Examining fishing activities based on in-situ tracking and oceanographic characteristics in Aru Sea and surroundings

Fisheries activites and oceanographic conditions have a strong relationship. Understanding the complex interplay between fisheries and oceanographic conditions is essential for effective fisheries management. The aim of this research is to analyze the in-situ fishing activities with oceanographic conditions in the Fisheries Management Area (FMA) or WPP-NRI 718 located in the Aru Sea and its surroundings. The main data source is from open global data ship tracking and oceanographic conditions from satellite data. In general, fishing is conducted around the waters of Aru Island. The fishing grounds are strongly influenced by a combination of environmental factors, including sea surface temperatures, chlorophyll-a (Chlor-a) concentrations, sea surface height, and current velocities. A decrease in fishing patterns around Aru Island waters occurs in the eastern season, where fishing tends to occur in the western region (near Timor-Leste). Based on the oceanographic conditions, fishing tends to occur in regions with warmer conditions ranging from 27 to 29 °C, moderate Chlor-a (1.02–3.01 mg/m3), a relatively high surface height (0.17–0.32 m), and slow surface currents.

Vicariant speciation resulting from biogeographic barriers in the Australian tropics: The case of the red-cheeked dunnart (Sminthopsis virginiae).

Global biodiversity loss continues unabated, and in Australia, the rate of recent mammal extinctions is among the worst in the world. Meanwhile, the diversity among and within many endemic mammal species remains undescribed. This information is crucial to delineate species boundaries and thus inform decision-making for conservation. Sminthopsis virginiae (the red-cheeked dunnart) is a small, dasyurid marsupial found in four disjunct populations around the northern coast of Australia and New Guinea. There are three currently recognized subspecies, each occupying a distinct geographic location. Sminthopsis v. virginiae occurs in Queensland, S. v. rufigenis is distributed across New Guinea and the Aru Islands, and S. v. nitela has populations in the Top End of the Northern Territory and the Kimberley region of Western Australia. Previous molecular work has suggested the current subspecies definitions are not aligned with DNA sequence data, though the sampling was limited. We undertook a comprehensive genetic and morphological review of S. virginiae to clarify relationships within the species. This included mitochondrial (CR, 12S, and cytb) and nuclear (omega-globin, IRBP, and bfib7) loci, and morphometric analysis of skulls and whole wet-preserved specimens held in museums. Maximum Likelihood and Bayesian phylogenetic analyses resolved samples into two distinct clades, demarcated by the Gulf of Carpentaria in Australia's north. Sminthopsis. v. nitela was consistently separated from S. v. virginiae and S. v. rufigenis, based on the overall body and skull size and craniodental features, while S. v. virginiae and S. v. rufigenis were more difficult to distinguish from each other. Thus, we redescribed S. virginiae, recognizing two species, S. nitela (raised from subspecies) and S. virginiae (now comprising the subspecies S. v. virginiae and S. v. rufigenis). This study highlights the importance of recognizing cryptic mammal fauna to help address the gap in our knowledge about diagnosing diversity during a time of conservation crisis.

“Pearl Rush” and the Construction of Australian Imagination of Aru Islands, 1869-1937

In the early 20th century, the Aru Islands emerged as an economic centre in Eastern Indonesia’s lesser known region. Australian pearling industry entry into its maritime zone created the “Pearl Rush”. This western-mode of natural exploitation shaped Aru’s conception as a thriving pearling centre. This image of Aru was therefore a direct result of a constructed imagination reinforced by the active Australian pearling zone. Movement of Australian mariners and pearling fleets influenced the public views of the region, as reflected in the Australian newspapers and popular magazines. Such views connected the Aru Islands’ image into the greater “Pearl Zone” of North and Western Australian cities. This paper examines how Australia’s views of Aru’s natural resources impacted and shaped the understanding of the islands’ commercial role and it will highlight the role of the pearling industry in creating the allure of imagined valuable resources, which paved the way for its exploitation.

Single Bale-Bale Technology: Sustainable Utilization of Flying Fish Eggs in the Waters of the Aru Islands, Indonesia

The waters of Eastern Indonesia constitute a potential area for the utilization of flying fish eggs. The capture of fish eggs relies on the behavior of parent fish that deposit their eggs on floating objects at the sea surface. The technology is known by the name drifting FAD or its local name, “bale-bale”. However, the tendency of fishermen is to design double bale-bale for maximum utilization without considering the sustainability of the fishery resources. This research aims to develop single bale-bale technology for sustainable utilization of flying fish eggs in the waters of the Aru Islands, Indonesia. The vertical single bale-bale is an innovative system designed to enhance the efficiency of capturing flying fish eggs, reduce environmental impact, and support sustainable utilization. The research methodology involves the design and implementation of bale-bale, followed by performance evaluation and environmental impact analysis. The results of the study indicate that the vertical single bale-bale is more effective and sustainable compared to horizontal single bale-bale, mixed, or double configurations. Consequently, this research contributes to improving economic and ecological resilience while promoting environmentally friendly fishing practices.

Seismic Hazard Assessment in Maluku Province Using PSHA

On 10 January 2023, a strong earthquake with a moment magnitude (Mw) of 7.5 occurred in Banda Sea, Maluku Province. This earthquake caused casualties around the epicentre due to the building collapse which was not an earthquake-resistant structure. A high level of seismic vulnerability and non-standard infrastructure often result in large losses when earthquakes occur. Therefore, mapping of earthquake-prone areas needs to be carried out to optimize the mitigation efforts based on Peak Ground Acceleration (PGA) and Spectrum Acceleration (SA) values. In this paper, mitigation efforts are carried out by mapping earthquake-prone areas using Probabilistic Seismic Hazard Analysis (PSHA) which considers the potential of each complex earthquake source in Maluku Province. Input data was obtained from several earthquake catalogues such as Advanced National Seismic System (ANSS), International Seismological Center (ISC), and United States Geological Survey (USGS) which were processed and analyzed using the Matlab, ZMap, and R-CRISIS programs and mapped using the ArcMap program. The results of PSHA show that Maluku Province is a region with varying levels of earthquake vulnerability. The research results show that the distribution hazard value on PGA in Maluku Province reaches 0.02g to 0.48g for a return period of 500 years and 0.04g to 0.79g for a return period of 2,500 years and on SA for periods of 0.20 seconds and 1.00 second reaches 0.04g to 0.89g and 0.01g to 0.22g for a return period of 500 years and 0.07g to 1.48g and 0.02g to 0.35g for a return period of 2,500 years, respectively. The highest level of vulnerability is in the northern region including Seram Island, Way Apu Island and Ambon Island and the lowest level of vulnerability is in the eastern region including Aru Island.
