Abstract

Tor soro is a freshwater fish species with high economic and ecological value. However, adequate production does not support the increasing demand for its fry, primarily due to its slow growth performance. One potential approach to overcome this limitation is feed enrichment with B-complex vitamins. This study aimed to evaluate the optimization of growth performance in T. soro fry through dietary supplementation of B-complex vitamins. The experiment was conducted using a Completely Randomized Design (CRD) with two treatments and three replicates: VT0 (0 g kg⁻¹) and VT1 (2 g kg⁻¹). Fish were reared for 60 days in aquaria (60 × 30 × 35 cm³). The results demonstrated that VT1 significantly improved (p < 0.05) both growth and feed performance. Absolute length and weight gain reached 2.85 ± 0.10 cm and 1.29 ± 0.03 g, while specific and daily growth rates were 3.96 ± 0.03% and 2.16 ± 0.05 g day⁻¹, respectively. Moreover, supplementation of B-complex vitamins reduced feed utilization, as indicated by feed conversion ratio (FCR) and feed efficiency values of 2.75 ± 0.06 and 36.43 ± 0.81%, respectively. These findings suggest that feed enrichment with B-complex vitamins can effectively enhance the growth performance of T. soro fry.

Abstract

Rumput laut Kappaphycus alvarezii merupakan salah satu komoditas perikanan yang dikembangkan di Kota Tarakan khususnya di Perairan Pantai Amal Kota Tarakan sejak tahun 2009 dengan produksi yang fluktuatif. Tujuan penelitian ini adalah untuk menganalisis kelayakan finansial budidaya rumput laut berdasarkan faktor internal dan eksternal serta menyusun strategi yang tepat untuk peningkatan produksi rumput laut di Kota Tarakan. Teknik pengambilan sampel secara purposive sampling dengan pendekatan kualitatif menggunakan alat bantu kuesioner. Hasil analisis SWOT (strengths, weaknesses, opportunities, and threats) dan QSP (quantitative strategic planning) menunjukkan bahwa terdapat lima kekuatan dan lima kelemahan internal dengan nilai IFE (internal factor evaluation) 2,57, serta empat ancaman dan lima peluang eksternal dengan nilai EFE (external factor evaluation) 2,86. Berdasarkan matriks IE (internal-eksternal) usaha berada dalam fase pertumbuhan (sel V), sehingga strategi yang tepat untuk mengembangkan usaha budidaya rumput laut K. alvarezii menggunakan metode longline di Kota Tarakan melalui pemberdayaan anggota dan kelompok guna peningkatkan usaha (dengan skor 5,83), memperluas lahan budidaya (skor 5,65), dan peningkatan keterampilan teknis budidaya untuk peningkatan kualitas dan kuantitas produk (skor 5,52).

Abstract. Hastuti YP, Rusmana I, Nirmala K, Affandi R, Tridesianti S. 2019. Identification and characterization of nitrifying bacteria in mud crab (Scylla serrata) recirculation aquaculture system by 16S rRNA sequencing. Biodiversitas 20: 1339-1343. Recirculation is one of the systems used for increasing aquaculture production, for example, is mud crab Scylla serrata culture. Aquaculture activities will produce organic nitrogen waste and can be affected to inorganic condition (nitrification bacteria). Nitrifying bacteria are capable of changing aerobically from NH4+ to NO2-(nitrite) and from NO2-to NO3-(nitrate). This current work aimed to identify and characterize nitrifying bacteria in mud crab (S. serrata) culture with a recirculated system. Nitrifying bacteria were isolated using serial dilution (10-1 until 10-5) of open filter FB water sample previously cultured in a specific medium. Bacterial identification was performed using a procedure of PrestoTM Mini gDNA Kit (Geneid) for DNA extraction and Polymerase Chain Reaction (PCR) primer 63F and 1387R for 16S rRNA gene amplification. Molecular identification using 16S rRNA sequences, the nitrifying bacteria isolated from mud crab recirculation aquaculture system were 99% identified as a group Pantoea calida, Pseudomonas stutzerii dan Halomonas sp. Morphological characterization of the colony morphology showed that a mucoid appearance and appeared cream in color and large size. Furthermore, their cells were recognized as basil and Gram-negative.
