PENGARUH PADAT TEBAR YANG BERBEDA TERHADAP KELANGSUNGAN HIDUP DAN PERTUMBUHAN BENIH IKAN MAS (Cyprinus carpio L) PADA SISTEM RESIRKULASI DENGAN PENAMBAHAN ZEOLIT

Abstract

The purpose of this research was to analyzed rearing density producing the best survival and growth rate of fish Cyprinus carpio L   from resirculation with zeolit. It was chosen by using experimental with a completely randomized design. It was consisted of  4 treatments and 3 replicates. A treatment 1 fish/L, B treatment 2

Fish/L, C treatment 3 fish/L, and D treatment 4 fish/L. The sample of this research was Cyprinus carpio L fish, the total number of sample was 900 fish, old 1 – 2 monts. The container used 12 aquarium with size 45 x 32 x 30 cm from  reserculation with 1,

8 kg   zeolit/aquarium.   The result of this research shows that the use of different density producing gives no real contribution towards survival and growth of Cyprinus carpio L. the real highest weight found on B Treatment (1, 21 ± 0, 58 gr), the real highest length found on B treatment (1, 00 ± 0,43 cm).
