Abstract. Wijayanti DP, Nadia M, Indrayanti E, Haryanti D, Bachtiar M. 2021. Short communication: Algal genotypes in White Syndrome infected coral Acropora muricata from the Karimunjawa Islands, Indonesia. Biodiversitas 23: 415-423. The physiological equilibrium of the coral holobiont may help the corals to survive under various environmental threats. The symbiont genotype is thought to play an important role in the host's susceptibility to thermal stress and coral disease incidence. We identified the Symbiodiniaceae diversity of coral Acropora muricata infected by White Syndrome (WS). Samples were collected from Cemara Kecil Island and Barakuda Beach, Kemujan Island, Karimunjawa Islands. We applied DNA barcoding of 28S nuclear ribosomal RNA gene of the healthy colonies, healthy tissue, and lesions of diseased colonies to perform their symbiont type identification. There were two different symbiont types observed from the phylogenetic analysis, which formed two clades. A clade consisting all Cemara Kecil Island samples while the other with all Barakuda Beach samples except for one. All samples harbored symbiont types from the genus Cladocopium. The members of the genus were reported to have various physiological properties which may support the host resilience when facing the disease. A robust study is needed to reveal the influence of symbiont genotypes on the occurrence of coral disease and the susceptibility of the coral host.

Abstract. Rudianto EA, Wijayanti DP, Haryanti D, Indrayanti E. 2024. Short Communication: Helminth fauna of Lutjanidae from Kedonganan, Bali. Biodiversitas 25: 4986-4993. The biodiversity of parasites in demersal reef fishes is immense but remains poorly understood and often overlooked. This is also hindered by the lack of survey of parasite communities in reef fishes, especially in Indonesia. Therefore, we surveyed endoparasites of reef-associated and demersal lutjanids in the Kedonganan fish market, Bali. A total of 25 individuals of six lutjanid species: Lutjanus erythropterus, Lutjanus russellii, Lutjanus sebae, Lutjanus timoriensis, Lutjanus vitta, and Pristipomoides multidens, were collected from the fish market. The parasites were collected using a modification of the gut wash method. Two individuals of Philometridae were recovered from L. vitta. Other recovered helminth fauna were Acanthocephala, Nematoda, and Digenea, mainly belonging to Siphoderina spp. and Hamacreadium sp. We also reported for the first time, endoparasites of L. erythropterus and P. multidens in Indonesian waters. This study highlighted the importance ichthyo-parasitological survey as a part of the biodiversity survey. More surveys and reports on endoparasites in demersal reef fishes in Indonesia are needed, especially on their biology, ecology, diversity, and impact on human health, considering that most of these demersal fishes are consumed by local people.
