Abstract

In the marine reallm restricted range endemic species are rare. One such species which has attracted much attention is the Banggai cardinalfish (Pterapogon kauderni, Koumans 1933), often referred to as BCF, a coral reef associated fish endemic to shallow waters (0-5m) around the Banggai Archipelago, Indonesia. As in most of the Coral Triangle, these coastal waters are under heavy pressure from a variety of anthropogenic impacts. Traded as a marine ornamental, the IUCN Red-List places P. kauderni in the Endangered category with overexploitation and habitat degradation as the major threats. After the (unsuccessful) proposal for listing under CITES Appendix II in 2007, a national action plan (BCFAP) was developed and BCF conservation included in the Indonesian Coral Triangle Initiative National Plan of Action (CTI-NPOA). Monitoring is widely accepted as an integral part of effective management. The BCF-AP calls for biophysical and socio-economic monitoring of the Banggai cardinalfish trade, population and habitat to support the development of a sustainable ornamental fishery and ensure the conservation of the Banggai cardinalfish. Monitoring systems developed, activities undertaken and data produced are reviewed. Trends revealed by the data include a marked increase in compliance with current fish quarantine regulations, and other improvements in P. kauderni use patterns. Together with recent research, the data also reveal the need for an especial focus on key micro-habitat, Diadema urchins and sea anemones, which are under pressure from increasingly intensive harvesting. Monitoring systems are evaluated and suggestions for improving the usefulness and scope of monitoring activities are presented.

Abstract

The Banggai cardinalfish (Pterapohon kauderni, Koumans 1933),often refered to as BCF, is a restricted range coral reef associated fish endemic to shallow waters (0-5m) arround the Banggai Archipelago, Indonesia. Listed as Endangered un the IUCN Red-List. In 2007 a national BCF Action Plan was developed , and a Distrct MPA was established by decree of the Banggai  Kepulauan District Head, consisting of a network of 10 islands. For 2 of these P. Kauderni conservation in the main management target. We reviewed available phylogenic, genetic and biogeographical data, and examined the MPA network from the viepoint of P. Kauderni genetic diversity conservation. With no pelagic phase and high fidelity, the Banggai cardinalfish population exhibits a level of genetic structure unusual in a marine fish. Several genetically distinct sub populations have been identified. It was concluded that management units should be based  on genetically detrmined sub-populations (stocks). Critical knowledge gaps and several research pririties were identified. In particular , we conclude that a researh programme is necesary for the identification and characterisation of these genetically determined units from biological (including genetic), ecological (e.g. habitat/micro-habitat) and socio-economic (including fishing ground) aspects. We propose to provide management support through the use of the spatial analysis tool MARXAN combined with a GIS database to produce science-based zoning options with management units/targets based on genetic population structure.

Abstract

The endangered Banggai cardinalfish Pterapogon kauderni, endemic to the Banggai Archipelago in Central Sulawesi, Indonesia, is a national and global priority conservation species. To support stock recovery based on in-situ breeding, using the symbiosis between the Banggai cardinalfish and its microhabitat (especially urchins of Genus Diadema), specific research objectives were: (i) identify the Diadema species associated with Banggai cardinalfish in the wild; (ii) investigate Banggai cardinalfish preference between these Diadema species. Belt transect data (5 sites) found wild Banggai cardinalfish of all size classes associated with Diadema setosum and Diadema savignyi. Preference trials were conducted in a controlled environment (concrete tanks) with three replicates. Nine sub-adult Banggai cardinalfish (35-42 mm SL), 12 D. setosum and 12 D. savignyi were placed in each tank. Banggai cardinalfish association (D. savignyi, D. setosum, none) was recorded hourly (06:00-18:00) for three days and results analysed in RStudio-1.0.143. Banggai cardinalfish did not show significant preference for either D. savignyi or D. setosum. These results indicate that D. savignyi and D. setosum can be used impartially in further research on in-situ breeding to facilitate recovery of Banggai cardinalfish stocks. However stock recovery measures should consider genetic connectivity and the natural balance between the two urchin species.

Abstract

Ikan gabus Channa striata merupakan ikan air tawar yang secara tradisonal ditangkap dan dikonsumsi oleh masyarakat asli Sulawesi Tengah, namun saat ini populasinya di alam cenderung mengalami penurunan. Eksploitasi ikan gabus yang terus meningkat disebabkan oleh kesukaan konsumen terhadap dagingnya yang lezat dan gizinya yang tinggi serta kandungan albuminnya yang tinggi mengakibatkan permintaan ikan gabus sebagai makanan kesehatan dan bahan baku industri farmasi semakin meningkat. Salah satu upaya yang dapat dilakukan untuk mencegah penurunan populasi ikan gabus di alam adalah dengan melakukan pembesaran benih ikan gabus, namun hal ini terkendala pada ketersediaan pakan, khususnya pada tahap awal pembesaran yang merupakan fase kritis. Tujuan penelitian ini adalah untuk mengetahui pengaruh feeding rate terhadap pertumbuhan dan sintasan benih ikan gabus yang diberi pakan cacing darah beku. Penelitian ini menggunakan rancangan acak lengkap dengan lima perlakuan dan empat ulangan. Benih ikan gabus (bobot tubuh 0.17±0.10 dan panjang total 2.5±0.5 cm) diberi pakan cacing darah (tiga kali sehari) dengan lima rasio pakan/bobot tubuh yaitu: P1=6,5%, P2=8,0%, C=9.5%, D=11,0% and E=12,5%. Benih dipelihara dalam wadah terkontrol berisi tujuh liter air dengan kepadatan penebaran sebesar satu ekor/liter. Parameter yang diukur adalah pertumbuhan mutlak (bobot tubuh dan panjang total) serta sintasan. Perlakuan pakan 12,5% /bobot tubuh ikan memberi hasil terbaik dengan pertumbuhan mutlak bobot tubuh benih ikan gabus yang secara nyata lebih tinggi jika dibandingkan dengan keempat perlakuan lainnya.

Abstract

Indonesia is widely recognised as the centre of freshwater eel diversity. The recruitment of tropical glass eels generally occurs in multi-species schools. Identification of species present and recruitment patterns at regional and watershed scales are necessary to conserve eel biodiversity and manage eel populations sustainably. Data on eel taxonomy, phylogeography and biogeography are still limited in many areas. Research over the period 2009–2012 aimed to: 1) determine the species composition of glass eels recruiting to Palu River, flowing into Palu Bay on the Central Sulawesi Makassar Straits coastline; and 2) to develop a suitable method for live glass eel identification. Sampling was carried out over 29 months: January–April 2009, May–November 2010, April–December 2011 and March–November 2012. Two species were positively identified using the ano-dorsal vertebrae count (ADV) method, Anguilla marmorata and A.bicolor pacifica. The presence of other species (possibly one to three species) is important from conservation and biodiversity aspects. Temporal variations in species composition, with no apparent consistent seasonal or annual pattern raise questions requiring a multi-disciplinary approach.

Abstract

Sea urchins have long been an important component of gleaning invertebrate fisheries and are valued for their highly nutritious gonads. Sea urchin fisheries are often unreported and unregulated, despite increasing indications of overexploitation. Data on the post-harvest utilization of sea urchins are limited, particularly in the Indo-Pacific region. This study at 12 sites across four regions in Indonesia (Sulawesi, Moluccas, Nusa Tenggara, Papua) aimed to provide an overview of sea urchin utilization in eastern Indonesia. Data were collected from July to September 2020 using a questionnaire with a snowballing sampling method. There were 187 respondents (62.6% male and 37.4% female) ranged in age from 3-76 years old, and most had been collecting sea urchins for more than five years. Respondents mostly collected the sea urchins from coral reef or seagrass habitats. Four genera (Tripneustes, Diadema, Echinometra and Echinothrix) were identified. Mean catch ranged from 32 (Makassar) to 169 (Maluku Tengah) individual sea urchin per collection. Most respondents knew local names for sea urchins, especially those they collected. Almost 70% respondents used their catch mainly for home consumption, and only 4.8% respondents mainly selling their catch. Most urchins sold were whole or crudely de-spined, typically fetching IDR 500-1000 each. Additional post-harvest processing before sale included removing the gonads from the test and/or cooking, with a unit price of IDR 5,000-25,000/product. Commonly consumed raw, urchins were sometimes cooked (mostly barbecued). These data indicate a need for efforts towards socio-ecologically appropriate sea urchin conservation and fisheries management to address the widespread indications of increasing exploitation levels and declining sea urchin populations.

Abstract

Graphical Abstract   Highlight Research  Integrated DNA barcoding and morphological variations can improve the identification of grouper species. DNA barcoding confirms the morphological identification of Plectropomus (98-100% similar). High intraspecies genetic diversity revealed within Plectropomus in Makassar Strait. Potential cryptic species identified within Plectropomus based on genetic analysis.     Abstract  The high economic value of groupers has made them a popular choice in both local and international markets. However, identifying grouper species is also challenging due to complex morphological variations especially in the juvenile phase. An integrative approach combining DNA barcoding and morphometric analysis was applied to improve species identification accuracy and provide additional information on grouper stocks. This research aims to gain a deeper understanding of the morphological and genetic diversity of groupers caught in the juvenile phase from the Makassar Strait. Samples of the genus Plectropomus (n=6) collected from a fish landing site in Pangkajene Kepulauan Regency were identified based on morphology and using molecular methods (DNA barcoding). Phylogenetic and haplotype network analyses were performed. For all specimens the morphometric-meristic and molecular analyses were consistent (98-100% similarity) to known P. leopardus and P. oligacanthus accessions from GenBank. However, phylogenetic analysis: P. leopardus clustered into two distinct lower-level clades, and notably, two P. areolatus (Taiwan) resolved within the P. leopardus clade, while two P. laevis (Philippines) the resolved within the P. oligacanthus clade. Haplotype network showed high intraspecific genetic diversity, with P. leopardus forming four distinct haplotype groups and P. oligacanthus forming two groups. These findings collectively indicate that misidentification may be common and highlight the urgent need for further investigation into geographic barriers to gene flow and the potential existence of cryptic species or subspecies within Plectropomus. This study is expected to provide critical support for sustainable fisheries management and the conservation of marine biodiversity in the Makassar Strait.
