Judul: Perbedaan Karakteristik Semen Ikan Nilem (Osteochilus vittatus) pada Ukuran Tubuh yang Berbeda
Abstrak: Osteochilus vittatus well known as bonylip barb is an important economic freshwater fish rarely to find and considered that the quality of caviar has been degraded. Meanwhile the most important thing of cultivation process is the availability of fish seeds that directly depend on the quality of spermatozoa. Main purpose of the research was aimed at investigated the semen quality of nilem fish based on its different body size through investigated the characteristic of semen by microscopic evaluation such as volume, pH, pigment and consistency. Furthermore microscopic evaluations are concentration, motility, motility length and identified its morphology and morphometric spermatozoa. The result of microscopic evaluation showed the pigment of semen of nilem fish was pale white by the value of pH was 6,4 and the consistency result was thick for both fish measuring <180 mm and >180 mm. Then the average volume of <180 mm fish was 0.17 ± 0.10 ml, fewer than >180 mm fish, which was 0.34 ± 0.18 ml. Moreover, the result of microscopic evaluation showed that >180 mm fish has better result in terms of its motility, motility length and concentration showed 83.89 ± 2.20 %, 89.11 ± 25.63 seconds and 1.8588 ± 0.4970 109 ml. Meanwhile <180 mm fish were 82.22 ± 2.64 %, 63.44 ± 18.80 seconds and 1.6420 ± 0.4245 109 ml and the result of its morphology and morphometry were not showed really difference. The application that could be given is Criyopreservation technique.

Judul: Effect of Different Salinity on Physiological  Response and Growth of Bonylip barb (Osteochilus vittatus)
Abstrak: Salah satu faktor lingkungan yang dapat memengaruhi perkembangan benih ikan air tawar adalah tekanan osmotik media yang dinyatakan dalam bentuk parameter salinitas, karena salinitas berpengaruh terhadap kelangsungan hidup dan pertumbuhan benih ikan. Penelitian ini bertujuan menganalisis efek salinitas terhadap respon fisiologis, kelangsungan hidup dan pertumbuhan benih ikan nilem (Osteochilus vittatus). Rancangan percobaan yang digunakan berupa rancangan acak lengkap (RAL) dengan tiga kali ulangan pada setiap perlakuan salinitas yang berbeda, yaitu 0 ppt, 2 ppt, 4 ppt, 6 ppt, dan 8 ppt. Penelitian ini menggunakan benih ikan nilem berukuran 5,43±0,01 cm dan 1,89±0,02 g. Hasil penelitian ini menunjukkan bahwa salinitas 0 sampai dengan 8 ppt dapat ditoleransi oleh benih ikan nilem dan berpengaruh terhadap parameter pertumbuhan. Selama waktu pemeliharaan, diperoleh perlakuan terbaik yaitu pada salinitas 4 ppt dengan pertumbuhan bobot mutlak sebesar 0,90 g, pertumbuhan panjang mutlak sebesar 0,68 cm, tingkat pertumbuhan spesifik sebesar 1,79%, dan tingkat kelangsungan hidup sebesar 100%. Salinitas media di atas 4 ppt mengakibatkan ikan mengalami stres yang ditunjukkan dengan meningkatnya kadar kortisol., One of the environmental factors that can affect the development of freshwater fish seeds is the osmotic pressure of the media which is expressed in the form of a salinity parameter, because salinity affects the survival and growth of fish seeds. This study aims to analyze the effect of salinity on physiological responses, survival and growth of Bonylip barb (Osteochilus vittatus) seeds. The experimental design used was a completely randomized design (CRD) with three replications for each different salinity treatment, namely 0 ppt, 2 ppt, 4 ppt, 6 ppt, and 8 ppt. This study used Bonylip barb seeds measuring 5.43 ± 0.01 cm and 1.89 ± 0.02 g. The results of this study indicate that a salinity of 0 to 8 ppt can be tolerated by Bonylip barb seeds and affects growth parameters. During the maintenance period, the best treatment was obtained at 4 ppt of salinity with an absolute weight growth of 0.90 g, an absolute length growth of 0.68 cm, a specific growth rate of 1.79%, and a survival rate of 100%. Media salinity above 4 ppt causes fish to experience stress as indicated by increased cortisol levels.
