“…These data further reinforce the need for a holistic, subpopulation or ESU-based approach to conserving the Banggai cardinalfish and its habitat/microhabitat, as recommended inter alia by (Moore et al, 2017;Ndobe et al, 2013bNdobe et al, , 2018aWiadnyana et al, 2020). Such an approach is vital, to conserve the species within its native (endemic) range, but also the intra-species biodiversity of P. kauderni.…”

“…Sites at which similar surveys were conducted in 2004 (Ndobe et al, 2005) and 2012 (Ndobe, 2013;Ndobe et al, 2013b) are also shown. The T2 monitoring (third annual survey under the NAP-BCFC) was conducted in October 2019 using the standard belt transect method previously used in the T0 NAP-BCFC baseline survey (Ndobe et al, 2018a) and the T1 monitoring (Wiadnyana et al, 2020). This method is very similar to that used in previous surveys (e.g.…”

Abstract. The Banggai cardinalfish Pterapogon kauderni is a species of national and international conservation concern. Established in November 2019, the Banggai marine protected area (MPA) in Central Sulawesi, Indonesia covers most of the endemic range of this ornamental fish. The third repeat survey (T2 monitoring) under the National Action Plan for Banggai Cardinalfish Conservation (NAP-BCFC) was carried out in October 2019 at eight sites in the Bokan Kepulauan region within the MPA. The T2 monitoring used the standard NAP-BCFC belt transect method. Data were collected on P. kauderni abundance (by size class: recruits, juveniles, adults) and microhabitat (sea urchins, sea anemones, hard corals, and others). Data were evaluated with respect to the T0 (2017) survey and T1 (2018) monitoring at the same sites, as well as previous surveys in 2004 (2 sites) and 2012 (4 sites). The data show wide between-site variation in P. kauderni and microhabitat parameters, with one subpopulation at very high risk of extirpation. Trends included declines over time in P. kauderni, sea urchin and sea anemone abundance, with an increase since 2017 in hard coral microhabitat use by adult P. kauderni. We recommend evaluation of other P. kauderni populations in Bokan Kepulauan and specific site or zone-based actions. However, we conclude that the most urgent priority for P. kauderni conservation in Bokan Kepulauan is protection of key microhabitat through a moratorium on sea urchin and sea anemone collection in P. kauderni habitat.

“…Traded globally as a marine ornamental fish since around 1995, exploitation levels of the P. kauderni endemic population were considered excessive by 2000 (Allen, 2000), and by 2007 this species was listed as Endangered in the IUCN (International Union for the Conservation of Nature) Red List (Allen and Donaldson, 2007). While the ornamental fishery has led to or contributed to the depletion of endemic P. kauderni populations (EC-PREP 2005; Kolm and Berglund, 2003;Lunn and Moreau, 2004;Moore et al, 2011Moore et al, , 2021 Depik Jurnal Ilmu-Ilmu Perairan, Pesisir dan Perikanan Volume 10, Number 3, Page 251-259 Serdiati et al ( 2021) Ndobe et al, 2013aNdobe et al, , 2013bNdobe et al, , 2018aNdobe et al, , 2020Vagelli and Erdmann, 2002;Wiadnyana et al, 2020), the marine ornamental trade has also been responsible for introducing P. kauderni outside its native range.…”

“…Twice proposed for listing under CITES Appendix II, the Indonesian Government National Action Plan for Banggai Cardinalfish Conservation (NAP-BCFC) (Rusandi et al, 2016) includes monitoring of both endemic and introduced P. kauderni populations. Annual monitoring in the Banggai Archipelago took place in 2017 (T0), 2018 (T1) and 2019 (T2) (Ndobe et al, 2020;Wiadnyana et al, 2020). While some populations showed stable or increasing trends, at other sites P. kauderni and/or microhabitat continued to decline or remained very low, with some sub-populations considered at risk of extirpation (Ndobe et al, 2020).…”

The Banggai cardinalfish Pterapogon kauderni is the Indonesian national marine ornamental fish mascot, and an object of national and international conservation concern. The endemic population of this species is limited to the Banggai Archipelago in Central Sulawesi, Indonesia and a few nearby islands in North Maluku. In addition, introduced populations have become established, mainly along ornamental fish trade routes. The National Action Plan for Banggai Cardinalfish Conservation (NAP-BCFC) calls for monitoring and management of all P. kauderni populations. A survey of the Luwuk introduced P. kauderni population was carried out in October 2021. Data were collected at three sites with established P. kauderni populations: the ferry harbour, public harbour (Teluk Lalong) and a recreational area on the nearby coast (Kilo 5). P. kauderni were recorded by microhabitat association and size class (recruits, juveniles, adults). Data collected were compared with data from previous surveys where available. With the exception of one group in a sea anemone at Kilo 5, all P. kauderni were associated with Diadema sea urchins (D. setosum at all sites; D. savignyi at Kilo 5). At Kilo 5 P. kauderni the population structure indicates the possible capture of market-sized juveniles. Overall abundance was also lower compared to the polluted but unfished harbours. The proportion of recruits was significantly negatively correlated with the ratio of adult P. kauderni to Diadema urchins. The results will inform regional legislation currently in preparation to support sustainable management of P. kauderni populations, habitat and microhabitat in Central Sulawesi, as well as contributing to NAP-BCFC targets.Keywords:Banggai cardinalfishEndangered speciesDiademaMicrohabitat,MonitoringOrnamental fisheryLocal regulation

The global marine aquarium trade has created new local markets across the planet, including in Indonesia, now the second-largest exporting country of marine aquarium fish in the world. Participating in the global aquarium trade has been touted as a potentially sustainable addition to fisher livelihoods, but scant data exist showing the numbers of fish coming off the reef and how those fish contribute to income. To determine how participants in the trade incorporate aquarium species in their livelihoods, we examine source-level aquarium fish collecting and trading data in the Banggai Archipelago, a region in Central Sulawesi that has become a significant source for popular aquarium, also known as ornamental, fish species. Using a sustainable livelihoods lens, we examine this data to understand how participants in the aquarium trade both contribute to as well as benefit from the trade and consider how their participation relates to emerging Blue Justice principles. From one year of buying and selling data at the fisher, intermediary buyer, and regional trader levels, we show that catching and selling fish for the aquarium trade represents an average of nearly 20% of their gross annual income and provides added diversity and flexibility to fisher and trader livelihoods in the region, especially during seasons of rough weather. We suggest that managers of an impending marine protected area in the region would do well to consider how to sustain these livelihood benefits.
