Abstrak

Abstrak Penelitian bertujuan untuk mengetahui dan mempelajari pengaruh padat tebar yang berbeda terhadap pertumbuhan dan sintasan benih A. percula. Desain penelitian menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari 4 perlakuan, yaitu perlakuan A (30 ekor/ 30 liter), perlakuan B (60 ekor/ 30 liter), perlakuan C (90 ekor/ 30 liter) dan perlakuan D (120 ekor/ 30 liter) masingmasing perlakuan diulang sebanyak 3 kali selama 50 hari masa pemeliharaan. Ikan dipelihara menggunakan wadah akuarium dengan ukuran 40 x 40 x 40 cm. Hasil penelitian menunjukkan bahwa A. percula yang dipelihara dengan kepadatan tebar berbeda menghasilkan pertumbuhan dan kelangsungan hidup (SR) tertinggi pada padat tebar 30 ekor/ 30 liter dengan pertumbuhan berat mutlak sebesar 0,75 gr; panjang mutlak 1,82 cm; laju pertumbuhan harian 0,015 gr/ hari dan SR 100%. Sedangkan pertumbuhan dan kelangsungan hidup (SR) terendah diperoleh pada padat tebar 120/ 30 liter ekor menghasilkan pertumbuhan berat mutlak sebesar 0,37 gr; panjang mutlak 0,91 cm; laju pertumbuhan harian 0,007 gr/ hari dan SR 91%. Berdasarkan analisis ragam, kepadatan tebar yang berbeda memberikan pengaruh nyata terhadap pertumbuhan mutlak dan laju pertumbuhan harian A. percula, tetapi tidak memberikan pengaruh nyata terhadap kelangsungan hidup dari A. percula. Kata kunci : padat tebar, A. percula, pertumbuhan, dan SR. Abstract The aim of research as to study the effect of fish density on different solid stocking on growth and survival of A. percula. The research design using Complete Randomized Design (CRD) consisting of four treatments, ie treatment A (30 fish/ 30 litre), treatment B (60 fish/ 30 litre), treatment C (90 fish/ 30 litre) and treatment D (120 fish/ 30 litre) of each treatment was repeated three times during the 50-day maintenance period. Maintained using aquarium fish which size of 40 x 40 x 40 cm. The results showed that A. percula maintained with in different stocking densities, stocking on 30 fish/ 30 litre produced an absolute growth of 0.75 grams; absolute length 1.82 cm; daily growth rate of 0.015 grams/ day and SR 100%. 120 fish/ 30 litre produce dispersive solid growth in the absolute weight of 0.37 grams; absolute length of 0.91 cm; daily growth rate of 0.007 gr/ day and 91% SR. Based on the analysis of variance of different stocking densities significant showed on the growth of absolute and daily growth rate of A. percula, but no significant effect on survival of A. percula. Key words: dense stocking, A. percula, growth, and SR.
