“…This may be brought on by the severity of the sickness, which depends on the kinds and numbers of fish-infecting bacteria, the environment, and fish immunity. Environmental factors and nutrition appropriate for life can have an impact on the prevalence and intensity of ectoparasites (Aris et al, 2018). Additionally, rain can have an impact on how intense ectoparasites are (Paremme and Salosso, 2018).…”

Freshwater fisheries product tilapia (Oreochromis niloticus) has the potential to be developed and has a very high economic value, particularly in the city of Tarakan. Fish ectoparasites are a problem that frequently occurs and is discovered in aquaculture. This study aimed to determine the type of ectoparasites that infect tilapia in aquaculture ponds in Kampung Satu and Sebengkok. The technique involved collecting tilapia samples from various ponds and then transporting them to the laboratory. A total of 30 samples were taken from the container that was set up on a tray, and they were all put to death by being stabbed in the brain nerves. It was done to identify ectoparasites on the gills, eyes, scales, and fins of the fish. Two forms of ectoparasites, Dactylogyrus sp. and Trichodina sp., which were only present in the gills, were identified in the tilapia. In the moderate infection group, the prevalence rate in Kampung Satu was 86%, and in the very frequent infection category, it was 66% in Sebengkok. In Kampung Satu, the level of ectoparasites was 3,84, which is considered low, and 8,30, which is considered medium, in Sebengkok.

“…) are an important intertidal species in terms of both mangrove ecosystem structure and fishery production, although little is known about their cultivation, diseases and conservation (Furukawa et al 2014). Nevertheless, several studies have been carried out on their parasitic diseases, especially in crabs living in areas polluted with heavy metals (Olgunoğlu and Olgunoğlu 2016;Aris et al 2018;Hasni et al 2020). The pedunculate barnacle Octolasmis is a common crustacean that has a stalk or main stem attached to crustacean (Blomsterberg et al 2004).…”

Abstract. Nur I, Aris EA, Yusnaini Y, Beavis S. 2021. The potential use of Octolasmis spp. parasites in mud crabs Scylla spp. as a bioindicator for mercury pollution. Biodiversitas 22: 3764-3772. Artisanal small-scale gold mining and the use of mercury is widespread across Indonesia, often characterized by relatively short-lived gold rushes. In the late and post-mining phases, mercury stored in mine tailings and river beds was transported down catchment, posing risks to ecosystems and human health over much longer time scales. These risks can be under-rated when mercury concentrations in water, sediments, and aquatic species are low enough to meet relevant guideline thresholds. In this study in Southeast Sulawesi, Indonesia, we have investigated the Costraca barnacle, Octolasmis, as a bioindicator of mercury contamination. The presence of Octolasmis parasites in mud crabs, Scylla spp., and the accumulation of mercury (Hg) in the hosts, parasites, and the ambient environment, were analyzed across both dry and wet seasons. Severe infestation of Octolasmis was assessed using prevalence, abundance, and intensity. Hg concentrations were significantly higher in the Octolasmis parasites than in the host tissues, water and sediments. The mean bioconcentration factor (BCF) of Hg equaled 7938.21 from water to parasites, and 28.91 from the host’s gill tissue to the parasites. The results suggest that Octolasmis spp. can be used effectively as a bioindicator in coastal catchments impacted by mercury contamination, even when concentrations of mercury are low in water and river sediments. The study provides the first report of Octolasmis spp. parasitized to mud crabs as a reliable bioindicator of Hg contamination and pollution.
