species classified as Vulnerable(VU), 5 species classified as Endangered (EN) and 2 other species classified as Critically Endangered (CR). Meanwhile,the trade status based on CITES has 2 species of fish classified in Appendix II, namely Rhynchobatus australiae (palmray) and Rhina ancylostomus (barong shark). Based on the results of conservation and trade status, several managementapproaches need to be taken towards fisheries resources so that their populations are maintained.

Abstract

This study aims to analyze the relationship between mangrove density and gastropod abundance in Tuing Beach, Bangka Regency. Mangroves have an important role in coastal ecosystems, providing habitat and food sources for a variety of organisms, including gastropods. Gastropods are a group of mollusks that are commonly found in mangrove ecosystems and play a role in the food chain as decomposers. This study was conducted by survey method at three different research stations, where data on mangrove density and gastropod abundance were collected through the square transect method. The study showed that there was a positive relationship between mangrove density and gastropod abundance at all research stations. Station 2 showed the highest mangrove density with a value of 1.733 ind/ha, while the highest abundance of gastropods was also found at Station 2 with a value of 20,3 ind/m². A simple linear regression analysis showed that mangrove density contributed significantly to the variation in gastropod abundance, with the value of the determination coefficient (R²) varying between 0.732 to 0.904 at all three stations. In addition, environmental parameters such as temperature, pH, salinity, and dissolved oxygen are also measured to understand the environmental conditions that affect the distribution of gastropods. The results of this study can provide important information for sustainable management of mangrove ecosystems, especially in maintaining biodiversity and ecosystem stability in Tuing Beach.
