Abstract. Nuryanto A, Bhagawati D, Kusbiyanto. 2020. Evaluation of conservation and trade status of marine ornamental fish harvested from Pangandaran Coastal Waters, West Java, Indonesia. Biodiversitas 21: 512-520. Pangandaran coastal waters are among the main supply areas of marine ornamental fish in Indonesia. However, no scientific data are available on the conservation and trade status of marine ornamental fish harvested in this region. This study aimed to evaluate the diversity, conservation, and trade status of marine ornamental fish species harvested from Pangandaran coastal waters. Fish were collected during surveys conducted in March, April, July, and September 2019. Species were identified by referring to the available guidance books. The conservation status was analyzed according to the IUCN database, whereas the trade status was evaluated based on the CITES database. A total of 107 marine ornamental fish species from 32 families and eight orders was obtained. The two out of these 107 species had an unresolved conservation status, whereas 24 species were listed as Not Evaluated, 80 species were listed as Least Concern, and one species was listed as Vulnerable by IUCN. Two species had an unknown trade status, whereas 104 species were listed as Not Evaluated and one species was listed in Appendix II of CITES. Our data prove that Pangandaran coastal waters have a high potential for supplying marine ornamental fish, with most of the species listed as having a Not Evaluated or Least Concern status. Most of the species identified were also categorized as having a Not Evaluated trade status.

Several studies had reported marine ornamental fish are exported from Indonesia to the United States of America. However, there is no study about marine ornamental fish that has been done with particular reference to specific localities across Indonesia, mainly from the southern coast of West Java. This study aims to know species diversity and conservation status of marine ornamental fish traded in Pelabuhan Ratu, Ujung Genteng, and Taman Manalusu. Fish samples were bought from the first collector in each sampling locality. Fish species were identified morphologically according to the previous publication. A total of 93 nominal species, 22 families, and six marine ornamental fish orders were traded. The highest number of species belonged to Pomacentridae and followed by Achanturidae, Labridae, and Chaetodontidae. The remaining families consisted of one up to six species. Perciformes was the dominant order with 19 families. Most of the species are listed as Least Concern conservation status, and one species listed as vulnerable, namely Hippocampus kuda (sea horse). Our results proved that many marine ornamental fish were on the southern coast of West Java and mostly listed as Least Concern species.

There was a degraded ecosystem and an affected decreasing nekton and microbenthos at River Pelus. So far, no publication of macrobenthos is available. The research purpose was to map species richness and longitudinal distribution of macrobenthos. The survey method was taken with stratified random sampling in eight stations and five replicates from May to July 2018. The result showed ten species of macrobenthos. All species belonged to class Malacostraca (four species) and Gastropoda (six species). Of the four species collected in all replicates, Macrobrachium oenone categorized as an indicator species that only lived in Station II because there were a boulder substrate and good water quality. In the same class, M. pilimanus, Parathelpusa bogoriensis, and P. convexa were in all stations except station V because there was a sand substrate and poor water quality. In station V, there were only two species of gastropod, Melanoides riquerti and Pomacea canaliculata that could live. In general, there were a cosmopolitan species that could live in all substrates and water quality such asM. riquerti. For a longitudinal distribution map, there was a unique tendency of decreasing species richness numbers due to the river weir.

Cilacap has a high potential for marine fisheries. However, no scientific data is available on the potential of marine ornamental fish from that area. Here we reported the preliminary study of the potential of marine ornamental fish from the southern coast of Cilacap with particular emphasis on species richness. A survey method with incidental sampling was conducted. Fish samples bought from the fish collector in Sentolo Kawat Village, District of South Cilacap, at Cilacap City. The fish samples were collected in April, May, and July 2019. Taxonomic identification of the fish samples was referring to the available reference and validated to the data in FishBase. Identification based on color pattern and meristic characters by considering geographic ranges of the specimen placed the samples into 28 species, 12 families, and four orders. Chaetodontidae was the most abundant family with nine species. Most fish belonged to Perciformes. We obtained a lower number of species compared to the previous study for the south coast of Java. It could be due to the narrower sampling areas and limited sampling periods. Nevertheless, our result provides information about the potential of marine ornamental fish in Cilacap as among promising income sources for the Cilacap Regency. However, government intervention is necessary for the sustainable use of ornamental fish in the area.
