Abstract

This study was carried out in a monotonous swamp in Hulu Sungai Utara Regency, South Kalimantan Province. The purpose was to find out the plankton fertility in supporting fish productivity in the monotonous swamp to build a dynamic waterbody with all of its supporting aspects. The analyses were performed on plankton diversity, water quality parameters and fish production levels from 2009 to 2013. The results of Shannon-Wiener diversity index analysis for plankton in the swamp approximately exceeded the value (>2), indicating that the water condition was still good and fertile. The water quality parameters in the swamp were specific; blackish brown in color, acid, and having low level of oxygen with high ammonia concentration. The decreasing trends of fish productivity in the swamp were resulted from unselective fish catching, environmental pollutions and land-use changes converting the swamp areas into plantations and housing. Therefore, it is necessary to develop conservation areas to keep the primary productivity of the waterbody in high level, which would affect the increase in the productivity of swamp fish.Keywords: plankton, water quality, fish productivity.

Abstract

Aquaculture in Riam Kanan river receives watersupply from rivers and Riam Kanan reservoir from upstream to downstream and practices different irrigation and fertilization systems. This study was aimed to compare the planktoncommunity structure, to find out the physicalchemical parameters associated with the abundance of plankton and the fertility of the fish-farming ponds. The research was conducted at Mandiangin Freshwater Aquaculture Center (Balai Budidaya Air Tawar – BBAT), Karang Intan (Balai Benih dan Induk Ikan Air Tawar – BB-IAT) and Cindai Alus Minapolitan area by using the observationmethod. Water samples were taken by composite of 6 replicates at 12 stations. The parameters measured were temperature, visibility, pH, iron, free ammonia, nitrate, phosphate, DO, BOD and plankton analysis. Data were tested statistically with cluster, Pearson correlation and regression. The result shows that there are differences in plankton community structure in the fish ponds, shown by 5 cluster groups. The abundance of phytoplankton has a significant correlation with pH, temperature, DO, and free ammonia. The abundance of zooplankton also has a significant correlation with pH, DO, BOD, and free ammonia. The seed pond at BBAT Mandiangin is eutrophically dominated byBacillarophyta and Amoboezoa, while in BB-IAT Karang Intan and Cindai Alus are dominated by Cyanophyta and Rotifera. The inlet channel of BB-IAT Karang Intan and the broodstock pond belong to mesotrophic category, predominanceby Cyanophyta, Chlorophyta and Rotifer. BBIAT Karang Intan outlet ponds, BBAT Mandiangin inlet channel and Cindai Alus inlet pond are included in the oligotrophic category, predominance by Cyanophyta and Chlorophyta. Plankton community structure of the fishfarming pond varies even with the same ecological conditions.

Abstract

Ansyari F, Slamat S. 2020. Comparison of the performance of climbing perch (Anabas testudineus Bloch) filial 2 fry and natural fry treated in acidic swamp waters, Jejangkit Village, South Kalimantan. Jurnal Lahan Suboptimal: Journal of Suboptimal Lands 9(1): 23-30.The aim of the study was to compare the performance (survival rate, growth and feed conversion) of climbing perch fish fry Filial 2 (F2) which has superior characteristics with natural fry that are culture in sour swamp waters. The study was carried out in swamp waters, Jejangkit Village, Barito Kuala Regency, South Kalimantan for 6 months (January to June 2019). This study compared fish performances generated from F2 fry of nature. Fishes were cultured in net (4 m x 2 m x 1 m) with the same stocking density of 100 fishes/m2 . The results showed that the survival rate of natural fry was 86.6% higher than that of F2 75.3%, but the relative growth of natural fry was 2,325% lower than  F2 3,060% and feed conversion natural fry was 3.03 less efficient than F2 fry 2.62. It was concluded that the performance of F2 fry was better than natural fry, when maintained in acidic swamp waters.

Abstract

Penelitian ini dilakukan dengan menggunakan sample ikan betok (Anabas testudineus Bloch 1972) yang berasal dari perairan rawa Kalimantan Selatan, dengan tujuan untuk mendeskripsikan keragaman  genetik dan aspek konservasinya dengan metode amplifikasi mtDNA. Proses amplifikasi mtDNA ikan betok terjadi di daerah D Loop.  Hasil analisis mt-DNA D Loop ikan betok menunjukkan bahwa, analisis keseimbangan populasi Hardy-Weinberg  berkisar antara 0,02 - 0,09, sedangkan haplotipe tertinggi terdapat pada rawa monoton (0,9384), kemudian tadah hujan (0,7111) dan pasang surut (0,6).  Heterozigositas ditemukan unik pada populasi rawa monoton (BAAAA) dan rawa pasang surut (BAACA) dan umum di temukan di ketiga ekosistem rawa (AAABA).  Ikan betok di bagi menjadi dua stok populasi yaitu populasi rawa monoton dan pasang surut serta stok tadah hujan.  Konsep utama dalam konservasi genetik adalah fitness population dimana populasi dipertahankan minimal 500 ekor/kawasan. Untuk meningkatkan keragaman genetik ikan betok, dilakukan dengan cara introduksi individu-individu baru yang memiliki keragaman genetik yang lebih tinggi kedalam populasi lokal, restocking dan membuat kawasan suaka yang dilindungi oleh Dinas Perikanan setempat bersama-sama dengan masyarakat di sekitar perairan rawa tersebut. The research was conducted using climbing perch samples originated from the swampy waters of the southern Borneo, and the objektive of this study to investigate the genetic diversity and the conservation aspect using mtDNA amplification method.  mtDNA amplification process occurs in the D Loop region.  The results of the analysis of D-Loop mtDNA of climbing perch showed that, the analysis of Hardy-Weinberg equilibrium population ranged from 0.02 to 0.09, while the highest haplotypes found in swamp bogs (monotonic) (0.9384) then rainfed (0.7111) and tides (0.6). Heterozygosity was found uniquely in the swamp monotonic population (BAAAA) and marsh tides (BAACA) and common in all three ecosystems found in the swampy area (AAABA) . Climbing perch stock divided into two populations monotone and tidal swamp population and rainfed stock.  The main concept of genetic conservation is the fitness population where the population is maintained at least 500 tail/region.  To increase the genetic diversity of climbing perch, can be done by the introduction of new individuals wich has a higher genetic diversity into the local population, restocking and create reserves of protected areas by the Local Fisheries Authority together with the community around the swampy waters.

Abstract

Snakehead fish is an important economic fish with increasing economic value because of its distinctive and delicious taste and high protein and albumin content. The development of snakehead fish farming does not develop rapidly, where one of the contributing factors is the continuous availability of seeds. This community service activity was carried out from September to December 2019 with the target audience of the “Mufakat” Fish Cultivator Group, Mahang Baru Village, South Labuan Amas District, Hulu Sungai Tengah Regency, South Kalimantan Province. The implementation method is through lectures, FGDs, short training, demonstrations, and mentoring. The facilities for hatchery of snakehead fish are in the form of 6 (six) tarpaulin ponds measuring 2.5 m x 1.5 m x 1 m. The results of hatchery activities obtained an average egg hatchability of 84.1% and the survival rate from larvae to 2-month-old seed reached 43.81%. Profits obtained during one production cycle (3 months) reached IDR 10,237,500, -, B/C ratio = 1.83 and return on capital = 1.22 period. The results of the average similarity test to the target audience were found to be successful in increasing knowledge and skills of snakehead fish hatchery after the activity.

Abstract

Tujuan penelitian menemukan pola hybridisasi yang tepat dalam memproduksi benih ikan papuyu yang memiliki karakter unggul, sehingga dapat menunjang peningkatan produktivitas ikan kearah yang lebih baik. Penelitian hybridisasi ini dilaksanakan di UMKM Rawa Sejahtera Amuntai dan analisis Laboratorium di FPK – ULM pada bulan Januari – Juli 2016. Metode penelitian dengan rancangan acak lengkap (RAL) (tiga perlakuan dan sembilan ulangan) yaitu menghybrid induk ikan papuyu dari rawa tadah hujan, pasang surut dan monoton. Hasil aplikasi penelitian diperoleh data hybridisasi yang meliputi fekunditas, indeks kematangan gonad, fertilisasi, daya tetas, mortalitas, pertumbuhan panjang relatif, pertumbuhan berat relatif, food coversion ratio (FCR), kesehatan ikan, persentasi jantan dan betina, menggambarkan hybridisasi induk ikan dari rawa monoton dengan pasang surut lebih unggul dibandingkan hybridisasi induk ikan dari rawa tadah hujan dengan monoton serta pasang surut dengan tadah hujan. Hasil pengkerakteran benih ikan hybridisasi rawa pasang surut dengan rawa monoton yang paling menonjol adalah persentasi kelahiran betina >80%, FCR dan pertubuhan lebih tinggi, yang terbukti dengan hasil statistik yang berbeda nyata. Dalam proses pengembangan budidaya ikan papuyu, faktor utama keberhasilannya adalah penggunaan benih berkelamin betina, dimana pertumbuhannya lebih cepat 270% dibandingkan benih jantan, sehingga sangat tepat untuk dijadikan bibit dalam proses pembesaran dalam kolam.
