Abstract

Three specimens of Plectranthias retrofasciatus Fourmanoir and Randall, 1979 and one specimen of P. randalli Fourmanoir and Rivaton, 1980 were collected by first author from fish market, Bitung, North Sulawesi on June and September 2010. The specimens were deposited at LBRC-F, the reference collection of LIPI Bitung, Technical Implementation Unit for Marine Biota Conservation, Research Centre for Oceanography, Indonesian Institute of Sciences, Bitung, Indonesia. Plectranthias retrofasciatus is closely related to P. megalophthalmus and P. knappi, in sharing some morphological characters as snout length and interorbital width, while P. randalli differs to other species by having a moderate deep body proportion. Initially these species known only from New Caledonia for P. retrofasciatus and Chesterfield Islands and southern Taiwan for P. randalli respectively. The two species of anthiine fishes collected from Bitung, Indonesia bringing the total number of species of this genus known in Indonesia to six.

Abstract

Tuna is the single important export fishery commodity in Indonesia, which The Banda Sea is one of the important tuna fishing ground in which it belongs to fisheries management area (FMA) 714. More recently, some areas of the Banda Sea have been preserved for tuna conservation since January 2015 because it is indicated as the spawning area. Despite the conservation area has been enacted, information on the distribution of tuna larvae as a key variable for establishing conservation area in the Banda Sea is very limited. This study aims to provide the information on the tuna larvae encompassing the spatial distribution and tuna larval development stage as an important input to establish tuna conservation area. Tuna larvae data were collected from several surveys that were done in the Banda Sea over 4 decades. Those study consisted of 21 surveys by using three types of gears to collect tuna larvae sample. Total of 143 stations have been sampled from these surveys and tuna larvae were found in 57 stations. The body length of larvae tuna was 7.36 ± 0.33 mm (mean ± SE). Overall, tuna larvae found in the Banda Sea were in the pre-flexion, flexion, and post-flexion stage. Meanwhile, tuna larvae in pre-flexion stage found in the nearshore area. We concluded this study result supported the hypothesis that tuna may spawn in the Banda Sea. Therefore, more studies on tuna larvae need to be conducted to clarify properly the Banda Sea is an important tuna conservation location.

Abstract

Ekosistem mangrove memiliki berbagai manfaat dari aspek ekologi, sosial ekonomi, hingga aspek fisik. Mangrove juga menyediakan jasa ekosistem yang dapat diperoleh secara langsung maupun secara tidak langsung oleh manusia. Aspek sosial dan ekologis di dalam ekosistem mangrove merupakan sebuah kesatuan yang tidak terpisahkan didalam pendekatan pengelolaannya. Penelitian ini bertujuan untuk menganalisa interaksi sistem sosial ekologi (SES), dan memformulasikan konektivitas SES untuk perbaikan tata kelola ekosistem mangrove di Desa Teluk Awur, Kabupaten Jepara, Provinsi Jawa Tengah. Penelitian dilakukan pada bulan Mei 2023. Pengambilan data sosial ekologi dilakukan dengan menggunakan metode participatory mapping dan participatory data collection yang meliputi observasi lapangan, wawancara, dan focus group disscusion (FGD). Hasil penelitian menunjukkan terdapat hubungan yang erat dari empat variabel SES yang terdiri dari Resource Unit (RU), Resources System (RS), Resources Actor (RA) dan Resources Governance (RG). Berdasarkan analisa jejaring hubungan antar variabel ditemukan bahwa, interaksi SES ekosistem mangrove di Desa Teluk Awur sangat dipengaruhi oleh Resources Actor. Terdapat 17 interaksi RA dengan 12 diantaranya interaksi yang memengaruhi. Sedangkan Resource Unit (RU) merupakan yang paling banyak dipengaruhi sebagai hubungan timbal balik satu sama lain. Hasil konektivitas SES didapatkan 24 konektivitas antar parameter di ekosistem mangrove Desa Teluk Awur. Interaksi antar parameter paling tinggi adalah pada parameter RA sebesar 50%. Mempertimbangkan hasil interaksi dan konektivitas antar variabel SES, maka perlu adanya rancangan strategi pengelolaan berfokus pada Resources Actor untuk mendukung keberlanjutan ekosistem mangrove di Desa Teluk Awur, Kabupaten Jepara, Provinsi Jawa Tengah. Title: Social-Ecological System Interaction of Mangrove Ecosystem, in Coastal Area Teluk Awur Village, Jepara Regency, Central Java Province  The mangrove ecosystem offers various ecological, socio-economic, and physical benefits, providing services that directly or indirectly benefit humans. Both social and ecological aspects in the mangrove ecosystem are interconnected and should be managed in unison. This research aims to analyze the interaction of social-ecological systems (SES), and formulate SES connectivity for improving mangrove ecosystem management in Teluk Awur Village, Jepara Regency, Central Java Province. The research was conducted in May 2023, involved the use of participatory mapping and participatory data collection, including field observations, interviews, and Focus Group Discussions (FGD). The research findings highlight the close relationship between four SES variables consisting of resource unit (RU), resource system (RS), resources actor (RA), and resources governance (RG). Network analysis revealed that SES interaction in Teluk Awur Village was significantly influenced by resource actor (RA) with 17 interactions observed, with 12 of which were influential. Additionally, reciprocal relationships were found to have the most impact on the Resource Unit (RU). The results of SES connectivity depicted 24 connections between parameters in the mangrove ecosystem in Teluk Awur Village, with the highest interaction observed for the RA parameter at 50%. Considering these findings, it is essential to develop a management strategy that prioritizes resource actors to ensure the sustainability of the mangrove ecosystem in Teluk Awur Village.
