Fisheries Enhancement

Fisheries enhancement initiatives including marine stocking and artificial reef deployments are becoming increasingly common in many parts of the world. Combining the two by releasing hatchery reared fish onto artificial reefs is used in sea-ranching operations but is an approach rarely adopted for recreational fisheries. Yellowtail kingfish (Seriola lalandi) form a valuable recreational fishery in Australia and in 2018 a pilot stocking program was initiated to enhance this fishery. Fish were released onto estuarine artificial reefs in Botany Bay to evaluate if estuarine artificial reefs are suitable release habitat for juvenile yellowtail kingfish and to monitor their dispersal patterns using acoustic telemetry and a tag-recapture program. Both approaches showed similar patterns, indicating juvenile yellowtail kingfish rapidly dispersed from the release location and can travel at least 60 km during their first weeks in the wild. Twenty percent of the acoustically tagged fish entered nearby estuaries to the north and south and tagged fish were also recaptured in these estuaries, indicating that the estuaries provide habitat for juveniles. There was little interaction between stocked fish and two large coastal artificial reefs positioned near Botany Bay. Stocked yellowtail kingfish will likely disperse rapidly from release locations which is consistent with their pelagic life history. While this may present challenges to fisheries managers, increasing release numbers to maintain stocking densities over a broader area may provide a solution. Future releases of fish on coastal natural and artificial reefs are an important next step in refining stocking practices for this species and will help further identify key juvenile habitats.

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.

Coral Fish

Coral reefs in Malalayang coastal waters has degraded due to impact of restoration and pollution, especially domestic disposals. It makes the fishermen communities who depend upon the coral reef fisheries difficult to fish in the coastal waters. One of the solutions for coral restoration is to develop artificial reefs. The objective of the study is to know the ecological condition of the fish communities in two types of artificial reefs, biorock and paralon pipe. Data sampling was done every week for one month in the morning at 09.00 O’clock am and afternoon at 14.00 pm, using stationary visual census method. The data covered species and number of coral fishes around the artificial reefs. Data analyses focused on the diversity and the richness individu. Results showed that the fish communities in both artificial reefs that the fish occurrence in the biorock were relatively higher than those in the paralon pipe, this is related to habitat conditions in biorock providing a greater opportunity for the presence of fish there. There were 13 to 15 fish genera found in both artificial reefs. The highest number was recorded in the morning. The diversity of fish species is low, but the abundance of fish is classifiedas moderate criteria.Keywords: artificial reef, coral fish, Malalayang Manado, BiorockAbstrakTerumbu karang di perairan pantai Malalayang sudah mengalami degradasi, karena dampak kegiatan reklamasi dan polusi terutama sampah. Hal ini menyebabkan masyarakat nelayan yang hidupnya bergantung pada perikanan terumbu karang semakin sulit menangkap ikan di perairan pesisir. Salah satu solusi yang ditawarkan untuk merestorasi sumberdaya alam yang rusak adalah terumbu buatan. Tujuan penelitian ini adalah mengetahui kondisi ekologi komunitas ikan pada dua tipe terumbu buatan, yakni biorock dan pipa paralon. Pengambilan data dilaksanakan dua kali dalam sehari yaitu pagi hari (pukul 09.00 Wita) dan siang hari (14.00 Wita) selama sebulan, dengan menggunakan metode stationery visual sensus. Data komunitas ikan yang dianalisa adalah keragaman dan kekayaan jenis. Hasil yang diperoleh adalah Keberadaan ikan di terumbu buatan biorock relatif lebih banyak dari pada di terumbu buatan pipa paralon. Ada 13 sampai 15 jenis ikan yang ditemukan di terumbu buatan biorock dan pipa paralon. Jumlah yang terbanyak dijumpai pada pengamatan di pagi hari. Nilai keragaman jenis ikan tergolong rendah, namun memiliki kelimpahan ikan yang tergolong sedang sampai tinggi.Kata kunci: Terumbu buatan, ikan karang, Malalayang Manado, Biorock.
