Abstract

The aim of this research was to know the impact of addition of ammoniak in different concentration in the sperm on the percentage of egg ovulation. The research method was carried out by completely randomized design with four treatments and three replicates, respectively. Those treatments were the addition of ammoniac solution with concentration of 0% (treatment A), 0.005% (treatment B), 0.010% (treatment C), and 0.015% (treatment D). The data was analyzed by using ANOVA and Duncan’s Multiple Range Test to know the effect of between the other treatments. The results showed that was the highly significant difference effect (p<0.01) on the egg ovulation of Abalone (H. asinina). The highest egg ovulation rate was obtained in treatment B (94.67% ). The ovulation rate was significantly higher than those in treatments C, D, and A, respectively. According to the results, the best concentration of the ammonia solution to the abalone sperm added was 0.005%. Furthermore, the regression test also showed a positive, linear relationship between spermatozoa motility rate and egg ovulation rate. However, the analysis of orthogonal polymonial provided a ammonia solution with the highest ovulation rate of 0.0057%.  Keywords: Concentration, ammonia solution, ovulation egg, abalone, H. asinina

Abstract

Usaha budidaya ikan di perairan payau dan laut semakin berkembang dan tidak dapat terlepas dari tahap pembenihan. Diperlukan budidaya benih dengan pemberian pakan alami yang cukup dan berkualitas. Pakan alami belum dapat digantikan oleh pakan buatan terutama pada saat awal pemeliharaan larva. Salah satu jenis pakan alami adalah Chlorella sp. yang diberikan kepada jenis zooplankton maupun langsung kepada kultivan ikan atau udang. Media kultur Walne, Gullard’s f/2 dan Erdschreiber merupakan media yang cocok digunakan untuk mengkultur phytoplankton. Tujuan penelitian adalah mengetahui pengaruh penggunaan media Walne, Gullard’s f/2 dan media Erdschreiber terhadap pertumbuhan Chlorella sp dan mengetahui media terbaik dari ketiga media tersebut terhadap pertumbuhan Chorella sp. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap dengan 3 perlakuan dan 3 kali ulangan, yaitu perlakuan A menggunakan Media Walne, perlakuan B menggunakan Media Guillard’s f/2, dan perlakuan C menggunakan Media Erdschreiber. Hasil penelitian menunjukkan bahwa penggunaan media kultur yang berbeda berpengaruh nyata (P<0,05) terhadap waktu lag phase dan berpengaruh sangat nyata (P<0,01) terhadap konstanta pertumbuhan spesifik, puncak populasi dan kepadatan akhir Chlorella sp. Media Guillard f/2 memberikan pertumbuhan Chlorella sp terbaik dengan waktu lag phase tercepat (0,290 hari), konstanta pertumbuhan spesifik terbaik (0,655), puncak populasi tertinggi (8,53 x 107  sel/ml) dan kepadatan akhir tertinggi (2,77 x 106 sel/ml)   Kata Kunci : media, kultur, pertumbuhan, Chlorella sp

Abstract

The Objective of the research was to know the effect of live food enrichment of rotifer with squid egg extract on the growth patterns and quality of rotifer, especially the EPA and DHA contents. The experiment method was employed in this research and it carried out in the aquaculture laboratory, Faculty of Fisheries and Marine Sciences, Diponegoro University. The research planning was a completely randomized design with five treatments and three replicates, respectively. The recording data was analyzed to get the variables of rotifer growth patterns and the most of rotifer samples were analyzed EPA and DHA contents in the chemical and biochemical laboratory center, Gajah Mada University. The results showed that the addition of squid egg extract in the culture media of rotifer was highly significant effect (p<0.01) on the specific growth rate, the maximal density, and the final density of rotifer culture. However, there was also highly significsnt effect (p<0.01) on the nutrition quality through EPA and DHA contents. To increase the quantity and quality of rotifer, B. plicatilis O.F. Muller in the culture was addition of squid egg extract of 1,2 g/1 million ind. Rotifers during twelve two hours in the rotifer culture. Key word : Rotifer, Brachionus plicatilis O.F. Muller, enrichment, quantity and quality, EPA dan DHA
