Abstract. Isroni W, Samara SH, Santanumurti MB. 2019. Short Communication: Application of artificial reefs for fisheries enhancement in Probolinggo, Indonesia. Biodiversitas 20: 2273-2278. Overfishing is one of the biggest challenges in the fisheries sector in Probolinggo, Indonesia. The fish apartment (artificial reefs) was one of the solutions to increase the fish resource since it serves as the habitat for fish to live, spawn, and search for food. In this study, the fish apartment was installed in Probolinggo (Karang Katon and Dringu Beach) from 2017 to 2018. This study showed that five fish species (Caesio cuning, Acanthurus achilles, Acanthurus albipectoralis, Sphyraena jello, and Apagon novemfasciatus) were found in Karang Katon while four species (Chaetodon octofasciatus, Chromobotia macracanthus, Nemipterus japonicas, and Lates calcarifer) lived in Dringu Beach. From a total of 333 fishes, A. achilles was the species with the highest composition level of 51.65% (172) in Karang Katon station. In Dringu Beach station, C. octofasciatus had the highest fish species composition level of 46% (183) from a total of 402 fishes. The diversity index and dominance index in Karang Katon station were low at-1.280 and 0.343, respectively. The diversity index and dominance index in Dringu Beach station were also low at -1.115 and 0.3503. A. achilles had the highest density of 34.4 ind/m3 in Karang Katon station while C. octofasciatus had the highest species density of 36.6 ind/m3 in Dringu Beach Station. From this study, it could be concluded that artificial reefs application enhanced the fisheries in Probolinggo, Indonesia, and help its sustainability.

Sea urchins is marine organism from Phylum Echinoderms which have high economic and ecological value. Therefore, we need data on the current condition of sea urchins, especially those in the Spermonde Islands. Through this research, it is hoped that the community structure and distribution of sea urchins in Kodingareng Lompo Island, Spermonde Islands can be known. The sampling method used was quadrant transects measuring 5x5 meters on 4 plots in the seagrass area on Kodingareng Lompo Island. The data analysis used was species composition, density, relative density, diversity index, and uniformity index. The results obtained show that there are three species of sea urchins, namely Diadema setosum, Mespilia globulus, and Tripneustes gratilla, basen on morphology identification. Diadema setosum is species with the highest species composition value, namely 92%. The density value (0.017 individuals / m2) and the diversity of sea urchins (H '<1) in the seagrass beds at Kodingareng Island are classified as low. It is hoped that the data obtained from this research can become a reference for the management of biological resources in the Spermonde Islands in the future. Landak laut merupakan salah satu kelas dari Filum Echinodermata yang memiliki nilai ekonomis dan ekologis yang cukup tinggi.

Biodiversity of fishes in musi estuary, South Sumatra, Indonesia.  Jurnal Lahan Suboptimal : Journal of Suboptimal Lands 9(2): 192-198.The high activity in the Musi estuary will have an impact on fishes diversity. This research aimed to analyse the biodiversity of fishes in the Musi estuary in South Sumatra. An experimental fishing method was used for data collection by fishing ground following the local fishermen habit using gillnet millennium. The abundance of fish species found were 21 species and 16 families. The main catch was Hemibagrus nemurus with a high relative abundance (RA) of 35.4% but the high availability frequency of 100% is Eleutheronema tetradactylum. The average value of the moderate diversity index (H'= 1.47), the moderate evenness index (J'= 0.48) and the low dominance index (D= 0.32). This condition shows that the community structure of the species captured by the gill net is in a fairly stable condition with the number of species that are spread fairly evenly and no species dominate each other.
